Document Type and Number:
WIPO Patent Application WO/1993/010731
Kind Code:
A1
Abstract:
A method of preparing a pad to be applied to bleeding tissue comprising dissolving a resorbable reinforcing polymer in a solvent to form a solution. The solution is permitted to solidify into a desired configuration having an upper surface to form a reinforcing sheet (24). A sheet (22) of resorbable base layer material is then secured to the upper surface of the product and then allowed to dry. The base layer comprises e.g. collagen. The reinforcing means comprises material to render the pad resistant to tearing when wet.
