Described herein is an implantable medical device that includes a body having one or more ultrasonic transducers configured to receive ultrasonic waves and convert energy from the ultrasonic waves into an electrical energy, two or more electrodes in electrical communication with the ultrasonic transducer, and a clip attached to the body that is configured to at least partially surround a nerve and/or a filamentous tissue and position the two or more electrodes in electrical communication with the nerve. In certain examples, the implantable medical device includes two ultrasonic transducers with orthogonal polarization axes. Also described herein are methods for treating incontinence in a subject by converting energy from ultrasonic waves into an electrical energy that powers a full implanted medical device, and electrically stimulating a tibial nerve, a pudendal nerve, or a sacral nerve, or a branch thereof, using the fully implanted medical device.

A medical device includes a motion sensor configured to sense a motion signal. The medical device includes a control circuit configured to determine at least one ventricular event metric from the motion signal sensed over multiple of atrial cycles, determine that the ventricular event metric meets atrioventricular block criteria and generate an output in response to determining the atrioventricular block.

Systems and methods for treating gastroesophageal reflux disease (GERD) includes minimally invasively implanting a stimulating device in a patient's esophagus in the region proximate the lower esophageal sphincter (LES). The patient is provided with a questionnaire related to his disease via an online service. The questionnaire is accessed on a mobile device, such as a cell phone, or on a computer with network access. The data from the sensors and the answers from the questionnaire are analyzed together by a health care provider using the online service. The data and answers are used to program the stimulating device, via the mobile device or computer, to optimize treatment.

The present disclosure relates generally to pacing of cardiac tissue, and more particularly to adjusting delivery of His bundle or bundle branch pacing in a cardiac pacing system to achieve synchronized ventricular activation. A leadless pacing device (LPD) may include a plurality of electrodes comprising a bundle pacing electrode leadlessly connected to the housing, which may be implanted proximate to or in the His bundle or bundle branch of the patient's heart. An electrical pulse generator may generate and deliver electrical His-bundle or bundle-branch stimulation pulses using the bundle pacing electrode based on sensing one or both of an atrial event and a ventricular event. The LPD may receive communication from another implantable device, such as a subcutaneously implanted device, and deliver His-bundle or bundle-branch pacing in response to the communication.

In an illustrative embodiment, systems and apparatus for limiting acceleration of medical equipment dropped to a location of an emergency medical event include one or more protection elements for protecting the medical equipment against impact forces that may damage the equipment. The protection elements may include one or more elements configured to reduce acceleration of the medical equipment while dropping to the location. The protection elements may include one or more elements configured to absorb impact forces to reduce the forces realized by the medical equipment. The medical equipment may be dropped to the location by an unmanned aerial vehicle.

A system and method for facilitating remote care management involving a patient having an implantable medical device (IMD). Upon establishing a remote care session between a patient controller device and a clinician programmer, wherein the clinician and the patient are remotely located with respect to each other, input from the patient or the clinician may be received via a user interface control associated with a particular functionality or aspect of the remote care session, including audiovisual (AV) communications, remote therapy programming, and related context. Responsive to the user input, a dialog interface is effectuated at one of the patient controller device and/or the clinician programmer. A user characterization label is received via the dialog interface from the user, wherein the user characterization label is indicative of a subjective assessment of the particular functionality of the remote care session, which may be used in generating user-labeled data pertaining thereto.

A method includes receiving first information regarding a pose of a structure in a first time period. The structure is configured to be inserted into a body portion of a recipient. The first information includes at least one of: a first estimate of the pose of the structure in the first time period, and a first measurement set including one or more first measurement values. At least some of the one or more first measurement values are generated using a plurality of sensors distributed along the structure. The one or more first measurement values are indicative of the pose of the structure in the first time period. The method further includes generating a second estimate of the pose of the structure using at least the first information and a probabilistic model of the structure and/or the body portion.

A communication platform at least partially implements secure communications between a medical device and a trusted authority (TA) service provider. The secure communications prevent access to the secure communications by the communication platform while permitting access to the secure communications at the medical device and/or at the trusted authority service provider.

In some variations provided herein, a system for deep brain stimulation includes an implantable device that acquire and store neural activity signal records and apply electrical stimulation. The system further includes a personal controller device that establishes a first wireless connection to the implantable device. The personal controller device transmits power to the implantable device, and the implantable device transmits neural activity signal records to the personal controller device over the first wireless connection. The system further includes a clinician programmer device that receive the neural activity signal records from the implantable device by establishing a second wireless connection based on activation of the first wireless connection. The clinician programmer device sets one or more stimulation parameters based on the neural activity signal records.

A method is provided for precision dosing of electrical stimulation of the brain. The method includes determining a location of each voxel of a plurality of voxels in a reference frame of an electro-stimulation device including a plurality of electrodes positioned on a head of a subject. The method also includes obtaining measurements that indicate a tissue type at each voxel inside the head of the subject based on an imaging device. The method also includes determining, with a processor, a value of one or more parameters of the electro-stimulation device based on the tissue type measurements at each voxel such that the electro-stimulation device is configured to generate a value of one or more parameters of an electric field at each voxel inside the head of the subject to improve the treatment outcome of the subject.
