Abstract:
1. A recovery device assembly comprising: a proximal and a distal toroidal balloon blocking elements comprising an inner radius and partially defining a collection chamber; a central tubular section between and encircled by the two blocking elements and attached to their inner balloon inner radius walls; a recovery lumen housed within the inner radius walls of the toroidal balloons and the central tubular section with fenestrations through the wall of the recovery lumen and the central tubular section communicating with the collection chamber; an expansile structure adjacent to the recovery lumen, the expansile structure also housed within the inner radius walls of the toroidal balloons and the central tubular section, actuator elements attached to the expansile structure, wherein the recovery device is configured to be placed in a first radially collapsed configuration and in a second radially expanded configuration by manipulation of the actuator elements and inflation of the balloons so that when in the second, radially expanded configuration, the proximal and distal blocking elements have radial dimensions greater than the radial dimension of the central tubular section and the radial dimension of the central tubular section is greater than in the first radially collapsed configuration.
