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 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 multiple catheter assembly including first and second catheters. The first catheter includes a first catheter outer surface defining a first lumen, a first distal end terminating in a first distal tip, and a first transition region. The second catheter includes a second catheter outer surface defining a second lumen, a second distal end terminating in a second distal tip, and a second transition region. At least a portion of each of the first and second catheters resides in a cannulating portion. The first and second transition regions of the first and second catheters transition cross sections of the first and second catheter outer surfaces at the first and second distal tips to cross sections of the first and second catheter outer surfaces in the cannulating portion. In exemplary embodiments, the portions of each of the first and second catheters in the cannulating portion are releasably bonded to one another.
