Abstract

Polymers comprising glucosamine (GlcN) are used to make medical devices. Examples include polyGlcN and carrier molecules containing multiple GlcN residues.

Claims

exact text as granted — not AI-modified
1 . A composition comprising a biodegradable polymer comprising a plurality of glucosamine residues (GlcN). 
     
     
         2 . The composition of  claim 1 , wherein said polymer is a polyGlcN. 
     
     
         3 . The composition of  claim 1 , wherein said polymer comprises a biodegradable backbone. 
     
     
         4 . The composition of  claim 3 , wherein said backbone is a naturally occurring polymer. 
     
     
         5 . The composition of  claim 4 , wherein said naturally occurring polymer is a polypeptide. 
     
     
         6 . The composition of  claim 3 , wherein said naturally occurring polymer is a polysaccharide. 
     
     
         7 . The composition of  claim 6 , wherein said naturally occurring polysaccharide is chondroitin sulfate or hyaluronic acid. 
     
     
         8 . The composition of  claim 3 , wherein said biodegradable backbone is not a naturally occurring polymer. 
     
     
         9 . The composition of  claim 8 , wherein said non-naturally occurring polymer is polyethylene glycol or polyvinyl alcohol.
