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.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to medical devices and in particular, a device for removal of veins from the body.BACKGROUND OF THE INVENTION

[0002] Veins are typically removed from the lower and upper extremities of the body for treating varicose veins, as well as harvesting veins for bypass procedures. Many prior art devices have been used in the past 100 years for removing the varicose veins of the lower extremities. Virtually all of them require major anesthesia at the hospital with potential complications and post-operative pain.

[0003] The practice of varicose vein treatment has changed dramatically over the last 10 years, making it an out-patient and less painful procedure, without the need for major anesthesia. The inventor's original harvester device and its subsequent improved version, disclosed in U.S. Pat. Nos. 7,163,547 and 7,632,289 and incorporated herein by reference, are used to remove the varicose veins of the lower extremities under local (tu...
