Carelink is a United States(US) based remote monitoring system used by physicians or clinics to communicate with patients’ implanted heart devices using a small monitor. This potentially reduces the number of times a patient would travel to a clinic for a device check.

“Enrolled” is the total number of US patients registered in the Carelink system.

“Active” and “Cumulative Follow-Up Months” are based on the status recorded in Carelink.

“Normal Battery Depletions” is the number observed in the Carelink system.
