Abstract
Systems and methods which provide a slip ring anchor configuration in which an anchor body includes inelastic members and a fluted elastomeric casing operable in cooperation to impart a radial compressive force to a corresponding lead body are described. A slip ring anchor body may comprise a plurality of inelastic members alternately disposed in flutes of a fluted elastomeric casing portion of the anchor body. The fluted elastomeric casing may form an anchor lumen through which a lead body may be inserted. Once a slip ring anchor is disposed at a desired position axially along the lead body, manipulation of one or more slip rings may be used to cause a radial compressive force to be imparted upon the lead body. A slip ring actuator tool may be used to manipulate a slip ring between unlocked and locked positions.

An anchor system for use with respect to a medical device lead, the anchor system comprising:
- an anchor body having a plurality of inelastic members and an elastomeric material forming an anchor lumen configured for insertion of a lead body therein, wherein the elastomeric material comprises a fluted elastomeric casing forming the anchor lumen, wherein inelastic members of the plurality of inelastic members are disposed within alternate flutes of the fluted elastomeric casing to provide the plurality of inelastic members in an interleaved configuration with the alternate flutes of the fluted elastomeric casing, and wherein the plurality of inelastic members and the elastomeric material are configured to cooperate to impart a radial compressive force to the lead body;
- and
- one or more slip rings configured to encircle the plurality of inelastic members and cause the radial compressive force to be imparted upon the lead body by the anchor body.
A method for affixing an anchor to a medical device lead, the method comprising:
- disposing an anchor body at a desired axial position along a body of the medical device lead, wherein the anchor body includes a plurality of inelastic members and an elastomeric material forming an anchor lumen configured for insertion of the body of the medical device lead therein, wherein the elastomeric material comprises a fluted elastomeric casing forming the anchor lumen, wherein inelastic members of the plurality of inelastic members are disposed within alternate flutes of the fluted elastomeric casing to provide the plurality of inelastic members in an interleaved configuration with the alternate flutes of the fluted elastomeric casing, and, and the plurality of inelastic members and the elastomeric material are configured to cooperate to impart a radial compressive force to the body of the medical device lead;
- and
- manipulating a slip ring encircling the anchor body to an engaged position with respect to the anchor body, wherein the slip ring is configured to cooperate with the anchor body and cause the radial compressive force to be imparted upon the body of the medical device lead by the anchor body when the slip ring is in the engaged position.
An anchor system for use with respect to a medical device lead, the anchor system comprising:
- an anchor body having a plurality of inelastic members and a fluted elastomeric casing forming an anchor lumen configured for insertion of a lead body therein, wherein inelastic members of the plurality of inelastic members are disposed within alternate flutes of the fluted elastomeric casing to provide the plurality of inelastic members in an interleaved configuration with the flutes of the fluted elastomeric casing;
- and
- one or more slip rings configured to encircle the plurality of inelastic members and the fluted elastomeric casing and cause a radial compressive force to be imparted upon the lead body by the anchor body, wherein the one or more slip rings comprise a sleeve configured to compress the fluted elastomeric casing and encourage the fluted elastomeric casing to impart the radial compressive force upon a portion of the lead body disposed in the anchor lumen when the one or more slip rings are disposed engaged positions with respect to the anchor body, and wherein the plurality of inelastic members are configured to restrict compression of the fluted elastomeric casing and control the radial compressive force to be imparted substantially equally around the portion of the lead body by the anchor body.
