Medtronic Insulin Pump Lot 8 Infusion Set Problems

Following the Medtronic recall for “Lot 8” Quick-Set infusion sets used with the MiniMed Paradigm insulin pump, it has become clear that the defective sets have caused a number of problems for diabetics. The product liability lawyers at Saiontz & Kirk, P.A. are continuing to review potential Medtronic Lot 8 infusion set lawsuits for individuals hospitalized as a result of their insulin pump delivering too little or too much insulin.

>>PRIOR POST (7/13/2009): Medtronic Lot 8 Infusion Set Recall

Most users were notified by letter earlier his month about the potential Medtronic MiniMed insulin pump problems after a recall notice was issued on July 10. At that time, Medtronic indicated that approximately 2%, or 60,000, of the 3 million “Quick-Set” infusion sets from one lot may be defective. The products can be identified by a lot number on the label starting with “8”, and are commonly referred to as “Lot 8” Medtronic infusion sets. They also contain reference numbers MMT-396, MMT-397, MMT-398 or MMT-399.

The disposable plastic tubes are used to infuse diabetes patients with controlled amounts of insulin from a MiniMed pump. However, the defective Lot 8 sets may not allow the pump to vent air pressure properly, potentially resulting in too much insulin or too little insulin being delivered. This poses a risk of serious injury or death for consumers.

An overdose of insulin can lead to problems like headaches, irregular heartbeat, increased pulse and heart rate, anxiety, increased hunger, sweating, tremors and nausea and can result in death.

An insufficient dose of insulin can result in high blood sugar levels and potentially a diabetic coma (ketoacidosis) or death.

Anyone who suspects that they are suffering from an incorrect dose of insulin should seek medical attention immediately.


If you, a friend or family member have experienced problems with a Medtronic MiniMed insulin pump resulting in serious injury after using recalled Lot 8 infusion sets, financial compensation may be available. Contact the Medtronic infusion set lawyers at Saiontz & Kirk, P.A. to review your potential claim. There are no fees or expenses unless a recovery is obtained.

    I just recently learned that I have ( and have been using!) these infusion sets.For about 2-3 weeks last months, my blood sugar stayed between 300-600 or higher on some days. I had to be treated in the ER as well as several visits to my doctor for many complications. Because of the effects it had on my eyes, I will now have to wear glasses on a regular basis (instead of just for reading). Because of such high levels of ketones in my urine, I developed a boil in my groin area the size of a large pecan; it still has not completely gone away. I am so thankful that I didn’t go into a coma, or die for that matter… my blood sugar levels were so high that my meter couldn’t even read it on numerous occassions. I’m very thankful espically because I have a husband and children ( 8, 10, & 15) to think of. Shame Shame Medtronic!!.

    My ex husband brought my 13 year old son Koby Sumrall in August 2008, to get the medtronic minimed pump, that’s when my HELL started. The first week in Oct. we had to bring him to the ER and he went into a coma, they transferred him to Childrens Hospital in New Orleans and he was there in PICU for almost two weeks, his bloodsuger was over 800 that time. Koby was diagnosed with diabetes at the age of three and from the age of three until he got the pump at age 13, he only had to be in the hospital two times, when he got the pump in Aug. 2008 till the next August 22, 2009, he was in PICU five or six times, thats not including having to take him to the ER every two weeks or so to have his kidneys flushed out. It kills me because I would fuss at him and tell him that he was lying about counting his carbs. I just wish that I would have put him back on the shots or just believed him. Two months after he was put on the pump he started having seizures and it was related to all the problems that he was having with his bloodsuger due to the pump. In the early morning hours of August 22, 2009, my baby slipped into a coma while he was sleeping and died, his bloodsuger level when he died was over 1200. I’m sorry to hear about what you all are going through, I know how you feel. Medtronic will pay for what happened to my baby, I know that it wont bring him back but they need to pay for all the pain that they have caused. They can hire all their high priced attorneys but I have high priced attorneys also, and I also have all of the lot 8 boxes, the used abs the unused ones and the doctors, and the medical examiners reports, the detectives that investigated and much more.

    Does anyone know the expiration date that was on this box. I know it was Lot 8 but not sure of exp date. If anyone could post the oldest expiration date it would greatly help me.

    To all of you who have lost loved ones and have experienced serious complications from the pumps my heart goes out to each of you, I pray that the Lord continue to bless each of you and your families with the strength to continue on. I stumbled on to this website to get reviews regarding the insulin pump. Today I was being encouraged to go that way, but deep in my heart I don’t trust it for the very reasons you have testified of…. thank each of you for sharing your testimonies. I am blessed because of your Christian courage. God Bless and keep each of you.
