Abstract
Provided herein is a tissue repair matrix modified with a hydrogel polymer to provide adhesion and/or lubrication to assist with the use and implantation of the tissue repair membrane, and to facilitate healing and/or avoid or minimize damage to adjacent, e.g., tissues, during or after implantation.
Claims29
A tissue repair membrane comprising:
- a tissue repair membrane substrate formed of a multi-layer sheet;
- and
- a hydrogel polymer coating on the tissue repair membrane substrate, wherein the hydrogel polymer coating is formed from a solution of hyaluronic acid and alginate, a concentration of each of the hyaluronic acid and the alginate being 0.5% to 5% by weight.
A tissue repair membrane comprising:
- a tissue repair membrane substrate formed of a multi-layer sheet, wherein the multi-layer sheet comprises two to six layers of animal or human tissue;
- and
- a hydrogel polymer coating on the tissue repair membrane substrate, wherein the hydrogel polymer coating is formed from a solution of at least one of hyaluronic acid having a concentration of 0.5% to 5% by weight, or alginate having a concentration of 0.5% to 5% by weight.
