Patent ID: 8840636

Claim:
A blood filter device, comprising: cannula having an outer surface, a distal end adapted to enter an artery, a proximal end adapted to receive blood from a bypass-oxygenator machine, and a lumen which extends longitudinally from the proximal to the distal end; and a filter, the filter comprising: an expansion frame attached to the cannula which is expandable between a compressed state and a radially expanded state; a mesh having a first edge attached circumferentially and continuously to the expansion frame; and a sleeve which circumferentially encloses the mesh and the expansion frame to reduce the profile of the mesh and the expansion frame when in the compressed state, said sleeve is operable to roll-up and thereby release the mesh and the expansion frame for deployment to the radially expanded state, wherein the sleeve is attached to the cannula distal to a second edge of the mesh, wherein the sleeve is attached to at least one roll-up control line and one unroll control line.
