摘要： A method of making a left ventricular assist device (LVAD) using muscle wrapped around a mandrel to form a muscle pouch, the open end of which is sewn to a circular sheet of patch material having connections to one end of each of a pair of vascular grafts, or alternatively to one end of a single vascular graft. The second ends of these vascular grafts are used to connect the LVAD to the aorta. After the muscle pouch has been formed around the mandrel, the mandrel is removed and replaced by a balloon which is inserted into the muscle pouch and inflated to maintain the desired shape of the muscle pouch during healing and stimulation of the pouch. The balloon is subsequently removed preceding activation of theLVAD to allow it to begin pumping blood. Alternatively, various other shape-maintaining forms which are expandable and collapsible may be used in place of the balloon. In another alternative embodiment, an additional strip of latissimus dorsi or other appropriate muscle or a mechanical clamping device may be used to synchronously compress the aorta between the ends of the vascular grafts anastomosed to the aorta.
摘要翻译：使用围绕心轴缠绕的肌肉来制造左心室辅助装置（LVAD）的方法，以形成肌肉袋，其开口端被缝合到具有与一对血管的每一个的一端连接的补片材料的圆形片移植物，或者替代为单个血管移植物的一端。这些血管移植物的第二端用于连接LVAD与主动脉。在心轴周围形成肌肉袋之后，心轴被移除，并被插入肌肉袋中的气球代替，并且在愈合和刺激小袋期间充气以保持肌肉袋的所需形状。随后在激活VAD之前移除气囊，以使其开始抽血。或者，可以使用可膨胀和可折叠的各种其它形状保持形式来代替气球。在另一替代实施例中，可以使用额外的背阔肌或其他适当的肌肉或机械夹紧装置的条带来同步地压缩主动脉在与主动脉吻合的血管移植物的端部之间。

摘要： The present invention is an improved method and apparatus for monitoring the status of particle filtration devices found in various filter units. The invention employs one or more light sources aimed across the filter units and one or more corresponding detectors that detect changes in light intensity from the light source. When a leak occurs whereby dust is released into the atmosphere around any given filter, the detectors will note a decrease in light intensity and will signal a problem. By using multiple light sources and detectors, or by getting signals from different angles from a single light source and detector, the present invention allows for quick and accurate pin-pointing of leakage problems.

摘要： The present invention is an improved printable sheet for use in a variety of applications requiring extreme image durability and weather (e.g., water) resistance. The printable sheet of the present invention employs an expanded polytetrafluoroethylene sheet comprising a series of polymeric nodes interconnected by fibrils. Images can be applied to this sheet using a variety of means, including pen and ink, electrostatic printing, screen printing, offset printing, etc. These images have proven to be very durable and capable of substantial wear, water exposure, and general abuse. Moreover, the printable sheet of the present invention is capable of being cleaned and reused over and over again once any given image is no longer of interest.

摘要： A surgical tool for use in preparing a graft path in anterior cruciate ligament reconstruction in a knee joint in which aligned tibial and femoral osseous tunnels are made for a bone-tendon-bone graft or similar surgery where two bone tunnels are in alignment.The tool comprises an elongated guide body having a guide shaft capable of being positioned within the tibial tunnel and extending into the femoral tunnel, and an elongated channel-like main body which is coaxial with the guide shaft. The main body includes a rasping head and is rotatably and axially slidable on the guide shaft for guided rasping of bone surfaces along the graft path. The rasp head fully encircles the guide shaft and is capable of following the guide shaft to enter and extend beyond the tibial tunnel. The leading end of the guide body includes a guide head with a flexible structure for connecting the head to the guide shaft. The guide head is movable through the tibial tunnel and into the femoral tunnel to position the guide shaft for subsequent rasping of surfaces along the graft path by manually moving the rasping head along and/or about the shaft. The flexible connection of the guide head to the guide shaft enables the knee to be flexed, when the guide body is in place, for inspection of the graft path in the area of the intercondylar notch while the rasping body may serve as a trial prosthesis to check for interference.

摘要： An asymmetrical form of porous PTFE having substantially different dimensions at different points along the length of the form. If the form is, for example, a tubular form, the different dimensions may be thickness or diameter or both. The form is preferably a tubular form which is preferably tapered having opposing ends with large and small inside diameters respectively wherein the wall thickness of the large diameter end is greater than or equal to the wall thickness of the small diameter end. Tapered PTFE tubes of this type are particularly useful as implantable vascular grafts. A method of producing these asymmetrical porous PTFE forms is also described.
