Abstract
In at least one embodiment of the present invention, a retrieval device for entrapping and retaining a foreign object located in a body vessel for its extraction therefrom is provided. The device comprises a cage having a proximal end and a distal end and a longitudinal axis extending between the proximal and distal ends. The cage is radially expandable about the longitudinal axis to define an expanded state and to form an opening at the distal end for receiving the foreign object. The cage is collapsible to define a collapsed state and to retain the foreign object therein such that the foreign object is substantially aligned with the longitudinal axis. Extending proximally from the proximal end of the cage is a cable for retrieval of the device in the collapsed state.
