Abstract:
1. An embolic filtering device for capturing embolic debris in a body fluid flowing within a body vessel, comprising: a guide wire having a proximal stop fitting and an intermediate stop fitting fixedly attached thereto; a support frame having a pre-deployment collapsed position and a deployed expanded position, wherein the support frame is made from a length of a single, continuous wire having a first end slidably attached to the guide wire between the proximal stop fitting and the intermediate stop fitting and a second end slidably attached to the guide wire at a location distal to the intermediate stop fitting; and a filtering element having a proximal inlet opening and a plurality of distal outlet openings, the outlet openings allowing the body fluid to flow through the filtering element but retaining embolic debris within the filtering element, and the inlet opening being larger than the outlet openings, wherein the entire length of the support frame is attached to opening the proximal opening of the filtering element to open the filtering element when the support frame is in the deployed expanded position.
