ABSTRACT:
An embolic protection device (2000) comprises a collapsible filter body (102), a filter support (103) for supporting the filter body (102), and a tubular member (108) to which the filter support (103) is mounted. The filter support (103) comprises two round wires (116). Each wire (116) has a “M”-shaped curve (120) in the wire (116) which acts as a strain distributing linking element. In an extended configuration, the concave portion of each curve (120) faces longitudinally in the distal direction. In a collapsed configuration, the concave portion faces radially inwardly towards the tubular member (108) and wraps around part of the tubular member (108) to define a compact, low-profile filter support (103). Tethers (500, 501) extend between the curves (120) and a sleeve (201) slidably mounted to the tubular member (108). The distal end of each tether (500, 501) is fixedly attached to the sleeve (201) and to the filter body (102). The sleeve (201) is slidable over the tubular member (108) between a pair of stops.
