Claims
- 1. A method for monitoring revascularization treatment provided to tissue comprising the steps of:identifying a location in tissue; positioning a catheter at the location; measuring electrical signals of the tissue in order to establish pre-revascularization data; storing the pre-revascularization data; imparting energy to the tissue with the catheter in order to create a channel in the tissue at the location; measuring electrical signals of the tissue after creation of the channel in order to establish post-revascularization data, and comparing the pre-revascularization data to the post-revascularization data in order to determine successful treatment to the tissue.
- 2. The method according to claim 1, further comprising creating a map based on the pre-revasculatization data.
- 3. The method according to claim 2, further comprising creating another map based on the post-revascularization data.
- 4. The method according to claim 3, wherein the maps are created based on the electrical signals of the tissue.
- 5. The method according to claim 3, wherein the maps are created using ultrasound.
- 6. The method according to claim 1, further comprising storing the post-revascularization data.
- 7. The method according to claim 1, wherein the tissue is heart tissue.
- 8. The method according to claim 7, further comprising measuring electrical signals with the catheter.
- 9. The method according to claim 7, further comprising measuring electrical signals with a surface ECG.
- 10. The method according to claim 7, further comprising navigating the catheter with a position sensor.
- 11. The method according to claim 10, further comprising orienting the catheter at the location.
- 12. The method according to claim 1, wherein the energy is laser energy.
- 13. The method according to claim 1, wherein the energy is RF energy.
- 14. The method according to claim 1, wherein the energy is ultrasound energy.
- 15. The method according to claim 1, wherein the energy is mechanical energy.
