    • The present invention discloses devices and methods for performing intravascular procedures with out: cardiac bypass. The devices include various embodiments of temporary filter devices, temporary valves, and prosthetic valves. The temporary filter devices have one or more cannulae which provide access for surgical tools for effecting repair of the cardiac valves. A cannula may have filters of various configurations encircling the distal region of the cannula, which prevent embolitic material from entering the coronary arteries and aorta. The temporary valve devices may also have one or more cannulae which guide the insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve is a disc of flexible, porous, material that acts to filter blood passing therethrough. A set of valve leaflets extend peripherally from the disc. These leaflets can alternately collapse to prevent blood flow through the valve and extend to permit flow. The prosthetic valves include valve fixation devices which secure the prosthetic valve to the wall of the vessel. In one embodiment, the prosthetic valves have at least one substantially rigid strut, at least two expandable fixation rings located about the circumference of the base of the apex of the valve, and one or more commissures and leaflets. The prosthetic valves are introduced into the vascular system a compressed state, advanced to the site of implantation, expanded and secured to the vessel wall.
    • 本发明公开了用于进行血管内手术的装置和方法:心脏旁路。 这些装置包括临时过滤装置,临时阀和假肢阀的各种实施例。 临时过滤器装置具有一个或多个套管,其提供用于外科手术工具的进入以实现心脏瓣膜的修复。 套管可以具有围绕套管的远侧区域的各种构造的过滤器,其防止栓塞材料进入冠状动脉和主动脉。 临时阀装置还可以具有一个或多个引导阀插入主动脉的套管。 瓣膜装置在主动脉中扩张以占据血管的整个流动路径。 在一个实施例中,临时阀是柔性多孔材料的盘,其用于过滤血液中的血液。 一组瓣叶从圆盘外围延伸。

    • Devices and methods are disclosed for extracting fluids from within a container sealed by a cork or septum without removal of the cork or septum or the contamination of the fluid within the container by reactive gases or liquids. Embodiments of the device can include a needle connected to a valve which is in turn connected to a source of pressurized gas for displacing the fluid. Further embodiments of the device can comprise additional components that act to force the needle to be inserted through the cork or septum along a linear path, to aid in preventing buckling of the needle, to clamp the device to the container, to prevent expulsion of the cork or septum from the container, and to guide the needle through a specified region of the cork or septum. Various valves, pressure regulators, pressure ranges, needle geometries, gas selections are also presented. This device is particularly suited for the dispensing and preservation of wine.
    • 公开了用于从软木或隔膜密封的容器内提取流体的装置和方法,而不用软木或隔膜或通过反应性气体或液体污染容器内的流体。 该装置的实施例可以包括连接到阀的针,该针又连接到用于移动流体的加压气体源。 该装置的另外的实施例可以包括额外的部件,其用于迫使针沿线性路径插入软木或隔膜中,以帮助防止针的弯曲,将装置夹紧到容器,以防止排出 从容器中取出软木塞或隔膜,并引导针穿过软木塞或隔膜的指定区域。 还介绍了各种阀门,压力调节器,压力范围,针几何形状,气体选择。 该装置特别适用于酒的分配和保存。
