Spinal fill for disk surgery
First Claim
1. A procedure for surgically treating spinal disease of a patient, the disease being associated with a particular site at the patient'"'"'s spine, comprising the steps:
- (i) providing access to the site at the patient'"'"'s spine associated with the disease, (ii) applying a flowable polymerizable material to the site at the patient'"'"'s spine associated with the disease to treat the disease when hardened, the flowable material comprising an adhesive or spinal fill material consisting essentially of a mixture of polymerizable materials that upon in situ curing forms a hardened polyisobutylmethacrylate.

Abstract
The invention is based on the use of polyisobutylmethacrylate instead of PMMA as an adhesive or spinal fill material for treating diseases of the spine. Polyisobutylmethacrylate has several advantages over PMMA, mainly less heat is developed during the in situ polymerization process. When using any spinal adhesive of fill material that is light activated, a tube can be used to transmit activating light to the light-activated adhesive or spinal polymerizable fill material at the surgical site. In addition, a mesh bag comprising optical fibers or similar light transmitting material can be employed to receive the injected light-activated fill, with the mesh bag, irradiated externally, for directing the light via the bag to the polymerizable fill.

8. A surgical instrument for surgically treating spinal disease of a patient, comprising:
(a) an elongated tubular body having first proximal and second distal ends and being sufficiently long for the distal end to reach the site of the spinal disease while the proximal end is still outside the patient, the tubular body having the capability of transmitting UV radiation, such that when UV radiation is caused to enter the tubular body at its proximal end the radiation will be transmitted to and exit from the distal end. - View Dependent Claims (9, 10, 11)
