8/12 - Iradimed Corporation, MRidium 3860+ Infusion Systems equipped with MRidium 1145 Dose Error Reduction System Drug Library Kit: Class I Recall - Potential for Incorrect Recommended Infusion Rate


ISSUE: FDA notified healthcare professionals of a Class I recall of the Iradimed Corporation, MRidium 3860+ Infusion Systems equipped with MRidium 1145 Dose Error Reduction System (DERS) Drug Library Kit. The Dose Error Reduction System (DERS) can potentially give an incorrect recommended value for the pump infusion rate during the initial infusion setup. This is due to a specific key sequence when the override feature of the DERS drug limits is activated. A device malfunction can result in an increased risk of over-infusion or under-infusion if the infusion is started with this rate value. This can cause serious adverse health consequences, including death.

This recall does not affect the following products:

  • MRidium™ 3860+ Infusion Pump used without the DERS (Part No. 1145) Kit
  • MRidium™ 3861 Infusion Pump Channel B accessory.
  • MRidium™ 3865 Infusion Pump Remote Display accessory.
  • None of the MRidium™ 3850 Infusion Pump products (models 3850, 3851, or 3855).

Part number 1145 Lots: 4501,4510, 4538, 4587, 4596, 4675, 4690, 4705, 4738, 4748, 4960, 4970, 5001, 5065, 5104, 6164, 5221, 5240, 5349, 5361, 5517, 5737, 5764, 5881, 6006, 6151, 6170, 6180, 6252, 6470, 6583, 6806, 6881, 6984, and 7213.

These products were manufactured from Oct. 1, 2011 through June 27, 2013 and distributed from Oct. 6, 2011 through June 28, 2013.

BACKGROUND: The MRidium 3860+ Infusion pumps are intended for general hospital or clinical use by medical professionals whenever it is required to infuse patients with fluids and/or medications into the vein (intravenous) or through the artery (intra-arterial) before, during or after Magnetic Resonance Imagining (MRI) scans. The MRidium 1145 Dose Reduction System (DERS) drug library kit is an accessory intended for use with the MRidium 3860+ Infusion Pump System.


RECOMMENDATION: Iradimed Corporation notified its customers by phone and on July 1, 2013 they sent an URGENT MEDICAL DEVICE RECALL NOTICE to all customers. The notice described the product, problem and actions to be taken. Customers were instructed to identify the MRidium 3860+ Infusion Pumps which have the 1145 DERS Library card (AM05) installed. If these are not installed, no further action is required at this time. However, if the DERS Library card is installed, remove the 1145 DERS Library Card from the 3860 Pump using the instructions provided in the URGENT MEDICAL DEVICE RECALL NOTICE.

The product will be repaired (reconditioned) by installing a software upgrade that corrects this problem. The updated software (version 3.5.1) can be seen during the 3860+ Pump's power on cycle.
