摘要
A device (2) for capturing and removing 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). Collapsible frame (8) can move 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 flame (8).
