    摘要： Apparatus and methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

    摘要翻译： 本文描述了用于优化锚固力的装置和方法。 在固定组织褶皱时，通过利用具有可扩张臂的组织锚来避免直接位于锚固件正下方的组织的过度压缩，所述组织锚构造成使锚和组织之间的接触面积最小化。 当锚固件处于其膨胀构型时，将负载施加到锚固件，直到其被最佳地构造成适应一定范围的偏转，同时锚固件本身对组织施加基本恒定的力。 可以使用各种装置，例如止动件，弹簧构件，保险丝，应变计等来指示锚固件何时被偏转到最佳范围内的预定水平。 此外，影响锚固特征的其他因素包括例如改变锚的臂或支柱的数量，臂的定位，臂的构型，套环的长度等。

    摘要： The invention provides a nested tubing cannula which comprises outer and inner elongate tubular members, both having a proximal end, a distal end, and a lumen therebetween. The inner tubular member is sealed at its distal end and is nested substantially coaxially within the lumen of the outer tubular member, so that the gap between the inner and the outer tubular member defines a second lumen whereas the first lumen is the lumen of the inner tubular member. A tubular sleeve is disposed coaxially between the inner and outer tubular members. A balloon is mounted on a distal region of the outer tubular member and is in communication with the first lumen. The cannula further comprises a port proximal or distal the balloon occluder and is in communication with the second lumen. Methods for making the devices herein are disclosed.

    摘要： An endoscopic tissue anchor deployment device includes a handle, an elongated shaft defining an internal lumen, and an end effector attached to the distal end of the elongated shaft. A tissue anchor catheter is removably inserted through the lumen of the elongated shaft, the catheter having a tissue anchor assembly that is deployable from its distal end. In some embodiments, the handle includes a pin and track assembly that define a series of handle actuation steps corresponding to deployment steps for the deployment device end effector and the tissue anchor catheter. In some embodiments, the handle includes a catheter stop member that prevents movement of the tissue anchor catheter under certain circumstances, and a handle stop member that prevents actuation of the handle under certain circumstances.

    摘要： A bendable shape-retaining cannula and methods of use. The bendable shape-retaining cannula comprises a tubular member having a proximal region, a distal region adapted to enter a blood vessel or heart chamber, a lumen therebetween, and a flexible region positioned proximal the distal region. A suture flange may be disposed about the cannula distal the flexible region. The flexible region can be bent and retains its bent configuration until a positive force is applied.

    摘要： Devices and methods for filtering blood. The devices generally comprise a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta, a structure adapted to open and close the mesh within the blood vessel, and a means to actuate the structure. The methods generally include the steps of introducing a mesh into a blood vessel to entrap embolic material, and removing the mesh and the entrapped foreign matter from the blood vessel.
