Abstract
The present invention discloses a technique for forming a hardened orthopaedic paste in a bone cavity, which involves a forced-feeding balloon rupture mechanism. This mechanism includes continuously or intermittently injecting a liquid or gas into a perforated balloon containing a hardened orthopaedic paste therein in a bone cavity until the perforated balloon is dilated to exceed a critical size, and thus ruptures.
Claims23
A perforated balloon for forming a hardened an orthopaedic paste in a bone comprising a neck adapted to be mounted on an end of a tube through which an orthopaedic paste is injected into the perforated balloon;
- and leaking perforations, wherein said leaking perforations have a size which is penetrable to liquid contained in said orthopaedic paste but substantially impenetrable to powder contained in said orthopaedic paste under an expanded condition of said perforated balloon, in which the improvement comprises a rupture array formed on said perforated balloon for initiating a rupture of said perforated balloon when the perforated balloon is dilated to exceed a critical size.
A method for forming a hardened orthopaedic paste in a bone comprising continuously or intermittently injecting a liquid or gas into a perforated balloon containing a hardened orthopaedic paste therein in a bone cavity until the perforated balloon is dilated to exceed a critical size, and thus ruptures.
