Multi-suture knotless anchor for attaching tissue to bone and related method
First Claim
1. A suture anchor for knotlessly securing a soft tissue to a bone with at least one suture, wherein the suture anchor comprises a first undeployed configuration in which tissue may be drawn towards the suture anchor by applying tension to a free limb of the suture, and a second deployed configuration in which the suture anchor is fixed in the bone and the suture is locked in the suture anchor thereby securing the tissue to the bone, said suture anchor comprising:
- an anchor body having;
a distal tip with a suture tunnel disposed there-through;
a connecting portion configured to be selectively coupled to a shaft distal end of an insertion device; and
a plurality of deflecting sections extending proximally from the distal tip;
wherein an inner surface of the deflecting sections define a cavity, the cavity terminating at a distal end proximally disposed from the entire suture tunnel when both in the first undeployed and second deployed configuration; and
a sleeve member which is configured to cooperate with the anchor body so as to deflect the deflecting sections to engage bone and lock the suture in the suture anchor.

Abstract
A multi-suture knotless anchor and related method for securing soft tissue, such as tendons, to bone are described. The suture anchor includes a body, a sleeve, and an outer deformable bone locking structure. The bone locking structure has a first low profile configuration for insertion into the bone, and a second larger profile configuration for engaging the bone when actuated. The bone anchor and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.

12. A knotless suture anchoring system for anchoring a length of suture with respect to a bone, comprising:
-
an anchor insertion instrument comprising a handle, and an elongate rigid shaft extending distally from the handle, said shaft comprising a distal end section defining a threaded portion; an anchor body detachably connected to the distal end section of the elongate rigid shaft, said anchor body comprising an internally threaded portion for selectively mating with the instrument threaded portion and a distal tip, the distal tip comprising an aperture through a thickness of the distal tip; wherein the anchor body further comprises a deflectable bone anchoring structure having an inner surface defining a cavity, the cavity having a distal end proximally separated from the aperture by an intermediate portion having a solid cross-section; and a sleeve member slidably disposed on the shaft distal end section of the instrument and proximal to the anchor body, the sleeve member having an outer diameter sufficient in size and shape to radially deflect the anchoring structure. - View Dependent Claims (13, 14, 15, 16, 17, 18)
