CENTER VALLEY, Pa., Oct. 28, 2020 /PRNewswire/ -- Olympus, a global technology leader in designing and delivering innovative solutions for medical and surgical procedures, announced today the commercial launch of HANAROSTENT® Esophagus TTS self-expanding metal stents (SEMS) made by M.I. Tech and distributed exclusively through Olympus in the U.S.

The Through-the-Scope (TTS) esophageal stent, the newest addition to the Olympus self-expanding stent portfolio, helps to achieve luminal patency in a variety of clinical applications and is designed for use in palliative treatment of esophageal stricture and/or trachea-esophageal fistula caused by malignant tumors. The stent offers a fully covered or partially covered option.

"From the first cases in which I've used it, I found the HANAROSTENT Esophagus TTS stent to effectively palliate the symptoms of our patients with advanced esophageal cancer," said Dr. Sandeep Patel, a gastroenterologist at UT Health San Antonio. "The hook-cross nitinol design of the TTS stents allows for accurate and efficient placement with increased patient comfort."
Pre-loaded into the delivery system, the HANAROSTENT Esophagus TTS fits down the working channel of a standard therapeutic gastroscope and is deployed for placement in the esophagus. The hook-and-cross nitinol design, unique to HANAROSTENT products, was designed with patient comfort in mind and enables optimal radial and axial force allowing for the flexibility to conform to a patient's anatomy and precisely target the stricture.

Unlike over-the-wire esophageal stents, the new 10.5F HANAROSTENT Esophagus TTS allows for accurate and easy esophageal stenting under direct endoscopic visualization. Additional benefits of the new esophageal stent include:

Minimized Use of Fluoroscopy: Direct visualization of the lumen allows physicians to place the stent with reduced dependence on fluoroscopy.
Increased Procedural Efficiency: Through-the-Scope application allows for fewer scope/device exchanges, leading to increased efficiency and potential reduction of procedure time.
Unique Wire Structure: Hook-and-cross nitinol design provides optimal radial and axial force aimed to minimize the impact of retrosternal pressure, which can be painful to patients.
Intuitive Delivery System: Long delivery length options, ability to fully recapture stent up to a point-of-no-return, as well as a retrieval lasso for stent repositioning combine to allow for safety and precision of placement for users of all experience levels.
