Patent ID: 7753919

Claim:
A wire for removing an intravascular foreign body comprising: a flexible wire body possessing a central axis and a forward end; a branch part branching out from the forward end of the wire body; a plurality of filaments, each of the plurality of filaments extending across said branch part; the branch part and the filaments together forming a capturing space in which is to be captured a foreign body; the plurality of filaments comprising at least one first filament having opposite ends which are both axially movable relative to the branch part so that a loop formed by the at least one first filament and the branch part changes in size, the first filament lying entirely in a plane when the first filament is in a forward position for capturing the foreign body; the plurality of filaments also comprising at least one second filament having opposite ends which are both axially non-movable relative to the branch part; a movable body to which the ends of the at least one filament are connected so that with the foreign body positioned in the capturing space the movable body is movable to axially move the ends of the at least one first filament in a proximal direction relative to the branch part and relative to the at least one second filament to tighten the foreign body in the capturing space by engagement with the at least one first filament; and a continuation of the central axis of the wire body lying in said plane of the first filament.
