PM1214 NUANCE SR RF; PM1230 and PM2230 NUANCE MRI; PM2214 NUANCE DR RF These low voltage (LV) devices are implantable pacemaker pulse generators, intended to be permanently implanted in the body, that have a power supply and electronic circuits that produce a periodic electrical pulse to stimulate the heart. These devices are used as a substitute for the heart's intrinsic pacing system to correct both intermittent and continuous cardiac rhythm disorders.
New pacemaker firmware was developed to further mitigate the risk of unauthorized access to our pacemakers that utilize radio frequency (RF) communications.
