Abstract

A surgical tool includes a shaft for receiving implants. The shaft defines a non-linear track. The tool includes a deployment member movable along the track to deploy the implants. An implant includes a body, and a plurality of alternating threads and flutes helically arranged about the body such that the body rotates under a linear applied force. Alternatively, an implant includes a body having a distal end for pound-in advancement into tissue. The body includes a plurality of cone-shaped, stacked barbs. A surgical tool includes two implants. The first implant has forward threads and the second implant has reverse threads. The first implant has threads for rotary advancement into tissue and the second implant is configured for pound-in advancement into tissue. The first and second implants are configured for pound-in advancement into tissue.

First claim

What is claimed is:

1. A surgical tool comprising:
an outer tubular member, an adaptor coupled to the outer tubular member, and a handle coupled to the adapter, the adaptor having a non-circumferential, continuous guide track formed along a length of the adaptor, the handle having a nub disposed within the guide track, the adaptor disposed within an opening of the actuator handle such that the opening completely encircles a portion of the adaptor;
a first implant and a second implant housed within the outer tubular member, the second implant proximal to the first implant; and
a deployment element coupled to the handle and received within the outer tubular member for advancement of the first and second implants into tissue,
wherein a partial advancement of the nub along the guide track by the handle deploys the first implant from the outer tubular member and another partial advancement of the nub along the guide track by the handle deploys the second implant from the outer tubular member.

2. The surgical tool of claim 1 further comprising a suture joining the first and second implants.

3. The surgical tool of claim 1 , wherein the nub is disposed within the opening of the handle.

4. A surgical tool comprising:
an outer tubular member, an adaptor coupled to the outer tubular member, and a handle coupled to the adaptor, the adaptor including a non-circumferential, continuous guide track formed along a length of the adaptor, the handle having a nub disposed within the guide track, the adaptor disposed within an opening of the handle such that the opening completely encircles a portion of the adaptor;
a first implant coupled to the outer tubular member for deployment at a first surgical site;
a second implant coupled to the outer tubular member and located proximal to the first member, for deployment at a second surgical site spaced from the first surgical site; and
a deployment element coupled to the handle and received within the outer tubular member for advancement of the first and second implants into tissue,
wherein a partial advancement of the nub along the guide track by the handle deploys the first implant from the outer tubular member and another partial advancement of the nub along the guide track by the handle deploys the second implants from the outer tubular member.

5. The surgical tool of claim 4 further comprising a suture joining the first and second implants.

6. A surgical tool comprising:
an outer tubular member, an adaptor coupled to the outer tubular member, and a handle coupled to the adaptor, the adaptor including a non-circumferential, continuous guide track formed along a length of the adaptor, the handle having a nub disposed within the guide track;
a first implant coupled to the outer tubular member for deployment at a first surgical site;
a second implant coupled to the outer tubular member and located proximal to the first member, for deployment at a second surgical site spaced from the first surgical site; and
a deployment element coupled to the handle and received within the outer tubular member for advancement of the first and second implants into tissue,
wherein the adaptor is disposed within a circular opening of the handle completely encircling a portion of the adaptor.

7. The surgical tool of claim 6 , wherein the nub is disposed within an opening of the handle.

8. A surgical tool comprising:
an outer tubular member, an adaptor coupled to the outer tubular member, and a handle coupled to the adaptor, the adaptor including a non-circumferential, continuous guide track formed along a length of the adaptor, the handle having a nub disposed within the guide track;
a first implant and a second implant housed within the outer tubular member, the second implant proximal to the first implant; and
a deployment element coupled to the handle and received within the outer tubular member for advancement for the first and second implants into tissue,
wherein the adaptor is disposed within a circular opening of the handle, the handle completely encircling a portion of the adaptor.

9. A surgical tool comprising:
an outer tubular member, an adaptor coupled to the outer tubular member, and a handle coupled to the adaptor, the adaptor including a non-circumferential, continuous guide track formed along a length of the adaptor, the handle having a nub disposed within the guide track, the adaptor disposed within an opening of the handle such that the opening completely encircles a portion of the adaptor;
a first implant and a second implant housed within the outer tubular member, the second implant proximal to the first implant; and
a deployment element coupled to the handle and received within the adaptor and the outer tubular member for advancement of the first and second implants into tissue,
wherein a partial advancement of the nub along the guide track by the handle deploys the first implant from the outer tubular member and another partial advancement of the nub along the guide track by the handle deploys the second implants from the outer tubular member.

10. The surgical tool of claim 9 , wherein the nub is disposed within the opening of the handle.
