Fixation arrangements for implantable leads and methods of making and using

摘要

An implantable member has a body with a distal end portion and either a fixation portion of the body disposed near the distal end portion or a fixation device attached to a tip of the distal end portion of the body. The fixation portion can include at least one surface feature of the body that facilitates fixation of the implantable member within tissue when implanted.
