Tissue augmentation material and method
View Patent ↗A material and method for augmenting soft tissue. The tissue augmentation material consists essentially of water and a polysaccharide gel former selected from the group consisting of a cellulose polysaccharide, starch, chitin, chitosan, hyaluronic acid, hydrophobe modified polysaccharide, an alginate, a carrageenan, agar, agarose, an intramolecular complex of a polysaccharide, an oligosaccharide and a macrocylic polysaccharide. Glycerin may also be included. The material may be used to augment soft tissue in a variety of areas, including the facial region and vocal folds.
1. An injectable tissue augmentation solution for augmenting soft tissue with adjusted viscosity and elasticity for a specific tissue application, consisting essentially of: (1) water; (2) glycerin; (3) an analgesic; and (4) a water soluble polysaccharide gel former consisting of a combination of sodium alginate and hyaluronic acid, whereby the augmentation solution of the water and polysaccharide gel has its viscosity and elasticity adjusted for injection into a soft tissue site.
2. A method for augmenting soft tissue, comprising the steps of:
providing a syringe including a tissue augmentation solution stored therein, the tissue augmentation solution consisting essentially of: (1) water; (2) glycerin; (3) an analgesic; and (4) a water soluble polysaccharide gel former selected from the group consisting of agar methylcellulose, hydroxypropyl methylcellulose, chitosan, sodium alginate, xanthan, hyaluronic acid and combinations thereof, whereby the augmentation solution of the water and polysaccharide gel has its viscosity and elasticity adjusted for a specific augmentation tissue application in soft tissue; and
injecting the tissue augmentation solution into a soft tissue site.
3. The tissue augmentation method of claim 2 , wherein the water soluble polysaccharide gel former is a combination of sodium alginate and hyaluronic acid.
