1. A suture anchor for use in attaching a first member to a second member comprising:
- a body having a first end and an opposite pointed second end and a contoured outer surface;
a reservoir formed in the body and being open at the first end of the body and closed at an opposite end that is closer to the second end, the reservoir being configured to store and release at least one of a drug, therapeutic agent, and a growth factor toward an interface between the first and second members; and

Abstract
A surgical device for use in attaching a first member (e.g., soft-tissue) to a second member (e.g., a bone) includes a suture anchor that has a body having a first end; a pointed tip at an opposite second end; and a contoured outer surface. An anchor head that is coupled to the body at the first end has an opening to permit attachment of one or more suture to the body. The suture anchor also includes a reservoir formed in the body and being open at the first end thereof and closed at an opposite end. The reservoir is configured to store and release at least one of a drug, a therapeutic agent, a growth factor, or a combination thereof from a top surface of the anchor body into a site of an interface between the first and second members to promote healing or therebetween or limit post-operative pain.

29. A method for delivering a drug, a growth factor or a therapeutic agent to a location where soft tissue contacts a bone comprising the steps of:
-
providing a suture anchor including a body having a pointed distal tip, a contoured outer surface, and an anchor head portion that includes an opening to permit attachment of one or more sutures to the body, the body having a reservoir formed therein and being open along a top surface of the anchor; disposing a drug, a therapeutic agent, a growth factor, or a combination thereof in the reservoir; and implanting the suture anchor in the bone such that the top surface faces the location where the soft tissue contacts the bone resulting in the drug, therapeutic agent, or growth factor being released from the top surface of the suture anchor and migrating in a direction toward an interface between the soft tissue and bone.
