More Information
Summary:Methods are disclosed for dissecting a mucosa and a submucosa from a muscularis propria from a region of the esophagus of a subject. These methods include injecting submucosally into the region of the esophagus of the subject a pharmaceutical composition comprising a urinary bladder extracellular matrix (ECM) hydrogel, to form a cushion between the submucosa and the underlying muscularis propria at the region of the esophagus, wherein the ECM hydrogel has the following characteristics: a) a time to 50% gelation of less than 20 minutes at a temperature of about 37° C.; b) a flow viscosity suitable for infusion into the esophagus; and c) a stiffness of about 10 to about 400 Pascal (Pa).
