Abstract

This invention describes novel methods and devices for stabilizing and retracting tissue during surgery, in particular internal tissue. Patches of material, preferably biodegradable, are adhered to tissue surfaces. By manipulation of the patches, for example directly with forceps, or via sutures attached to the patches, tissues can be retracted or otherwise manipulated with minimal trauma to the tissues. The method is especially useful in minimally-invasive surgery.

Claims

AMENDED CLAIMS[received by the International Bureau on 14 October 1998 (14.10.98); original claims 1-48 replaced by amended claims 1-22 (3 pages)]
1. A kit comprising a tissue-affixing article for application to and retraction of tissue internally of a patient, and an adhesive for bonding the tissue-affixing article to the tissue.
2. The kit of claim 1 , wherein the tissue-affixing article is a patch.
3. The kit of any preceeding claim, wherein the tissue-affixing article is biodegradable.
4. The kit of any preceeding claim, wherein the adhesive is biodegradable.
5. The kit of any preceeding claim, wherein the tissue-affixing article is constructed and arranged to be applied percutaneously.
6. The kit of any preceeding claim, further comprising a suture affixed to the tissue- affixing article.
7. The kit of any preceeding claim, further comprising a retraction element associated with the tissue-affixing article.
8. The kit of claim 7, wherein a the retraction element is a tab affixed to said tissue- affixing article.
9. The kit of claim 7, wherein the retraction element is a portion of the tissue-affixing article not adherent to the tissue.
10. The kit of any preceeding claim, packaged with at least one component of the adhesive free of contact with the tissue-affixing article such that it can be applied to the tissue-affixing article during use of the tissue-affixing article.
11. The kit of claim 15, further comprising a biologically active agent in combination with the tissue-affixing article and/or the adhesive.
12. The kit of any preceeding claim, further comprising a device for the percutaneous application of the tissue-affixing article to tissue, the device comprising an obturator with a notch for holding the tissue-affixing article, and a needle or cannula for percutaneous access of the obturator.
13. The kit of claim 12, further comprising a groove in the obturator to accommodate a suture.
14. A system comprising : a tissue-affixing article for application to tissue internally of a patient; an adhesive applicable to the tissue-affixing article; and a suture fastenable to the tissue-affixing article.
15. The kit or system of any preceeding claim, wherein the tissue-affixing article is a filament, fabric, film, fleece, mesh, gauze, foam or membrane.
16. The kit or system of any preceeding claim, wherein the tissue-affixing article is constructed and arranged to be applied through a portal that passes percutaneously into the patient.
17. The kit or system of claim 16, wherein the portal is a needle.
18. The kit or system of claim 16, wherein the portal is a trocar cannula.
19. The kit or system of any preceeding claim, wherein the adhesive is photoactively adhesive to the tissue.
20. The kit or system of any preceeding claim, comprising a percutaneously-passable assembly constructed and arranged to be inserted percutaneously into a patient, the assembly including a distal portion insertable into the patient and a proximal portion designed to remain outside of the patient during a surgical procedure, the distal portion including a port designed to contain the tissue-affixing article and to carry the tissue-affixing article percutaneously into the patient and to release the article within the patient.
21. The kit or system of claim 20, further comprising an emitter of electromagnetic radiation on the distal portion of the portal.
22. The kit or system of either of claims 20 or 21 , further comprising an external grip constructed and arranged to remain outside of a patient during a surgical procedure and operatively connected to the tissue-affixing article.
