Abstract
An implant material in the form of a natural animal tissue crosslinked into a pre-formed shape, the tissue being adapted to substantially retain its shape when implanted into a body. Suitable tissues include fibro-serous membranes such as pericardium. Suitable crosslinking agents include aldehydes (e.g., glutaraldehyde), epoxides, isocyanates, carbodiimides, isothiocyanates, glycidalethers, and acyl azides. The implant material can be processed in either the supple or non-supple form, by the judicious use of ethanol and/or other dehydrating solutions in the course of its processing.
Claims27
An implant material comprising a natural animal tissue crosslinked in position upon a form or mandrel into a pre-formed shape of the form or mandrel, the tissue substantially retaining said shape when implanted into a body.
A process for preparing an implant material, comprising the steps of forming a natural tissue into a preformed shape upon a form or mandrel and crosslinking the formed tissue in order to retain the shape of the form or mandrel, the tissue substantially retaining said shape when removed from the form or mandrel and/or when implanted into a body.
