Methods, systems, and devices for the delivery of endoluminal prostheses
View Patent ↗Described are devices, methods, and systems for achieving occlusion of vascular vessels. Further described are certain reduced or low profile procedures and devices for the percutaneous occlusion of the saphenous vein, such as in the treatment of a varicose vein condition caused by venous reflux.
1. A medical product for closing a vascular vessel of a patient, comprising:
an endoluminal delivery device having an atraumatic distal end, wherein the endoluminal delivery device is advancable through a vascular vessel; and
an occlusion device releasably received on the endoluminal delivery device;
wherein the occlusion device has sufficient column strength for sheathless advancement through the vascular vessel;
wherein the occlusion device includes a volume of occlusive material advanceable through the vascular vessel on the endoluminal delivery device and sufficient to close the vascular vessel;
wherein the occlusive material comprises sponge form material; and
wherein the occlusion device has a column strength between about 200 kPA and about 12,000 kPA
wherein the occlusion device is at least about 10 cm in length;
wherein the occlusion device defines an aperture extending longitudinally therethrough for slidably receiving a wire guide; and
wherein the sponge form material expands to close the aperture after removal of the wire guide.
2. The medical product of claim 1 , wherein the endoluminal delivery device comprises one or more adaptations for releasably receiving the occlusion device.
3. The medical product of claim 1 , wherein the endoluminal delivery device comprises an aperture for receiving a wire guide.
4. The medical product of claim 1 , wherein the endoluminal delivery device is self-guiding.
5. The medical product of claim 4 , wherein the endoluminal delivery device is configured for vascular access through an introduction device.
6. The medical product of claim 5 , wherein the introduction device comprises a cannulated device.
7. The medical product of claim 1 , wherein the occlusion device comprises biocompatible material.
8. The medical product of claim 7 , wherein the biocompatible material comprises a remodelable material or a synthetic material.
9. The medical product of claim 8 , wherein the remodelable material comprises an extracellular matrix material or an absorbable material.
10. The medical product of claim 9 , wherein the extracellular matrix material comprises submucosa.
11. The medical product of claim 10 , wherein the submucosa comprises small intestine submucosa.
12. The medical product of claim 11 , wherein the small intestine submucosa comprises porcine small intestine submucosa.
13. The medical product of claim 1 , wherein the occlusion device is up to 60 cm in length.
14. The medical product of claim 1 , wherein the occlusion device is at least 25 cm in length.
15. The medical product of claim 1 , wherein the occlusion device is at least 35 cm in length.
16. The medical product of claim 1 , wherein the occlusion device is at least 50 cm in length.
17. The medical product of claim 1 , wherein the volume of occlusive material is expandable from a first configuration arranged for advancement through the vascular vessel to a second configuration arranged to close the vascular vessel.
18. The medical product of claim 1 , wherein the volume of occlusive material is compressed in the first configuration and effective to expand when wetted with water or other fluid.
19. The medical product of claim 1 , wherein the sponge form material comprises collagen.
