Abstract
The present invention relates to systems and methods for estimating prosthetic valve expansion diameter, and in particular, for system and methods for analyzing images acquired during prosthetic valve expansion, to identify structural components of the valve, determine dimensions thereof, and estimate at least one outer diameter of the prosthetic valve, and potentially a plurality of outer diameter along different axial positions of the prosthetic valve.
Claims20
A computer system for assisting a clinician during performance of a procedure to implant a prosthetic device in a subject, comprising:
- control circuitry;
- and
- memory communicatively coupled to the control circuitry and storing executable instructions that, when executed by the control circuitry, cause the computer system to perform operations comprising:
- during performance of the procedure,
- receiving images, acquired by an imaging device, that include visual representations of a portion of the subject's interior anatomy and the prosthetic device positioned within the subject;
- analyzing the received images to determine information regarding one or more characteristics or positions of the prosthetic device, wherein the analyzing includes identifying a constant-length component of the prosthetic device in the received images and estimating a measurement of characteristic of the prosthetic device that changes during performance of the procedure based at least in part on a length of the constant-length component of the prosthetic device, and the determined information is based on the estimated measurement;
- and
- displaying a user interface, including concurrently presenting visual representations of the portion of the subject's interior anatomy, the prosthetic device positioned within the subject, and the determined information.
A computer-readable storage medium storing executable instructions that, when executed by control circuitry of a computer system, cause the computer system to perform operations comprising:
- during performance of a procedure to implant a prosthetic device in a subject,
- receiving images, acquired by an imaging device, that include visual representations of a portion of the subject's interior anatomy and the prosthetic device positioned within the subject;
- analyzing the received images to determine information regarding one or more characteristics or positions of the prosthetic device, wherein the analyzing includes identifying a constant-length component of the prosthetic device in the received images and estimating a measurement of characteristic of the prosthetic device that changes during performance of the procedure based at least in part on a length of the constant-length component of the prosthetic device, and the determined information is based on the estimated measurement;
- and
- displaying a user interface, including concurrently presenting visual representations of the portion of the subject's interior anatomy, the prosthetic device positioned within the subject, and the determined information.
A computer-implemented method of providing assistance to a clinician while performing a procedure to implant a prosthetic device in a subject, comprising:
- while the clinician is performing the procedure to implant the prosthetic device in the subject,
- receiving images, acquired by an imaging device, that include visual representations of a portion of the subject's interior anatomy and the prosthetic device positioned within the subject;
- analyzing the received images to determine information regarding one or more characteristics or positions of the prosthetic device, wherein the analyzing includes identifying a constant-length component of the prosthetic device in the received images and estimating a measurement of characteristic of the prosthetic device that changes during performance of the procedure based at least in part on a length of the constant-length component of the prosthetic device, and the determined information is based on the estimated measurement;
- and
- displaying a user interface, including concurrently presenting visual representations of the portion of the subject's interior anatomy, the prosthetic device positioned within the subject, and the determined information.
