Patent ID: 6893451

Claim:
An apparatus for removing a solid object from a body canal or vessel, the apparatus comprising: a coil of wire configured to slidably receive a guide wire; a sack having a mouth and a closed bottom opposite the mouth; a resilient frame 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 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; a containment collar configured to slidably receive the guide wire theretbrough and to receive at least part of the resilient frame therein; and a pull wire connected to the containment collar, wherein in response to relative movement between the guide wire and the pull wire, the resilient frame is positionable between the collapsed state at least partially inside the containment collar and the deployed state outside the containment collar.
