Systems and methods for selecting, activating, or selecting and activating transducers
Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.
ATRIAL STRETCH MEASUREMENT FOR ATRIAL FIBRILLATION PREVENTION
A stretch-measurement probe includes an elongate outer sleeve, expansion feature associated with a distal portion of the outer sleeve, and an elongate inner rod disposed at least partially within the outer sleeve. The expansion feature is configured to allow a longitudinal distance between a proximal end of the outer sleeve and the distal end of the outer sleeve to be varied.
INTRACARDIAC PRESSURE SENSOR WITH CLIP STRUCTURE
The present technology relates to intracardiac pressure monitoring devices, and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include a pressure sensor configured to reside within a first chamber of a heart of a patient, and a pressure transmission element configured to extend from the first chamber through a septal wall to a second chamber of the heart of the patient. When the device is implanted in the patient's heart, the pressure transmission element is configured to transmit pressure from the second chamber to the pressure sensor residing within the first chamber.

SYSTEMS AND METHODS FOR OPTIMIZING IMPLANTABLE MEDICAL DEVICE CHARACTERISTICS USING DATA STRUCTURES AND GRAPHICAL REPRESENTATIONS
In some examples, a computing apparatus may determine information corresponding to a data structure and indicating delays associated with an atrium lead, a left ventricle (LV) lead, and a right ventricle (RV) lead based on one or more input variables. The computing apparatus may determine a plurality of individualized characteristics based on the information corresponding to the data structure. The computing apparatus may receive, from the plurality of measurement electrodes, a plurality of second sets of electrical measurements indicating second electrical signals applied to the patient's heart based on the plurality of individualized characteristics. The computing apparatus may determine cardiac resynchronization index (CRI) values using a first set of electrical measurements (e.g., native measurements) and the plurality of second sets of electrical measurements. The computing apparatus may generate a graphical representation based on a populated data structure and cause display of the graphical representation.
SENSOR INTEGRATION IN CARDIAC IMPLANT DEVICES
A sensor-retention structure includes a sensor-support strut and a means for securing a sensor device to the sensor-support strut. A sensor-support arm can be configured to have disposed thereon an at least partially cylindrical sensor device and be associated with one or more sensor-retention fingers projecting from the sensor-support arm and/or a cage structure configured to be secured to the sensor device.
Impingement detection for implantable medical devices
In some examples, a system may be used for delivering cardiac therapy or cardiac sensing. The system may include an in implantable medical device including a housing configured to be implanted on or within a heart of a patient, a fixation element configured to attach the housing to the heart; and a sensor configured to produce a signal that indicates motion of the implantable medical device. Processing circuitry may be configured to identify one or more impingements between the housing and another structure, such as a tissue of the heart, based on the signal from the sensor and provide an indication of the one or more impingements to a user.
Autonomous implantable and removable cardiac capsule with a swiveling head and a torque limiter
The capsule comprises a tubular body and a front-end unit with an helical screw for anchoring the capsule to a wall of a patient's organ. The front-end unit is mobile in relative axial rotation with respect to the tubular body. A disengageable frictional coupling member allows this relative rotation when, for implantation, the tubular body receives an external rotational stress, and that until a predetermined limit torque triggering the disengagement. At explantation, this disengagement is prevented to allow a joint rotation of the tubular body and of the front-end unit and the unscrewing of the helical screw. It is provided for that purpose two conjugated plates facing each other, with flat surfaces such as circular sectors offset in opposite directions with respect to a radial reference plane, in such a way as to form steps providing an anti-disengagement abutment function.

In another example, the present technology includes systems and methods for detecting tissue changes and reactions in heart tissue during treatment using one or more temperature sensors. In another example, the present technology includes an improved distal tip for use with an intracardiac device. In another example, the present technology includes systems and methods for maintaining an intracardiac device in a desired position within a patient's heart using magnets or ultrasonic phased arrays mounted on the intracardiac device.

In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include an implantable capacitor having a capacitance value that is variable based on the pressure within the patients heart and a sensing circuit configured to measure the capacitance value. The device can also include an implantable inductor and a power circuit configured to wirelessly receive power from an external source via the inductor. When the device is in a first configuration, the capacitor can be electrically coupled to the sensing circuit and the inductor can be electrically coupled to the power circuit. When the device is in a second configuration, the capacitor can be electrically coupled to the inductor to form a resonant circuit.
