A suture anchor for securing a therapy delivery element in a desired location within a living body using a suture material. The suture anchor includes an inner sleeve with a primary lumen sized to receive the therapy delivery element. The inner sleeve includes a compliant material having a first durometer. An anchor body extends around at least a portion of the inner sleeve and includes a portion of the primary lumen. The anchor body includes a compliant material having a second durometer less than the first durometer. At least one exterior suture groove is located on the anchor body to receive the suture material. The exterior suture groove extends substantially to the inner sleeve so the suture material engages directly with the inner sleeve.
