Abstract

A method for pre-planning and performing a cardiac procedure on a heart includes acquiring an image or map of the heart; displaying the image or map of the heart; marking at least one feature on the image or map; calculating dimensions of the at least one feature; identifying one or more points on or within the heart for treatment; determining paths to the one or more points on or within the heart for treatment; simulating insertion of a sheath into the heart; simulating insertion of a medical device through the sheath and within the heart; verifying that the one or more points on or within the heart can be accessed for treatment; and performing a medical procedure on or within the heart.

Claims

1. A method for pre-planning a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart; and

verifying that the one or more points on or within the heart can be accessed for treatment.

2. A method for developing a plan for a cardiac procedure comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart; and

verifying that the one or more points on or within the heart can be accessed for treatment.

3. A method for pre-planning and performing a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart;

verifying that the one or more points on or within the heart can be accessed for treatment; and

performing a medical procedure on or within the heart.

4. The method according to claim 3, wherein the medical procedure is monitored and guided according to the plan.

5. The method according to claim 4, wherein the medical procedure is monitored and robotically guided according to the plan.

6. A method for developing a plan and performing a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart;

verifying that the one or more points on or within the heart can be accessed for treatment; and

performing a medical procedure on or within the heart.

7. The method according to claim 6, wherein the medical procedure is monitored and guided according to the plan.

8. The method according to claim 7, wherein the medical procedure is monitored and robotically guided according to the plan.

9. A method for simulating a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart; and

verifying that the one or more points on or within the heart can be accessed for treatment.

10. A method for simulating and developing a plan for a cardiac procedure comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart; and

verifying that the one or more points on or within the heart can be accessed for treatment.

11. A method for simulating and performing a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart;

verifying that the one or more points on or within the heart can be accessed for treatment; and

performing a medical procedure on or within the heart.

12. The method according to claim 11, wherein the medical procedure is monitored and guided according to the plan.

13. The method according to claim 12, wherein the medical procedure is monitored and robotically guided according to the plan.

14. A method for simulating a cardiac procedure, developing a plan and performing a cardiac procedure on a heart comprising the steps of:

acquiring an image or map of the heart;

displaying the image or map of the heart;

marking at least one feature on the image or map;

calculating dimensions of the at least one feature;

identifying one or more points on or within the heart for treatment;

determining paths to the one or more points on or within the heart for treatment;

simulating insertion of a sheath into the heart;

simulating insertion of a medical device through the sheath and within the heart;

verifying that the one or more points on or within the heart can be accessed for treatment; and

performing a medical procedure on or within the heart.
