SPINAL IMPLANT CONFIGURED TO APPLY RADIATION TREATMENT AND METHOD
First Claim
Patent Images
1. A vertebral implant for replacing at least an anterior portion of a central vertebra and at least portions of two spinal discs, wherein the at least anterior portion of the central vertebra is removed from between a first vertebra and a second vertebra, the vertebral implant comprising:
- a strut having a first end and an opposite second end; and
a first cap coupled to the first end of the strut, the first cap comprising;
a proximal end coupled to the first end of the strut,a distal end configured to engage with the first vertebra,a first wall extending between the proximal end of the first cap and the distal end of the first cap, wherein the first wall includes materials that substantially block the transmission of radiation through the first wall, anda first floor extending from the first wall, wherein the first floor and the first wall form a cavity near the distal end of the first cap;
wherein the vertebral implant is adapted to contact the first vertebra and the second vertebra and provide support between the first vertebra and the second vertebra.

20. A means for applying radiation to a vertebral body comprising:
-
a spacing means for providing support between two vertebral bodies; and a radiation emitting device coupled to the spacing means; wherein the spacing means includes a radiation containment means that is capable of blocking transmission of radiation from the radiation emitting device in one or more directions and permitting transmission of radiation from the radiation emitting device in one or more directions.

21. A method of irradiating cells of a treatable vertebral body in a spinal column comprising:
-
removing a central vertebral body that is adjacent to the treatable vertebral body; providing a vertebral body replacement implant with a cavity, wherein the vertebral body replacement implant substantially blocks the transmission of radiation in all directions except the direction toward the treatable vertebral body when the vertebral body replacement implant is implanted; inserting a radiation emitting device in the cavity in the vertebral body replacement implant; and implanting the vertebral body replacement implant in a spinal column. - View Dependent Claims (22)
