ABSTRACT:
Devices and methods for minimally invasive harvesting of a vessel or vascular conduit, especially the saphenous vein for coronary artery bypass grafting, are disclosed. Generally, an instrument is provided which has one or more specially designed end effectors which are permanently or detachably mounted to a harvesting implement, and may also be interchangeable with each other. The end effectors have features or elements which facilitate separation of connective tissue from the vessel and/or engagement of side branches to be separated from the vessel. In various embodiments, the instrument also provides means for quickly and easily attaching and detaching the end effectors as well as means for engaging with an endoscope, if desired. The harvesting methods provide for use of the instruments through one or more minimally invasive incisions.
