"The therapeutic promise of leadless pacing has been in discussion for the past 40 years. Unfortunately, no one has been able to overcome the technical challenges - until now. Introducing the Nanostim leadless pacemaker - the world's first leadless pacemaker. St. Jude Medical, the company that introduced the world's very first cardiac pacemaker in 1958, has again demonstrated how we transform challenges into healthcare solutions that are revolutionary. The Nanostim leadless pacemaker is small enough to fit entirely inside the right ventricle. And since no lead implant is required, you eliminate the known risks of acute lead dislodgement, lead failure, lead removal, and the hemodynamic impact of the lead crossing the tricuspid valve.
