Abstract
Systems and methods enabling a personalized solution for allowing more efficient access to the carotid artery (or vertebral arteries) m patients needing endovascular/neurointervention procedures using catheter systems.
Core Innovation
The invention provides a method of creating a vasculature model of a patient and evaluating the movement of a modeled catheter through the vasculature model. It obtains a series of 2D images of a volume of the patient, identifies vessel interiors and vessel boundaries of interest, and assembles the identified interiors and boundaries into a 3D assembly representing a patient 3D model of vessels of interest.
The invention further interpolates between adjacent planar slices to create a continuous representation of a vessel interior from one adjacent slice to another. A modeled catheter is introduced into the 3D model, where the modeled catheter is a finite element model representing the physical dimensions and strength parameters of the catheter, and user manipulation of the modeled catheter within the 3D model assesses the viability of movement.
For preparing a patient for recanalization, the same 2D-to-3D vessel modeling and catheter viability assessment are applied during diagnosing and/or preparing a patient. In additional refinements, a mechanical-to-electronic interface and a physical model of proximal ends are used to enable user manipulation via the proximal ends.
Claims Coverage
The independent claims cover four main inventive aspects, each including user-manipulated catheter movement viability assessment within patient-specific 3D vasculature models.
Creating a patient vasculature model from 2D planar slices and enabling catheter movement viability assessment
Obtaining a series of 2D images of a volume of the patient; identifying vessel interiors and vessel boundaries of interest; assembling the vessel interiors and vessel boundaries into a 3D assembly representing a 3D model of vessels of interest; interpolating between adjacent planar slices to create a continuous representation of a vessel interior; introducing a modeled catheter into the 3D model as a finite element model representing physical dimensions and strength parameters; and enabling user manipulation of the modeled catheter within the 3D model to assess the viability of movement.
Preparing for a recanalization procedure using a 3D vessel model and a finite element modeled catheter with user manipulation
Obtaining a series of 2D images of a volume of the patient while diagnosing and/or preparing a patient for a recanalization procedure; identifying vessel interiors and vessel boundaries of interest; assembling the vessel interiors and vessel boundaries into a 3D assembly; interpolating between adjacent planar slices to create a continuous representation of a vessel interior; introducing a modeled catheter into the 3D model as a finite element model representing physical dimensions and strength parameters; and enabling user manipulation of the modeled catheter to assess viability of movement.
Preparing for a recanalization procedure using best-match patient model record retrieval from anatomical measurements
Obtaining a series of 2D images; analyzing a selection of the 2D images to measure a plurality of anatomical features and obtain a series of anatomical measurements; introducing the series of anatomical measurements into a patient vasculature database having a plurality of patient model records; identifying a best match patient model record based on comparison of measured anatomical features; enabling the user to access the corresponding patient 3D model; and, while preparing for the recanalization procedure, enabling user manipulation of the patient 3D model to assess viability of movement of a modeled catheter within the patient 3D model.
Preparing for a recanalization procedure with database matching and user manipulation of the accessed patient 3D model
After accessing the corresponding patient 3D model from the best match patient model record, the user manipulates the patient 3D model to assess viability of movement of a modeled catheter within the patient 3D model.
The independent claims collectively define building a patient-specific 3D vasculature model from 2D planar slices with interpolation, inserting a finite element modeled catheter and enabling user manipulation to assess movement viability, preparing for a recanalization procedure using the same viability assessment during diagnosis/preparation, and selecting a best-match patient model record from a patient vasculature database using measured anatomical features before user manipulation of the accessed patient 3D model.
