摘要： A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.

摘要： A vessel harvesting system that is suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The system includes a vessel harvesting tool with an elongated cannula and a plurality of surgical instruments therein for separating the target vessels from the surrounding tissue and side branches. The harvesting tool includes a modular handle unit with a base attached to the elongated cannula and a sled that can adapt the base to various types of vessel severing/securing tools, such as tissue welders, bipolar scissors, and bipolar bisectors. The handle unit may be relatively rigid and integrated with the various tool movement controls to facilitate one-handed operation by a user. A severing/securing tool rotation mechanism may be incorporated within the handle and operated by a thumbwheel or other such mechanism. The vessel harvesting system may also provide distal CO2 insufflation for enhanced maintenance of the operating cavity.

摘要： An intravascular stent having struts which overlap, at least partially, when the stent is compressed. The overlapping struts allow the stent to be crimped to a smaller initial delivery diameter than may be achieved with non-overlapping designs for given metal density. The stent has a reduced delivery diameter which allows for the construction of reduced profile stent-delivery systems, which thereby allow for the stenting of smaller vessels than has heretofore been possible.

摘要： A stent for use in a patient's blood vessel to maintain the patency of the vessel contains strategically located radiopaque material. The strategic placement of the radiopaque material in the core structure of the stent functions to enhance the resolution of the stent under fluoroscopy. The initial part of the process includes forming a groove in a piece of tube stock and securing radiopaque material into the groove by press fitting or diffusion bonding. After the securing method, a layer of material can be sputtered coated over the only radiopaque material or over the entire stent. Finally, a pattern of struts and splines is cut into the tube composite to form the stent.
摘要翻译：用于患者血管中以维持血管通畅的支架包含有策略地定位的不透射线材料。不透射线材料在支架的核心结构中的战略布置有助于增强支架在荧光透视下的分辨率。该方法的初始部分包括在管坯中形成凹槽，并通过压配合或扩散粘合将不透射线材料固定到凹槽中。在固定方法之后，可以将一层材料溅射涂覆在唯一的不透射线材料上或整个支架上。最后，将支柱和花键的图案切成管复合物以形成支架。
