Knotless tissue anchor
First Claim
1. A knotless tissue anchor comprising:
- an expandable member defining a bore therethrough and including a shaft and a radially expandable portion extending distally from the shaft, the expandable portion including at least two slots defining at least two flexible legs;
an inner member slidably disposed within the bore of the expandable member such that the expandable portion expands radially outwardly in response to longitudinal motion of the expandable member relative to the inner member, the inner member including at least one fin configured and dimensioned for engagement with at least one of the at least two slots; and
a length of suture having a first end and a second end, the first end of the suture being affixed to a distal end of the inner member.

Abstract
A radially expandable knotless tissue anchor including an expandable outer member defining a bore and an inner member slidably positioned within the bore. Relative longitudinal movement of the inner member relative to the expandable member causes a portion of the expandable member to expand radially outwardly. The tissue anchor further includes a length of suture material having a first end affixed to a distal end of the inner member and a second end preferably affixed to a suturing needle. A transverse bore is provided adjacent the distal end of the inner member. There is also disclosed a method of knotlessly anchoring a section of tissue to a section of bone having a bore drilled therethrough.
