摘要： A self-retaining catheter assembly is provided which includes a first and second catheter and a retaining sleeve. The first and second catheters each have an exterior surface and an interior surface defining a lumen which extends longitudinally through the catheter. The first catheter has a proximal portion which is for placement within a first subcutaneous area, and the second catheter has a proximal portion which is for placement within a second subcutaneous area. The first and second catheters also each have distal portions for placement within an area to be catheterized. The retaining sleeve is positioned around a portion of the exterior surfaces of the catheters which is located proximal to the distal portions of the catheters. The portions of the exterior surfaces of the catheters within the retaining sleeve are in a juxtaposed relationship and the retaining sleeve is positioned such that when the distal portions of the first and second catheters are within the area to be catheterized, the retaining sleeve is outside the area to be catheterized and distal to the first and second subcutaneous areas, and the assembly is secured in place.

摘要： A cutting balloon catheter assembly (100) including a dual lumen catheter (130) having a distal end (134), an inflation/deflation lumen (138) and a second or guidewire lumen (136). The assembly further includes an inflatable balloon (110) having an interior cavity (116) and an expandable covering (120) disposed about the balloon wherein the covering has an array of cutting edges.

摘要： A multilumen catheter assembly is provided, which includes a unitary portion and at least two distal end tubes extending distally from the unitary portion. The unitary portion includes an exterior having a generally round or oval shape in cross section and includes at least two distal end tubes of generally circular (or other) cross sectional shape extending longitudinally therethrough. The catheter assembly may be made by extruding a unitary tube having internal longitudinally extending lumens (of circular or other shape), then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished, the finished tubes retaining in combination the generally oval cross sectional shape of the unitary extrusion, or the finished tubes can each be finished to a circular, or other, cross sectional shape, or the finished tubes could include a combination of cross sectional shapes over its longitudinal length.

摘要： A dilator (100) for expanding a vessel incision to assist insertion of a catheter thereinto and having a distal end (104) and a proximal end (106). The dilator has two portions (110,210) that are assembled together at a hinge (112,212) permitting angled-apart proximal ends (122,222) of the two portions at the proximal end (106) to be squeezed together about the hinge which slightly spreads apart the respective distal ends (114,214) of the two portions to enlarge the incision into the vessel. A spring (150) biases apart the proximal ends of the two portions to maintain the two distal ends (114,214) together until pried apart as desired to dilate the vessel incision.

摘要： A multilumen catheter assembly and methods for making and inserting the same are provided. The catheter assembly includes a unitary catheter and at least two distal end tubes which extend distally from the unitary catheter. The at least two lumens in the unitary catheter are in fluid communication with passageways through the distal end tubes. The catheter assembly may be made by extruding a unitary catheter tube having internal longitudinally extending lumens, then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished to form a smooth surface on the exterior of the tubes. The catheter assembly may also be made by forming an outer layer on at least two longitudinally extending catheters while leaving two distally extending portions of the tubes outside the outer layer to form the distal end tubes. The multilumen catheter assembly may be inserted in a patient for acute and chronic catheterization and subcutaneously tunneled and inserted using a single insertion procedure while leaving the distal end tubes within the vessel capable of free movement and sealing the insertion site into an area to be catheterized.

摘要： A port (100) for a catheter assembly (200), including a body (102) and a cover (150) and having a distal discharge port (116) for connection to an implanted catheter assembly. Within the body is a longitudinal U-shaped channel (120) extending to a proximal body wall (104) from the distal body wall (106) along a longitudinal axis parallel to the axis of the discharge port (116). The channel has a rounded bottom (122) and is also rounded at the channel ends (126,124) at the distal and proximal body walls. The cover (150) provides for penetration by a syringe needle and seals upon needle withdrawal, with the cover having an inside surface (152) that is concave and rounded between the distal and proximal ends and also longitudinally, being generally smoothed into the channel sides and ends. The port has no inner sharp edges or corners and eliminates blood clotting and unwanted growth sites.

摘要： A multiple catheter assembly is provided. The assembly includes a first catheter constructed from a first material and having a first proximal end region, a first distal end region terminating in a first distal tip, and an outer surface defining at least a first lumen extending longitudinally therethrough between a first distal and a first proximal opening. The first proximal end region is integrally connected to an extension tube constructed from a second material. A second catheter is constructed from the first material and having a second proximal end region, a second distal end region terminating in a second distal tip, and a second outer surface defining at least a second lumen extending longitudinally therethrough between a second distal and a second proximal opening. The second proximal end region is integrally connected to an extension tube constructed from the second material. The first lumen and the second lumens are independent from each other for facilitating simultaneous flow in opposite directions. The outer surfaces of the first and second catheters are releasably joined for allowing the first and second distal tips to be at least partially longitudinally split from each other.
