Abstract
Methods and devices are provided for attaching soft tissue to bone. In general, a deployment device, insertion assembly, and suture anchor are provided. The insertion assembly is coupled between the deployment device and the suture anchor to allow the deployment device to deploy the suture anchor into bone. Each of the various components disclosed herein can be used alone, in combination with one another, or in combination with various other devices.
Claims22
A method for deploying a suture anchor, comprising:
- inserting into a bone tunnel a suture anchor having a generally cylindrical inner component and a tubular outer component disposed coaxially with the inner component and which outer component is coupled to a distal end of a deployment device;
- coupling suture between the inner component of the suture anchor and a suture retaining element located on a housing of the deployment device;
- and
- actuating a handle assembly to draw the outer component of the suture anchor over the inner component of the suture anchor while maintaining the inner component in a fixed position within the bone tunnel thereby locking the suture between the inner and outer components, and wherein tension applied to the suture extending between the inner component and the housing remains substantially fixed, and expanding at least a portion of the outer component to engage the bone tunnel and lock the outer component within the bone tunnel.

A method for deploying a suture anchor, comprising:
- inserting a suture anchor coupled to a distal end of a deployment device into a bone tunnel;
- tensioning a suture coupled to a tubular first component of the suture anchor;
- and
- actuating a handle assembly to slide the handle assembly relative to a housing of the deployment device, thereby mating a tubular second component of the suture anchor with the first component of the suture anchor to lock the suture between the first and second components while maintaining the position of the first component relative to the bone tunnel and maintaining substantially fixed tension in the suture, and expanding at least a portion of the second component to engage the bone tunnel.
