___ NY3d ___, 2015 NY Slip Op 04786 
The Court of Appeals has just issued this significant opinion reviewing its major precedents concerning the foreign-object rule in medical malpractice cases, arriving at the factors determining when a given object may qualify for the discovery rule codified in CPLR 214-a, and when it must be excluded as a “fixation device.”
Recall that where a med mal action is based on the discovery of a foreign object in the patient’s body, the statute allows for an extension of the limitations period, for a year after the discovery. Excepted from consideration as “foreign objects” are chemical compounds, fixation devices, and prosthetic aids or devices. Defendants will argue for a broad definition of these terms, thus narrowing the category of foreign objects subject to the discovery rule. Plaintiffs, of course, take the opposite tack.
