    • A device (2) for capturing and removing one or more particles (58) from a body canal or vessel includes a sack (12) having a mouth (14) and a closed bottom (16) opposite mouth (14). A guide wire (4) is received through mouth (14) of sack (12) and is connected to closed bottom (16) of sack (12). A collapsible frame (8) is connected between guide wire (4) and mouth (14) of sack (12), with collapsible frame (8) biasing mouth (14) of sack (12) opened around guide wire (4). A containment collar (32) slidably receives guide wire (4), collapsible frame (8), and at least part of sack (12) therein. A pull wire (34) is connected to containment collar (32). In response to relative movement between guide wire (4) and pull wire (34), collapsible frame (8) moves from inside containment collar (32) where mouth (14) of sack (12) is closed and outside containment collar (32) where mouth (14) of sack (12) is biased open by collapsible frame (8). Containment collar (32) has an axial length configured to be positioned entirely in a body and pull wire (34) has an axial length configured to extend from outside the body to containment collar (32) when it is positioned entirely in the body. Containment collar (32) can be removed from guide wire (4) by pulling pull wire (34) relative to guide wire (4) sufficiently that containment collar (32) is withdrawn from the body and from the end of guide wire (4) opposite collapsible frame (8).
    • 用于从身体管道或容器捕获和移除一个或多个颗粒(58)的装置(2)包括具有口(14)和相对于嘴(14)的封闭底部(16)的袋(12)。 引导线(4)通过袋(12)的口(14)接收并连接到袋(12)的封闭底部(16)。 可折叠框架(8)连接在袋(12)的导丝(4)和口(14)之间,其中可折叠框架(8)偏压围绕导丝(4)打开的袋(12)的口(14)。 容纳套环(32)可滑动地容纳引导线(4),可折叠框架(8)和其中的袋子(12)的至少一部分。 拉线(34)连接到收容套环(32)。 响应于导丝(4)和拉丝(34)之间的相对运动,可折叠框架(8)从袋(12)的口部(14)关闭的外部的容纳套环(32)内移动,并且外部的收容套环(32) 其中袋(12)的口(14)被可折叠框架(8)偏压打开。 容纳套环(32)具有构造成完全位于主体中的轴向长度,并且拉线(34)具有构造成当其完全位于主体中时从主体外部延伸到容纳套环(32)的轴向长度。 可以通过相对于导丝(4)拉动牵引线(34),使得容纳套环(32)从主体和导丝(4)的端部被抽出而能够从导丝(4)移除收容套环(32) 相对的可折叠框架(8)。
