DUAL SIDE LOAD ANCHOR FOR ELECTRODE LEAD, SYSTEMS CONTAINING THE ANCHOR, AND METHODS OF MAKING AND USING

摘要

An implantable lead anchor includes a first anchor shell and a second anchor shell. The first and second anchor shells define two parallel lead channels. The lead anchor also includes an actuating mechanism to operably adjust the first and second anchor shells between a load position and a lock position. In the lock position, the first and second anchor shells are closer together than in the load position and any lead disposed within one of She two parallel lead channels is locked in place. In the load position, the first and second anchor shells are sufficiently spaced apart so that a portion of a lead can be side-loaded between the first and second anchor shells. The lead anchor also includes at least one guide element that extends between the first and second anchor shells to maintain an orientation of the first and second anchor shells relative to each other.

主权项

1. An implantable lead anchor, comprising:
a first anchor shell; a second anchor shell disposed opposite the first anchor shell, the first and second anchor shells defining two parallel lead channels between the first and second anchor shells; an actuating mechanism to operable adjust the first and second anchor shells between a load position and a lock position, wherein, in the lock position, the first and second anchor shells are closer together than in the load position and any lead disposed within one of the two parallel lead channels is locked in place and, in the load position, the first and second anchor shells are sufficiently spaced apart so that a portion of a lead can be side-loaded between the first and second anchor shells and into one of the two parallel lead channels; and at least one guide element that extends between the first and second anchor shells and is configured and arranged to maintain an orientation of the first and second anchor shells relative to each other in the lock position, in the load position, and during adjustment between the lock and load positions.
