Abstract
An inner support structure for an embolic filtering device includes a tubular member having a first support region for supporting the proximal portion of a filter assembly and a second support region for supporting the distal portion of the filter assembly. The inner support structure facilitates rotation and restricts longitudinal movement of the embolic filtering device relative to a guide wire. Alternatively, the inner support structure includes a bushing coupled to the guide wire and a sleeve with a head on its proximal end positioned within a cavity in the bushing, thereby facilitating rotation and restricting longitudinal movement of the sleeve. The proximal portion of the filter assembly is supported on the sleeve. A sleeve for retaining the struts of an expandable cage of the embolic filtering device includes a central lumen for positioning the sleeve onto a guide wire and peripheral lumens for positioning and retaining the struts.
