Robinson v. Davol, Inc., No. 17-2068 (7th Cir. 2019)Annotate this Case
Bard manufactures a surgical patch, consisting of two pieces of mesh that surround a flexible plastic ring. During a hernia repair, the patch is folded to fit through a small incision, then the plastic ring springs back into its original shape and flattens the mesh against the abdominal wall. Bard recalled several versions of the patch in 2005-2006 following reports that the plastic ring was defective. Sometimes the ring broke, exposing a sharp edge that could perforate the patient’s intestines. Other times the ring caused the patch to bend and warp, exposing the patch’s adhesive to a patient’s viscera. Before the recall, Bowersock underwent hernia repair surgery, involving a Bard patch. Roughly one year later, she died of complications arising from an abdominal-wall abscess. Her estate sued. Unlike defective patches in other injured patients, Bowersock’s patch did not adhere to her bowel or perforate her organs. Plaintiff's expert tried to present a new theory of causation: the patch had “buckled,” forming a stiff edge that rubbed against and imperceptibly perforated her internal organs. The court excluded that testimony, finding the “buckling” theory not sufficiently reliable. The Seventh Circuit affirmed summary judgment for the defense. The novel theory of causation was not peer-reviewed, professionally presented, consistent with Bowersock’s medical records or autopsy, or substantiated by other cases.
