摘要： A percutaneous implanted device for temporarily sustaining a patient awaiting a heart transplant. The device includes a radially expandable stent mounted upon the balloon section of a balloon catheter. A venous biological valve is mounted at each end of the stent and an inflatable annular-shaped diaphragm is secured to the stent between the valves, which permit the flow of blood in one direction and prevent the flow of blood in the opposite direction. The diaphragm is attached to a pump which inflates the diaphragm after the stent is implanted in a blood vessel in relation to the heart's rhythm to assist the heart in moving blood through the patient's circulatory system.
摘要翻译：用于暂时维持等待心脏移植的患者的经皮植入装置。该装置包括安装在球囊导管的球囊部分上的可径向扩张的支架。静脉生物瓣膜安装在支架的每一端，并且可充气的环形隔膜固定在阀之间的支架上，这允许血液沿一个方向流动并防止血液沿相反方向流动。隔膜连接到泵上，该泵在支架植入相对于心脏节律的血管中之后使膜片膨胀，以帮助心脏通过患者的循环系统移动血液。

摘要： A thin walled needle having a body section containing a sharp tipped obturator for insertion into a fetal vessel or cavity through the mothers abdominal wall using ultrasonic imaging to guide and position the needle. After being located within a desired position within the vessel, the obturator is withdrawn from the body section and a balloon that is mounted upon the end of a catheter is past through the body section into a treatment region where the balloon is inflated. A sleeve is shrink fitted upon the needle body so that the air is trapped between the sleeve and the needle body which provide a bright ultrasonic echo. The distal end of the sleeve protrudes outwardly beyond the tip opening of the needle body so that when the catheter is withdrawn back into the needle body with the balloon in a deflated state, the balloon will slide easily into the sleeve protrusion and will be shaped by the sleeve so that it will move freely into the distal opening in the needle body without the danger of the balloon becoming snagged or hung up on the needle body.

摘要： A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.
