摘要： A device (9) for removing undesirable material from a tubular structure within the human body features a cylindrical body (9) with a lumen (12) therethrough. The distal portion of the body is divided into a number of flexible members (23). An inflatable cuff (26) is attached to the flexible members (23). When the cuff (26) is inflated, the members (23) flex radially outwardly so that the distal opening of the lumen (12) is expanded. An inflation tube (28) is used to inflate, and deflate the cuff (26) by means of a syringe (32). An elastomeric membrane sleeve (40) surrounds the flexible members (23) so that the latter are contracted towards their original position when the cuff (26) is deflated. The sleeve (40) also prevents material from escaping between the flexible members (23) when the cuffs (26) are inflated.
摘要翻译：用于从人体内的管状结构去除不需要的材料的装置（9）具有带有内腔（12）穿过的圆柱体（9）。主体的远端部分分成多个柔性构件（23）。可充气袖带（26）附接到柔性构件（23）。当袖带（26）膨胀时，构件（23）径向向外弯曲，使得腔（12）的远端开口膨胀。充气管（28）用于通过注射器（32）使袖带（26）膨胀和膨胀。弹性膜套筒（40）围绕柔性构件（23），使得当袖带（26）放气时，弹性膜套筒（40）收缩到其初始位置。当袖带（26）膨胀时，套筒（40）还防止材料在柔性构件（23）之间逸出。

摘要： An emboli capturing system (10) captures emboli in blood flowing in the vasculature. The emboli capturing system (10) includes a guidewire (14) having a longitudinal axis and defining a lumen along at least a portion thereof. An expandable member (20) is coupled to a distal portion of the guidewire (14) and has an interior being in fluid communication with the lumen in the guidewire. The expandable member (20) is configured to receive fluid through the lumen to expand radially outwardly relative to the guidewire (14) and have fluid removed from the interior thereof to collapse radially inwardly relative to the guidewire (14). The expandable member (20), when expanded, has a spaced portion thereof spaced radially outwardly from the guidewire (14). An emboli capturing device is coupled to the expandable member (20) and is configured to deploy radially outwardly relative to the guidewire (14) upon expansion of the expandable member (20).

摘要： A tissue retrieval apparatus for laparoscopic procedures includes a longitudinally extending tube (22) having a tip end (24) insertible into a patient. The tip end (24) is formed to be radially expandable in response to withdrawal of tissue (15) into the tip end (24) of the tube. Tissue can be withdrawn into the tip end (24) of the tube (22) by using graspers (42) or other devices that can be extended to engage and hold tissue. To reduce the possibility of contamination of healthy tissue, an elastic sheath (30) is attached to cover the tip end (24) of the tube (22). The elastic sheath (30) is formed to radially expand in response to radial expansion of the tip end (24) of the tube (22) during withdrawal of tissue into the tip end (24) of the tube (22).

摘要： A tissue retrieval assembly (210) includes an expandable outer cannula (212) partially covered by an elastic sheath (242). A rotary cutter assembly is positioned inside the outer cannula (212). The rotary cutter assembly includes a rotary cutter (276) surrounded by an inner cannula (272) positioned to locate the rotary cutter (276) near the distal end of the outer cannula (212). The inner cannula (272) is fluidly coupled to a vacuum source (230). As tissue is presented to the distal end of the cannula (212), the vacuum source (230) draws the tissue into the rotary cutter assembly, where it is chopped up by the rotary cutter (276) and removed from the inner cannula (272).

摘要： An endoscopic device includes: a hollow tube with a proximal end and a distal end. The proximal end and the distal end form a fluid communication therebetween. The proximal end is removably coupled with a distal tip of an endoscope and where coupled, forms a substantially airtight connection with the distal tip of the endoscope. The distal end removably contacts an object to be retrieved so as to deliver a suction force provided by the endoscope to facilitate removal of the object.

摘要： An assembly for tethering a medical device to a delivery catheter includes a tether, a collet, and a spring-biased holding element that is coupled to a distal end of the tether and that extends around the collet, being moveable between first and second positions. At the first positon, corresponding to the spring bias thereof, the holding element prevents fingers of the collet, which are configured to grip a proximal end of the device, from opening; at the second position, the collet fingers are allowed and/or caused to open. The assembly is coupled to a tubular member of the catheter, and, when the tethering assembly abuts a distal end of the catheter tubular member, a pull force applied to a proximal end the tether, which extends out from a proximal opening of the catheter, moves the holding element from the first position to the second position.
