Abstract
A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.
Claims13
A method for implanting a prosthesis, the method comprising:
- moving a driving tube and a driving pin together for a first distance in an implantation direction,
- wherein the driving pin is disposed and longitudinally movable within the driving tube;
- pushing a driven tube and a driven pin with the driving tube and the driving pin, respectively, over the first distance,
- wherein the driven pin is disposed and longitudinally movable within the driven tube,
- wherein the driving pin and the driving tube are separate from the driven pin and the driven tube, respectively, and
- wherein the driven tube contacts a first portion of the prosthesis and the driven pin contacts a second portion of the prosthesis;
- beyond the first distance, moving the driving tube relative to the driving pin a second distance in the implantation direction;
- and
- pushing the driven tube with the driving tube over the second distance such that the driven tube and the driving tube move independently from the driven pin and the driving pin, respectively, over the second distance, and the driven tube pushes the first portion of the prosthesis as the driven tube moves over the second distance.
A method for implanting a prosthesis into tissue using a deployment device, comprising:
- actuating a driving assembly a first time such that the driving assembly engages a driven assembly on which the prosthesis is mounted,
- wherein the driving assembly comprises:
- a driving tube and
- a driving pin disposed and longitudinally movable within the driving tube,
- wherein the driven assembly comprises:
- a driven tube,
- a driven pin disposed and longitudinally movable within the driven tube, and
- a depth indicator that moves together with the driven tube,
- wherein the driving pin and the driving tube are separate from the driven pin and the driven tube, respectively, and
- wherein the driving tube and the driving pin push the driven tube and the driven pin, respectively, over a first distance;
- observing a position of the depth indicator that is associated with a depth to which the prosthesis has been implanted within the tissue;
- and
- when the position of the depth indicator is spaced apart from a predetermined depth position, actuating the driving assembly a second time such that:
- the driving tube pushes the driven tube over a second distance, and
- the driven tube and the driving tube move independently from the driven pin and the driving pin, respectively, over the second distance.
