A seamless, self-expanding implantable device having a low profile is disclosed along with methods of making and using the same. The implantable device includes a frame cut out of a single piece of material that is formed into a three-dimensional shape. The implantable device may comprise an embolic filter, stent, or other implantable structure. The present invention also allows complicated frame structures to be easily formed from planar sheets of starting material, such as through laser cutting, stamping, photo-etching, or other cutting techniques.

1. 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 coupled to a positioning element; anda filter media attached to the support member, wherein the filter media is adapted to permit blood to pass through the filter media and to reduce passage of embolic debris through the filter media. 2. The device of claim 1, wherein the positioning element comprises a guide wire or a support wire. 3. The device of claim 1, wherein the support member is circumferentially disposed about an axis defined by the positioning element. 4. The device of claim 1, wherein the frame includes at least two support members, and wherein each strut of the plurality of struts extends in a generally proximal direction from a proximal support member of the at least two support members. 5. The device of claim 4, wherein the at least two support members define a plurality of diamond-shaped cells of the frame. 6. The device of claim 1, wherein the blood vessel is a vena cava. 7. The device of claim 1, wherein the filter media substantially covers the support member. 8. The device of claim 1, further comprising at least one radiopaque marker disposed on the frame, wherein the radiopaque marker comprises a material with greater radio-opacity than the frame. 9. The device of claim 1, wherein the filter media comprises a pharmacological agent. 10. The device of claim 1, wherein the filter media comprises at least two layers. 11. The device of claim 1, wherein the struts are configured to be more flexible than the support members. 12. The device of claim 1, wherein the filter media has a substantially parabolic configuration or a substantially tapered configuration. 13. A method of filtering blood in a blood vessel of a patient, comprising: providing a filter 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 coupled to a positioning element; anda filter media attached to the support member, wherein the filter media is adapted to permit blood to pass through the filter media and to reduce passage of embolic debris through the filter media; andpositioning, using the positioning element, the filter device at an deployment site within the blood vessel of the patient. 14. The method of claim 13, wherein the blood vessel is a vena cava. 15. The method of claim 13, wherein the deployment site within the blood vessel of the patient is a first deployment site, and further comprising, after positioning the filter device at the first deployment site, moving, using the positioning element, the filter device to a second deployment site within the blood vessel of the patient. 16. The method of claim 15, wherein the moving of the filter device comprises capturing the filter device within a catheter. 17. The method of claim 13, wherein the positioning element comprises a guide wire or a support wire. 18. The method of claim 13, further comprising at least one radiopaque marker disposed on the frame, wherein the radiopaque marker comprises a material with greater radio-opacity than the frame. 19. The method of claim 13, wherein the filter media comprises a pharmacological agent.
