A transient, closed-loop network of wireless, body-integrated devices for autonomous electrotherapy

Area of Science:

• Bioelectronic Engineering
• Biomedical Devices
• Cardiovascular Technology

Background:

• Traditional temporary cardiac pacing relies on percutaneous leads and external wired systems, posing risks of infection, limited mobility, and requiring surgical removal.
• Existing bioresorbable pacemakers still necessitate external wired connections and secondary control mechanisms, limiting their practical application.

Purpose of the Study:

• To introduce a transient, closed-loop system for temporary cardiac pacing that overcomes the limitations of current hardware.
• To develop a wirelessly integrated system for autonomous cardiac rhythm management and cardiopulmonary monitoring.

Main Methods:

• Development of a time-synchronized, wireless network of skin-integrated devices coupled with an advanced bioresorbable pacemaker.
• Implementation of autonomous, rate-adaptive cardiac pacing functionalities.
• Validation of the system in preclinical (rat, canine) and human heart studies.

Main Results:

• Demonstrated successful autonomous and rate-adaptive cardiac pacing capabilities.
• Showcased the system's ability to track cardiopulmonary status and provide multihaptic feedback.
• Established a transient operation with significantly reduced patient burden compared to wired systems.

Conclusions:

• The presented transient closed-loop system offers a novel, wireless solution for temporary cardiac electrotherapy.
• This bioelectronic approach minimizes patient invasiveness and enhances mobility during temporary pacing.
• The study provides an engineering framework for future closed-loop, wirelessly linked bioelectronic therapeutic devices.
