Brief Summary:
Medtronic is sponsoring the Micra Continued Access (CA) study to provide continued access to the Micra System while the marketing application is under review by the Food and Drug Administration (FDA).

Condition or disease Intervention/treatment Phase
Bradycardia Device: Micra Pacemaker Implant Not Applicable

Detailed Description:
The Micra CA study is a prospective, non-randomized, multi-center, study designed to allow controlled access of the Micra system when used as intended. All subjects enrolled in the Micra CA Study will be prospectively followed from implant, at 6-month intervals until study closure (i.e. FDA approval). Patients with previous or existing inactive implanted cardiac stimulation systems will have additional follow ups.
