Abstract:
1. An embolic protection device for collecting embolic debris within a body vessel having an inner wall, the embolic protection device comprising: a tubular frame having a lumen and a longitudinal axis, wherein a portion of the frame forms an annular closed loop having a collapsed state and an opened state; a telescoping portion having an end and being slidably received within the lumen of the closed loop of the frame to open the closed loop from the collapsed state to the opened state; a connecting portion including a first portion radially connected to the tubular frame and a second portion extending from the first portion to connect to the closed loop, the second portion being disposed coaxially with the tubular frame, the first portion being radially off-set from the centerpoint; and a filter connected to the frame to collect the embolic debris, the filter having a proximally located mouth portion, the annular closed loop being positioned within the filter to open the mouth portion towards the inner wall of the body vessel; wherein a radius of the opened state closed loop is adjustable based on a force applied to the end the telescoping portion by a fluid within the lumen of the frame, the force moving the telescoping portion along the longitudinal axis of the tubular frame with the fluid flowing from the connecting portion to the tubular frame.
