Methods, apparatuses, and computer programs for processing pulmonary vein computed tomography images
Patent number: 11869208Abstract: The present disclosure relates to methods, apparatuses, and computer programs for processing computed tomography images. Precise segmentation of the left atrium (LA) in computed tomography (CT) images constitutes a crucial preparatory step for catheter ablation in atrial fibrillation (AF).

The deep learning provides an efficient and accurate way for automatic contouring and LA volume calculation based on the construction of the 3D LA geometry. Non-pulmonary vein (NPV) trigger has been reported as an important predictor of recurrence post atrial fibrillation (AF) ablation. Elimination of NPV triggers can reduce the post-ablation AF recurrence. The deep learning was applied in pre-ablation pulmonary vein computed tomography (PVCT) geometric slices to create a prediction model for NPV triggers in patients with paroxysmal atrial fibrillation (PAF).Type: GrantFiled: March 15, 2021Date of Patent: January 9, 2024Assignees: TAIPEI VETERANS GENERAL HOSPITAL, National Yang Ming Chiao Tung UniversityInventors: Horng-Shing Lu, Chih-Min Liu, Shih-Lin Chang, Shih-Ann Chen, Yenn-Jiang Lin, Hung-Hsun Chen, Wei-Shiang Chen -

Patent number: 11612750Abstract: Systems, methods, and devices for automatic generation of a stimulation therapy that mimics electrographic activity in the brain at natural seizure termination define a stimulation therapy to be generated by an implanted component of a medical device system and delivered to a subject through identifying data characterizing a patient's seizures, especially at termination. A machine learning model identifies the seizures or seizure types from which to establish a canonical seizure or seizure type, and an algorithm translates the canonical seizure or seizure type into data that can be used to characterize a stimulation therapy. The systems, methods, and devices, include those configured to deliver the stimulation therapy that emulates the canonical seizure or seizure type when the seizure is detected, with the aim of terminating the seizure sooner than it would terminate without intervention.Type: GrantFiled: February 27, 2020Date of Patent: March 28, 2023Assignee: NeuroPace, Inc.Inventor: Beata Jarosiewicz

Patent number: 11607568Abstract: Apparatus and methods for deactivating bronchial nerves extending along the secondary bronchial branches of a mammalian subject to treat asthma and related conditions. An ultrasonic transducer (11) is inserted into the bronchus as, for example, by advancing the distal end of a catheter (10) bearing the transducer into the secondary bronchial section to be treated. The ultrasonic transducer emits circumferential ultrasound so as to heat tissues throughout circular impact volume (13) as, for example, at least about 1 cm3 encompassing the bronchus to a temperature sufficient to inactivate nerve conduction but insufficient to cause rapid ablation or necrosis of the tissues. The treatment can be performed without locating or focusing on individual bronchial nerves. The apparatus and methods utilized for lung tumor ablation.Type: GrantFiled: June 17, 2021Date of Patent: March 21, 2023Assignee: AERWAVE MEDICAL, INC.Inventors: Reinhard J.

Patent number: 11576721Abstract: Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.Type: GrantFiled: July 27, 2020Date of Patent: February 14, 2023Assignee: SYMAP MEDICAL (SUZHOU), LIMITEDInventor: Jie Wang

Patent number: 11564704Abstract: In an energy treatment system, a processor temporally detects an electrical property value of an ultrasonic transducer, holds a temporary peak value of the electrical property value, detects an impedance value between the probe electrode and the jaw electrode, and compares the electrical property value and the temporary peak value to determine whether a predetermined condition is satisfied, and whether the impedance value exceeds a predetermined threshold. In response to determining that the electric property value satisfies the predetermined condition and the impedance value is larger than the predetermined threshold, the processor performs at least one of: (i) stopping and (ii) decreasing output from the first power supply, and notifying the determination result.Type: GrantFiled: April 19, 2019Date of Patent: January 31, 2023Assignee: OLYMPUS CORPORATIONInventor: Minoru Kawasaki
