An improved embolic filter frame is provided. The filter frame provides enhanced longitudinal compliance, improved sealing, low profile delivery, and short deployed length. The looped support struts have high “radial” stiffness with low “longitudinal” stiffness. When deployed, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains longitudinally compliant. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and as...
1. A method of making an embolic filter device, comprising: providing a cylindrical tube;providing a filter element;cutting the cylindrical tube to form a filter frame that includes: a collar that is adapted to be coupled to a support wire;a filter support portion; andmultiple support struts, each of which extends from the filter support portion to the collar; andattaching the filter element to the filter support portion,wherein at least one support strut of the multiple support struts has at least one portion with a bend equal to or greater than 90 degr...
