An electrode assembly for a catheter having first and second conductors comprises an anode ring including an outer portion and an inner portion connected to the outer portion. The inner portion includes a solid member having a blind passage therein and a channel therethrough. One end of the first conductor is received in the blind passage and retained therein by a pair of crimps impressed into the solid member against the conductor end. The second conductor extends through the anode ring in the ...

A catheter comprising, an extruded tube having a drainage lumen and inflation lumen, with the inflation lumen communicating with the outside of the tube through an opening. The catheter has a tip secured to a distal end of the tube, and an annular sleeve extending from the tip and having a proximal end secured to the outside of the tube.

A catheter to be electrically connected to a part of an organ of a body, typically, the muscle of the heart. The catheter includes a hollow electrical conductor having a resilient clamp at the end where it is to be connected. The clamp is manipulated by a manipulator which is removably inserted into the conductor or by a string which is permanently connected to the clamp. The jaws of the clamp are normally maintained closed by a spring. The spring is retracted by the manipulator or string which ...

A catheter having a shaft including a drainage lumen and an inflation lumen is provided with a molded connector unit bonded to its proximal end, the connector unit including a drainage fitting and an inflation side arm. A rigid adapter tube has its forward end extending into the drainage lumen and its rearward end seated against the drainage fitting to seal the drainage lumen and fitting from the side arm and inflation lumen; the adapter tube provides communication between the drainage lumen and...

The invention concerns a catheter for intravascular application, comprising a shaft extending along the catheter longitudinal axis from the proximal end to the distal end and having a fluid-tight shaft wall and at least one lumen which is adapted to guide a fluid and at least one electrically conductive wire which extends from the proximal end at least into the proximity of the distal end of the catheter along the catheter longitudinal axis. The catheter is characterized in that on at least one ...

A catheter having a body made from elastomeric material and including a tubular inner part defining a fluid passageway having an inlet end and an outlet end. A tubular outer retention sleeve integrally connected only at the inlet end to the inner part extends in the direction of the outlet end in axially surrounding relation to the inner part. The retention sleeve is biased to a normal retention configuration for engaging the peripheral wall of an associated body passageway to releasably retain ...

An enteral feeding catheter (5) that provides access to both the stomach and the jejunum for feeding, aspiration and decompression. The catheter includes a dual lumen "D" tube (30) that joins to an external "Y" connector (25) at the proximal end of the tube. The connector serves both lumens as a source for fluid or aspiration. The gastric lumen (37) and the jejunal lumen (38) of the "D" tube both connect to a transitional connector bolus in the stomach. The gastric lumen of the "D" tube joins wi...

The catheter provided in accordance with aspects of the present invention includes an elongate tube having a proximal tube portion and a distal tube portion formed by stretching the distal portion of the elongate tube. The catheter is made throughout from an identical material. The distal tube portion has a reduced outer diameter and thus is of a higher flexibility and softness. Therefore, the danger of injuries to vessels or the dura is decreased. The catheter can be produced in an inexpensive ...

A catheter includes a main body; a first and a second lumen provided in the main body, wherein a first and a second guide wire are insertable in the first and second lumens, respectively; a first inclined surface provided, on a side of the center axis line, such that the first inclined surface is inclined frontward to approach the center axis line; a first opening formed in the first inclined surface and through which the first lumen opens outward; a second inclined surface provided, on the othe...

A catheter constituted of a single-pipe tube, and provided with a tip end portion (10) implanted in an abdominal cavity and a projection portion (12) projecting outward from the outer wall of the abdomen. A pair of cuffs (16, 18) are attached to the projection portion (12) and a reinforcing tube (14). Side holes (20) are drilled in the tip end portion (10), and each side hole is allowed to communicate with each other along the axial direction of the single-pipe tube by means of a groove (22) for...
