Title:
SELF-EXPANDABLE BIOPOLYMER-MINERAL COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2012/018671
Kind Code:
A3
Abstract:
A compressed implant composite for repairing mineralized tissue. The compressed implant composite includes a matrix formed of biopolymeric fibers and a plurality of calcium- and/or silicate-based mineral particles dispersed in the matrix. The matrix constitutes 4 to 80% by weight and the mineral particles constitute 20 to 96% by weight of the composite. The composite is free of soluble collagen and is expandable to a volume 2 to 100 times of its compressed volume (e.g., upon absorption of water). Also disclosed are methods of preparing the above-described composite.
