Bone structure coupling systems and methods of use

Bone structure coupling devices and methods are provided herein. An example method includes positioning a tubular retraction guide body into a patient, the tubular retraction guide body having two prongs that are positioned in a joint between two adjacent bone structures, creating a hemispherical groove on each of the two adjacent bone structures using a drill bit passed through the tubular retraction guide body, incising out the hemispherical grooves with a broach passed through the tubular retraction guide body, and inserting a graft body having a generally rectangular cross sectional area into the angular grooves to couple the two adjacent bone structures together.

ENCASED MAGNETIC BONE GROWTH STIMULATING DEVICES AND METHODS OF USE

Encased magnetic bone growth stimulating devices and methods of use are provided herein. An example device includes a magnet and a biocompatible means for enclosing the magnet. The biocompatible means for enclosing the magnet further comprises a means for releasably coupling with the medical implant and a means for coupling the enclosing means to an implantable medical device. 1. A device , comprising: [ 'a tubular sidewall that is enclosed on a second end thereof to form an enclosure cavity; and', 'a first portion having, 'a second portion that is a cap that is joined to a first end of the first portion, wherein first portion and second portion are hermetically sealed to one another; and, 'an enclosure comprisinga rare-earth magnet disposed within the enclosure cavity.2. The device according to claim 1 , wherein the first end of the first portion comprises a flange that mates with the second portion of the enclosure.3. The device according to claim 1 , further comprising a rod coupling assembly comprising:a body portion having a body portion cavity that receives the enclosure having the rare-earth magnet hermetically sealed inside; anda coupling hook that releasably attaches to a rod of a spinal implant construct.4. The device according to claim 3 , wherein the body portion further comprises a cover plate that seals the body portion cavity.5. The device according to claim 3 , wherein the body portion further comprises a locking member disposed between the body portion cavity and the coupling hook claim 3 , the locking member preventing removal of the rod coupling assembly from the rod when the locking member is installed.6. The device according to claim 3 , wherein the body portion cavity is oriented in parallel with a central axis of the rod.7. The device according to claim 3 , wherein the body portion cavity is oriented in such a way that the rare-earth magnet within the enclosure has at least one magnetic pole that is oriented in a direction of desired bone ...
