BACKGROUND OF THE INVENTION
This invention relates to condom, and more particularly to a condom which
may be easily affixed even to a flaccid penis, and also to implant-type
stiffening devices.
At present, two types of condoms are known: the roll on type which rolls
over the penis; and the pull over type which is pulled over the penis.
Both of these known condoms are suitable for use only when the penis is
erect. If the penis is flaccid, for example as would be the case with an
impotent male, it is extremely difficult, if not impossible to place the
condom on the penis.
More particularly, when condoms using rheopexic fluid as a stiffening
agent, as disclosed and claimed in my copending U.S. patent application
Ser. No. 388,107, which condoms are particularly suitable for use with
impotent males, it is difficult to place the condom over the flaccid
penis.
Therefore, an object of the present invention is to provide a condom which
may be easily placed over the penis of the user, even a flaccid penis of
an impotent male.
Penile implants are presently well known. Typical penile implants are
discussed in an article entitled, "Complications of Penile Prosthesis
Surgery for Impotence" by Joseph J. Kaufman, Arie Lindner and Shlomo Raz,
The Journal of Urology, Volume 128, December, 1982, pages 1192 and 1193,
the entire contents of which are incorporated herein by reference. Penile
prosthetic devices are also discussed in the article entitled, "Penile
Prosthetic Surgery Under Local Anesthesia" by Joseph J. Kaufman, The
Journal of Urology, Volume 128, December, 1982, pages 1190 and 1191, the
entire contents of which are also incorporated herein by reference. The
known penile prosthesis is generally a semi-rigid rod or an inflatable
device. The semi-rigid rod has the disadvantage of always being
semi-rigid. The inflatable device has the disadvantage of requiring
additional structures to inflate and deflate the prosthesis. These prior
art devices are thus unsatisfactory.
Therefore, a further object of the present invention is to provide a penile
prosthesis which may be easily implanted in the penis and which is simpler
in design and operation than the prior art devices.
Yet another object of the invention is to provide a condom which may be
easily placed over the penis of the user, even a flaccid penis of an
impotent male, which condom need not include the stiffening rheopexic
material disclosed herein and disclosed in my copending application Ser.
No. 388,107. Such a condom is particularly useful with impotent males
using other penis stiffening means, and who require the use of a condom
for birth and/or disease control.
SUMMARY OF THE INVENTION
According to the present invention, a condom comprises an elongated
generally tubular member of thin, flexible material; an elongated opening
provided along at least a substantial portion of the length of the
elongated tubular member so as to facilitate placing the elongated tubular
member over a flaccid penis; and means for closing the elongated opening
after placing of the condom on a flaccid penis. Preferably, the tubular
member has chambers thereon for receiving rheopexic material to serve as a
stiffening agent.
A penile prosthesis according to the present invention comprises an
elongated generally tubular member having closed ends and defining at
least one chamber therein; and a rheopexic material in the at least one
chamber and retained sealingly within the at least one chamber; the
elongated tubular member being adapted to be implanted in a penis.

DETAILED DESCRIPTION
The condoms of the present invention preferably are generally of the type
illustrated in U.S. patent application Ser. No. 388,107. The condom is
provided with a plurality of chambers or compartments 10 illustrated in
FIG. 2, which compartments are filled with rheopexic fluid of the type
disclosed in Ser. No. 388,107, the rheopexic fluid not being discussed in
detail herein. Also, the various compartments containing the rheopexic
fluids may be of the type shown in Ser. No. 388,107, a detailed
description not being given herein since the entire contents of Ser. No.
388,107 is incorporated herein by reference. The compartments are shown
schematically in FIGS. 2 and 3, but are not shown in the other drawings of
the present application.
While the present invention is particularly useful with condoms using
rheopexic fluid therein as a stiffening agent, the concepts of the present
invention can be used with other types of condoms having other stiffening
devices and wherein the penis may be provided with an internal
implant-type stiffening device. The concepts of the present invention are
also applicable to condoms having no stiffening means per se or to condoms
having stiffening means other than those specifically disclosed herein.
The main object of the present invention is to provide a condom which can
be placed on a flaccid penis, for example by impotent males.
Referring to FIG. 1, the condom 20 comprises, for example, a condom as
shown in Ser. No. 388,107 with inner and outer layers, having rheopexic
fluid therein. The condom is further provided with an elongated opening
member 21 which may be generally of the type designated as a "zip-lock"
closure. The closure is shown in more detail in FIG. 2. The closure 21
comprises interengaging members 22, 23, the member 23 having a projection
24 thereon which engages in a recess 25 of member 22. Preferably, the
projection 24 has a protrusion 26 which engages in a concave portion 27 of
the recess 25 to provide a firm interlocking engagement of the projection
24 in the recess 25. The closure in FIGS. 1 and 2 is closed by pressing
the members 22, 23 together along the direction of the arrows A shown in
FIG. 2. This will provide a firm, liquid-tight seal along the length of
the condom, and since the condom is supplied with the locking members 22,
23 opened, the condom may be easily placed over the penis, the closure
members 22, 23 then being pressed together in the direction of the arrows
A in FIG. 2, to firmly close the condom over the penis, ready for use.
Preferably, the locking members 22, 23 are fabricated of a material which
is firmer than that of the material forming the circular part of the
condom. Also, the condom preferably has about one inch at the top thereof
which is solid or closed (not provided with the zip-type opening) for
accumulation of ejaculated spermatozoa. By providing the solid or closed
upper or head portion of the condom, the safety aspect of preventing
possible leakage of spermatozoa after ejaculation is improved.
As shown in FIG. 3, a flap, of latex or having compartments containing
rheopexic fluid, can be provided to go over the zip-type closure of FIGS.
1 and 2 to prevent irritation from occurring to the sex partner.
Preferably, the flap 30 illustrated in FIG. 3 extends upwardly above the
upper portion of closure member 22, 23 and is adhered or sealed to the
condom at 31. This insures that the flap will remain covering the closure
members 22, 23 during use, and provides a smoother outer surface of the
condom to further prevent irritation from occurring to the sex partner.
As shown in FIG. 3 an inner flap 35 may be provided to protect the male
organ from irritation due to the closure 22, 23. The inner flap 35 is
preferably generally coextensive with outer flap 30.
FIG. 4 illustrates a modified protective arrangement wherein a sleeve 40 is
slid over the condom after the condom is placed over the penis. For
example, after the condom is placed over the penis and the zip-closure
members 22, 23 are pressed together to close same, the sleeve 40 is then
slipped over the closed condom to serve as a protection layer to prevent
irritation to the sex partner.
FIG. 5 illustrates an improved arrangement of providing a circular sleeve
over the condom for protective purposes. In FIG. 5, the sleeve 50 is
integrally formed at the upper portion 51 of the condom with the outer
surface of the condom so as to provide a smooth junction which will not
irritate the sex partner. The sleeve 50 is rolled up, as shown in FIG. 5.
After closure of the zip closure members 22, 23, the sleeve 50 is then
rolled downwardly to completely cover the zip closure member in a secure
and positive fashion. FIG. 6 illustrates the roll-down sleeve 50 at an
intermediate position, it being clear that sufficient material is provided
in the roll-down sleeve 50 to permit it to be rolled all the way down to
the base of the condom.
In the above embodiments, it should be clear that the zip-closure members
22, 23 are tapered at the upper ends or at the head portion of the condom,
as shown in FIG. 1, to further prevent irritation to the sex partner. This
is shown by means of inclined surfaces 28 in FIG. 1.
FIG. 7 illustrates a modified embodiment wherein the closure comprises a
plastic slide fastener device 60 utilizing a conventional slide 61 for
closing the plastic slide fastener. The plastic slide fastener members 62,
63 are integrally formed with edges 64, 65 of the condom, as are the
closure members 22, 23 with the edges of the condom 20 shown in FIG. 1.
The slide fastener 60 is of convention construction and is shown in detail
in FIG. 8. To use the condom of FIG. 7, the condom, in its open state, is
placed over the flaccid penis, and the slide 61 is pulled downwardly
toward the base of the penis to firmly close the plastic slide fastener
60. The slide 61 can be removed completely from the condom at the base
portion of the condom, or a stop member 66 can be formed at the bottom of
the condom to prevent the slide 61 from coming off the base of the condom.
This arrangement will permit the slide fastener 60 to be re-used, thereby
permitting the condom to be re-used, as desired. If the stop members 66
are provided to prevent the slide 61 from coming off the end of the
members 62,63, it is desirable that some type of protective device be
provided at the base of the condom to prevent the retained slide 61 from
irritating the sex partner. A suitable device is a sleeve such as shown in
FIG. 4, but the sleeve not being as long as the sleeve of FIG. 4 since it
is only necessary to cover the lower end portion of the slide fastener 60.
Also, in this embodiment, it is preferable to use a flap such as flap 30
to protect the sex partner from irritation by the slide fastener 60.
Sleeve 40 of FIG. 4 could also be used for protective purposes. The
roll-down sleeve 50 of FIGS. 5 and 6 could also be used, this arrangement
being very advantageous since it will also "roll" relatively easily over
the slide 61 at the base portion of the condom to serve as a protector
shield therefor.
As seen in FIG. 7, a flap 80 can be integrally formed with the lower
portion of the condom 67, the flap 80 having an adhesive portion 81
covered by a release material (such as a release paper) 82. In use, when
the 61 is zipped down to the bottom of the condom, the relase paper 82 is
removed and the flap 80 is placed across the bottom portion of the condom,
over the slide 61, and adhered to the opposite side of the condom, thereby
covering the slide 61 and also securely locking the condom in its closed
position to prevent inadvertent opening thereof. Such a flap 80 can also
be provided in the embodiment of FIGS. 1 and 6 to insure that the bottom
portion of the condom will remain closed. The flap 80 in the embodiment of
FIGS. 1 and 6 is not illustrated in the drawings, but it can be
implemented in substantially the same way as shown in FIG. 7. The inner
and outer flaps 35, 30, respectively, shown in FIG. 3 may have adhesive
portions along their longitudinal vertically extending free edges, the
adhesive material being covered by a release paper or the like. During
use, the free ends of the flaps 30 and/or 35 can be adhered to the
remaining portion of the condom, if desired. It is generally not necessary
to provide an adhesive for the inner flap 35 since it will be retained in
place by the pressure of the condom on the penis. If adhesive securing of
the free edge of a flap is desired, it is generally preferable to use it
in connection with outer flap 30.
FIG. 9 illustrates a further modified embodiment wherein the slide fastener
60 is turned at right angles at the base portion of the condom so that
after the slide 61 is pulled down, the slide is retained in a horizontal,
rather than vertical position relative to the penis. A protective sleeve
70 is provided at the base portion of the condom to serve as protection
from irritation of the partner by the slide 61. The sleeve 70 is shown
outwardly spaced from condom 68 in FIG. 9 for ease of illustration, but
preferably it is of elastic material and is tightly formed against the
main body of the condom 68. In the embodiment of FIG. 9, the roll-down
sleeve 50 of FIGS. 5 and 6, is used. Alternatively, the slip-on sleeve 40
of FIG. 4 or the flap 30 of FIG. 3 can be provided either with or without
the upwardly directed lower sleeve 70, for protective purposes. Still
further, as seen in FIG. 10, the sleeve 70 can be provided in a roll-up
manner, such as the roll-down sleeve 50 of FIGS. 5 and 6. In FIG. 9, after
the slide 61 is slid down to the base of the condom 68, the roll-up sleeve
71 is rolled upwardly, as shown in chain lines, to cover the slide 61. The
sleeve 71 is of elastic material and preferably tightly encircles the base
of the condom so as to securely cover the slide 61.
In the embodiments of FIGS. 9 and 10, since a fixed member is located at
the base of the condom, it is more difficult to insert the condom onto a
flaccid penis than the embodiments discussed previously. However, if the
slide fastener device for the elongated opening of the condom is in the
open state during insertion of the penis, it is still possible to
relatively easily insert the condom over the penis since the user can
extend his fingers through the elongated open closure and pull the flaccid
penis through the lower members 70 or 71 (FIGS. 9 and 10, respectively).
After the penis is pulled through the lower portion 70, 71, then the
condom can be closed in the longitudinal direction, as discussed
hereinabove.
Once the condom of the present invention is placed on the penis, a "pseudo
erection" can take place by means of the rheopexic material such as
disclosed in Ser. No. 388,107, or by other means which may be provided
either within the condom or within the penis of the user.
Any of the condoms of FIGS. 1-10 may be rheopexic fluid receiving chambers
(as seen in FIG. 2) or such chambers may be eliminated. When the chambers
are eliminated, the condom may be a single layer condom having the same
opening and closing constructions as shown in FIGS. 1 and 3-10 to aid in
placing the condom over a flaccid or semi-flaccid penis. Such a condom may
have stiffening means other than rheopexic fluid or may have no stiffening
means at all. Penile implants, such as those already known or those shown
in FIGS. 11-13 may be used with such condoms which have rheopexic fluid
receiving chambers as shown in FIG. 2.
FIG. 11 shows a penile prosthesis which is implanted in a penis. FIG. 11
shows two penile prostheses 100, 101, which prostheses are generally
elongated tubular members having rheopexic material therein. FIG. 12 shows
a broken view of a typical prosthesis 100 with rheopexic fluid 102
therein. The advantage of the penile prosthesis of FIGS. 11 and 12 is that
in the normal state, the tubular prosthesis 100 is generally flaccid. In
an agitated state, the rheopexic material within the prosthesis 100, 101
will stiffen the prosthesis 100, 101 due to the characteristic of
rheopexic materials, thereby providing a "psuedo erection". Upon cessation
of stimulation, the rheopexic material will revert back to its normal,
non-agitated state and the penis will then again become flaccid. These are
precisely the characteristics required of a penile prosthesis.
The details of implanting a penile prosthesis of the present invention into
a penis is not given herein since such details are known, as is evident
from the two articles entitled "Complications of Penile Prosthesis Surgery
for Impotence" and "Penile Prosthetic Surgery Under Local Anesthesia",
which were mentioned hereinabove. The tubular members 100, 101 can be made
of inert, flexible biologically safe materials, such as polypropylene or
similar materials so as to contain the rheopexic material in a leak-proof
or liquid-tight state. Similar materials as are used for inflatable penile
prostheses can be used for the elongated tubular members 100, 101 of the
present invention.
The elongated prosthesis shown in FIGS. 11 and 12 can be provided with
compartments or chambers therein, such as shown in FIG. 13. For example, a
longitudinally extending divider 103 can be provided internally of the
prosthesis 100 to divide same into upper and lower compartments 104, 105,
each of which is sealed off from each other and each of which is filled
with rheopexic material 102. The prosthesis of FIG. 13 can also be divided
into adjacent longitudinally extending compartments by providing internal
dividers 106 which extend vertically in FIG. 13. The longitudinal divider
103 and/or the vertically extending dividers 106 can be provided, as
desired, depending upon the characteristics required and the type of
rheopexic material used.
