Abstract
Systems and processes for designing and generating personalized surgical implants and devices are described herein. In various embodiments, the process includes generating patient-specific implants with patient-specific surface(s) and/or textures designed for increased osseointegration and improved surgical outcomes. In various embodiments, the process includes extracting patient-specific data with one or more aspects of an anatomical feature, processing the one or more aspects of the anatomical feature to create a non-rigid shape reference, and generating a patient-specific implant or device.
Core Innovation
A medical device production process is described in which a database is populated with a plurality of 2D image packages, patient anatomical representations associated with the 2D image packages, and patient-specific device files associated with the patient anatomical representations. For a particular patient, a particular 2D image package is received, including 2D image files associated with an anatomical feature of that particular patient, and one or more aspects of the anatomical feature are extracted from the particular 2D image package.
The extracted aspects are processed via an artificial intelligence model to create a non-rigid shape reference based upon a plurality of patient anatomical representations and patient-specific device files. The non-rigid shape reference is then used to generate a digital representation of at least one patient-specific device based on the database.
The described workflow supports generating patient-specific devices whose digital representations are derived from AI processing of extracted anatomical feature aspects. The patient-specific device digital representation is generated in association with the non-rigid shape reference and is grounded in stored patient anatomical representations and patient-specific device files that are linked to the 2D image packages.
Claims Coverage
The independent claim is directed to a medical device production process having a database population stage and a patient-specific workflow that extracts anatomical feature aspects from 2D image packages, uses an artificial intelligence model to create a non-rigid shape reference, and generates a digital representation of at least one patient-specific device.
Database with 2D image packages and patient-specific device files
A database is populated with a plurality of 2D image packages of patient-specific anatomy, a plurality of patient anatomical representations associated with the 2D image packages, and a plurality of patient-specific device files associated with the patient anatomical representations.
Extracting aspects from a patient 2D image package for an anatomical feature
A particular 2D image package associated with a particular patient is received, including a series of 2D image files associated with an anatomical feature of the particular patient, and one or more aspects of the anatomical feature are extracted from the particular 2D image package.
AI-created non-rigid shape reference based on representations and device files
The extracted one or more aspects of the anatomical feature are processed via an artificial intelligence model to create a non-rigid shape reference based upon the plurality of patient anatomical representations and patient-specific device files.
Digital representation of patient-specific device generated from non-rigid shape reference
A digital representation of at least one patient-specific device is generated based on the non-rigid shape reference of the anatomical feature of the particular patient and the database.
Patient-specific implant as the patient-specific device
The process further defines that the patient-specific device includes a patient-specific implant.
Patient-specific instrument as the patient-specific device
The process further defines that the patient-specific device includes a patient-specific instrument.
Particular AI model using 3D digital representation and device files
A particular artificial intelligence model is used to generate a digital representation of at least one patient-specific device from a patient's 3D anatomical feature, a plurality of patient-specific device files, and processing aspects of the anatomical feature with the particular AI model.
Outputting a patient-specific device file by compiling multiple device files
The specific artificial intelligence model outputs a patient-specific device file by compiling multiple patient-specific device files.
Across the independent claim and its dependents, the claimed coverage centers on building a database linking 2D image packages, patient anatomical representations, and patient-specific device files; extracting anatomical feature aspects from received 2D images; using an artificial intelligence model to create a non-rigid shape reference; and generating a digital representation of at least one patient-specific device, with dependent claims specifying implant versus instrument, use of a particular AI model with 3D anatomical features, and output of a device file via compilation of multiple device files.
