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.
Claims30
A tissue repair membrane comprising:
- a tissue repair membrane substrate;
- a first coating applied to at least a portion of a surface of the tissue repair membrane substrate, wherein the first coating comprises a first hydrogel polymer formed from a solution of hyaluronic acid and alginate, wherein the first hydrogel polymer has a net negative charge;
- and
- a second coating applied on the first coating, wherein the second coating comprises a second hydrogel polymer formed from a solution of hyaluronic acid without alginate, wherein the second hydrogel polymer has a net negative charge,
- wherein at least one of the first coating or the second coating provides one or more of self-adhesion and lubrication to the tissue repair membrane when in a hydrated condition.
