Systems and methods for making and using reversible mechanical lead anchors for electrical stimulation systems
First Claim
1. A lead anchor comprising:
- a flexible housing having a first end and a second end opposite to the first end, the flexible housing defining a lead lumen forming a continuous passageway through the flexible housing, the lead lumen having a first opening defined along the first end of the flexible housing and a second opening defined along the second end of the flexible housing; and
a compressible, metal retention ring disposed within the flexible housing and around a portion of the lead lumen, the retention ring defining an uncompressed position in which the retention ring has an elongate shape, with a major axis and a minor axis, that is configured and arranged to directly engage and hold a portion of a lead, if present, received within the lead lumen, the retention ring further defining a compressed position achieved by compressing opposite ends of the major axis of the retention ring to transition the retention ring to a more circular shape that allows the lead to slidingly pass through the retention ring, wherein, upon release of the compression, the retention ring is configured and arranged to return to the uncompressed position.

Abstract
A lead anchor includes a flexible housing having a first end and a second end opposite to the first end, the flexible housing defining a lead lumen forming a continuous passageway through the flexible housing. The lead anchor also includes a compressible retention ring disposed within the flexible housing and around a portion of the lead lumen. The retention ring defines an uncompressed position in which the retention ring has an elongate shape, with a major axis and a minor axis, to hold a portion of a lead received within the lead lumen. The retention ring further defines a compressed position achieved by compressing opposite ends of the major axis of the retention ring to transition the retention ring to a more circular shape that allows the lead to slidingly pass through the retention ring. Upon release of the compression, the retention ring returns to the uncompressed position.
