Abstract

A delivery sheath (50) for an intravascular emboli capturing filter (17) including an elongate tube having a distal region (54) having a reduced thickness distal wall region. The delivery sheath (50), according to the present invention, can have a thinner, softer, distal most portion for superior and more benigm interaction with vessel (12) interior walls. The present invention includes an intravascular emboli filter system including an elongate shaft having a distal region, an expandable emboli filter (17) operably coupled to the elongate shaft distal region, and an elongate sheath (50) having a lumen therethrough disposed over the elongate shaft. The elongate sheath (50) can have a distally decreasing outside diameter taper or reduced wall thickness region having improved atraumatic characteristics.
