Device Use

VariSoft is an infusion set used with Tandem insulin pumps for the subcutaneous infusion of insulin in the treatment of diabetes. With an insertion angle between 20-45°, the infusion set allows users to choose their most comfortable insertion angle. It is often preferred by users who are thin or who have scar tissue or limiting potential insertion sites. This product is delivered sterile and ready for use. 

Reason for Recall

Unomedical A/S is recalling certain VariSoft Infusion Sets because there is a risk the connector may detach from the infusion set which will disrupt the delivery of the insulin to the patient. If this occurs, insulin may continue to flow through the tubing that is now disconnected from the patient and the insulin pump would not recognize an infusion set problem and would not alert users. 

The defect reported was caused by damage to the connector piece during manufacturing, resulting in the connector becoming detached more easily from the insulin set than expected. Disconnections occurring during sleep, or when otherwise not detected, may lead to hyperglycemia unless it is noticed and reconnected promptly. 

There is a chance of death or life-threatening harm to individual patients using devices from these lots, requiring professional medical intervention.

There has been 1 reported injury. There have been no reports of death.

The following lot numbers are in the scope of this recall: 5388367; 5388357; 5388371; 5388362; 5388368; 5388366; 5388372; 5388376
