1. A lead anchor, comprising:
- a body defining at least one first portion of a lead lumen, the body having a first opening and a second opening;
an obstructing member disposed within the body, wherein the entire obstructing member is translatable from a first position to a second position, the obstructing member defining a second portion of the lead lumen;
a spring disposed in the body and configured and arranged to operate on the obstructing member so that the second portion of the lead lumen is coterminous with the at least one first portion of the lead lumen and forms a continuous lead path when the spring is compressed as the obstructing member is translated to the first position and the second portion of the lead lumen is offset from the at least one first portion of the lead lumen when the spring is not compressed and the obstructing member is in the second position, wherein the spring is disposed between the first opening and the second opening so that the lead path passes longitudinally through the spring.

Abstract
A lead anchor includes a body defining at least one first portion of a lead lumen, the body having a first opening and a second opening. An obstructing member is disposed within the body. The obstructing member defines a second portion of the lead lumen. A spring is disposed in the body and configured and arranged to operate on the obstructing member so that the second portion of the lead lumen is coterminous with the at least one first portion of the lead lumen and forms a continuous lead path when the spring is compressed and the second portion of the lead lumen is offset from the at least one first portion of the lead lumen when the spring is not compressed.

17. A method of implanting an implantable stimulation device, the method comprising;
-
implanting a portion of a lead having an electrode array near tissue to be stimulated; applying a force to an obstructing member of a lead anchor to translate the entire obstructing member to a first position, the lead anchor comprising a body defining at least one first portion of a lead lumen, the body having a first opening and a second opening, the obstructing member defining a second portion of the lead lumen, a spring disposed in the body and configured and arranged to operate on the obstructing member so that the second portion of the lead lumen is coterminous with the at least one first portion of the lead lumen and forms a continuous lead path when the spring is compressed with the obstructing member translated to the first portion and the second portion of the lead lumen is offset from the at least one first portion of the lead lumen when the spring is not compressed and the obstructing member is in a second position wherein the spring is disposed between the first opening and the second opening so that the lead path passes longitudinally through the spring; placing a lead through the lead path; releasing the force on the obstructing member to translate the obstructing member to the second position so that the lead path locks a portion of the lead with the lead anchor; securing the lead anchor to the surrounding tissue using sutures. - View Dependent Claims (18, 19)
