1. A vascular filter capable of converting into a tubular stent, comprising:

  • a resilient lattice that tends to expand from a compressed shape to an expanded shape;

    a proximal and distal balloon-expandable stent affixed to proximal and distal ends of the resilient lattice, the balloon-expandable stents having an initial crimped diameter and tending to retain said crimped diameter;

    wherein the balloon-expandable stents to hold the proximal and distal ends of the resilient lattice closed to a relatively small profile, and being capable of being forcibly expanded to a larger diameter, such that the lattice and stents form a tubular composite stent defining an open lumen.
