Endovascular plasma treatment device and method of use
View Patent ↗A device and method for treating a hollow anatomical structure using matter in a plasma state. Device includes a tubular delivery device comprising a tubular body, a hub, and a distal end, wherein the tubular body device having a longitudinal fluid delivery channel and an exit port near the distal end. Device also contains a container having pre-plasma matter being operatively coupled to the hub, at least one energy-emitting element operatively coupled near the distal end of the tubular delivery device. The energy-emitting element is operatively connected to energy source.
1. An endoluminal treatment method comprising:
inserting into an anatomical lumen a catheter having at least one energy emitting element near the distal end of the catheter and a catheter lumen;
delivering pre-plasma matter in a gaseous state through the catheter lumen;
activating the energy emitting element to create plasma from the pre-plasma matter wherein the plasma causes shrinkage of the anatomical lumen.
2. A method of claim 1 , wherein the step of delivering the pre-plasma matter further comprises delivering the matter through an end hole of the catheter.
3. A method of claim 2 , wherein the step of delivering the pre-plasma matter further comprises delivering the matter through at least one side opening in the catheter.
4. A method of claim 3 , prior to delivering pre-plasma matter, further comprising inserting an occluding ball wire into the catheter lumen.
5. A method of claim 1 , wherein the step of inserting includes the energy emitting element comprising an optical fiber.
6. A method of claim 1 , wherein the step of inserting includes the energy emitting element comprising an electrode.
7. A method of claim 6 , wherein the electrode further comprises a radiofrequency electrode.
8. A method of claim 1 , wherein the step of inserting includes the energy emitting element comprising a beacon capable of receiving ultrasound waves.
9. An endoluminal treatment method comprising:
inserting into a varicose vein a catheter having a lumen, an energy emitting element located within a container containing the pre-plasma matter;
activating the energy emitting element to create plasma from pre-plasma matter;
delivering plasma matter through the catheter lumen wherein the plasma causes shrinkage of the anatomical lumen.
10. A method of claim 9 , wherein the step of inserting further comprises the energy emitting element is positioned near the proximal end of the catheter.
11. A method of claim 9 , wherein the step of delivering includes the pre-plasma matter in a gaseous state.
12. A method of claim 9 , wherein the step of delivering includes the pre-plasma matter in a liquid state.
13. A method of claim 9 , wherein the step of delivering the pre-plasma matter further comprises delivering the matter through an end hole of the catheter.
14. A method of claim 9 , wherein the step of delivering the pre-plasma matter further comprises delivering the matter through at least one side opening in the catheter.
15. A method of claim 14 , prior to delivering pre-plasma matter, further comprising inserting an occluding ball wire into the catheter lumen.
16. An endoluminal treatment method comprising:
inserting into an anatomical lumen a catheter having at least one energy emitting element near the distal end of the catheter and a catheter lumen; wherein the at least one energy emitting element is comprised of an electroporation electrode or a microwave antenna;
delivering pre-plasma matter through the catheter lumen;
activating the energy emitting element to create plasma from the pre-plasma matter wherein the plasma causes shrinkage of the anatomical lumen.
