The US Food and Drug Administration put its seal of approval on Quill Medical’s new means of suturing wounds.

The OK is the latest in a series of regulatory endorsements for Quill’s technology of so-called self-anchoring sutures that does away with the need to use knots as part of wound closings. The sutures were approved in Europe last year, and the FDA has sanctioned Quill products for use in cosmetic surgery.

The new product will be marketed under the name Contour Thread.

The clinical trial that led to the FDA approval was performed at Duke University Medical Center. The sutures were used to close Caesarean section incisions for 195 patients.

The suture was invented by Gregory Ruff, Quill’s chairman, who was a member of the Department of Surgery at Duke for 17 years.
