ABSTRACT:
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.
