Abstract

A system including or receiving information regarding the geometry of a patient can be used to identify possible or appropriate instruments for a patient. Instruments can include pacing and defibrillation leads. Information regarding the patient can include target location size, bifurcation angles, and tortuosity of a path. Information regarding the instrument can include diameter, shape, stiffness, and/or other handling characteristics. The information can be used to identify or rank instruments.

5. The method of claim 3, wherein the navigation score is related to a ratio between a determined tortuosity of the path to the target location and a determined ability of the lead to move along the determined tortuosity of the path.

6. The method of claim 3, wherein the stability score is a relative measurement of an ability of the lead to remain stable at the target location based on at least one of a bifurcation angle of a vessel at the target location, a determined tortuosity of the path to the target location, a lead shape, and a tightness of a fit of the lead at the target location.

7. The method of claim 3, wherein the at least one lead includes a plurality of leads;

wherein the lead catalogue includes lead physical data for each lead of the plurality of leads;

wherein the at least one score includes a lead score for each lead of the plurality of leads that is based on all of the fit score, the navigation score, and the stability score.

8. The method of claim 7, further comprising:

displaying the lead score for each lead of the plurality of leads.

9. The method of claim 8, further comprising:

weighting each of the fit score, the navigation score, and the stability score;

wherein the lead score is based on the weighting of each of the fit score, the navigation score, and the stability score.

10. The method of claim 8, further comprising:

determining a delivery system score for each lead of the plurality of leads;

displaying the determined delivery system score.

11. The method of claim 7, wherein lead score includes a summation of all of the fit score, the navigation score, and the stability score to suggest an optimal at least one lead.

4. A method to assist in identifying at least one of a lead or a delivery system of the lead to a target location, comprising:

recalling with a processor system a lead catalogue of the at least one lead and related lead physical data;

recalling with the processor system image data analysis to assist in determining the at least one score;

wherein the recalled image data analysis is based on image data acquired of a subject at the target location;

wherein the recalled image data includes at least a three-dimensional reconstruction of the target location and at least one geometrical measurement of the target location;

wherein the fit score is related to a ratio of a diameter of the at least one lead recalled from the lead catalogue and the at least one geometrical measurement of the target location.

12. A method to assist in identifying at least one of a lead or a delivery system of the lead to a target location, comprising:
