Abstract

Claims (32)

1 . A method comprising:

inserting a compression device assembly into a patient, wherein the compression device assembly comprises:

an elongate threaded body comprising:

a threaded body first end defining a threaded body hollow interior; and

a threaded body second end comprising an opening to the threaded body hollow interior;

a sliding element defining a sliding element hollow interior and comprising a sliding element first end comprising an elongated portion; and

a nitinol compression element operatively connected to the threaded body and the sliding element, wherein:

the nitinol compression element is disposed within the threaded body hollow interior and the sliding element hollow interior; and

the nitinol compression element comprises a threaded portion for operative connection to the threaded body;

contacting the threaded body with a first bony fragment of the patient via one or more threaded body threads;

contacting the sliding element with a second bony fragment of the patient; and

applying compression to the first bony fragment and the second bony fragment via the compression element returning to a relaxed state from a deformed state.

2 . The method of claim 1 , wherein:

the compression element is cannulated;

a guidewire is further received through the cannulated compression element; and

the method further comprises guiding the compression device assembly along the guidewire to a particular location in the patient.

3 . The method of claim 2 , wherein the nitinol compression element is cannulated such that the cannulation comprises at least one of a hexalobe or polygonal shape.

4 . The method of claim 1 , wherein the compression element is in the deformed state prior inserting the compression device assembly into the patient.

5 . The method of claim 1 , wherein the compression element is in the relaxed state prior to inserting the compression device assembly into the patient.

6 . The method of claim 1 , wherein:

the compression element comprises a compression element elongated portion between a compression element first end and a compression element second end; and

the compression element first end and the compression element second end each comprise a sloped region for transitioning to the compression element elongated portion.

7 . The method of claim 1 , wherein:

the sliding element comprises one or more sliding element threads; and

a diameter of the one or more threaded body threads is less than a diameter of the one or more sliding element threads.

8 . The method of claim 1 , wherein the threaded body comprises a wall thickness equal to 0.5-4.0 mm.

9 . The method of claim 1 , wherein the threaded body comprises a wall thickness that is equal to 1.0-3.0 mm.

10 . The method of claim 1 , wherein the threaded body comprises a wall thickness that varies between 0.5-2.0 mm between the threaded body first end and the threaded body second end.

11 . The method of claim 1 , wherein the compression device assembly further comprises:

an insertion tool defining an insertion tool hollow interior and comprising one or more pins; and

one or more pin openings receiving the one or more pins.

12 . The method of claim 1 , wherein the nitinol compression element includes cross section having a solid thickness between opposing edges.
