Abstract
A vascular device is provided that includes a frame attached to a distal end of a delivery wire. The frame includes a cylindrical body formed of a plurality of interconnecting members, the interconnecting members being configured to exert a first radial force against an inner wall of an anatomical lumen. The vascular device further includes a protector having a proximal end, a distal end, and a profile that tapers distally from a proximal cross-sectional dimension to a reduced distal cross-sectional dimension. The protector is coupled to a distal end of the frame via a plurality of connecting members, each of the members extending from a distal end of a corresponding interconnecting member and converging distally to form a taper. The connecting members are configured to exert a second radial force, less than the first radial force, against the inner wall of the lumen.
