Abstract
Systems and methods for planning delivery of an object via a catheter, such as transseptal delivery of a prosthetic mitral valve to a patient's heart are disclosed.
Claims20
A computer-based method of planning a catheter-based intervention, the method comprising:
- obtaining, at a computing device, a model of an anatomical region of interest;
- determining, at the computing device, an entry in the anatomical region of interest;
- determining, at the computing device, a target in the anatomical region of interest;
- determining, at the computing device, a trajectory from the entry to the target, the trajectory comprising a parametric or piecewise parametric curve, a sequence of straight line segments, or a combination of curves and line segments;
- and
- selecting, at the computing device, a catheter from a plurality of catheters,
- wherein selecting the catheter comprises:
- obtaining geometric information of an outer surface and radius of each of the plurality of catheters;
- for each of the plurality of catheters, generating a virtual tube along the trajectory having the corresponding radius;
- for each of the plurality of catheters, registering the corresponding outer surface to the corresponding virtual tube;
- for each of the plurality of catheters, measuring a deviation between the registered corresponding outer surface and the corresponding virtual tube;
- and
- selecting, among the plurality of catheters, the catheter having the smallest deviation between the registered corresponding outer surface and the corresponding virtual tube.
