A biomedical shape-set textile structure based mechanical thrombectomy systems and methods are described. In one of the embodiments, the mechanical thrombectomy device can be customized to the length of the clot in each patient. In one of the embodiments, the mechanical thrombectomy device because of the textile structure has a very low overall profile or thickness that is less than 0.0125 inches (0.317 mm) and therefore can be deployed within microcatheters with inner lumen diameter as small as 0.014 inches (0.355 mm).
1. A thrombectomy device comprising: a plurality of wires woven to form a textile structure having a collapsed configuration and an expanded configuration, the textile structure comprising five to ten self-expanding bulbs in the expanded configuration, at least three of the five to ten self-expandin
1. A thrombectomy device comprising: a plurality of wires woven to form a textile structure having a collapsed configuration and an expanded configuration, the textile structure comprising five to ten self-expanding bulbs in the expanded configuration, at least three of the five to ten self-expanding bulbs having different outer diameters in the expanded configuration, a proximal end bulb of the five to ten self-expanding bulbs larger than at least one middle bulb of the five to ten self-expanding bulbs in the expanded configuration, wherein the plurality of wires comprises shape memory wires and radiopaque wires, and wherein the radiopaque wires are circumferentially clustered to enhance visibility under x-ray; anda delivery system proximal to the textile structure. 2. The device of claim 1, wherein at least one of the self-expanding bulbs has a spherical shape in the expanded configuration. 3. The device of claim 1, wherein the textile structure comprises five said self-expanding bulbs. 4. The device of claim 1, wherein the textile structure comprises six said self-expanding bulbs. 5. The device of claim 1, wherein the textile structure comprises ten said self-expanding bulbs. 6. The device of claim 1, wherein the delivery system comprises a multi-filament hybrid. 7. The device of claim 1, wherein the delivery system comprises a hypotube. 8. The device of claim 1, wherein the delivery system comprises a multi-filament hybrid, wherein the textile structure comprises six said self-expanding bulbs, wherein at least one of the self-expanding bulbs has a spherical shape in the expanded configuration. 9. The device of claim 1, wherein the delivery system comprises a multi-filament hybrid, wherein the textile structure comprises six said self-expanding bulbs, wherein each of the self-expanding bulbs has a spherical shape in the expanded configuration, and wherein the delivery system is coupled to the textile structure using solder comprising radiopaque material. 10. A thrombectomy device comprising: a plurality of wires woven to form a textile structure having a collapsed configuration and an expanded configuration, the textile structure comprising: five to ten self-expanding bulbs in the expanded configuration, the five to ten self-expanding bulbs in the expanded configuration comprising three or more sizes in series and a proximal end bulb of the five to ten self-expanding bulbs larger than at least one middle bulb of the five to ten self-expanding bulbs in the expanded configuration, anda distal neck distal to and radially inward of a distal-most bulb of the self-expanding bulbs; anda delivery system having a distal end overlay bonded to the distal neck. 11. The device of claim 10, wherein the textile structure comprises six said self-expanding bulbs. 12. The device of claim 10, wherein the textile structure comprises ten said self-expanding bulbs. 13. The device of claim 10, wherein the delivery system comprises a multi-filament hybrid. 14. The device of claim 10, wherein the delivery system comprises a multi-filament hybrid, wherein the textile structure comprises six said self-expanding bulbs, wherein at least one of the self-expanding bulbs has a spherical shape in the expanded configuration, and wherein the plurality of wires comprises shape memory wires and radiopaque wires. 15. A thrombectomy device comprising: a plurality of wires woven to form a textile structure having a collapsed configuration and an expanded configuration, the textile structure comprising five to ten self-expanding bulbs in the expanded configuration, the five to ten self-expanding bulbs in the expanded configuration comprising three or more sizes in series and a proximal end bulb of the five to ten self-expanding bulbs larger than at least one middle bulb of the five to ten self-expanding bulbs in the expanded configuration;a delivery system proximal to the textile structure; anda bonding zone where the delivery system is coupled to the textile structure, the bonding zone comprising solder, the solder comprising radiopaque material. 16. The device of claim 15, wherein the textile structure comprises six said self-expanding bulbs. 17. The device of claim 15, wherein the textile structure comprises ten said self-expanding bulbs. 18. The device of claim 15, wherein the delivery system comprises a multi-filament hybrid. 19. The device of claim 15, wherein the delivery system comprises a multi-filament hybrid, wherein the textile structure comprises six said self-expanding bulbs, wherein at least one of the self-expanding bulbs has a spherical shape in the expanded configuration, and wherein the plurality of wires comprises shape memory wires and radiopaque wires.
