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.
Claims21
A computer-based method of planning a catheter-based intervention, the method comprising:
- obtaining, by a computing device, a model of an anatomical region of interest;
- determining, by the computing device, an entry in the anatomical region of interest;
- determining, by the computing device, a target in the anatomical region of interest;
- determining, by the computing device, a trajectory from the entry to the target, the trajectory comprising a sequence of a plurality of trajectory segments, wherein determining the trajectory comprises determining a first trajectory segment of the plurality of trajectory segments comprising:
- obtaining a planned position for an implantable device in the anatomical region of interest, wherein the planned position defines a deployment axis of the implantable device;
- and
- determining the first trajectory segment as a line segment that connects a first point on a central axis of a first feature of the anatomical region of interest with a second point on the deployment axis and that passes through a geometric center point of a second feature of the anatomical region of interest;
- and
- selecting, by the computing device, a catheter from a plurality of catheters based on the catheter being able to achieve the trajectory within at least a threshold.

A computing device comprising:
- a memory;
- and
- a processor configured to:
- obtain a model of an anatomical region of interest;
- determine an entry in the anatomical region of interest;
- determine a target in the anatomical region of interest;
- determine a trajectory from the entry to the target, the trajectory comprising a sequence of a plurality of trajectory segments, wherein to determine the trajectory comprises to determine a first trajectory segment of the plurality of trajectory segments comprising to:
- obtain a planned position for an implantable device in the anatomical region of interest, wherein the planned position defines a deployment axis of the implantable device;
- and
- determine the first trajectory segment as a line segment that connects a first point on a central axis of a first feature of the anatomical region of interest with a second point on the deployment axis and that passes through a geometric center point of a second feature of the anatomical region of interest;
- and
- select a catheter from a plurality of catheters based on the catheter being able to achieve the trajectory within at least a threshold.

A non-transitory computer-readable medium having computer-executable instructions stored thereon, which, when executed by a processor of a computing device, cause the computing device to perform a method of planning a catheter-based intervention, the method comprising:
- obtaining a model of an anatomical region of interest;
- determining an entry in the anatomical region of interest;
- determining a target in the anatomical region of interest;
- determining a trajectory from the entry to the target, the trajectory comprising a sequence of a plurality of trajectory segments, wherein determining the trajectory comprises determining a first trajectory segment of the plurality of trajectory segments comprising:
- obtaining a planned position for an implantable device in the anatomical region of interest, wherein the planned position defines a deployment axis of the implantable device;
- and
- determining the first trajectory segment as a line segment that connects a first point on a central axis of a first feature of the anatomical region of interest with a second point on the deployment axis and that passes through a geometric center point of a second feature of the anatomical region of interest;
- and
- selecting a catheter from a plurality of catheters based on the catheter being able to achieve the trajectory within at least a threshold.
