1. An intravascular device comprising:
- an intravascular platform comprising;
a first proximal end and a second distal end;
a first closed loop of wire positioned at the first end of the intravascular platform, the first closed loop configured to assume a shape lying substantially on a virtual cylinder of given diameter;
at least one first connecting wire interconnected with, and extending from, said first loop toward the second end of the intravascular platform; and
a second closed loop of wire positioned at the second end of the intravascular platform and interconnected with said at least one first connecting wire, the second closed loop 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;
at least one second connecting wire interconnected with and extending distally away from the second closed loop of wire substantially parallel to the axis of the virtual cylinder; and
an intravascular filter interconnected to said second loop of the intravascular platform via the at least one second connecting wire and extending distally away from the second end of the intravascular platform, said intravascular filter being supported by said second loop,wherein a portion of a widest part of the intravascular filter that is coupled to the at least one second connecting wire has an outer diameter that is smaller than the diameter of at least one of the first closed loop and the second closed loop.

Abstract
An intravascular platform for supporting an intravascular device includes two loops of wire each configured to assume a shape lying generally on a virtual cylinder of given diameter. The two loops are interconnected by at least one connecting wire which maintains the loops axially spaced from each other. Also disclosed are axially-extended loop forms, and associated intravascular devices.

14. A method for deploying an intravascular device within a blood vessel, the method comprising:
deploying from a catheter located within the blood vessel an intravascular device comprising; a first closed loop of wire configured to assure a shape lying substantially on a virtual cylinder of given diameter; at least one first connecting wire interconnected within, and extending from, the first loop; a second closed loop of wire interconnected with said at least one first connecting wire and configured to assure a shape lying substantially on the virtual cylinder at a position displayed from the first loop in a direction substantially parallel to an axis of the virtual cylinder, such that the first loop is deployed from the catheter first and then the second loop is deployed from the catheter; and at least one second connecting wire interconnected with and extending distally away from the second closed loop of wire substantially parallel to the axis of the virtual cylinder, subsequently deploying an intravascular filter interconnected to the second loop via the at least one second connecting wire from the catheter, such that the intravascular filter is positioned upstream from the first loop and the second loop within the blood vessel, wherein a portion of a widest part of the intravascular filter that is coupled to the at least one second connecting wire has an outer diameter that is smaller than the diameter of at least one of the first closed loop and the second closed loop.
