Implantable medical leads and methods of forming such leads are disclosed. An implantable medical lead includes a lead body, a swage base coupled to the lead body, and a polymeric member interposed at least in part between the swage base and at least one rigid component of the lead such as an electrode or annular ring. The swage base includes an annular-shaped body including a flange having a number of protrusions that extend radially outward from the flange. During a swaging process, the protrusions on the flange are compressed against the polymeric member, forming a number of channels in the member that mechanically bond the member to the swage base.

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.

An implantable lead may include a housing and a laminate distal seal disposed across a distal end of the housing. A coupler and a fixation helix secured to the coupler may be disposed within the housing. The fixation helix may have a retracted position in which the fixation helix does not penetrate the laminate distal seal and an extended position in which the fixation helix has pierced the laminate distal seal and extends therethrough.
