Benefits of technology

[0007] The present invention provides a fast, uniform, and inexpensive way to harvest a vessel for bypass surgery. An embodiment of the present invention comprises an internal stenting catheter with proximal and distal ends, a sheath catheter with proximal and distal ends, and a cylindrical cutting tube that is attachable to the distal end of the sheath catheter. The stenting catheter is

Problems solved by technology

However, typical procedures for harvesting a saphenous vein autograft are tedious, time consuming, and cause undesirable patient trauma.
The surgery required for harvesting a vessel in this manner is traumatic to the patient, increases recovery time, increases the patient's hospital confinement, and ad

Embodiment Construction

[0019] Turning now to FIGS. 1 and 2, the vessel harvester of the present invention is illustrated. The vessel harvester comprises a stenting catheter 11 with proximal and distal ends, a sheath catheter 13 with proximal and distal ends, and a cylindrical cutting tube 15 with a proximal cutting edge 43 and a distal connecting port 33. The stenting catheter is located within the lumen of the sheath catheter. Both the stenting catheter and the sheath catheter are illustrated within the lumen of a vessel 17 with side branches 18. The cutting tube, on the other hand, is located around the outside of the vessel. The cutting tube is connectably attached to the distal end 35 of the sheath catheter via the connecting port and the connecting prongs 29 and 31 located on the sheath catheter.

[0020] The stenting catheter 11 can be made out of an appropriately strong biocompatible material. The catheter can be made from an extruded biocompatible plastic such as polyurethane or polyethyl terephtala...

Abstract

The present invention is a method and device for harvesting a vessel. The vessel harvester comprises an internal stenting catheter with proximal and distal ends, a sheath catheter with proximal and distal ends, and a cylindrical cutting tube that is attachable to the distal end of the sheath catheter. The vessel harvester is used to harvest vesseal such as the greater and lesser saphenous veins, the basilic vein, the cephalic vein, and the radial artery.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an apparatus and method for harvesting vessels, especially veins, for use in bypass grafting surgical procedures. BACKGROUND OF THE INVENTION [0002] Atherosclerosis is a disease that affects hundreds of thousand of people each year. The disease can occur anywhere throughout the body including the lower extremities, the carotid arteries and the heart. When it affects the blood supply to the heart it is called coronary artery disease. Vascular complications produced by atherosclerosis, such as stenosis, aneurysm, rupture or occlusion oftentimes call for surgical intervention. If the disease is extensive, the affected artery or vessel is no longer reliable and is often replaced or bypassed around by a bypass graft, usually referred to as an “autograft.” To this end, the involved section of the vessel is bypassed with an autograft surgically attached proximal to the lesion and at a point distal to the lesion to provide a byp...
