Abstract
Provided is a medical device formed entirely from or formed partially from a polymer, e.g., a polysaccharide such as chitosan. In some embodiments, the medical device may be formed as a sheet of a chitosan material. This chitosan sheet may be used to wrap around tissue, such as a nerve or tendon to help with the regeneration or healing process of the nerve or tendon, as applicable. In addition or in the alternative, the sheet may be wrapped to form a tube or other shape that can wrap around the nerve.
Claims33
A synthetic nerve guide, comprising:
- a sheet comprising a first surface and a plurality of surface structures on the first surface, wherein the plurality of surface structures are configured to selectively anchor the sheet to surrounding tissue.
A method of making a synthetic nerve guide, comprising:
- layering two or more sheets on top of one another and applying a solution to provide adhesion between the two or more sheets, wherein the synthetic nerve guide comprises 2-100 layers of sheets;
- and
- forming a plurality of surface structures on a first surface of one of the two or more sheets, wherein the plurality of surface structures are configured to selectively anchor the two or more sheets to surrounding tissue.
A synthetic nerve guide comprising:
- a sheet comprising a first surface;
- and
- a plurality of surface structures positioned on the first surface, wherein the plurality of surface structures selectively anchor the sheet to surrounding tissue.
