Cook Medical Expands Percutaneous Stone Extractor Line With Double Product Launch

Cook Medical is giving urologists more stone extraction device options for percutaneous nephrolithotomy (PCNL). The company on Nov. 24 launched the Perc NGage and Perc NCompass nitinol stone extractors, expanding its stone extraction line and complementing the Perc NCircle, a 12-year-old product claimed to be the first nitinol extraction device for percutaneous procedures. 

The two extractors are designed specifically to remove stones and stone fragments when physicians are removing kidney stones percutaneously. The design of the extractors mimics the original NGage and NCompass, which are indicated for ureteroscopic stone removal procedures.

Because every kidney stone is different, the method for extraction varies from stone to stone. The different wire configurations of each extractor are useful in various scenarios. For example, the Perc NGage can grasp and release a stone, while the Perc NCompass has a 16-wire configuration.

“These products were developed for physicians who needed, in PCNL procedures, the same options that they currently have with our ureteroscopy extractors,” said Jean-Marc Creissel, vice president and global leader of Cook Medical’s Urology division. “We are pleased to be able to meet that product need and fill out our percutaneous extraction offering. Now physicians can apply the technology they master to an additional procedure.”

Based in Bloomington, Ind., Cook Medical provides medical devices, biologic materials and cellular therapies for various healthcare segments.
