11471680 · 2022-10-18 · ·

Methods, systems and apparatuses for delivering electrical or other therapy in the vicinity of the eye, comprising eyepieces having a plurality of electrodes that are placed on the eyelid. Some examples are just eyepieces having a periphery that partly surrounds the eye, other examples fully surround the eye or include a temporal portion configured to extend to the temple of the user. Some examples also include a field that covers the eye to take the form of a goggle. Numerous configurations for power supply and therapy output are discussed.

Mitigating false messages and effects thereof in multi-chamber leadless pacemaker systems and other IMD systems

Implantable medical devices (IMDs) described herein, and methods for use therewith described herein, reduce how often an IMD accepts a false message and/or reduce adverse effects of an IMD accepting a false message. Such IMDs can be leadless pacemakers (LPs), or implantable cardio defibrillators (ICDs), but are not limited thereto. Such embodiments can be used help multiple IMDs (e.g., multiple LPs) implanted within a same patient maintain synchronous operation, such as synchronous multi-chamber pacing.

SYSTEMS AND METHODS FOR HEART FAILURE MANAGEMENT

Systems and methods for managing heart failure are described. The system receives physiological information including a first HS signal corresponding to paced ventricular contractions and a second HS signal corresponding to intrinsic ventricular contractions. The system detects worsening heart failure (WHF) using the received physiological information. A signal analyzer circuit can generate a paced HS metric from the first HS signal and a sensed HS metric from the second HS signal, and determine a concordance indicator between the paced and the sensed HS metrics. In response to the detected WHF, the system can use the concordance indicator to generate a therapy adjustment indicator for adjusting electrostimulation therapy, or a worsening cardiac contractility indicator indicating the detected WHF is attributed to degrading myocardial contractility.

FILTERED FEEDTHROUGH ASSEMBLY FOR USE IN IMPLANTABLE MEDICAL DEVICE AND METHOD OF MANUFACTURING THE SAME
20230118734 · 2023-04-20 ·

A method of manufacturing a filtered feedthrough assembly for use with an implantable medical device. The method may include gold brazing an insulator to a flange at first braze joint, and gold brazing a plurality of feedthrough wire to the insulator at second braze joints. The method may further include applying a first non-conductive epoxy to the first braze joint, and applying a second non-conductive epoxy to the second braze joint. The method may further include grit blasting a face of the flange, applying a conductive epoxy to the face of the flange, and attaching an EMI filter to the conductive epoxy such that it is grounded to the flange via the conductive epoxy and not via the first braze joint or the second braze joints.

IMPROVING SPECIFICITY OF NON-PHYSIOLOGICAL SHORT INTERVALS AS A LEAD MONITORING DIAGNOSTIC
20230121385 · 2023-04-20 ·

Methods and systems for diagnosis of lead system anomalies for an implantable medical device. More particularly, the present disclosure relates to prediction and/or detection of a lead system condition by utilizing electrogram (EGM) analysis to identify which non-physiological short interval signals (NPSIs) are more indicative of lead system conditions, including lead failure, than of other causes.

SYSTEMS AND METHODS FOR IMPLANTING A MEDICAL DEVICE USING AN ACTIVE GUIDEWIRE

Systems and methods for implanting a lead. The system includes an active guidewire having proximal and distal ends. The distal end includes a guidewire anchor that is configured to be attached to a target SOL. The active guidewire is configured to be utilized to electrically map the target SOI by at least one of delivering stimulation energy through the active guide wire to the target SOI or sensing an evoked response at the target SOI from the guidewire. The system also includes a lead having a lead body with proximal and distal ends and with a lumen extending between the proximal and distal ends. The distal end of the lead body is configured to receive the proximal end of the active guidewire. The lumen is configured to permit the lead body to be advanced over the active guidewire.

Methods and implantable medical devices for automatic entry to an exposure mode of operation upon exposure to a magnetic disturbance

Implantable medical devices automatically switch from a normal mode of operation to an exposure mode of operation and back to the normal mode of operation. The implantable medical devices may utilize hysteresis timers in order to determine if entry and/or exit criteria for the exposure mode are met. The implantable medical devices may utilize additional considerations for entry to the exposure mode such as a confirmation counter or a moving buffer of sensor values. The implantable medical devices may utilize additional considerations for exiting the exposure mode of operation and returning to the normal mode, such as total time in the exposure mode, patient position, and high voltage source charge time in the case of devices with defibrillation capabilities.

Priority-based medical data management system

Systems and methods for managing medical information storage and transmission are discussed. A data management system may include a receiver circuit to receive information about a physiological event sensed from a patient, and an event prioritizer circuit to assign a priority to the received information. A control circuit may perform data reduction of the received information according to the assigned priority. Data reduction at a higher reduction rate is performed on the received information if a lower priority is assigned than if a higher priority is assigned. The system may include an output circuit to output the received information to a user or a process, or to transmit the received information to an external device, according to the assigned priority.
