摘要： An apparatus includes an elongate body including a proximal end portion and a distal end portion and configured to be at least partially inserted into a body cavity. The elongate body defines a first passageway and a second passageway. The first passageway is configured to communicate fluid from the distal end portion in a first direction, and the second passageway is configured to communicate material from outside of the elongate body into the distal end portion in a second direction opposite the first direction and includes at least one port. An actuator is coupled to the elongate body and is configured to guide the distal end of the elongate body to an area of interest identifiable by a virtual colonoscopy.

摘要： A self-expanding endoluminal device comprising a tubular filamentary member having a hollow core for receiving a guidewire, the tubular member having a straightened configuration with the guidewire in the hollow core, a shape memory configuration without the guidewire in the hollow core, and an extension, optionally severable, accessible from outside of the body. The hollow core may be adapted to contain and elute or permanently contain a substance, which may be injected through the extension. A delivery system includes the guidewire, and a deployment method includes deployment with a proximal end of the extension accessible from outside of the body.

摘要： A thrombosis filter which can be securely affixed at a selected location in the vascular system of a patient and removed when no longer required. A first embodiment of the thrombosis filter includes a plurality of struts having a first grouping and a second grouping. The first grouping of struts and the second grouping of struts radiate in opposite directions. The free ends of the struts include anchoring elements which anchor into the walls of a blood vessel. At least one grouping of struts is comprised of a shape memory material. When these struts are at body temperature, their free ends engage the wall of the blood vessel. When the temperature of the shape memory alloy struts is selectively varied from body temperature, the struts retract into the body portion of the thrombosis filter. A second embodiment of the thrombosis filter includes a generally cylindrical anchoring portion, and a generally conical filtering portion, the filtering portion includes a plurality of elongated strands interwoven to create a pattern of cells. These strands extend beyond the filtering portion to comprise the anchoring portion. These strands are made of a shape memory material. At body temperature, the thrombus filter takes on an expanded shape. At a temperature other than body temperature, the thrombus filter assumes a contracted shape. When the thrombus filter assumes a contracted shape, the anchoring portion retracts away from the walls of the blood vessel. A method is also disclosed for removing the thrombus filter from a blood vessel. The method comprises changing the temperature of the thrombus filter so that it assumes a retracted shape then pulling the thrombus filter inside the lumen of a retrieval catheter.

摘要翻译： 一种血栓形成过滤器，其可以牢固地固定在患者的血管系统中的选定位置，并且在不再需要时被去除。 血栓形成过滤器的第一实施例包括具有第一分组和第二分组的多个支柱。 第一组支柱和第二组支柱沿相反方向辐射。 支柱的自由端包括固定在血管壁上的锚定元件。 至少一组支柱由形状记忆材料构成。 当这些支柱处于体温时，其自由端接合血管的壁。 当形状记忆合金支柱的温度从体温选择性地变化时，支柱缩回到血栓形成过滤器的主体部分。 血栓形成过滤器的第二实施例包括大致圆柱形的锚固部分和大致锥形的过滤部分，过滤部分包括交织以形成细胞图案的多个细长股线。 这些股线延伸超过过滤部分以包括锚固部分。 这些股线由形状记忆材料制成。 在体温下，血栓过滤器呈现膨胀形状。 在体温以外的温度下，血栓过滤器呈现收缩形状。 当血栓过滤器呈现收缩形状时，锚定部分从血管的壁缩回。 还公开了从血管中去除血栓滤过器的方法。 该方法包括改变血栓过滤器的温度，使其呈现缩回形状，然后将血栓过滤器拉回到取出导管的内腔内。

摘要： A prosthetic valve for implantation within a fluid conducting lumen within a body includes an elongate generally cylindrical radially collapsible valve body scaffold defining a fluid passageway therethrough for retentive positioning within the lumen. A radially collapsible leaf valve member is supported by the scaffold includes a number of valve leafs deflectable between a closed position restricting fluid flow through the passageway and an open position permitting fluid flow through the passageway. The leaf valve member includes an interior leaf valve frame defining a valve leaf aperture which is sealed by a fluid impermeable non-thrombogenic lining to prevent fluid flow therethrough.

摘要： An implantable bypass device establishes a bypass between an artery and a vein. The device includes an implantable venous connection graft in fluid communication along a vein. The connection graft includes an elongate tubular body, an elongate access lumen extending from an intermediate location of the tubular body. An elongate tubular bypass graft has end secured in fluid communication with an artery and the other end securable to a distal end of the access lumen for establishing fluid communication between the artery and the vein through the venous connection graft. The device provides enhanced life expectancy as well desirable visualization of arterial and venous flows through the device.
