Injectable or implantable biomaterials for filling or blocking lumens and voids of the body
First Claim
1. A method for completely or partially blocking, augmenting, sealing, or filling a lumen or void within the body comprising the steps of:
- a) providing a polymer and a hydrophilic crosslinking agent in suspension or solution to form an injectable or implantable biomaterial;
b) injecting or implanting the biomaterial into a lumen or void within the body; and
c) allowing the biomaterial to anchor to body tissue surrounding the lumen or void to totally or partially block or fill the lumen or void.

Abstract
Methods for completely or partially blocking, augmenting, sealing, or filling various biological lumens and voids within the body of a patient are disclosed. Lumens include arteries, veins, intestines, Fallopian tubes, and trachea. Voids include various lesions, fissures, diverticulae, cysts, fistulae, aneurysms, or other undesirable voids that may exist within a patient'"'"'s body. In the most general method of the invention, an effective amount of a biomaterial is administered (e.g., via injection, catheter, or surgical implantation) into the lumen or void. Preferred biomaterial compositions for use in the present invention are disclosed.

46. A method for completely or partially blocking, augmenting, sealing, or filling a biological lumen or void within the body of a patient comprising administering an effective amount of a biomaterial into the lumen or void;
wherein the biomaterial is a polymeric hydrogel which comprises a first synthetic polymer crosslinked using a second synthetic polymer, wherein the first synthetic polymer contains two or more nucleophilic groups, and the second synthetic polymer contains two or more electrophilic groups capable of forming covalent bonds with the nucleophilic groups on the first synthetic polymer. - View Dependent Claims (47, 48)
