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 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 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.
