Abstract:
1. An embolic filter device, comprising: a support wire; a filter support portion and multiple support struts, wherein each of the multiple support struts extends from the filter support portion, and wherein the filter support portion is circumferentially disposed about the support wire; a collar that couples each of the multiple support struts to the support wire; and a filter element attached to the filter support portion, the filter element defining an opening that defines a filter opening plane; the embolic filter device having a constrained configuration while subjected to a radial constraint and an unconstrained configuration, wherein, in the unconstrained configuration, at least one support strut of the multiple support struts has at least one portion with a bend equal to or greater than 90 degrees, wherein the position of the collar can be offset proximally from the filter opening plane while the embolic filter device is in the constrained configuration, and wherein the collar is offset distally from the filter opening plane while the embolic filter device is in the unconstrained configuration.
