Anchor for implantable medical device
First Claim
1. An anchor for a therapy delivery element having an outer surface about which the anchor is disposable, the anchor comprising:
- a body portion having elastomeric properties comprising a first opening, a second opening, and a non-linear lumen extending though the body portion from the first opening to the second opening in a relaxed state, and a linear lumen in a stretched state, wherein the linear lumen of the body portion is adapted to receive the therapy delivery element in the stretch state, and the non-linear lumen of the body portion frictionally engages the outer surface of the therapy delivery element in the relaxed state.

Abstract
An anchor for an implantable medical device, anchor delivery tools, kits, and methods, all directed to securing a therapy delivery element at a target location in a patient. An anchor for a therapy delivery element having an outer surface about which the anchor is disposable. The anchor includes a body portion having elastomeric properties, a first opening, a second opening, and a non-linear lumen extending though the body portion from the first opening to the second opening in a relaxed state. The non-linear lumen becomes a linear lumen in a stretched state. The linear lumen of the body portion is adapted to receive the therapy delivery element and the non-linear lumen frictionally engages the outer surface of the therapy delivery element in the relaxed state.

12. A kit comprising:
-
a first anchor comprising a body portion having elastomeric properties, the body portion comprising a first opening, a second opening, and a first non-linear lumen extending though the body portion from the first opening to the second opening in a relaxed state, and a first linear lumen in a stretched state, wherein the first linear lumen of the body portion is adapted to receive a therapy delivery element and the first non-linear lumen of the body portion frictionally engages an outer surface of the therapy delivery in the relaxed state; a second anchor comprising a body portion having elastomeric properties, the body portion comprising a first opening, a second opening, and a second non-linear lumen extending though the body portion from the first opening to the second opening in a relaxed state, and a second linear lumen in a stretched state, wherein the second linear lumen of the body portion is adapted to receive the therapy delivery element and the second non-linear lumen of the body portion frictionally engages the outer surface of the therapy delivery in the relaxed state, wherein the first non-linear lumen comprises a configuration different than the second non-linear lumen; a therapy delivery element having an outer surface about which the body portion of the first or second anchors is disposable; and an anchor delivery tool comprising an anchor delivery tube with a delivery lumen adapted to receive the therapy delivery element, and an outer surface with a cross-sectional area greater than a cross-sectional area of the first and second linear lumens of the body portions in the stretch state, such that the body portions compressively engage the delivery tube.

13. A method of delivering an anchor for an implantable medical device in a patient, the method comprising the steps of:
-
stretching an elastomeric body portion of an anchor to convert a relaxed non-linear lumen to a stretched linear lumen; inserting an anchor delivery tube into the linear lumen, the linear lumen having a cross-sectional area less than a cross-sectional area of the delivery tube, such that the body portion compressively engages the delivery tube in a stretched state; inserting a therapy delivery element into a lumen in the anchor delivery tube; positioning the anchor delivery tube relative to the therapy delivery element where the anchor is to be located; retracting the anchor delivery tube into an anchor delivery tool so that the anchor resumes a relaxed state and the non-linear lumen of the body portion frictionally engages the outer surface of the therapy delivery in the relaxed state; suturing the anchor to the patient; and removing the anchor delivery tube from the therapy delivery element. - View Dependent Claims (14, 15)

16. A method of implanting a neurostimulation system within a living body, the method comprising the steps of:
-
implanting an implantable pulse generator within the living body; positioning electrodes at a distal end of a therapy delivery element at a target location within the living body; stretching a non-linear lumen extending through an elastomeric body portion of an anchor to insert an anchor delivery tube, the non-linear lumen having a cross-sectional area less than a cross-sectional area of the delivery tube, such that the body portion compressively engages the delivery tube in a stretched state; inserting a therapy delivery element into a lumen in the anchor delivery tube; positioning the anchor delivery tube relative to the therapy delivery element where the anchor is to be located; retracting the anchor delivery tube into an anchor delivery tool so that the anchor resumes a relaxed state and the non-linear lumen of the body portion frictionally engages the outer surface of the therapy delivery in the relaxed state; suturing the anchor to the patient; and removing the anchor delivery tube from the therapy delivery element; and electrically coupling the proximal end of the therapy delivery element to the implantable pulse generator.
