Patent ID: 7666205

Claim:
An inflatable device for treating bone comprising a first component forming a barrier configured and adapted for insertion into bone, the barrier having a proximal end and a distal end, a longitudinal axis and inner and outer surfaces, the proximal end of the barrier being secured to a distal end of a catheter and the distal end of the barrier, upon inflation, extending away from the distal end of the catheter such that the longitudinal axis of the barrier is substantially parallel to a longitudinal axis of the catheter, the inner surface defining an enclosure having a port to receive filler material, the outer surface configured to contact and substantially conform to the surface of the bone, the barrier having an insertion configuration for placement in a bone cavity and an expanded configuration providing the enclosure to receive the filler material without releasing the filler material into the bone cavity; wherein the barrier includes at least one rupture site configured to fail under a triggering condition, such that the expanded configuration of the barrier has a first condition which contains the filler material within the enclosure and a second condition which releases the filler material from the enclosure upon failure of the at least one rupture site due to the triggering condition; wherein the at least one rupture site includes a plurality predetermined seams configured to fail under the triggering condition, the plurality of predetermined seams running parallel to the longitudinal axis of the barrier and originating from the distal end of the barrier and ending at the proximal end of the barrier, and the predetermined seams configured to fail so that, after the triggering condition has occurred, the barrier resembles an open banana peel; and wherein at least one of the plurality of predetermined seams are resorbable.
