摘要

Provided is a flowable bioresorbable tissue dressing comprising a gas-forming porogen and a gel or gel-forming solution. Also provided is kits for preparing the above-described tissue dressing. Further provided are methods of treating a tissue site of a mammal with the above dressing. Also provided is a reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site.

主权项

1. A dressing for applying reduced-pressure treatment to a tissue site, comprising:
a gas-forming porogen comprising a particle size for developing sufficient porosity for conducting reduced pressure; a bioresorbable microsphere; and a bioresorbable gel or a bioresorbable gel-forming solution in a mixture with the gas-forming porogen and the bioresorbable microsphere; wherein the mixture is flowable, and after delivery to the tissue site, forms a scaffold comprising pores of at least 50 micrometers in diameter for delivering reduced pressure through the scaffold; and wherein the dressing is bioresorbable.
