Patent ID: 7780696

Claim:
A distal protection filter assembly, comprising: an inner wire having a proximal end and a distal end and a longitudinal axis; a hollow tubular member disposed over the inner wire, the tubular member having a proximal end and a distal end; and a filter disposed over the hollow tubular member having a proximal end and a distal end, wherein the filter proximal end is attached to the hollow tubular member, wherein the filter distal end is fixed on the inner wire such that relative movement between the filter distal end and the inner wire along the longitudinal axis is prevented, and wherein relative movement between the proximal portion of the tubular member and the inner wire moves the filter from a collapsed insertion position to an expanded position and wherein further relative movement in the same direction between the proximal portion of the tubular member and the inner wire moves the filter to a retrieval position in which the filter is at least partially everted about the proximal portion of the tubular member.
