First Claim
Patent Images
1. An apparatus for in-situ formation of a structural prosthesis, the apparatus comprising:
- a tubular member having a proximal end and an opposing distal end;
a balloon comprising a wall bounding a compartment, the balloon being coupled with the tubular member such that the tubular member communicates with the compartment of the balloon;
a curable biomaterial disposed within the compartment of the balloon; and
means for severing at least a portion of the wall of the balloon after the biomaterial has at least partially cured therein such that the balloon can be selectively removed from around the at least partially cured biomaterial.

Abstract
An apparatus for in-situ formation of a structural prosthesis includes a tubular member having a proximal end and an opposing distal end. A balloon having a compartment is disposed on the tubular member such that a curable biomaterial can be selectively delivered to the compartment of the balloon through the tubular member. A line is disposed on or in the wall of the balloon to facilitate at least partial severing of the wall of the balloon after the biomaterial has at least partially cured therein such that the balloon can be selectively removed from around the at least partially curedbiomaterial, thereby forming a structural prosthesis.

16. A method for forming a structural prosthesis within an intervertebral disc, the method comprising:
-
inserting at least a portion of a balloon within a site of an intervertebral disc;
at least partially filling the balloon within the site of the intervertebral disc with a biomaterial;
allowing the biomaterial to at least partially cure; and
removing the balloon from around the at least partially cured biomaterial within the site of the intervertebral disc. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

29. An apparatus for in-situ formation of a structural prosthesis, the apparatus comprising:
-
a balloon comprising a wall having an interior surface bounding a compartment, the balloon having a perimeter length;
a tubular member-having a passageway extending therethrough, the tubular member begin coupled with the balloon so that the passageway of the tubular member is in fluid communication with the compartment of the balloon; and
a line having a first portion continuously embedded within the wall of the balloon or continuously mounted on the interior surface of the balloon over a distance of at least half the perimeter length of the balloon. - View Dependent Claims (30, 31, 32, 33)
