## Facts

- Andrina Hansen underwent ulcer surgery in March 1991, during which a physician placed a central venous catheter in her jugular vein connected to IV tubing and connectors made by Baxter.
- Baxter sold two connector designs: a friction-fit (“luer slip”) connector and a more secure luer-lock connector with a threaded locking mechanism.
- Hansen’s central line used a friction-fit connector; the IV tubing detached, causing an air embolism that led to brain damage and paralysis. She died a little more than four years later.
- The estate alleged Baxter knew friction-fit connectors posed a disconnection risk in central lines, knew luer-lock connectors were safer for that use, and failed to distinguish or direct use adequately.
- The estate initially sued medical providers, later added product-liability claims against Baxter, and settled with the medical defendants for $2,880,000.
- At trial against Baxter, the case went to the jury on products liability; the jury returned a general verdict for the estate and awarded $18,047,000, later reduced by setoff for settlements.
- The appellate court held the verdict could be sustained on design defect but not on failure to warn; it applied a full settlement setoff and otherwise left the general verdict intact.

## Issues

1. Whether the general verdict against Baxter could be sustained on a design-defect theory under Illinois consumer-expectation and/or risk-utility standards.
2. Whether the verdict could be sustained on a failure-to-warn theory based on an asserted duty to warn the medical profession about risks of using friction-fit connectors in central lines.
3. Whether the judgment was properly reduced by a setoff equal to the full amount of the prior settlements with the medical defendants.

## Decision

- The Illinois Supreme Court affirmed the appellate court’s judgment as modified.
- The Court held the evidence was sufficient to sustain liability on a design-defect theory under Illinois law.
- The Court agreed the verdict could not be upheld on a failure-to-warn theory.
- Because the jury returned a general verdict and the design-defect theory was supported, the verdict stood despite the failure-to-warn deficiency.
- The Court approved reducing the judgment by the full amount of the settlements.

## Legal Principles

- In Illinois, a product may be found defectively designed under either the consumer-expectation test or the risk-utility test; proof satisfying either may support a verdict.
- Evidence of a feasible, safer alternative design within the manufacturer’s own product line, coupled with serious foreseeable harm, can support a finding of unreasonable danger under risk-utility analysis.
- Under the general verdict rule, where multiple theories are submitted and the verdict is general, the judgment will be affirmed if at least one theory is legally and factually supported and no special interrogatories require a contrary result.
- Failure-to-warn liability in a medical-device setting requires proof of an actionable duty to warn the appropriate medical users and proximate causation linking any warning inadequacy to the injury.
- Settlement amounts paid by other defendants may be credited as a setoff against the judgment to prevent double recovery.

## Conclusion

The court upheld a substantial products-liability judgment against Baxter because the evidence supported design-defect liability for using friction-fit IV connectors in high-risk central-line applications, while rejecting failure-to-warn as an independent basis for liability and applying a full setoff for prior medical-defendant settlements.
