Abstract
A vacuum bag method for in-situ molding of surgical implants. The method comprises creating an implant precursor material composed of an aggregation of polymer beads coated with a hydrophilic monomer dispersion. A flexible bag containing the implant precursor is molded in-situ to a desired specific shape, and the implant precursor is then rigidified by applying a vacuum to the interior of the bag. The implant precursor is cured by heating to form a unitary porous prosthesis which may be implanted into body tissue to remedy bone defects.
