  • STIMULATION APPARATUS
    Publication number: 20220176133
    Abstract: A medical apparatus for a patient comprises an external system and an implantable system. The external system is configured to transmit one or more transmission signals, each transmission signal comprising at least power or data. The implantable system is configured to receive the one or more transmission signals from the external system, and to deliver stimulation energy to the patient. Methods of delivering stimulation energy are also provided.
    Type: Application
    Filed: July 23, 2021
    Publication date: June 9, 2022

  • Low energy conversion of ventricular tachycardia in a subcutaneous defibrillator
    Patent number: 10792505
    Abstract: Methods and devices for cardiac therapy. One example provides a subcutaneous anti-tachycardia pacing therapy. Another example provides a subcutaneous low energy cardioversion therapy. Yet another example provides a subcutaneous multiple pulse cardioversion therapy. In various examples, specific steps are taken to ensure synchronization of delivered therapy when provided in response to sensing and analysis of a subcutaneous signal. Some examples use a substernal device instead.

  • Implantable cardiac systems with baseline correction in response to noise detection
    Patent number: 8954136
    Abstract: Implantable cardiac devices and methods of their use. A method of operation in an implantable cardiac device may include steps for characterizing detected events as noise or not noise, identifying a set of consecutive noise events or a threshold quantity of noise events in a set period of time and declaring a noisy series to have occurred. In response to the declaration of a noisy series, the method initiates a baseline correction algorithm. Devices for performing such methods are also disclosed.
