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： PROBLEM TO BE SOLVED: To provide advantage of a multilumen catheter with respect to easy insertion and advantage of a multiple catheter assembly which prevents potential risk of leakage at the site of vessel entry.SOLUTION: A unitary portion 12 includes an exterior having a generally round or oval shape in cross section and includes at least two distal end tubes 14, 16 of generally circular cross sectional shape extending longitudinally therethrough. The catheter assembly 5 may be made by extruding a unitary 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, the finished tubes retaining in combination of 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 may include a combination of cross sectional shapes over its longitudinal length.

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 o cross sectional shapes over its longitudinal length.
