摘要： A delivery catheter for delivering, orienting and releasing an endoprosthetic implant in a body lumen includes an elongate sheath adapted to maintain an expandable implant in a low profile configuration at the distal end of the sheath and a control handle at the proximal end of the sheath. An implant retainer is engageable with the trailing end of the implant and is connected to the handle. The implant retainer is controllably movable within the sheath to enable relative movement between the sheath and the implant. The sheath can be moved between a forward implant-capturing position in which the implant retention device is contained within the sheath and a rearward implant release position in which the implant retainer is disposed forwardly beyond the end of the sheath. A moveable mechanism associated with the handle includes detents to limit the extent of movement of the moveable portion of the handle to provide a sequential stage control that requires deliberate manipulation of the handle in order to progress from one stage of the delivery cycle to another.
摘要翻译：用于在体腔内递送，定向和释放内假体植入物的递送导管包括细长护套，其适于将护发素的远端处的低轮廓构造的可扩张植入物保持在护套的近端处的控制手柄。植入物保持器可与植入物的尾端接合并连接到手柄。植入物保持器可控制地在护套内移动以使护套和植入物之间能够相对移动。护套可以在其中植入物保持装置容纳在护套内的正向植入物捕获位置和向后植入物释放位置之间移动，其中植入物保持器向前设置在护套的端部之外。与手柄相关联的可移动机构包括限制手柄的可移动部分的移动程度的棘爪，以提供顺序级控制，其需要对手柄进行有意的操纵，以便从输送周期的一个阶段进行到另一阶段。

摘要： A self-sealing hemostatic valve for use in a catheter apparatus is disclosed, comprising a proximal valve element having a sealing hole, a distal valve element having a flap and biasing means to enhance the force with which the flap bears against the distal side of the proximal valve element to normally seal the hole. The sealing hole seals about an instrument passed through the valve and the flap seals the valve when no instrument is present. The proximal face of the proximal valve element is provided with discontinuities that increase the flexibility of the proximal valve element in a distal direction.

摘要： A steerable catheter includes control handle having a generally tubular housing with a longitudinal slot therein in which an axially or longitudinally movable tow-part slideblock resides, and a generally cylindrical, rotatably mounted thumbwheel surrounding a distal portion of the tubular housing, for controlling the axial translation of the slideblock. The pullwire passes into the distal end of the control handle and is only secured to the proximal part of the two-part slideblock so as to prevent the user from placing the pullwire under compression. A tip radius adjusting wire is attached to and extends distally from a slide actuator in the control handle into and through the main catheter shaft portion. The free distal end of the tip radius adjusting wire is selectably locatable at different positions. The radius of curvature of the tip portion, when deflected, depends upon how far distally into the deflectable tip portion the radius adjusting wire has been advanced by the user. The electrode catheter thus has a deflectable tip whose radius of curvature is adjustable over a relatively wide range.
摘要翻译：可操纵的导管包括控制手柄，其具有大致管状的壳体，其中具有纵向狭槽，其中轴向或纵向移动的牵引部件滑块位于其中，以及围绕管状壳体的远端部分的大致圆柱形可旋转地安装的指轮，用于控制轴向幻灯片的翻译。拉线进入控制手柄的远端，并且仅固定到两部分滑块的近端部分，以防止使用者将拉线放置在压缩状态。尖端半径调节线附接到控制手柄中的滑块致动器并远离其延伸并且穿过主导管轴部分。尖端半径调整线的自由端可选地位于不同位置。尖端部分的弯曲半径在偏转时取决于使用者已经使半径调节线前进到可偏转尖端部分的远端。因此，电极导管具有可偏转的尖端，其弯曲半径在相对宽的范围内是可调节的。

摘要： A balloon dilatation catheter comprising an elongated tubular shaft and an inner tube defining inflation and guide wire lumens. A dilatation balloon is mounted on the distal end of the tubular shaft and communicates with the inflation lumen. The guide wire lumen extends through the balloon. A stiffening wire is positioned within the tubular shaft and has a proximal end secured in the proximal portion of the catheter. The distal end of the stiffening wire is anchored within the inner tube in an area adjacent the guide wire entrance port. The stiffening wire maximizes strength to the proximal portion of the catheter while maintaining flexibility in the distal end of the catheter as well as the balloon.

摘要： An anti-obesity balloon and a placement system for the balloon includes a balloon (10) with a needle-pierceable, self-sealing plug (20) and an insertion catheter (12) having a needle (26) at its distal end. The needle (26) is movable between an extended position in which it protrudes distally of the insertion catheter (12) and a retracted position in which it is withdrawn interiorly of the insertion catheter (12). A handle arrangement (14) is provided at the proximal end of the insertion catheter to control the position of the needle (26). Means are provided for aspirating (16) and inflating (68) the balloon. The balloon structure (10) and insertion catheter structure (12) protect and enclose the sharp tip of the needle at all times during insertion and withdrawal of the insertion catheter (12). The insertion catheter (12) is detachable from the balloon (10), after the balloon (10) has been inflated in the patient's stomach, in a manner which imposes no force or load on the balloon.

摘要： A two-stroke pumping device for developing pulsatile fluid flow includes a housing with an internal resilient flexible element (66). The flexible element defines a pair of chambers within the housing, including a pumping chamber (62) and a driving chamber (64). The pumping chamber is connected to a source of the fluid to be pumped and the driving chamber is connected to a pneumatic pressure source adapted to create a pressure differential across the flexible element. The device includes a means responsive to the flexure of the element in the ejection stroke to terminate that stroke and begin the filling stroke. The flexible element oscillates to generate repetitive ejection and filling strokes.

摘要： A short backloading wire is provided to facilitate the backloading of a catheter onto a guidewire that has a tubular connector. This backloading wire is preferably shorter than the guidewire and at least one end is engageable with the hypotube connector at the proximal end of many guidewires. The free end of the backloading wire has a reduced diameter making easier to insert into the distal tip of a catheter during backloading.
