Accent MRI™ Pacemaker

This device is commercially available for use in select international markets.

Everything and MRI

AccentMRI_hero700x227.jpg

The Accent MRI pacemaker, with the Tendril MRI lead, is an MRI conditional system, offering safe performance of a full-body MRI scan on the patient using a 1.5 T (Tesla) field-strength MRI scanner.1 An optional, easy-to-use hand-held unit (SJM MRI Activator™ device) can be applied to enable and disable pre-programmed MRI settings, which is designed to simplify workflow and increase clinic efficiency. The Accent MRI pacemaker is the first MRI conditional pacemaker to offer the option of wireless telemetry for streamlined patient management.

1. MRI conditional pacemaker system; an MRI conditional pacing system is conditionally safe for use in the MRI environment when used according to the instructions in this manual. See the St. Jude Medical MRI Procedure Information document prior to performing an MRI scan.

State-of-the-Art

The state-of-the-art device features:

  • InvisiLink™ Wireless Telemetry or inductive remote follow-up utilising a wand, in conjunction with the Merlin@home™ transmitter and Merlin.net™ Patient Care Network (PCN), allows for daily remote monitoring and follow-up.
  • AT/AF Alerts can be programmed to notify patients and/or their clinics when a programmed AT/AF threshold or continuous episode duration has been exceeded, or when a high ventricular rate accompanies the AT/AF episode.
  • A suite of features—complete automaticity (atrial and ventricular), Ventricular Intrinsic Preference (VIP™) technology, QuickOpt™ timing cycle optimisation, the AF Suppression™ algorithm and SenseAbility™ technology—is designed to deliver optimal therapy for patients at implant and throughout their lives.
  • Industry-leading longevity offers 9,1 years of service life,2 which is supported by a 7-year warranty.3

Safe

The Accent MRI™ pacemaker has been designed and tested for safe performance of a full-body MRI scan, without zone restrictions, using a 1,5 T (Tesla) field-strength MRI scanner.1 The MRI conditional device:

  • Allows a maximum whole body averaged specific absorption rate (SAR) of 4 watts per kilogram (W/kg) for high image resolution.
  • Must be used in conjunction with an MRI lead from St. Jude Medical.

Simplified

An optional, easy-to-use handheld device (SJM MRI Activator™ device) can be used to program the device to pre-approved MRI settings pre- and post-MRI scan, decreasing the number of workflow steps and increasing clinic efficiency.

 

1. The St. Jude Medical™ MRI conditional pacing system can be scanned in patients under the following conditions: horizontal closed bore clinical scanner working in the Normal Operating Mode or First Level Controlled Operating Mode; static magnetic field strength of 1,5 Tesla (T) only; maximum gradient slew rate of 200 T/m/s per axis. See the MRI Procedure Information document for additional details before performing an MRI scan.
2. Model 2224 (dual-chamber device with wireless telemetry); A,V = 2,5 V @ 0,4 ms; 500 ohms; 100% DDD pacing @ 60 bpm; AutoCapture™ Pacing System OFF; SEGMs ON
3. Terms and conditions apply; refer to the warranty for details.
