Abstract

This invention is directed to tissue engineered prostheses made from processed tissue matrices derived from native tissues that are biocompatible with the patient or host in which they are implanted. When implanted into a mammalian host, these prostheses can serve as a functioning repair, augmentation, or replacement body part or tissue structure. There is provided a prosthesis comprising two or more superimposed, chemically bonded layers of processed tissue 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, wherein the processed tissue material is essentially acellular telopeptide collagen, about 93% by weight dry, with less than about 5% dry weight glycoproteins, glycosaminoglycans, proteoglycans, lipids, non-collagenous proteins and nucleic acids such as DNA and RNA and is substantially free of cells and cellular debris.

Claims (19)

1. A prosthesis comprising two or more superimposed, chemically bonded layers of processed tissue 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. A prosthesis comprising two or more superimposed, chemically bonded layers of processed tunica submucosa of small intestine 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.
3. The prosthesis of claim 2 wherein said prosthesis is chemically bonded with the crosslinking agent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride.
4. The method of preparing a bioremodelable prosthesis having two or more superimposed, bonded layers of processed tissue matrix, comprising:
(a) layering two or more sheets of hydrated processed tissue layers;
(b) dehydrating said tissue layers to adhere the layers together;
(c) crosslinking said tissue layers with a crosslinking agent to bond the layers together; and, (d) rinsing said layers to remove the crosslinking agent;
wherein the prosthesis, 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.
5. The method of claim 4 wherein said processed tissue matrix is derived from the tunica submucosa of the small intestine.
6. The method of claim 5 wherein the tunica submucosa is essentially acellular telopeptide collagen.
7. A method of repairing or replacing a damaged tissue comprising implanting a prosthesis in a patient 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.
8. The method of claim 7 wherein the prosthesis is a hernia repair patch, a femoral hernia repair plug, a pericardial patch, a bladder sling, a uterus sling, intra-cardiac patch, replacement heart valve, a vascular patch, an annular fibrosis repair plug, an annular fibrosis repair patch, a rotator cuff repair prosthesis, a dura mater repair patch, a cystocele repair device, a retrocele repair device, a vaginal vault prolapse repair sling, a plastic surgery implant.
9. A prosthesis comprising a single layer of processed intestinal tissue material derived from the small intestine submucosa used as a wound dressing.
10. A method for treating a damaged or diseased soft tissue in need of repair, comprising implantation of a prosthesis comprising two or more superimposed, chemically bonded layers of processed intestinal collagen derived from the tunica submucosa of small intestine which, when implanted on the damaged or diseased soft tissue, undergoes controlled biodegradation occurring with adequate living cell replacement such that the original implanted prosthesis is remodeled by the patient's living cells.
11. The method of claim 10, wherein the damaged or diseased soft tissue in need of repair is used for treating defects of the abdominal and thoracic wall, muscle flap reinforcement, rectal and vaginal prolapse, reconstruction of the pelvic floor, hernias, suture-line reinforcement and reconstructive procedures:
12. The method of claim 10, wherein the prosthesis comprises five sheets of processed intestinal collagen derived from the tunica submucosa of small intestine which are bonded and crosslinked together with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride at a concentration between 0.1 to 100 mM.
13. A wound dressing comprising a sheet of processed intestinal collagen derived from the tunica submucosa of small intestine having a thickness between about 0.05 to about 0.07 mm which is biocompatible and bioremodelable.
14. The wound dressing of claim 13, wherein the wound dressing is perforated.
15. A method for treating a wound comprising applying a wound dressing construct comprising a sheet of processed intestinal collagen derived from the tunica submucosa of small intestine having a thickness between about 0.05 to about 0.07 mm which is biocompatible and bioremodelable, to a wound to treat the wound.
16. The method of claim 15, wherein the wound is selected from the group consisting of: partial and full thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds, donor site wounds for autografts, post-Moh's surgery wounds, post-laser surgery wounds, wound dehiscence, trauma wounds, abrasions, lacerations, second-degree burns, skin tears and draining wounds
17. A method for treating a hypermobile organ comprising implanting a surgical sling device comprising three to five layers of processed intestinal collagen derived from the tunica submucosa of small intestine which is bonded and crosslinked together with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride at a concentration between 0.1 to 100 mM.
18. A surgical sling device for supporting hypermobile organs comprising three to five layers of processed intestinal collagen derived from the tunica submucosa of small intestine which is bonded and crosslinked together with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride at a concentration between 0.1 to 100 mM.
19. The surgical sling device of claim 18, wherein the surgical sling is used for pubourethral support, prolapse repair (urethral, vaginal, rectal and colon), reconstruction of the pelvic floor, bladder support, sacrocolposuspension, reconstructive procedures and tissue repair.
