    摘要: A distal protection device comprising a filter cartridge having a frame and filter material and a proximal region having a ridge adapted for interface with a retrieval device, wherein the retrieval device includes a distally located expandable cuff. The distal protection device is able to be deployed remotely in a body vessel lumen optionally using a guidewire and sheath and later retrieved using the retrieval device. A method of retrieving a cartridge from a body vessel lumen, the method comprising the steps of providing a filter cartridge disposed within a body vessel lumen; providing a retrieval device; advancing the retrieval device distally in the body vessel lumen until at least a portion of the retrieval device is distal the proximal most portion of the filter cartridge; engaging the filter cartridge with the retrieval device such that at least a portion of the filter cartridge is prevented from moving distally beyond at least a distal portion of the retrieval device; and advancing the retrieval device and the filter cartridge proximally from the body lumen.

    摘要: An intravascular guidewire having an articulating distal section for improved maneuverability beyond a lesion or other protrusion within a body lumen. An elongated core wire having an actuatable stop disposed thereon is adapted to have a reduced profile in a first position, and an enlarged profile in a second position. The actuatable stop can be adapted to expand by any number of means, including a spring coil, a polymeric tube or a mesh sleeve. In one particular embodiment, the actuatable stop comprises a distal section of a tubular member having a plurality of circumferentially disposed openings adapted to permit a plurality of struts disposed therebetween to expand in an outward direction when compressed axially.

    摘要: Devices and systems for retrieving an intravascular device within a body lumen are disclosed. The retrieval device may comprise an elongated tubular member having a relatively stiff proximal segment, an expandable distal segment, and an inner lumen disposed about a guidewire. The distal segment may include a braid configured to expand when axially compressed. A dilator tip operatively coupled to the elongated tubular member and guidewire may be used to track the retrieval device through the body.
