Prepackaged collections of the necessary devices and supplies (either custom or standard) designed for vessel harvesting using minimally invasive surgical procedures. Items in these kits usually include instruments appropriate for minimally invasive surgery (e.g., scalpels, dissectors, strippers, cautery probes), cannulae, blades, and other supplies. These kits may be supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Minimally invasive vessel harvesting kits are intended for dissecting veins (e.g., the saphenous vein) and arteries (e.g., the radial artery) from the limbs and/or the mammary artery from the thorax. Harvested vessels are mainly used as bypass grafts in coronary artery surgical procedures but are sometimes used to replace peripheral (e.g., lower limb) vessels; the kits may be also used for other dissection procedures (e.g., nerve dissection) through a surgically created subcutaneous cavity. Dedicated harvesting kits with a dedicated endoscope and a camera are also available.
