A method of treatment including positioning the part of the patient or animal to be treated between the poles of an electromagnet. The part is then subjected to a pulsating magnetic field induced in the electromagnet by an intermittent direct current, the peak intensity of each pulse being at least 2,000 gauss. Preferably each pulse has a duration of at least 1/4 second, and about one pulse per 1/2 second is administered.

An apparatus for treating a patient which induces an electric current in the body through external application of an electromagnetic field. The apparatus includes means for controlling the magnitude of the induced electric current by sensing the electromagnetic field and automatically controlling its strength. The sensing may be accomplished through time multiplexed use of the field inducing coil or through the use of a separated, dedicated coil.

A miniature surgical instrument that is particularly useful for removing ferrous foreign particles from an eye, includes a housing and a wire wound coil positioned within the housing. A magnetizable, axially elongated probe includes a first tip portion that is positioned externally of the housing and a second, body portion that is within the housing and which is surrounded by the coil. A switch is coupled to the coil and is adapted to interconnect the coil to a source of electrical energy so tha...

The present invention relates to the construction of a magnetic medical treatment member comprising a flat magnetic press element mounted upon a sticking surface of a sticking member for providing simultaneously a finger-pressure effect and a magnetic medical treatment effect. The conventional magnetic medical treatment member of this type has such a construction that a plurality of projections for locally stimulating a surface of skin are mounted on a surface of a flat magnetic press element ne...

Disclosed is a method for staunching blood flow from an acutely bleeding gastrointestinal lesion. The method comprises introducing, into the gastrointestinal tract, a tamponading mass having ferromagnetic properties. A suitable tamponading mass is a mixture of finely divided iron particles and vegetable oil which may be introduced through an endoscopic catheter. Once in the gastrointestinal tract, the tamponading mass is moved as necessary to cover and press upon the bleeding lesion by a magneti...

This ocular decompression process is a surgical procedure and a physical therapy for the alleviation of glaucoma. The invention contemplates a surgical operation on the eye, at which a metallic implant is introduced through the sclera into or adjacent to the anterior chamber of the eye. The extra-cameral portion of the implant, fashioned into a loop, is buried under fibrous and epithelial tissue. After the surgical incisions have healed, the coil of a tuned radio-frequency circuit is brought int...

This invention incorporates the discovery of new principles which utilizes magnetic fluxes generated by time varying square wave currents of precise repetition, width, shape and magnitude to cause them to move through multi-turns of conductive material generally in the form of a coil, in order to stimulate the cardiovascular system in humans or animals by directing the fields externally through the chest wall or the skull in order to correct arrhythmias and/or heart blocks. The new method of car...

The invention contemplates a specific coil configuration adapted for application to particular regions of the body, for use in treating a selected such region with pulsed electromagnetic signals which are induced within the body as electric voltage and concomitant current signals which alter the growth, repair and maintenance behavior of living tissues and cells within the body region under treatment.

Induction heating can be utilized to cause necrosis of neoplasm as a result of hyperthermia by a process involving the injection of particles having hysteresis heating characteristics into tissue either within or in close proximity to the neoplasm and then subjecting these particles to an alternating magnetic field sufficient to cause hysteresis heating. The frequency of the field is preferably sufficiently low so as to minimize eddy current and dielectric heating. The particles used are prefera...

An adjustable valvuloplasty ring that comprises a C-shaped frame that is sized and shaped to extend about the circumference of the left atrioventricular orifice along the base of the anterior cusp of the mitral valve; an expandable sleeve connected to the frame that together therewith forms a closed annulus, the sleeve being adapted to extend about the remainder of the circumference of the orifice; and a drawstring running through the sleeve by which the sleeve may be contracted to constrict and...
