Self-assembling peptide gel formulation and methods of use

Abstract

Compositions containing self-assembling peptides and/or self-assembling peptidomimetics ('self-assembling peptides') can be used to create a long-lasting “lift” or means of elevating tissue to be resected, dissected, manipulated or repaired, as a bulking agent, or as a tissue forming matrix by injection of a solution that forms a solid gel in situ, which is stable for a prolonged period of time from days to a month, is hemostatic, and may prevent adhesions. These self-assembling peptides and methods of use thereof enable better separation of tissues and visualization of margins, more durable and robust lifts, less need for frequent injections that carry risk of undesired perforation, and simultaneous management of adverse effects, such as bleeding, leaking, inflammation and iatrogenic injury during endoscopic, laparoscopic or other minimally invasive, or open surgical procedures in and/or on the body.
