Abstract

A catheter tunneling assembly (100) used to tunnel a distal end of a multilumen catheter assembly (200) through a subcutaneous tunnel prior to inserting the catheter assembly into a patient. Adapter (130) facilitates connection of a trocar (110) with the catheter assembly and provides a smooth transition. The adapter has an inner member (130) that is affixed to the proximal end (114) of the trocar (110) and includes a proximal projection (134) that coextends along a distal portion of the catheter assembly (200); and an outer member (160) that is slidable from distally of the inner member to surround the proximal trocar end, the inner member (130) and a distal portion of the catheter assembly (200) pressing the proximal projection (134) of the inner member (130) into frictional engagement with a catheter portion. A method includes providing a tunneler assembly having a body (100,130) with a first and second extensions (126,134), and a slider (160); inserting the first extension into a catheter lumen; and sliding the slider (160) along the body toward the catheter to surround the tunneler assembly body and catheter end and bias the second extension (134) toward the first extension (126) to frictionally engage the catheter portion therebetween.
