In June of 2018, the Norwegian Institute of Public Health (NIPH) has published a single technology assessment regarding the MicraTM Transcatheter Pacing System (Micra TPS) - a leadless pacemaker produced by Medtronic to reduce the rate of complications following pacemaker implantations through design and novel technology. The objective of the assessment was to investigate the clinical efficacy, safety and cost effectiveness of Micra TPS in patients indicated for single chamber ventricular pacemaker implantation. The results have shown that the current evidence is not sufficient to prove that the Micra TPS gives less complications than standard pacemakers, also the use of Micra appeared not to be cost-effective.
