Guide wire device for removing solid objects from body canals

摘要

A vascular filter for capturing and removing emboli includes a sack having a mouth and a closed bottom opposite the mouth. A guide wire is received through the mouth of the sack and projected through the closed bottom of the sack. The closed bottom of the sack is connected to the projection of the guide wire therethrough. A collapsible frame is connected between the guide wire and the mouth of the sack. The collapsible frame biases the mouth of the sack open around the guide wire. A tube slidably receives the guide wire coaxially therein. The collapsible frame is moveable via the guide wire between outside the tube where the mouth of the sack is biased open by the collapsible frame and inside the tube where the mouth of the sack is closed, and vice versa.
