A tissue extender includes a ring defining a proximal end opening to engage a head of a subcutaneous screw, a first extender portion coupled to the ring at a proximal end of the first extender portion, and a second extender portion coupled to the ring at a proximal end of the second extender portion. The first extender portion includes a first coupling portion disposed at a distal end of the first extender portion, and the second extender portion includes a second coupling portion at a distal end of the second extender portion. The first and second extender portions define two side openings disposed on opposite sides of the tissue extender. The distal ends of the first and second extender portions together define a distal end opening. The first coupling portion engages the second coupling portion when the tissue extender is in an extended state. The distal end opening is larger in the extended state than in an unextended state.

Low profile bone screw extender and its application in minimum invasive spinal surgeries

The present application is directed to devices and methods for releasing tension on a surgical tether. In one embodiment, the release mechanism is constructed to be positioned between a locked position and a release position. In the locked position, the release mechanism is attached to the tether to prevent the tether from moving through the release mechanism. In the release position, the release mechanism allows the tether to move through the body. The release mechanism may be constructed to move between the release and locked positions after being implanted within a patient. In one embodiment, the release mechanism returns to the locked position after the tension on the tether has been reduced below a predetermined amount.

Devices and methods for releasing tension on a surgical tether

In one aspect, an intervertebral prosthetic device for implantation within a disc space between adjacent first and second vertebral endplates includes a body including a main body with an outer surface bearing portion configured to interface with and articulate relative to one of the first and second vertebral endplates. It also comprises an orientation protrusion shaped in a manner to at least partially inhibit rotation of the body in the disc space. The body is sized in at least one direction to fit inside a boundary defined by a travel path of the first vertebra relative to the second vertebra, the travel path forming an arc about a center of rotation of the first vertebra, the travel path being spaced from the center of rotation a distance substantially equivalent to the distance from the center of rotation to the second vertebral endplate.

Intervertebral implant and methods of implantation and manufacture

The present application is directed to tethers and methods of use. The tether is attached with anchors to bony members within the patient. The tether applies a tensile force to the bony members to reduce and/or eliminate the abnormality of the bony members. The tether includes a release mechanism with a resorbable material that initially maintains the tether in a shortened orientation. The release mechanism is eventually releases the tether to a lengthened orientation. The release mechanism may prevent the need for a subsequent surgery to release tension from the tether as the patient grows.
