Intravascular guidewire filter system for pulmonary embolism protection and embolism removal or maceration

An intravascular guidewire filter system comprising:

• a delivery tube;
• a positioning tube having a proximal end and a distal end;
• a flexible capture sleeve having an expanded conformation and an unexpanded conformation and a proximal end and a distal end, said proximal end of said flexible capture sleeve is attached to said distal end of said positioning tube, the flexible capture sleeve being constructed of a woven mesh;
• a guidewire having a proximal end and a distal end;
• and
• at least two flexible preformed memory shaped filters attached to said guidewire, wherein said delivery tube, said flexible capture sleeve, and said guidewire form a telescopic system, and wherein distal progressive distal positioning of the delivery tube forcibly compresses the flexible capture sleeve, an underlying proximal filter and embolic debris which has been captured within the proximal filter, thereby dividing and macerating the embolic debris.
