Patent ID: 7048758

Claim:
A system for capturing embolic material which may be released into a blood vessel during a therapeutic interventional procedure by an interventional instrument at the site of a lesion in the blood vessel, in a collateral blood supply system adapted to enable the flow of blood to bypass the blood vessel upon blocking thereof and to enable the reverse flow of blood through the blood vessel upon unblocking thereof, the collateral blood supply system being a vascular system having a plurality of vessels including a common vessel which bifurcates into a first and second branch vessel, the system comprising: a first guide wire, including a distal end, adapted to be positioned in the first branch vessel; a guide catheter, including a distal end, adapted to enable the interventional procedure to be performed, and adapted to be inserted over the guide wire and through a patient's vasculature to a position in the common blood vessel; a first occluding device for occluding and blocking the first branch vessel attached to the first guide wire and adapted to be positionable at a location relative to the interventional procedure site and to enable the capture of embolic material which may be released into the blood in the blood vessel during the therapeutic interventional procedure; a second occluding device for occluding and blocking blood flow in the common blood vessel and to enable the capture of embolic material which may be released into the blood in the blood vessel during the therapeutic interventional procedure; and a second guide wire moveable within a lumen extending at least partially along the length of the guide catheter, the second guide wire being adapted to allow an interventional instrument to be slidably moved there along to the site of the interventional procedure in the second branch vessel.
