Publication number: 20230233243Abstract: Systems and methods for controllable delivery of pressurized refrigerant to a medical device, such as a cryoablation catheter. In some examples, a delivery system includes a tank holding the pressurized refrigerant, an electrical heater arranged to heat the tank, and an electronic controller connected to regulate the heater based on input signals received from a plurality of sensors including a temperature sensor in thermal contact with the exterior surface of the tank and a pressure sensor for measuring pressure in the refrigerant-delivery line connecting the tank to the medical device. In operation, the electronic controller processes the input signals by comparing values of at least some of the input signals with respective threshold values and uses logic operations configured for combined processing of two or more of the input signals to decide when to switch the heater between an ON state and an OFF state.Type: ApplicationFiled: January 25, 2023Publication date: July 27, 2023Inventors: Wing-Choi Ma, Nicholas Ruchti, Nicholas L.

Publication number: 20210369393Abstract: Novel tools and techniques are provided for implementing intelligent assistance (“IA”) ecosystem, and, in some cases, for implementing extended reality (“XR”) for cardiac arrhythmia procedures. In various embodiments, a computing system might receive device data associated with a device(s) configured to perform a cardiac arrhythmia procedure to provide effective heart rhythm, might receive imaging data associated with an imaging device(s) configured to generate images of a portion(s) of a patient. The computing system might analyze the received device data and imaging data (collectively “received data”), might map the received data to a 3D or 4D representation of the portion(s) of the patient based on the analysis, and might generate and present (using a user experience (“UX”) device) one or more XR images or experiences based on the mapping.Type: ApplicationFiled: May 28, 2021Publication date: December 2, 2021Inventors: Peter N.

Patent number: 10470880Abstract: A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.Type: GrantFiled: October 14, 2015Date of Patent: November 12, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.
