An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of “radial” stiffness with a low degree of “longitudinal” stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are t...
1. An embolic filter comprising: a support wire;an embolic filter frame having a filter support portion which is circumferentially disposed about the support wire and multiple support struts, each of the multiple support struts affixed to a collar and mounted to the support wire via the collar;the support struts extending radially from the support wire;at least one support strut having a looped configuration when not in tension in a deployed state;the at least one support strut positioned essentially within a plane of an opening of the filter when in the...
