Abstract: An implantable lead system may include an adjustable lead assembly. The lead assembly may include a fixation member and an implantable lead slidably coupled to and rotatable relative to the fixation member. The implantable lead system may include a telescoping delivery system. The delivery system may include an outer catheter and an inner catheter slidably coupled to and rotatable relative to the outer catheter. The lead assembly may be implanted in a cardiac septal wall through the delivery assembly.

Abstract: A relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.
