Wearable Defibrillators & Smart Implants: 2026 Cardiac Device Innovations
By Dr. Sarah Mitchell, Respiratory Equipment Specialist · Published 2026-03-08 · 10 min read
From the ZOLL LifeVest to leadless pacemakers and AI-powered ICDs, cardiac device technology is preventing sudden cardiac death like never before.
Wearable Defibrillators
The ZOLL LifeVest provides external defibrillation for patients at temporary risk of sudden cardiac arrest — typically after MI, before ICD implantation, or during cardiomyopathy recovery. The 2026 LifeVest 5000 weighs under 2 lbs and detects arrhythmias with 99.4% accuracy.
Implantable Innovations
- Medtronic Micra AV2 — leadless pacemaker, 16-year battery, transcatheter delivery
- Boston Scientific EMBLEM S-ICD — entirely subcutaneous, no transvenous leads
- Abbott Aveir DR — first dual-chamber leadless pacing system
- AI-enhanced ICDs — fewer inappropriate shocks via machine learning
Respiratory-Cardiac Crossover
Many heart failure patients also need oxygen therapy. Patients with both cardiac devices and oxygen prescriptions should ensure their home concentrators are positioned appropriately and that any travel includes coordination with the cardiology team.
