Claim Text:
1. A vascular device, comprising: a frame attached to a distal end of a delivery wire, the frame comprising 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 when the frame has a first diameter; and 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 being coupled to a distal end of the frame via a plurality of connecting members, each of the connecting members extending from a distal end of a corresponding interconnecting member and converging distally to form a taper, each connecting member comprising a proximal segment and a distal segment, the proximal segment of each connecting member comprising one of (a) a cross section less than that of the distal segment of the corresponding connecting member or (b) a chain comprising a plurality of links and two individual rows coupled to each other, the proximal segments permitting the protector to radially expand independent of a radial expansion of the frame, the distal segments of the connecting members being configured to exert a second radial force, less than the first radial force, against the inner wall of the lumen when the protector has the first diameter.
