Procedure Kit/Trays, Vessel Harvesting, Minimally Invasive, Endoscopic
Definition : Prepackaged collections of the necessary devices and supplies (either custom or standard) designed for vessel harvesting using a surgically inserted (tunneled) subcutaneous endoscope as a main component. Items in these kits usually include a dedicated endoscope with a video camera at its distal end, and several tools, such as dissecting and harvesting rods, that are introduced through a trocar and/or cannula. 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. Endoscopic vessel harvesting kits are used for dissection of veins (e.g., the saphenous vein) and arteries (e.g., the radial artery) from the limbs and/or the mammary artery from the thorax. Other harvesting kits based on a disposable cannula with a control and steering handle and a lumen intended for endoscope insertion are also available. The harvesting kits are frequently linked to external endoscopic surgical systems, including a monitor, a radiofrequency generator, an image processor, and light sources mounted on a cart or rack. Harvested vessels are used mainly as bypass grafts in coronary artery surgical procedures but are sometimes used to replace peripheral (e.g., lower limb) vessels; the kits may be used for other dissection procedures (e.g., nerve dissection) through a surgically created subcutaneous cavity. Harvesting kits based on a disposable cannula with a control and steering handle and a lumen intended for endoscope insertion are also available; the kits may be linked to external endoscopic surgical systems mounted on a cart or rack.
