Abstract

A minimally invasive method for treating a varicose vein is provided. Generally, the method includes the opening of at least one small incision through a skin layer of the patient adjacent to the varicose vein. The varicose vein is then at least partially obstructed through the small incision. Thereafter, the incision is closed by conventional techniques. More specifically, the vein is at least partially obstructed by threading a suture through the small incision that extends through at least a portion of the vein. A plurality of small incisions in close proximity with the vein are opened with at least one of the plurality of small incisions being substantially centered over the vein. The suture is threaded through the substantially centered incision so that the suture penetrates through at least a portion of the vein. The suture is then withdrawn through another one of the plurality of small incisions. Next, the suture is re-threaded through the other one of the plurality of small incisions so that the suture penetrates through at least a portion of the vein in close proximity with the portion of the vein previously penetrated by the suture. Finally, the suture is re-withdrawn through the substantially centered incision. The threading, withdrawing, re-threading, and re-withdrawing steps are repeated with respect to each other one of the plurality of small incisions.

Claims

1. A minimally invasive method for treating a varicose vein, comprising the steps of:

ligating the junction between said vein and deep veins of the patient'"'"'s leg;

opening at least one small incision through a skin layer adjacent to a varicose region of said vein;

at least partially obstructing said vein through said at least one small incision; and

closing said at least one small incision.

2. The method of claim 1, wherein said at least partially obstructing step further comprises threading a suture through said at least one small incision that extends through at least a portion of said vein.

3. The method of claim 1, wherein said opening step further comprises opening a plurality of small incisions in close proximity with said vein with at least one of said plurality of small incisions being substantially centered over said vein.

4. The method of claim 3, wherein said at least partially obstructing step further comprises the steps of:

threading a suture through said at least one substantially centered incision so that said suture penetrates through at least a portion of said vein;

withdrawing said suture through another one of said plurality of small incisions;

re-threading said suture through said another one of said plurality of small incision so that said suture penetrates through at least a portion of said vein in close proximity with said portion of said vein previously penetrated by said suture; and

re-withdrawing said suture through said at least one substantially centered incision.

5. The method of claim 4, further comprising the step of repeating said threading, withdrawing, re-threading, and re-withdrawing steps with respect to at least one other one of said plurality of small incisions.

6. The method of claim 4, further comprising the step of tying exposed ends of said suture that extend outwardly of said vein through said at least one substantially centered incision.

7. The method of claim 6, further comprising the step of cutting said exposed ends of said suture that extend outwardly of said vein through said at least one substantially centered incision.

8. The method of claim 7, wherein said closing step further comprises the step of preventing any portion of said cut exposed ends of said suture from extending through said at least one substantially centered incision.

9. The method of claim 1, wherein said at least partially obstructing step further comprises injecting a rivet through said at least one small incision that extends through at least a portion of said vein.
