摘要： An embolic protection device (2000) comprises a collapsible filter body (102), a filter support (103) for supporting the filter body (102), and a tubular member (108) to which the filter support (103) is mounted. The filter support (103) comprises two round wires (116). Each wire (116) has a “M”-shaped curve (120) in the wire (116) which acts as a strain distributing linking element. In an extended configuration, the concave portion of each curve (120) faces longitudinally in the distal direction. In a collapsed configuration, the concave portion faces radially inwardly towards the tubular member (108) and wraps around part of the tubular member (108) to define a compact, low-profile filter support (103). Tethers (500, 501) extend between the curves (120) and a sleeve (201) slidably mounted to the tubular member (108). The distal end of each tether (500, 501) is fixedly attached to the sleeve (201) and to the filter body (102). The sleeve (201) is slidable over the tubular member (108) between a pair of stops.

摘要： A delivery catheter 1 has a distal pod 2 for reception of an embolic protection filter 3. The filter 2 is moved from a retracted delivery configuration to an extended deployed configuration by a push wire 6 which has an engagement hoop 7 at the distal end. Retraction of a handle 9 has the effect of retracting the pod 3 relative to the push wire 6 and the engagement hoop 7 and the filter 2 is effectively deployed by pushing it out of the pod 3.

摘要： A retrieval device (1) for retrieval of an embolic filter (2) from the vasculature (3) comprises a guide catheter (42), a retrieval catheter (10) and a centring catheter (11) which is threaded over a guidewire (25). The retrieval catheter (10) comprises an elongate flexible tube (15) including a radially expansible distal tip (19) with an open mouth (40) for retrieval of the embolic filter (2). The centring catheter (11) also comprises an elongate tube (20) which extends through the retrieval catheter tube (15) and terminates in a distal tapered end (21). The centring catheter (1) is used to centre the retrieval catheter (10) in the vasculature (3) to enable the retrieval catheter (10) to freely pass through a stenosis and/or stent to retrieve the filter (2). When the retrieval catheter (10) is in position the centring catheter (11) is withdrawn through the retrieval catheter (10).
摘要翻译：用于从脉管系统（3）检索栓塞过滤器（2）的检索装置（1）包括引导导管（42），取出导管（10）和定心导管（11），所述引导导管（10）和定心导管（11）穿过导丝）。取回导管（10）包括细长的柔性管（15），其包括具有用于抽吸栓塞过滤器（2）的开口（40）的可径向扩张的远端尖端（19）。定心导管（11）还包括延伸穿过取出导管（15）并终止于远端锥形端（21）的细长管（20）。定心导管（1）用于将取出导管（10）置于脉管系统（3）中，以使回收导管（10）自由通过狭窄和/或支架以取回过滤器（2）。当取回导管（10）就位时，定中心导管（11）通过取出导管（10）取出。
