Abstract

A method for closing wounds and surgical incisions in mammalian tissue which comprises fastening an approximated wound or incision with a series of devices comprising a short filament with a head on each end, each device being surgically placed so that the filament traverses the wound or incision within the tissue while one head of the device engages the surface of the tissue on either side of the wound or incision. Apparatus is provided for the surgical placement of the device.

Claims

1. A method of closing a wound or incision in mammalian tissue to facilitate the healing thereof which comprises (a) approximating the tissue at the wound;

(b) inserting a hollow needle through the approximated tissue and across the wound whereby the needle is in communication with the surface of the tissue on either side of the wound;

(c) passing one end of a fastener device comprising a filament member terminated at each end by first and second anchoring means through the hollow needle until said first anchoring means at one end of the fastener device is discharged from the end of said needle external of said tissue on one side of said wound; and

(d) withdrawing the hollow needle from the tissue while maintaining the fastener device substantially stationary relative to the tissue until said fastener device is disengaged from the needle with said second anchoring means external of said tissue on the other side of said wound, whereby the fastener device remains in the tissue with the filament member traversing the wound through the tissue and with said first and second anchoring means maintaining the tissue in approximation at the wound from points on the surface of the tissue on either side of the wound.

2. A method of claim 1 wherein said anchoring means comprise rod members, each rod member being attached to said filament member at a point substantially equidistant from the ends of said rod member.

3. A method of claim 1 wherein said anchoring means comprise disk members, each disk member being attached to said filament member at a point substantially at the center of said disk.

4. A method of claim 1 wherein the fastener device is at least partially contained within the hollow needle while being inserted through the tissue.

5. A method of claim 2 wherein said hollow needle has a slot therein and one rod member of said fastener device is contained within said needle with the filament member extending from said needle through said slot while said fastener device is being inserted through the tissue.

6. A method of claim 1 wherein said fastener device is wholly contained within said hollow needle while being inserted through the tissue.

7. A method of claim 1 wherein a plurality of fastener devices are inserted through the tissue and across the wound along substantially the entire length of the wound.

8. A method of claim 1 wherein said fastener device is comprised of a non-absorbable material.

9. A method of claim 8 wherein the fastener device is comprised of nylon, polyolefin, or polyester.

10. A method of claim 8 wherein the filament member of said fastener device is comprised of a flexible, non-absorbable material and at least one of said anchoring means is comprised of a rigid, non-absorbable material.

11. A method of claim 10 wherein at least one of said anchoring means is stainless steel.

12. A method of claim 10 wherein said filament member is comprised of a multifilament suture material.

13. A method of claim 1 wherein said fastener device is comprised of a biologically absorbable material.

14. A method of claim 13 wherein said biologically absorbable material is selected from the group consisting of catgut, collagen, and homopolymers and copolymers of glycolide and lactide.

15. A method of claim 1 wherein the filament member of said fastener device is comprised of a biologically absorbable material and at least one of said anchoring means is comprised of a non-absorbable material.
