Multi-basket clot capturing device
First Claim
1. A method for removing a clot from vasculature of a patient, comprising the steps of:
- introducing a clot capturing device into a region of interest of the vasculature, the device comprising a distal basket connected to a wire and a proximal basket connected to a hypotube that is axially and slidably connected to the wire, the distal basket being operable to be positioned distal of and capture a distal portion of the clot and a proximal basket, each basket comprising a closed end and an open end and capable of moving from a collapsed state to an expanded state;
distally moving, relative to the hypotube, the wire connected to the distal basket distal to the clot thereby causing the distal basket to be positioned distal of the clot and expand to the expanded state away from a microcatheter connected to the wire and hypotube;
proximally moving the wire until the distal basket captures the distal portion of the clot;
thendistally moving the hypotube causing the proximal basket of the clot capturing device to be positioned proximal of the clot and expand to the expanded state, the proximal basket being operable to be positioned proximal of the clot and to capture a proximal portion of the clot; and
proximally moving the wire connected to the distal basket until contacting a distal end of the hypotube forming a cage around the clot between the opposing open ends of the proximal and distal baskets.

Abstract
A multi-basket clot capturing device that includes a distal basket connected to a wire. The distal basket may be positionable distal of the clot and operable to capture a distal portion of a clot. A proximal basket may be connected to a hypotube that is slidably axially connected to the wire. The proximal basket may be positionable proximal of the clot and operable to capture a proximal portion of the clot. A cage can form between the proximal and distal baskets around multiple portions of the clot for capturing the clot. Sliding the wire distally, or microcatheter proximally, relative to the clot causes the distal basket to move from a collapsed state to an expanded state. The cage may be around at least two portions of the clot that are opposed.
