Patent ID: 7537601

Claim:
A method for deploying an apparatus for removing a solid object from a patient's vasculature, the apparatus including a guide wire, a resilient frame including a sack having a mouth and a closed bottom opposite the mouth, the resilient frame being 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 mounting member configured to slidably receive the guide wire, the resilient frame being attached to the resilient frame; a containment collar configured to slidably receive the guide wire therethrough and to receive at least part of the resilient frame therein; a deployment catheter has an end configured to abut an end of the mounting member; and a pull wire connected to the containment collar, wherein the pull wire has a proximal end which remains outside the body vessel during usage, the method including: deploying the guide wire within the patient's vasculature; sliding the mounting member, resilient frame and containment collar over the guide wire to position the resilient frame into a target area in the patient's vasculature; advancing the deployment catheter along the guide wire to a position in which the distal end of the deployment catheter abuts an end of the mounting member; and moving the pull wire proximally to retract the containment collar from the resilient frame.
