VENO-MERSE/HARVESTER DEVICE
First Claim
1. A device for removing veins from the body of a patient comprising:
- a. a handle portion having first and second ends;
b. a hollow shaft portion extending from said second end of said handle portion, said shaft portion having a distal end;
c. a cutting portion extending from said distal end of said shaft portion, said cutting portion having a distal end; and
d. a cannula system for delivering a fluid near the veins fixedly incorporated within said handle portion, said hollow shaft portion and said cutting portion to form a closed system.

Abstract
A veno-merse/harvester device having a handle portion, a hollow shaft portion, and a cutting portion. A fixed cannula system incorporated in the device improves the hydrostatic pressure, which allows efficient hydro-dissection with less retrograde leak of tumescent fluid and facilitates the separation of the vein from surrounding tissues with less bleeding. The veno-merse/harvester device may incorporate a camera system to allow direct visualization of the side branches to be ligated during a procedure. The self-adjustable cutting tip facilitates the forward advancement of the veno-merse/harvester device safely over a dilated portion of a vein.

10. A device for removing veins from the body of a patient and providing visualization of the veins at a remove display device comprising:
-
a. a handle portion having first and second ends; b. a hollow shaft portion extending from said second end of said handle portion, said shaft portion having a distal end; c. a cutting portion extending from said distal end of said shaft portion, said cutting portion having a distal end; and d. a camera system for direct visualization of the veins, comprises a camera within said cutting portion and a transmission device within said shaft portion, wherein said camera captures said visualization and said transmission device transmits said visualization to a remote display device. - View Dependent Claims (11)
