1. An intra-vessel transcatheter filter device configured to capture and remove emboli for preventing distal embolization, the device comprising:
a tubular filter made of a flexible porous material, including a main body and a funnel,
the main body having a length configured to extend within a vessel zone,
the main body including
a distal end configured to be radially coupled with the vessel zone and hermetically sealed to the vessel zone when the device is in an active configuration, the distal end including a selectively actionable closure device so that the distal end is configured to open when the device is in the active configuration and close before a retraction of the device, and
a proximal end,
the funnel forming an extension of the main body, with a base of the funnel located at the proximal end; and
a support structure assembly including
a supporting catheter extending within the main body, the supporting catheter being a tubular body extending entirely through the main body from the proximal end to the distal end of the main body,
a radially expandable distal structure fixed to the distal end, and
a radially expandable proximal structure positioned in correspondence of the proximal end,
wherein the supporting catheter is directly attached to the radially expandable distal structure and the radially expandable proximal structure.
