Abstract

This invention is directed to prosthesis, which, when implanted into a mammalian patient, serves as a functioning replacement for a body part, or tissue structure, and will undergo controlled biodegradation occurring concomitantly with bioremodeling by the patient's living cells. The prosthesis is treated so that it is rendered non-antigenic so as not to elicit a significant humoral immune response. The prosthesis of this invention, in its various embodiments, thus has dual properties. First, it functions as a substitute body part, and second, it functions as bioremodeling template for the ingrowth of host cells.

Claims (7)

1. A prosthesis comprising two or more superimposed, bonded layers of collagen material which, when implanted into a mammalian patient, undergoes controlled biodegradation occurring with adequate living cell replacement such that the original implanted prosthesis is remodeled by the patient's living cells.
2. The prosthesis of claim 1 wherein the shape of said prosthesis is flat, tubular, or complex.
3. The prosthesis of claim 1 wherein said collagen material is from a mammalian source and is intestinal material, fascia lata, dura mater, and pericardium.
4. The prosthesis of claim 3 wherein said collagen material is the tunica submucosa of the small intestine.
5. The prosthesis of claim 1 wherein said collagen layers are bonded together byheat welding for a time and under conditions sufficient to effect the bonding of the collagen layers.
6. The prosthesis of claim 1 wherein said prosthesis is crosslinked with a crosslinking agent.
7. The prosthesis of claim 6 wherein said prosthesis is crosslinked with the crosslinking agent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride.8. The prosthesis of claim 6 wherein sulfo-N-hydroxysuccinimide is added to the crosslinking agent.
9. The prosthesis of claim 6 wherein acetone is added to the crosslinking agent.10. The prosthesis of claim 1 wherein the prosthesis is sterilized with peracetic acid.
11. The prosthesis of claim 10 wherein said prosthesis is non-antigenic.
12. The prosthesis of claim 1 wherein one or more surfaces of said prosthesis iscoated with a collagenous material which acts as a smooth flow surface.
13. The prosthesis of claim 1 wherein said prosthesis further contains pores.

14. The prosthesis of claim 1 wherein said prosthesis is further composed of chopped collagen fibers.
15. The prosthesis of claim 1 wherein said prosthesis is further composed of collagen threads.

(a) disinfecting the collagen material with an agent that retains the bioremodelable properties of said material; and, (b) crosslinking said disinfected collagen material with a crosslinking agent;
wherein said thus formed prosthesis when implanted into a mammalian patient, undergoes controlled bioremodeling occurring with adequate living cell replacement such that the original implanted prosthesis is remodeled by the patient's living cells without eliciting a significant humoral immune response.
33. The method of claim 32 wherein said mammalian source is selected from the group consisting of intestinal material, fascia lata, dura mater, and pericardium.
34. The method of claim 33 wherein said collagen material is the tunica submucosa of the small intestine.
