    摘要： A medical device is provided. The medical device includes a vessel-engaging member attached to a distal end of a delivery wire via a connection mechanism. The vessel-engaging member includes a plurality of rows and a plurality of bridges positioned between each adjacent row, each of the bridges connecting a vertex of a first row with a corresponding vertex of a second row. The vessel-engaging member further includes first and second tapered sections coupled to the connection mechanism, each of the tapered sections projecting from a proximal row and tapering in a direction from the proximal row toward the connection mechanism, each of the tapered sections having a length measured along a longitudinal axis, wherein the length of the first tapered section is less than the length of the second tapered section.

    摘要： A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a valve body defining a ventricular end of the device, and an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom and adapted to engage the native mitral annulus and/or the native leaflet(s) of the human heart. The atrial flange can be seated in the atrium above the native mitral valve annulus in a human heart, and the ring of tabs can engage the native mitral annulus in a manner where the atrial flange and tabs provide a clipping effect to secure the mitral valve replacement device at the native mitral valve position.

    摘要： A stent delivery device includes a first retaining polymer disposed about and retaining a self-expanding stent at a proximal end portion, a second retaining polymer disposed about and retaining the self-expanding stent at a distal end portion, a first resistance member in thermal communication with the first retaining polymer, and a second resistance member in thermal communication with the second retaining polymer. The second retaining polymer and second resistance member are configured to allow release and expansion of the distal end portion of the self-expanding stent without expansion of the proximal end portion of the self-expanding stent.
