A device for removing a filter element from a retrieval catheter is provided. The device includes a core member which has a diameter corresponding to a filter element; a handle at a proximal end of the core member; and an engagement portion, formed at a distal end of the core member, for engaging the filter element. Alternatively, the device includes a first member including a core wire, a core wire handle; and an engagement portion, and a second member including a hypotube; and a hypotube handle, wherein the core wire is moveably disposed coaxially inside of the hypotube, such that when a distal end of the core wire handle is pressed against a proximal end of the hypotube handle, the engagement portion of the first member extends beyond a distal end of the hypotube. Alternatively, the device includes a partially cylindrical member, a handle; and at least one blade.
