Pre-sutured anchor for implantable leads
First Claim
1. An anchor configured to secure a therapy delivery element to a desired location of a living body, the anchor comprising:
- an anchor sleeve including;
a lumen configured to receive the therapy delivery element; and
an outer surface with a compression groove oriented generally co-axially with respect to the lumen; and
a suture material pre-tied in a self-locking compression knot extending around the compression groove, wherein, with application of a tension force to at least an end of the suture material, the suture material applies a radial compression force to compress the compression groove and compressively engage the therapy delivery element within the anchor sleeve.

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.

10. An anchor configured to secure a therapy delivery element to a desired location of a living body, the anchor comprising:
-
an anchor sleeve including; a lumen configured to receive the therapy delivery element; and an outer surface with a compression groove oriented generally co-axially with respect to the lumen; a compression member disposed within the compression groove, the compression member including; an open configuration wherein the lumen of the anchor sleeve is unconstricted by the compression member; and a compressed configuration wherein the lumen of the anchor sleeve is constricted by the compression member; and a suture material pre-tied in a self-locking compression knot extending around the compression groove, wherein, with application of a tension force to at least an end of the suture material, the suture material applies a radial compression force to place the compression member into the compressed configuration to compressively engage the therapy delivery element within the anchor sleeve. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A neurostimulation system comprising:
-
an implantable pulse generator; a therapy delivery element including; a proximal end including a contact configured to electrically couple with the implantable pulse generator; and a distal end including an electrode electrically coupled to the contact of the proximal end; an anchor configured to secure the therapy delivery element to a desired location of a living body, the anchor including; an anchor sleeve including; a lumen configured to receive the therapy delivery element; and an outer surface with a compression groove oriented generally co-axially with respect to the lumen; and a suture material pre-tied in a self-locking compression knot extending around the compression groove, wherein, with application of a tension force to at least an end of the suture material, the suture material applies a radial compression force to compress the compression groove and compressively engage the therapy delivery element within the anchor sleeve. - View Dependent Claims (18, 19, 20)
