FROM STNG WIRE REPORTS

　A woman who underwent dental implant surgery at a Chicago office is suing the makers of products
used in the surgery, after she learned the products had been recalled and she had contracted Hepatitis C.

　After undergoing a dental implant procedure at the University of Chicago that utilized bone allograft
products, Donna A. Drew was told about the recall and was advised to undergo medical testing,
according to a suit filed in Cook County Circuit Court Friday.

　After undergoing the testing, Drew was diagnosed with Hepatitis C.

　The seven-count suit names Tutogen Medical, Inc., Biomedical Tissue Services, Ltd., Zimmer
Dental, Inc. and Apptec, Inc. - medical companies that were involved in the making of the products.

　Drew accuses the companies of failing to include adequate and sufficient instructions and warnings to
patients that the product could be contaminated. The companies also inadequately designed,
manufactured and tested the product, allowing for contamination, the suit said.

　The suit seeks an amount in excess of the jurisdiction limits, as well as court fees.
