Abstract: Lead body designs for forming a fluid tight seal between a multilumen tube and other portions of a lead body are provided. One lead body design has a multilumen tube having a first portion defining a first number of lumens and a second reduced dimension portion defining a second number of lumens, the second number of lumens being smaller than the first number of lumens. The reduced dimension portion is attached to a distal tip portion of the lead body, forming a fluid tight passageway through the multilumen tube to the distal tip portion. Also provided are methods for forming such multilumen tubes and incorporating such multilumen tubes into a lead body.
