Recovery catheter assembly

A recovery catheter assembly comprising:

• a first actuator element;
• a second actuator element;
• a mechanically radially expandable and contractible recovery device operably connected to the the first actuator element and the second actuator element, the recovery device having a proximal end operably connected to the first actuator element and a distal end operably connected to the second actuator element;
• the recovery device comprising:
• proximal and distal blocking portions at the proximal and distal ends thereof;
• and
• a central portion between the proximal and distal blocking portions;
• the recovery device at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the first actuator element and the second actuator element so that when in the second, radially expanded configuration the proximal and distal blocking portions have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion, the manipulation of the first actuator element and the second actuator element comprises movement of the first actuator element and the second actuator element with respect to the recovery device.
