摘要： Catheter assembly (100) having at least one lumen (150 or 160) and joined to hub (106). While the lumen inner diameter(s) remain constant from distal end (144) of the catheter (140) to proximal end (142), the outer catheter diameter increases proximate the hub (106) providing increased resistance to kinking during connection and disconnection from medical apparatus. The increased proximal catheter diameter preferably is sufficiently large to plug the proximal end of an introducer sheath through which the catheter is inserted during patient placement, to plug the proximal sheath end and minimize blood aspiration therethrough, and later serves to fill the vascular insertion upon complete catheter insertion after removal of the introducer sheath again to minimize blood aspiration through the vascular incision. The catheter may have two lumens (150,160) or more, joined to respective extension tubes in hub (106). The two lumens may each have a respective inner diameter of between about 0.020 in and 0.025 in. The catheter body may have a lengthy distal portion vascularly implanted having an appropriate outer diameter for the vessel, and also a lengthy proximal portion with a larger diameter for resistance to kinking at a sharp bend between the vascularly implanted portion and the subcutaneously tunneled lengthy proximal portion.

摘要： A multilumen catheter assembly 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 circular shape in cross section and is attached to the at least two distal end tubes. In one embodiment, the catheter assembly may be made by extruding a unitary tube having internal longitudinally extending lumens, then splitting the unitary tube at a distal end portion of the unitary tube to form the at least two distal end tubes. The at least two distal end tubes are then ground and polished. In another embodiment, the catheter assembly may be made by extruding the at least two distal end tubes and permanently bonding proximal ends thereof to form the unitary portion.

摘要： An inflatable gastric band incorporates a fluid channel within an outer surface of the band and an inflatable bladder on a stomach-facing side of the band. The gastric band attaches to a double lumen catheter, which communicates with a dual infusion port. One lumen communicates with the fluid channel and one port, while the other lumen communicates with the inflatable bladder and a second port. Injection of fluid into one chamber of the infusion port expands inflatable bladder, allowing adjustment to the diameter of the stoma. Injection of drugs or therapeutic agents into the second chamber allows the infusion of drugs or agents directly into the abdominal cavity of a gastric band recipient. The inflatable bladder can be continuous or segmented. A segmented bladder reduces pinching and/or folding of the inner surface of the gastric band during expansion/contraction, thereby lessening stomach pinching and/or irritation.

摘要： A method of making a multilumen catheter assembly to include 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 circular or oval shape in cross section and includes at least two distal end tubes of generally semi-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 semi-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 cross sectional shape of the unitary extrusion, or the finished tubes can each be finished to another cross sectional shape, or the finished tubes could include a combination of cross sectional shapes over their longitudinal lengths.

摘要： A venous access port assembly having a housing base, a flange, and a septum. The housing base defines an interior reservoir. The flange includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the flange from a top surface to a bottom surface of the flange. According to one aspect, the flange may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material of the flange, or they may be formed by voids in the X-ray discernable material. According to another aspect, the flange may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the flange applied with the radiopaque agent.
