Abstract

A method and system are provided that provide feedback regarding lead stability for a candidate target vessel, and provide guidance on a type of lead to be used. The method and system utilize a surgical navigation system and information regarding patient anatomy to predict lead stability within the patient anatomy. The method and system provide patient-specific force measurements for one or more vessels of a patient.

Claims

1. A system for determining a lead placement site within patient anatomy, the system comprising:

at least one processor configured to calculate a lead stability index (LSI) relating to a lead placement site for one or more candidate vessels; and

a display operatively coupled to the at least one processor, wherein the display is configured to show data related to the lead placement site, and wherein the at least one processor is configured to display the data related to the lead placement site on the display as color-coded data.

2. The system of claim 1, wherein the at least one processor is configured to calculate the LSI through the following equation:

3. The system of claim 1, wherein the at least one processor is configured to calculate the LSI through the following equation:

4. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels based on motion and anatomical measurements in each of the one more candidate vessels.

5. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for acceleration experienced by the one or more candidate vessels.

6. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for vessel tortuosity.

7. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for vessel length.

8. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for ostial angle.

9. The system of claim 1, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for (a) acceleration experienced by the one or more candidate vessels, (b) vessel tortuosity, (c) vessel length, and (d) ostial angle.

10. A method for determining a lead placement site within patient anatomy, the method comprising:

calculating a lead stability index (LSI) relating to a lead placement site for one or more candidate vessels; and

displaying data related to the lead placement site, wherein the displaying operation comprises displaying color-coded data related to the one or more candidate vessels.

11. The method of claim 10, wherein the calculating operation comprises calculating the LSI through the following equation:

12. The method of claim 10, wherein the calculating operation comprises calculating the LSI through the following equation:

13. The method of claim 10, wherein the calculating operation comprises accounting for acceleration experienced by the one or more candidate vessels.

14. The method of claim 10, wherein the calculating operation comprises accounting for (a) acceleration experienced by the one or more candidate vessels, (b) vessel tortuosity, (c) vessel length, and (d) ostial angle.

15. A system for determining a lead placement site within patient anatomy, the system comprising:

at least one processor configured to calculate a lead stability index (LSI) relating to a lead placement site for one or more candidate vessels, wherein the at least one processor is configured to calculate the LSI of the one or more candidate vessels, at least in part, by accounting for acceleration experienced by the one or more candidate vessels; and

a display operatively coupled to the at least one processor, wherein the display is configured to show data related to the lead placement site.

16. The system of claim 15, wherein the at least one processor is configured to calculate the LSI through the following equation:

17. The system of claim 15, wherein the at least one processor is configured to calculate the LSI through the following equation:

18. A method for determining a lead placement site within patient anatomy, the method comprising:

calculating a lead stability index (LSI) relating to a lead placement site for one or more candidate vessels, wherein the calculating operation comprises accounting for acceleration experienced by the one or more candidate vessels; and

displaying data related to the lead placement site.

19. The method of claim 18, wherein the calculating operation comprises calculating the LSI through the following equation:

20. The method of claim 18, wherein the calculating operation comprises calculating the LSI through the following equation:
