Cook Medical commercially launches two new urology products

March 23, 2026 By Skyler Rivera

Cook Medical commercially launched two new urology products, the Syfonix suction ureteral access sheath and the 7.5 Fr Ascend single-use flexible ureteroscope, according to the company.

Syfonix and Ascend are both single-use products used in ureteroscopic kidney stone management procedures and a part of Cook’s larger portfolio of urological disposables.

The Syfonix suction ureteral access sheath is designed to give physicians fingertip control of suction and visibility during surgery while creating a passage channel for endoscopes and ancillary instruments into the urinary tract.

The access sheath has inner diameter ranges from 9 Fr to 12 Fr and features a disposable stone collector intended to collect kidney stone fragments and assist in adjusting negative pressures during the procedure.

Cook’s new Ascend ureteroscope expands its established collection with a new 7.5 Fr size, offering surgeons more surgical tools in different sizes to treat a broader patient population.The ureteroscope was previously available only in 8.6 Fr diameter until today’s commercialization announcement.

Read more on Cook Medical’s recent launch of new endoscopy products.

Ascend includes an ergonomic scope, an easy flip-switch deflection lock and a distal tip that features dual-LED lighting to illuminate the surgical site and adjacent areas.

The ureteroscope also includes an image processor for surgical teams to improve surgical site image quality by fine-tuning color, saturation, brightness and contrast alongside the processor’s proprietary algorithms to enhance images.

“Suction sheaths are a critical part of improving stone management procedures. Syfonix gives physicians seamless control of suction without having to break focus or rely on additional staff,” said Cook Medical director of global product management Johan Lowinger. “With the Syfonix sheath now available with the Ascend 7.5 Fr flexible ureteroscope, we’re excited to offer a solution that reflects direct feedback from the urology community.”

Both Syfonix and Ascend products are now commercially available in the U.S. and Canada.
