Patent ID: 7211107

Claim:
An intravascular platform supporting an intravascular device, the platform comprising: (a) a first closed loop of wire configured to assume a shape lying substantially on a virtual cylinder of given diameter; (b) at least one connecting wire interconnected with, and extending from, said first loop; (c) a second closed loop of wire interconnected with said at least one connecting wire and configured to assume a shape lying substantially on the virtual cylinder at a position displaced from said first loop in a direction substantially parallel to an axis of the virtual cylinder; and (d) an intravascular filter interconnected to said second loop and deployed primarily on a side of said second loop away from said first loop, said intravascular filter being supported by said second loop, wherein said intravascular filter includes: (i) a first flexible elongated member configured to assume a substantially helical form extending for at least about one turn about the axis of said virtual cylinder, and (ii) at least a second flexible elongated member connected to said first flexible elongated member at at least two spaced apart connection positions chosen such that approximately equal lengths of said first and second flexible elongated members lie between said connection positions, said second flexible elongated member being configured to assume a predefined filter form lying substantially within said substantially helical form in such a manner as to form an obstacle to passage through said substantially helical configuration, in a direction parallel to said axis, of particles having dimensions greater than a predefined value.
