Marshfield Clinic has become the first in Wisconsin and among the earliest adopters nationwide to use the new Medtronic OmniaSecure Implantable Cardioverter-Defibrillator (ICD) lead to treat dangerous heart arrhythmias. This new technology allows for a less invasive procedure to correct heart rhythm issues and deliver cardiac resynchronization therapy.
Why it matters
This new ICD lead technology represents a significant advancement in cardiac care, allowing for a simpler and less traumatic procedure to treat heart rhythm disorders and heart failure. As an early adopter, Marshfield Clinic is positioning itself at the forefront of innovative cardiac treatments in Wisconsin.
The details
Marshfield Clinic performed the first implant in Wisconsin of the Medtronic OmniaSecure, the world's smallest ICD lead, in January. This new lead allows for 'Single-Lead cardiac resynchronization' to treat heart failure, rather than the traditional approach requiring two or three leads. The procedure was performed by Electrophysiologist Dr. Weijia Wang, who said the new technology means less trauma to vessels during implantation, quicker recovery, and reduced long-term maintenance issues for patients.
- Marshfield Clinic performed the first implant in Wisconsin of the Medtronic OmniaSecure ICD lead in January 2026.
- Medtronic launched the OmniaSecure ICD lead commercially in the United States on January 8, 2026.
