Pre-sutured anchor for implantable leads
First Claim
1. An anchor for securing a therapy delivery element to a desired location within a living body, the anchor comprising:
- a deformable anchor sleeve comprising a lumen sized to receive the therapy delivery element, and an outer surface with one or more annular compression grooves oriented generally co-axial to the lumen;
at least one compression member located in a compression groove in an open configuration, the compression member comprising at least one stop; and
a suture material pre-tied in a self-locking compression knot extending around each compression member, the suture material comprising distal ends adapted to receive a tension force that is transmitted as a radial compression force to deform the compression members to engage the stop in a compressed configuration, the anchor sleeve compressively engaging the therapy delivery element in the compressed configuration.

Abstract
A pre-sutured anchor including a deformable anchor sleeve with a lumen sized to receive the therapy delivery element. An outer surface of the anchor sleeve including one or more annular compression grooves oriented generally co-axial to the lumen. At least one compression member is located in a compression groove in an open configuration. The compression member includes at least one stop. A suture material pre-tied in a self-locking compression knot extends around each compression member. The suture material includes distal ends adapted to receive a tension force that is transmitted as a radial compression force to deform the compression members and substantially engage the stop in a compressed configuration. The anchor sleeve compressively engages the therapy delivery element in the compressed configuration.
