APPARATUS FOR CAPTURING OBJECTS BEYOND AN OPERATIVE SITE UTILIZING A CAPTURE DEVICE DELIVERED ON A MEDICAL GUIDE WIRE
First Claim
1. 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 flexible mounting member configured to slidably receive the guide wire, the resilient frame being attached to the flexible mounting member;
- a containment collar configured to slidably receive the guide wire there through and to receive at least part of the resilient frame therein; 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 flexible 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; and
moving the pull wire proximally relative to the resilient frame to retract the containment collar from the resilient frame.

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.

7. An apparatus for removing a solid object from a body canal or vessel, the apparatus comprising:
-
a guide wire; a sack having an apex; control arms attached to said sack and configured to bias said sack into an open position; wherein the improvement comprises a flexible frame in the form of a cylinder defining a lumen therethrough, said control arms and sack coupled to said flexible frame and configured to move with said flexible frame along said guide wire, said flexible cylinder frame being capable of rotation or linear movement when positioned on said guide wire, said flexible cylinder frame further configured to be firm axially, but pliable laterally, such that said flexible cylinder frame can conform to twists and bends taken by said guide wire during manipulation and advancement of whereby said flexible cylinder frame can bend and follow a path of said guide wire while avoiding axial elongation of said flexible cylinder frame. - View Dependent Claims (8, 9, 10)

11. An apparatus for removing a solid object from a body canal or vessel, the apparatus comprising:
-
A guide wire; a flexible frame member configured to slidably receive the guide wire; a sack having a mouth and a closed bottom opposite the mouth; a resilient frame connected between the flexible frame member and the sack for biasing the mouth of the sack open, 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 therethrough 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 flexible frame member 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
