Clearance for DNA suture
The US Food and Drug Administration has cleared for marketing in the US the first absorbable polymer suture made from material isolated from bacteria modified by recombinant DNA technology.

.
The TephaFLEX Absorbable Suture, which is made by Tepha of Cambridge, Massachusetts, is the first absorbable polymer suture made from material isolated from bacteria modified by recombinant DNA technology.
Recombinant DNA technology uses living organisms to create chemicals that may be more difficult to produce under standard industrial methods.
‘The TephaFLEX Absorbable Suture is made from material that uses the latest DNA technology,’ said Daniel Schultz, MD, director, Center for Devices and Radiological Health, FDA. ‘This approach could have broader applications for medical devices that use this novel manufacturing technology.’
According to a statement, the FDA based its decision on the company's laboratory and animal testing that examined chemical composition, biological safety and mechanical performance of the polymeric suture. The company provided data to show that the suture could be manufactured in a consistent and safe manner.
FDA reviewed safety and effectiveness information for the device under the de novo petition process. De novo petitions were added under the Food and Drug Administration Modernization Act of 1997 to find a way for novel but less risky products to get to market. As a result of its review, FDA determined that products of this type will be regulated as class II (moderate-risk) devices.
