KORA™ 250 Pacemaker

Kora™ 250 is world's smallest full-body MRI conditional dual-chamber pacemaker, designed to improve patient outcome while driving efficiency in practice. With 12 years longevity in only 8 cc, Kora™ pacemaker family has minimized sizes with no compromise on longevity. 1

Kora™ 250 is built on the heritage of the Reply platform. The Reply™ pacemaker platform has been proven in practice.

Reply™ pacemakers:

- 99.96% cumulative survival 6 years after implantation.
