First Claim
1. An interspinous process spacer system comprising:
- a light-conducting fiber configured to transmit light energy;
a liquid light-curable material; and
a catheter having an elongated shaft with a proximal end adapter, a distal end releasably engaging an expandable interspinous process spacer device, and a longitudinal axis therebetween,wherein an inner void of the catheter is sufficiently designed for passage of the liquid light-curable material to the expandable interspinous process spacer device,wherein an inner lumen of the catheter is sufficiently designed for passage of the light-conducting fiber to the expandable interspinous process spacer device,wherein the expandable interspinous process spacer device includes a circumferential groove,wherein the expandable interspinous process spacer device is sufficiently designed to inflate and deflate as the liquid light-curable material is added, andwherein the expandable interspinous process spacer device, when positioned between two spinous processes and inflated, is configured to engage the spinous processes at the groove.
