An orthopedic fixation system includes an orthopedic implant and an implant retainer. The orthopedic implant includes a transition section deformable to move the orthopedic implant between a natural shape and an insertion shape whereby a transition of the orthopedic implant from the natural shape to the insertion shape stores deliverable energy and a transition of the orthopedic implant from the insertion shape to the natural shape delivers stored energy. The implant retainer is configured to mechanically engage the orthopedic implant across the transition section such the implant retainer constrains the orthopedic implant in the insertion shape thereby preventing a transition of the orthopedic implant from the insertion shape to the natural shape.

Method and apparatus for an orthopedic fixation system

An orthopedic fixation system includes an orthopedic implant and an implant retainer. The orthopedic implant transitions between a natural shape and an insertion shape whereby a transition of the orthopedic implant from the natural shape to the insertion shape stores deliverable energy and a transition of the orthopedic implant from the insertion shape to the natural shape delivers stored energy. The implant retainer is configured to engage the orthopedic implant and constrain the orthopedic implant in the insertion shape such that the implant grip prevents a transition of the orthopedic implant from the insertion shape to the natural shape.

Shape memory implants and methods and apparatus for the loading and implanting thereof

An orthopedic fixation system includes a sterile packaged implant kit and a sterile packaged instrument kit. The sterile packaged implant kit includes at least one surgical implant, an insertion device, and an implant package adapted to receive the at least one surgical implant and the insertion device therein. The implant package maintains the at least one surgical implant and the insertion device sterile after sterilization of the sterile packaged implant kit. The sterile packaged instrument kit includes one or more instruments necessary to use the sterile packaged implant kit and an instrument package adapted to receive the one or more instruments therein. The instrument package maintains the one or more instruments sterile after sterilization of the sterile packaged instrument kit.

An implant insertion device is adapted for use with a shape memory implant. The shape memory implant includes a bridge interconnecting first, second, and third legs. The shape memory implant is movable between a first shape in which at least the first leg is substantially non-parallel and a second shape in which at least the first leg is substantially parallel. The implant insertion device engages the shape memory implant to maintain the shape memory implant in its second shape until the delivery of the shape memory implant into tissue or bone.

Method and apparatus for loading and implanting a shape memory implant

An implant insertion device is designed for use with a shape memory implant movable between an unconstrained shape and an insertion shape. The implant insertion device maintains the shape memory implant in its insertion shape until the delivery of the shape memory implant into tissue or bone. Upon the release of the shape memory implant from the implant insertion device, the shape memory implant attempts to move from its insertion shape to its unconstrained shape, thereby releasing mechanical energy into the tissue or bone.

A drill guide includes a shaft, a drill guide assembly securable to the shaft, and a first drill guide insert. The drill guide assembly includes a first drill guide body defining a receiving passage, a locking member, and terminating in a first grasping projection that flexes between open and closed positions. The first drill guide insert installs in the receiving passage and includes a bore, a grasping projection displacement surface, a locking groove, and a key member. The grasping projection displacement surface moves the first grasping projection from its closed position to its open position during installation of the first drill guide insert. Upon installation, the locking groove receives the first grasping projection to lock the first drill guide insert in the first drill guide body, and the key member engages the locking member to prevent rotation of the first drill guide insert within the first drill guide body.

Drill guide and method of manufacture thereof

Orthopedic implant sizing device

An implant insertion system includes a shape memory implant movable between a first shape a second shape and an implant insertion device movable between an implant disengagement position and an implant engagement position. The implant insertion device receives the shape memory implant in its first shape while in its implant disengagement position. Movement of the implant insertion device from its implant disengagement position to its implant engagement position manipulates the shape memory implant from its first shape to its second shape. The implant insertion device maintains the shape memory implant in its second shape until delivery of the shape memory implant into tissue or bone.
