Apparatus for capturing objects beyond an operative site utilizing a capture device delivered on a medical guide wire

Abstract

An apparatus for removing a solid object from a body canal or vessel includes a coil of wire configured to slidably receive a guide wire and a sack having a mouth and a closed bottom opposite the sack. A resilient frame is connected between the coil of wire and the sack for biasing the mouth of the sack open around the coil of wire. The resilient frame is positionable between a collapsed state where the mouth of the sack is closed against the bias of the resilient frame and a deployed state where the mouth of the sack is biased open by the resilient frame.
