Patent ID: 8057507

Claim:
A vascular filter comprising: capture members configured to capture thrombus passing through a blood vessel, the capture members being movable from a capturing configuration to an open configuration, and support members for supporting the capture members, the support members, in an unconstrained condition, including: a proximal hoop extending circumferentially in a wave pattern; a distal hoop extending circumferentially in a wave pattern; and connecter elements extending from the proximal hoop to the distal hoop, wherein one or more of the connector elements bow toward a longitudinal axis of the filter when the capture members are in the capturing configuration, the one or more connecter elements being convex with respect to the longitudinal axis from the proximal hoop to the distal hoop when the capture members are in the capturing configuration, the one or more connector elements being configured to move outward when the capture members move to the open configuration, the one or more connecter elements being concave with respect to the longitudinal axis from the proximal hoop to the distal hoop when the capture members are in the open configuration.
