Royer v. Catholic Medical Center
Facts
Ira Royer underwent total knee replacement surgery at Catholic Medical Center in 1991, and a prosthetic knee provided by CMC was implanted as part of the procedure. In 1993, doctors determined that the prosthesis was defective, and Royer underwent a second surgery to remove it and insert another prosthesis. After initially suing the alleged manufacturers, the plaintiffs sued CMC, alleging strict liability for supplying a design-defective prosthesis and asserting a derivative loss of consortium claim. The pleadings also showed that Royer was billed for numerous hospital and medical services in addition to the prosthesis.
Issue
Whether a health care provider that supplies a defective prosthesis during the course of medical treatment is a "seller" or an entity "engaged in the business of selling" prosthetic devices for purposes of strict products liability under Restatement (Second) of Torts section 402A. Put differently, the question was whether CMC's furnishing of the prosthesis was a product sale or merely incidental to the provision of professional medical services.
Rule
In New Hampshire, strict products liability under Restatement (Second) of Torts section 402A applies only when the defendant is engaged in the business of selling the product at issue. Where a health care provider, in the course of rendering health care services, supplies a prosthetic device to be implanted into a patient, the provider is not engaged in the business of selling prostheses and is therefore not subject to strict products liability on that basis.
