913 F. Supp. 2d 370
W.D. Ky.2012Background
- Daltons filed a diversity action against Animas for alleged design and manufacturing defects in the Animas Model 2020 insulin infusion pump and related claims.
- The 2020 Pump automatically delivers insulin and uses a Prime Operation after cartridge changes to remove air, requiring the user to disconnect the tubing during the procedure.
- Mrs. Dalton had used the pump for about a year with no incident until a late-night sequence on April 21, 2008 culminated in an alleged over-infusion.
- According to software logs, Dalton replaced the cartridge and performed the Prime Operation at 10:00 p.m.; alarms later indicated a battery change and a Prime Operation deficiency.
- At approximately 5:10 a.m., an Empty Cartridge Alarm was followed by the infusion of about 125.5 units, which plaintiffs claim caused Mrs. Dalton’s injuries.
- Defendant moved for summary judgment on all claims; the court granted in part and denied in part, preserving certain design-defect theories and related negligence claims.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a manufacturing defect claim survives | Daltons contend a stuck button or similar manufacturing defect caused over-infusion. | Animas argues there is no evidence of a stuck button; speculation cannot support liability. | Stuck-button theory dismissed; no evidence supports manufacturing defect. |
| Whether a prime-limit design defect theory is viable | Prime limit could have prevented over-infusion by limiting insulin during Prime Operation. | No proven alternative design; warnings and training were deemed sufficient. | Prime-limit theory could be feasible; jury could find defect due to lack of such feature. |
| Whether the change-of-battery design defect theory is viable | Battery-change procedure unnecessarily requires Prime Operation, risking misalignment and air ingress. | Prime Operation after battery change protects against air in system; disputed whether necessary. | Disputed issue; summary judgment not appropriate on this theory. |
| Whether negligence and strict liability design claims can proceed together | Design defect supports both theories; both should be viable paths to recovery. | Duplicative theories may confuse the jury; limit to one theory per design defect claim. | Negligence claim remains viable alongside strict liability for design defect; caution against duplicative recovery. |
| Whether KCPA, breach of warranty, loss of consortium, and punitive damages claims survive | KCPA and punitive damages are viable if misrepresentations or malice exist; warranty theories may support recovery. | KCPA claim lacks specific unlawful conduct; punitive damages require malice; warranty scope limited by pump’s warranty. | KCPA and punitive damages dismissed; breach of implied warranty dismissed; loss of consortium remains derivative; warranty claims limited by warranty terms. |
