It built OmniaSecure on its reliable SelectSecure Model 3830 pacing lead for catheter delivery. It adds to the wide-ranging Medtronic portfolio of lead solutions for precise delivery and placement. Implantable cardioverter defibrillators (ICDs) provide life-saving cardiac interventions. But Medtronic aims to improve upon one area of weakness: the transvenous leads.

Existing leads with large diameters may increase the potential for downstream complications. Those may inclue venous occlusion or tricuspid valve regurgitation. The medtech giant says OmniaSecure is the world’s smallest defibrillation lead, coming in at 4.7 French, or 1.6mm. That equals about the diameter of graphite in a wooden pencil
