Medical system for therapy adjustment

Abstract

Methods and systems for seamless adjustment of treatment are disclosed. A determination can be made as to whether to intervene with a patient's treatment based on data obtained from implantable electrodes and / or non-implantable electrodes. The data from non-implantable electrodes have a correction factor applied to adjust for less accuracy compared to data acquired from implantable electrodes.

Description

[0001]This application claims the benefit of U.S. Patent Application No. 62 / 663,055, filed Apr. 26, 2018, which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present disclosure relates to a medical system, and, more particularly, to a medical system configured to determine whether to intervene with a patient's treatment.BACKGROUND[0003]Chronic heart failure (CHF) is a serious condition that occurs when a heart is unable to consistently pump blood at an adequate rate. To improve the ability of the heart to efficiently pump blood, CHF patients may require an implantable medical device (IMD). IMDs such as implantable cardioverter defibrillators (ICDs) or pacemakers are capable of delivering cardiac resynchronization therapy for improving a CHF patient's heart function. Despite using IMDs to improve heart function, CHF patients may progressively deteriorate, as evidenced by weight gain, change in blood pressure, malaise, fatigue, swelling in legs and feet,...

AI Technical Summary

Benefits of technology

The patent describes a system for managing therapy delivered to patients with heart failure. The system includes an implantable medical device with electrodes to monitor signals from inside the patient's body and a wearable device with electrodes to monitor signals from the surface of the patient's body. The system also has an input / output device to receive data from both devices. The system analyzes the data collected from the implant and the surface device and compares it to pre-defined thresholds to identify potential heart failure worsening events. This information is then used to adjust the patient's therapy to manage heart failure.

Problems solved by technology

Despite using IMDs to improve heart function, CHF patients may progressively deteriorate, as evidenced by weight gain, change in blood pressure, malaise, fatigue, swelling in legs and feet, fainting, and / or palpitations.
