Nationwide Recall of Power Packs used in Insulin Pumps

July 2006 : Fishers, Indiana -- Disetronic Medical Systems Inc. (Disetronic) of Fishers, IN announced a voluntary nationwide recall of the Disetronic D-TRONplus Power Packs, that power the D-TRONplus Insulin Pump. There is the real potential that the power pack could shut down the D-TRONplus Insulin Pump without any warning. If a shut down occurs, insulin delivery is interrupted. An interruption in insulin delivery may lead to uncontrolled diabetes mellitus, resulting in hyperglycemia, which may lead to serious patient injury and/or death. This is an Urgent Device Correction notification to health care professionals and their patients not requiring product removal at this time.

The abrupt shutdown of the D-TRONplus insulin pump is due to a change in the battery design by its manufacturer. As a result, the pump does not have enough time to recognize a decrease in the power supply, which causes the pump to shut down before the audible and vibrating low power alarms are triggered.

Until further notice all pump users must put a new power pack into their insulin pump every two weeks to prevent their pump from turning off without any warning. It is important this two week period not be extended. Disetronic and their distributors will supply power packs free of charge by UPS next day shipment to all D-TRONplus users until corrective actions have been implemented. Every user will receive a power pack together with detailed instructions.

Disetronic and their distributors will also provide every user with a new power pack every two weeks. Distribution of these power packs will begin on Thursday, July 13, 2006.

This is a temporary fix to the power pack problem until adequate supplies of the corrected battery can be obtained. We will update all users when the problem is resolved. Disetronic has tested the replacement design being shipped and we have data to verify a two week use period in the pumps without failure.
