Estimating the term…
Cross-linked hydrogels comprise a variety of biologic and non-biologic polymers, such as proteins, polysaccharides, and synthetic polymers. Such hydrogels preferably have no free aqueous phase and may be applied to target sites in a patient's body by extruding the hydrogel through an orifice at the target site. Alternatively, the hydrogels may be mechanically disrupted and used in implantable articles, such as breast implants. When used in vivo, the compositions are useful for controlled release drug delivery, for inhibiting post-surgical spinal and other tissue adhesions, for filling tissue divots, tissue tracts, body cavities, surgical defects, and the like.
A fragmented biocompatible hydrogel which is at least partially hydrated and is substantially free from an aqueous phase, wherein said hydrogel comprises gelatin and will absorb water when delivered to a moist tissue target site and, wherein the gel has a subunit size in the range from 0.01 mm to 5 mm when fully hydrated and an equilibrium swell from 400% to 5000%, said hydrogel being present in an applicator.
