The method of claim 12, further comprising, after detaching the positioning element from the connecting member, retrieving and removing the occluder device from the blood vessel of the patient. 15. The method of claim 12, wherein the positioning element comprises a guide wire. 16. The method of claim 12, wherein the positioning element comprises a support wire. 17. A method of occluding a blood vessel of a patient, comprising: providing an occluder device that comprises: a unibody and seamless frame that includes a support member and a plurality of struts, wherein each strut of the plurality of struts extends from the support member to a connecting member that is detachably coupled to a positioning element via a coupling feature; andan occluder media attached to the support member, wherein the occluder media is adapted to substantially obstruct blood flow through the occluder media;positioning, using the positioning element, the occluder device at a first deployment site within the blood vessel of the patient;moving, using the positioning element, the occluder device to a second deployment site within the blood vessel of the patient; anddetaching the positioning element from the connecting member. 18. The method of claim 17, wherein the moving of the occluder device using the positioning element to a second deployment site includes capturing the occluder device within a catheter. 19. A device for filtering blood in a blood vessel of a patient, comprising: a unibody and seamless frame that includes a support member and a plurality of struts, wherein each strut of the plurality of struts extends from the support member to a connecting member that is detachably coupled to a positioning element via a coupling feature; anda filter media attached to the support member, wherein the filter media is adapted to permit blood to pass through the filter media to not permit embolic debris to pass through the filter media. 20. The device of claim 19, wherein the positioning element comprises a guide wire. 21. The device of claim 19, wherein the positioning element comprises a support wire. 22. The device of claim 19, wherein the coupling feature comprises a threaded coupling. 23. The device of claim 19, wherein the coupling feature comprises a magnetic coupling. 24.
