During processing of this complaint, attempts were made to obtain complete event, patient and device information.
Date of event has been estimated.
The device was not returned as it was reportedly discarded.

This is a personal preference/opinion of the physician and not a quality issue with respect to manufacture, design or labeling with the product.
There is no indication of product deficiency or product quality issue with respect to design, manufacture or labeling.
The additional devices are being filed under separate medwatch reports.
