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： 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 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 multiple lumen catheter assembly and methods for inserting the same are provided. The assembly includes a splittable membrane joining a first catheter and a second catheter for allowing the catheters to be at least partially longitudinally split from each other. Each catheter has at least one lumen extending longitudinally through the catheter. One method for inserting the assembly includes making an incision near the area to be catheterized, at least partially splitting the distal end regions of the catheters from each other by splitting apart the splittable membrane, and inserting the distal end regions of the catheters in a juxtaposed relation through the incision and into the area to be catheterized. In another method, the catheters are first tunnelled subcutaneously by pulling the distal end regions of the catheters in the assembly through a tunnel and outwardly from the tunnel near the area to be catheterized, leaving proximal end regions at least partially within the tunnel. An incision is made near the area to be catheterized, the distal end regions of the catheters are at least partially split from each other by splitting the splittable membrane, and the distal end regions of the catheters are inserted in a juxtaposed relation through the incision and into the area to be catheterized.

摘要： A subcutaneous tunnelling device, a dilator and a method of forming a subcutaneous tunnel are provided. The device includes a trocar having a front end with a point configured for piercing skin, and a dilator which has a front end removably attached to the rear end of the trocar. The dilator is for dilating a section of a subcutaneous tunnel and includes a dilating section having a maximum diameter sized for dilating an interior surface of a subcutaneous tunnel for seating a catheter stabilizing cuff in the subcutaneous tunnel. The method of forming a subcutaneous tunnel includes the steps of inserting a trocar through a first location on a cutaneous surface and moving the trocar through subcutaneous tissue to form a subcutaneous tunnel. The trocar is at least partially removed and a front end of a dilator is attached to the trocar. A section of the tunnel is dilated by moving the dilator partially through the tunnel until the front end of the dilator reaches a first subcutaneous location in the tunnel. The dilator and trocar are at least partially withdrawn from the dilated tunnel section of the subcutaneous tunnel through the first end of the tunnel.

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： 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.
