Abstract

An orthopedic implant that comprises a spacer portion having a superior portion and an inferior portion, and a staple portion. The staple portion is integral with the spacer portion and comprises a crown portion and first and second leg portions, the first and second leg portions having distal ends that converge from the crown portion and that are composed of a material that has superelastic properties at body temperatures, whereby the first and second leg portions are configured to impart a compressive biasing force when the implant is installed with the legs under tension.

First claim

What is claimed is:

1. An orthopedic implant kit, comprising:
an orthopedic implant comprising:
a first staple portion formed of a metal material that has superelastic properties at body temperatures, the first staple portion comprising first leg portions that converge from a first crown portion;
a second staple portion formed of a metal material that has superelastic properties at body temperatures, the second staple portion comprising second leg portions that converge from a second crown portion; and
a spacer portion positioned between and connected to the first crown portion and the second crown portion, the spacer portion extending beyond the first and second crown portions generally towards respective distal ends of the first and second leg portions; and

an insertion tool configured to releasably hold the orthopedic implant and apply and maintain a tension in the first leg portions and the second leg portions relative to a resting state thereof during installation of the orthopedic implant, wherein a lateral dimension of a superior portion of the spacer portion is greater than a lateral dimension of an inferior portion of the spacer portion such that the spacer portion is wedge-shaped.

2. An orthopedic implant kit, comprising:
an orthopedic implant comprising:
a first staple portion formed of a metal material that has superelastic properties at body temperatures, the first staple portion comprising first leg portions that converge from a first crown portion;
a second staple portion formed of a metal material that has superelastic properties at body temperatures, the second staple portion comprising second leg portions that converge from a second crown portion; and
a spacer portion positioned between and connected to the first crown portion and the second crown portion, the spacer portion extending beyond the first and second crown portions generally towards respective distal ends of the first and second leg portions; and

an insertion tool configured to releasably hold the orthopedic implant and apply and maintain a tension in the first leg portions and the second leg portions relative to a resting state thereof during installation of the orthopedic implant, wherein the spacer portion has a tapered wedge-shaped profile.

3. An orthopedic implant kit, comprising:
an orthopedic implant comprising:
a first staple portion formed of a metal material that has superelastic properties at body temperatures, the first staple portion comprising first leg portions that converge from a first crown portion;
a second staple portion formed of a metal material that has superelastic properties at body temperatures, the second staple portion comprising second leg portions that converge from a second crown portion; and
a spacer portion positioned between and connected to the first crown portion and the second crown portion, the spacer portion extending beyond the first and second crown portions generally towards respective distal ends of the first and second leg portions; and

an insertion tool configured to releasably hold the orthopedic implant and apply and maintain a tension in the first leg portions and the second leg portions relative to a resting state thereof during installation of the orthopedic implant, further comprising a drilling template for positioning pilot shafts in the bone of a patient.

4. The orthopedic implant kit of claim 3 , wherein the drilling template comprises first and second pilots for positioning pilot holes that accommodate the pilot shafts, the first and second pilots being spaced apart at a same distance as a spacing between the respective distal ends of the first and second leg portions when the tension is applied thereto by the insertion tool.

5. The orthopedic implant kit of claim 3 , further comprising a spacer to assist in placement of the drilling template on the patient.
