Cook Medical’s Syfonix® Suction Ureteral Access Sheath

Bloomington, Ind. — Cook Medical today announced the commercial launch of two products from its Urology specialty. The Syfonix® Suction Ureteral Access Sheath and the 7.5 Fr Ascend™ Single-Use Flexible Ureteroscope are available in the United States and Canada.

Syfonix is designed to give physicians fingertip control of suction during ureteroscopic kidney stone management procedures. With inner diameter ranges from 9 Fr to 12 Fr, the sheath establishes a working channel to facilitate the passage of endoscopes and ancillary instruments into the urinary tract. It is a single-use device.

Additionally, the Ascend Single-Use Flexible Ureteroscope is now available in a new 7.5 Fr size in addition to the 8.6 Fr size Cook has been offering. As Cook’s pipeline of products includes more products and more sizes, physicians are empowered to treat patients with more precision.

Cook is proud to be a trusted source for a full line of disposables and the latest laser technology for urological healthcare providers. Having a complete portfolio provides a smoother customer experience for ordering products, especially for customers on contract.

“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 Johan Lowinger, director of global product management for Urology at Cook Medical. “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.”

“Suction sheaths are one of the newest tools urologists have to help ensure patients get stone-free in a minimally invasive manner. Now that we have added Syfonix to our product portfolio, along with continuing to expand our Vision offering with the addition of the Ascend 7.5 Fr Ureteroscope, we’re giving physicians a full line of products to customize their treatment plan to the specific patient they’re treating. Commercializing these products in the US and Canada is an important milestone for Cook as we work alongside our clinical partners to further advance treatments in stone management,” said Shayna Martin, director of sales for Cook Medical’s Urology specialty.
