Patent ID: 7670762

Claim:
A method of preparing an absorbable remodelable graft material that is substantially hair-free and immunologically inert comprising the steps of: (a) soaking an animal tissue in a bleach solution; (b) washing the animal tissue in a detergent solution; (c) rinsing the animal tissue to remove the detergent solution; (d) configuring the animal tissue to a desired physical form and thickness; (e) soaking the animal tissue in an iodophor solution; (f) rinsing the animal tissue to remove the iodophor solution; (g) soaking the animal tissue in a hypertonic solution; (h) rinsing the animal tissue to remove the hypertonic solution; (i) agitating the animal tissue in a mixture of a caustic and peroxide solution; and (j) rinsing the animal tissue in water to remove the mixture of caustic and peroxide solution to provide the absorbable remodelable graft material that is a collagenic extra cellular matrix from which substantially all bioreactive cellular material is removed and is substantially hair-free.
