Abstract
Bioactive, hydroforming luminal liner compositions are formed of high molecular weight crystalline, absorbable copolyesters dissolved in a liquid derivative of a polyether glycol that undergoes transformation into a tissue-adhering, resilient interior cover or liner for the controlled release of its bioactive payload at clinically compromised conduits in humans as in the case of bacteria- and yeast-infected vaginal canals, esophagi, and arteries following angioplasty.
