Abstract: Devices and methods for preparing a surgical site, and in particular vertebral members, which may include a retractable tool and an actuator. The tool may include distal and proximal members. A distal side of the distal member may be fixed in a longitudinal direction and pivotable at a point of rotation. A proximal side of the proximal member may be pivotably connected to the actuator. In a retracted position, the distal member may be pivotably connected to the proximal member longitudinally in between the point of rotation and the proximal side of the proximal member. Moving the actuator in a distal direction may push the proximal member and the distal member such that the proximal member pivots with respect to the actuator and distal member, the distal member pivots with respect to the proximal member and point of rotation, and the proximal member and distal member move laterally outward.

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.

Abstract: A prosthesis for use with a tissue repair system is capable of expanding during implantation into the tissue. The prosthesis can include a driving portion and a base portion. The driving portion helps drive the prosthesis into a tissue during a first stage of implantation. The base portion is configured to expand or splay open during a second stage of implantation. The prosthesis may include a hole for receiving a portion of a suture thread.

Abstract: A dynamic stabilization device is disclosed. The device includes a dual spring member comprising an outer spring and an inner spring that have approximately equal working lengths. The dynamic stabilization device is also configured so that the dual spring member does not undergo stresses greater than an effective fatigue limit that is related to a fatigue limit of the spring. Methods for treating a deformity of a spine using a dynamic stabilization device are also disclosed.

Abstract: A method and system of implanting multiple prostheses uses a deployment device including a front delivery assembly and a base assembly. The prostheses may be housed within the front delivery assembly and deployed using an impact force generated within the base assembly. The multiple prostheses can be implanted in quick succession. The deployment device uses power assistance generated from energy stored in an energy storage system. In one embodiment, a compression spring stores mechanical energy that can be transformed into an impacting force following a triggering event.

Abstract: An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.

Abstract: A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The deployment device also includes a driven assembly, including a driven tube and a driven pin. The driven pin and the driven tube may be further associated with the prosthesis. The driving tube, the driving pin, the driven tube and the driven pin may all be located coaxially, with the driving pin configured to translate through a cavity in the driving tube and the driven pin configured to translate through a cavity in the driven tube. This configuration allows for a two-stage implantation process for the prosthesis, as the driving tube and driving pin may move together in one stage and may move relative to one another in a second stage.

Abstract: A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The driving assembly can impact a driven assembly, which is further connected to the prosthesis. The driving assembly can impact the driven assembly multiple times, thereby driving the prosthesis further into a tissue.

Abstract: A prosthesis delivery and implantation system for tissue repair is disclosed. The implantation system includes provisions for manually applying a prosthesis to a treatment area. This system may be applied to heal any imperfections in various different types of tissue. The system also provides provisions for independently inserting two end portions of the prosthesis into tissue.

The types of prostheses which may include a selectively applied bone growth promoting agent include rods, fracture plates, screws, as well as other types of prostheses. Additionally, the structural composition of many types of prostheses may be modified to help induce bone ingrowth and allow for fusion with the implantable prosthesis.
