Abstract
Methods and devices are provided for securing suture to tissue. In one exemplary embodiment, the implant can include an intermediate portion, a first radially expandable portion extending from the intermediate portion, and a second radially expandable portion extending from the intermediate portion. The implant can be configured to be inserted through a delivery device in a first configuration and deployed into a hole formed in tissue in a second configuration such that the intermediate portion is positioned within the hole. A suture can be inserted through a passageway of the intermediate portion positioned within the hole, and the suture can be tensioned to secure the tissue to bone.
Claims19
A surgical method, comprising:
- advancing an implant in a first configuration through a cannula, the implant having an intermediate portion with a first radially expanding portion extending distally therefrom and a second radially expanding portion extending proximally therefrom;
- advancing the implant distally out of the cannula to position the implant within an opening formed in soft tissue, the implant moving from the first configuration to a second radially expanded configuration such that the first radially expanding portion of the implant is positioned on a distal side of the opening, the second radially expanding portion of the implant is positioned on a proximal side of the opening, and the intermediate portion is positioned within the opening;
- advancing a suture through the intermediate portion positioned in the soft tissue;
- advancing an anchor into a bone;
- and
- securing the tissue in position relative to the bone, the suture advanced through the intermediate portion being coupled to the bone to facilitate the securing.
A surgical method, comprising:
- advancing an introducer device at least partially through an opening formed in tissue, the introducer device having an implant disposed in an inner passageway thereof;
- moving a first radially expanding portion of the implant out of the inner passageway, thereby causing the first radially expanding portion to be positioned on a distal side of the opening, the first radially expanding portion expanding into contact with a distal surface of the tissue;
- moving a second radially expanding portion of the implant out of the inner passageway to position the second radially expanding portion on a proximal side of the opening, the second radially expanding portion expanding into contact with a proximal surface of the tissue, and a hollow intermediate portion of the implant extending between the first radially expanding portion and the second radially expanding portion being positioned within the opening, the hollow intermediate portion having a continuous inner wall;
- advancing a suture through the hollow intermediate portion positioned within the opening;
- advancing an anchor into a bone;
- and
- securing the tissue in position relative to the bone, the suture advanced through the intermediate portion being coupled to the bone anchor to facilitate the securing.
