    摘要： An emboli filter for deployment in a body lumen to capture emboli entrained in a fluid flowing through the lumen includes a flexible elongated member sized to be passed through the lumen. A filter media is carried on and substantially surrounding the elongated member. The filter media has a first end secured to the elongated member adjacent the distal end. A second end of the filter media has a periphery movable toward and away from the elongated member. Opposing internal surfaces of the filter media define a volume into which emboli may flow through the second end when the periphery is moved away from the elongated member. The emboli are trapped within the volume when the periphery is moved toward the elongated member. An actuator moves the periphery toward and way from the elongated member. The actuator includes a plurality of elastic loops. The loops are biased to an open loop configuration with the loops urging the periphery away from the elongated member. The actuator is adapted to be manipulated by an operator to urge the loops against the bias to a closed position permitting movement of the periphery toward the elongated member without interference from the loops.

    摘要翻译： 用于部署在体腔中的栓塞过滤器以捕获夹带在流过管腔的流体中的栓塞，包括尺寸适于通过内腔的柔性细长构件。 过滤介质被承载并且基本上围绕细长构件。 过滤介质的第一端固定在与远端相邻的细长构件上。 过滤介质的第二端具有朝向和远离细长构件移动的周边。 过滤介质的相对的内表面限定了一个体积，当周边移动离开细长构件时，栓塞可以流经第二端。 当周边朝向细长构件移动时，栓塞被捕获在体积内。 致动器使周边朝向和远离细长构件移动。 致动器包括多个弹性环。 这些环被偏压到开环构型，其中环使得周边远离细长构件。 致动器适于由操作者操纵以将回路抵抗偏压推动到关闭位置，允许周边朝向细长构件移动而不受到环的干扰。

    摘要： Release mechanism for medical device includes a bushing having a proximal end, a distal end and a channel extending therethrough. Plurality of extend proximally from the distal end are biased toward a release configuration in which engagement surfaces at distal ends thereof retract radially into the channel. A core pin insertable through the channel applies a radially expansive pressure to move the arms radially outward to a locking configuration. Engagement surfaces of the first and second arms connect to a retaining surface of a tissue treatment device containing capsule, which extends at an angle relative to the engagement surfaces selected so that a first portion of a force transmitted along an axis of the bushing moves the arms radially inward toward the release configuration before a second portion of the force exceeds a threshold level associated with the removal of a tissue treatment device from gripped tissue.

    摘要： A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.
