From the background information supplied by the inventors, news correspondents obtained the following quote: “Non-invasive percutaneous implantation of cardiac devices poses certain challenges to physicians. As opposed to surgically invasive procedures, such as, for example, open heart surgery, physicians performing non-invasive cardiac implantation procedures have a limited field of view and are generally limited to guidance during the procedure using images generated by two-dimensional (2D) imaging modalities (e.g., ultrasound, fluoroscopy, etc.). Because physicians are typically limited to 2D imaging during the performance of a procedure, proper periprocedural planning and evaluation is required to accurately assess and determine, for example, the size of certain anatomical structures and the type(s) and/or size(s) of devices to be used during the procedure (e.g., catheters).
“As with in-procedure guidance, however, conventional periprocedural planning technology has generally been based on imaging platforms and modalities that employ 2D imaging. Accordingly, like the implantation procedure itself, periprocedural planning for such procedures poses challenges to physicians due to the inherent limitations of the conventional 2D imaging that is used.
“Accordingly, there is a need for a periprocedural planning method and system that minimizes and/or eliminates one or more of the above-identified deficiencies in conventional periprocedural planning methodologies/techniques.”
Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’ summary information for this patent: “According to one embodiment, a method for selecting a medical device for use in the performance of a medical procedure is provided. The method comprises acquiring image data relating to an anatomical region of interest of a patient’s body, generating a multi-dimensional depiction of the anatomical region of interest using the acquired image data, defining a plurality of points relative to the multi-dimensional depiction, determining one or more measurements based on the defined plurality of points, and selecting a medical device to be used based on the determined measurements.
“According to another embodiment, a non-transitory, computer-readable storage medium storing instructions thereon is provided. The stored instructions are such that when they are executed by one or more electronic processors, the one or more processors are caused to carry out the method of: acquiring image data relating to an anatomical region of interest of a patient’s body; generating a multi-dimensional depiction of the anatomical region of interest using the acquired image data; defining a plurality of points relative to the multi-dimensional depiction; determining one or more measurements based on the defined plurality of points; and selecting a medical device to be used based on the determined measurements.
“According to yet another embodiment, a system for selecting a medical device of use in a medical procedure is provided. The system comprises an electronic processor and an electronic memory device electrically coupled to the electronic processor and having instructions stored therein. The processor is configured to access the memory device and execute the instructions stored therein such that it is operable to acquire image data relating to an anatomical region of interest of a patient’s body, generate a multi-dimensional depiction of the anatomical region of interest using the acquired image data, define a plurality of points relative to the multi-dimensional depiction, determine one or more measurements based on the defined plurality of points, and select a medical device to be used based on the determined measurements.”
