Abstract:
1. An intravascular filter for a vessel, comprising: a non-biodegradable apical hub; a plurality of non-biodegradable struts, each strut having a proximal section secured to the apical hub and a distal section rotatably connected to the proximal section at a link, the distal section extending generally distally away from the apical hub and extending radially outward from a longitudinal axis of the apical hub, the respective distal sections of the struts configured to exert an expansile force against an interior of the vessel; and at least one biodegradable element disposed along at least one strut encapsulating the link, the biodegradable element maintaining the expansile force prior to degradation and reducing the expansile force after degradation; wherein the distal section is non-unitary with and independent of the proximal section.
