Assurity MRI™ Pacemaker

This device is commercially available in select international markets.

Flexibility and Effectiveness to Fit How You Live

• MRI compatible
• Smooth, curved shape
• Enhanced battery longevity
• Daily wireless monitoring between office visits

The Assurity MRI™ Pacemaker is a size and shape that allows your doctor to make a small incision during the implantation procedure. This pacemaker also requires a smaller pocket under the skin of your chest during implantation. 

Equipped with the ability to connect wirelessly to Merlin.net™ Patient Care Network, the Assurity MRI pacemaker communicates important information about your device to your hospital or clinic for your doctor to review. This means you may need to visit your doctor less often.

With the Assurity MRI pacemaker, you can receive magnetic resonance imaging (MRI) scans under certain parameters.

Benefits

• MRI compatible (capable of going through an MRI scanner)
• Requires small incision size for greater comfort
• Potentially extended replacement time because of battery longevity*
• Capable of identifying quick changes in your condition and alerting your doctor 

*Actual battery life depends on how frequently your device sends electrical signals to your heart, and whether it is a single- or dual-chamber device.

Risks

• A small number of patients develop complications from the operation to implant the pacemaker and the leads in the body. These can include the following complications, which can usually be corrected or cured:
  • Infection
  • A reaction to a drug used during surgery
  • Blood loss
  • Damage to a blood vessel, the heart wall or other organ
• After the surgery, you may feel some discomfort or feel tired, but these feelings only last a short time. Some patients, however, may continue to feel a bit uncomfortable in the area where the pacemaker was implanted.
• Modern pacemakers have many safety features. Sometimes a pacemaker may not act properly because it is being affected by outside sources of electromagnetic energy.
• It is also possible for the tip of the lead to shift in the heart so that the pulse is no longer effective. 
• Very rarely, the device may slip out of the “pocket” in the chest.
• Finally, remember these are man-made devices. It is important to monitor the device regularly with follow-up visits as often as your doctor recommends.
• Contact your doctor if:
  • You notice you are tired, short of breath or your heart rate is changing
  • You notice the wound is red, hot, swollen, more painful or beginning to drain fluid
  • Symptoms you had before the pacemaker was implanted seem to return
