    Abstract: Treatment of an aneurysm (16) or other vascular defect can be facilitated or enhanced by an implant (95) delivered with a thermally activated detachment system. A delivery system (10) can include an implant (95) with a proximal portion (53) that defines a port (54). A pusher device (78) can include arms (82) extending distally from a junction (80) of the pusher device (78) and through the port (54), with distal sections (84) of the arms disposed within the implant (95). The arms (82) can, at a certain temperature, transition from engagement with the implant (95) to a shape that facilitates release of the implant (95). Additionally or alternatively, a coil (182) can engage an outer surface of the implant (95) at the proximal portion (53) and transition to a shape that facilitates release of the implant (95).

    Abstract: 一种左心耳封堵器(200),包括密封部件(220)、位于密封部件(220)一侧的固定部件(210)、以及该连接密封部件(220)与该固定部件(210)的连接部件(230);该密封部件(220)的径向变形能力大于该固定部件(210)的径向变形能力和/或该密封部件(220)的轴向变形能力大于该固定部件(210)的轴向变形能力。该左心耳封堵器(200)设置密封部件(220)的径向或轴向变形能力大于固定部件(210)的径向或轴向变形能力,可以避免固定部件(210)放置在左心耳(10)中后,密封部件(220)不能最佳地和左心耳(10)的口部贴合,从而增强了封堵效果;同时因密封部件(220)的变形能力较大,还可降低密封部件(220)磨损或磨破左心耳口部的风险;在保证前两点的前提下,固定部件(210)使封堵器更好地固定在左心耳(10)中,避免封堵器(200)从左心耳中脱落。

    Abstract: The present disclosure relates to devices and methods for forming occlusions. An occlusion forming device includes a delivery catheter and a magnetic component disposed a distance in a distal direction from a distal end of the delivery catheter. A connecting member extends between the magnetic component and the delivery catheter and is detachably coupled to the delivery catheter by a connector. The delivery catheter is configured to direct an occlusion forming, magnetic responsive fluid to a treatment site, where the magnetic component draws the fluid out and away from the distal end of the delivery device. The connecting member and magnetic component are configured to be detached from the delivery catheter so that the delivery catheter can be removed from the treatment site.

    Abstract: An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) and a covering material (1110, 1412, 1612, 1812, 1912, 210, 2214, 2314, 510, 810). In some embodiments, the frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) includes a single continuously wound wire that defines an apposition portion (1020, 120, 130, 1420, 1820, 1920, 1, 420, 720), a defect-occupying portion, and a sealing portion (1030, 130, 1430, 1830, 1930, 430, 730). In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the Gl tract including the small bowel and colon. In some embodiments, a two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700)
