Abstract

A method for treating a wound or defect at a surgical target site using a minimally invasive surgical procedure is provided which includes utilizing a surgical access device such as a port or a catheter having a plurality of reactive members of a specific binding pair releasably contained on a surface of the access device, the reactive members having affinity for binding a cellular component of tissue cells located at the target site; contacting the surface of the access device with the tissue cells, wherein upon contact of the reactive members on the surface of the access device with the tissue cells, the reactive members are released from the surface of the access device and bind to the tissue; providing a tissue repair member having secured thereto a plurality of complementary reactive members of the specific binding pair; and applying the tissue repair member to the tissue, wherein upon contact of the complementary reactive members on the surface of the tissue repair member with the reactive members on the tissue, covalent bonds are formed between the reactive members and the complementary reactive members, thus bonding the tissue repair member to the tissue. A surgical access device for use in minimally invasive surgery is provided which includes a plurality of reactive members of a specific binding pair releasably contained on a surface of the access device, the reactive members having an affinity for binding a cellular component of tissue cells and another affinity for binding complementary members of the specific binding pair.

Claims

1. A method for treating a wound or defect at a target site using a minimally invasive surgical procedure comprising:

providing a surgical access device having a plurality of reactive members of a specific binding pair releasably contained on an exterior surface of the access device, the reactive members having affinity for binding a cellular component of tissue cells located at the target site;

contacting the exterior surface of the access device with the tissue cells, wherein upon contact of the reactive members on the surface of the access device with the tissue cells, the reactive members are released from the exterior surface of the access device and bind to the tissue cells;

providing a tissue repair member having secured thereto a plurality of complementary reactive members of the specific binding pair; and

applying the tissue repair member to the tissue cells, wherein upon contact of the complementary reactive members on the surface of the tissue repair member with the reactive members on the tissue cells, covalent bonds are formed between the reactive members and the complementary reactive members, thus bonding the tissue repair member to the target site.

2. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 1 wherein the reactive members and the complementary reactive members of the specific binding pair bind to one another via a reaction selected from the group consisting of Huisgen cycloaddition reaction, a Diels-Alder reaction and a thiol-ene reaction.

3. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 2 wherein the reactive and the complementary reactive members of the specific binding pair are alkynes and azides.

4. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 3 wherein the reactive members are alkynes and the complementary reactive members are azides.

5. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 4 wherein the reactive and complementary reactive members of the specific binding pair are dienes and alkenes.

6. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 3 wherein the reactive members are azides and the complementary reactive members are alkynes.

7. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 2 wherein the reaction is catalyzed by copper to activate an alkyne and an azide for [3+2] cycloaddition.

8. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 2 wherein the reaction involves a cyclooctyne reagent and an azide for [3+2] cycloaddition.

9. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 2 wherein the reactive and complementary reactive members of the specific binding pair are thiols and alkenes.

10. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 2 wherein the complementary reactive members of the specific binding pair are secured to the tissue repair member by surface modification techniques selected from the group consisting of plasma treatment, silane coupling treatment and acid sensitization.

11. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 1 wherein a rapidly disintegrating coating on the exterior surface of the access device causes release of the reactive members of a specific binding pair.

12. The method for treating a wound or defect at a target site using a minimally invasive surgical procedure according to claim 11 wherein the rapidly disintegrating coating is made from a compound selected from the group consisting of sugar, poly(ethylene glycol), polyvinylpyrrolidone, poly(vinyl alcohol), hydroxypropyl cellulose, hydroxymethyl cellulose, hydroxypropyl methylcellulose, gelatin and combinations thereof.
