Boston Science China market pushes six innovative ureteral stents

Urinary calculi is a general term for kidney, ureter, bladder and urethra stones. It is one of the most common urological diseases. The global prevalence is 1% to 5%, and the number of male patients is about 4 to 5 times that of females. Currently, about 90% of patients will choose to treat urinary calculi with minimally invasive surgery. The ureteral stent is mainly used to relieve ureteral obstruction, maintain ureteral drainage, reduce urinary extravasation, and promote damage repair of ureteral mucosa.

The new Boston Scientific product uses its exclusive patented breakthrough innovation, PercuflexTM, which is biocompatible and biocompatible with traditional ureteral stent materials such as silicone and polyurethane. Sexual advantages are significant: traditional ureteral stents have a residence period of 90 days to half a year, while Boston Scientific PercuflexTM material stents can be retained for up to 365 days in the human body.

In addition to the application of PercuflexTM materials, this new ureteral stent product has also been designed with a number of technological innovations to ease the patient's ease of operation while reducing pain for patients. The tapered tip design makes it easier for the stent to pass through the ureteral orifice; while reducing the overall diameter of the stent, the diameter of the stent lumen is enlarged, and the discomfort of the stent in the body is reduced, thereby achieving better drainage effect. In addition, a number of tick marks on the body of the stent help the doctor to locate more easily and accurately when placing the stent.

Among the six new products, PolarisTM Loop is the star of Boston's scientific urinary ureteral stent . It uses an industry-leading coextrusion process that combines dual materials of different hardnesses to achieve a smooth transition from hard to soft on a bracket to accommodate different anatomical structures of the human body. Application requirements. In the upper part of the kidney and the upper ureter, the shaft of the stent is hard, which provides good structural support and the coil has a high retention force. In the lower part of the ureter and the end of the bladder, the shaft of the stent is soft, which can effectively alleviate the patient's discomfort. In addition, the breakthrough bladder double-loop design reduces the amount of material entering the bladder by 69% compared to conventional stents. When the bladder is filled, the light bladder ring floats in the renal pelvis, significantly reducing the material's contact with the sensitive bladder triangle. Alleviate the suffering of the patient.

Several other stent products introduced at the same time have their own characteristics to meet a variety of clinical applications. PolarisTM Ultra uses a co-extrusion process to meet the different requirements of the ureter to bladder for stent material hardness; ContourTM uses PercuflexTM soft material to soften at body temperature to improve patient tolerance to indwelling stents; PercuflexTM Plus uses PercuflexTM The material's rugged stent, high-strength material and smooth surface help the stent pass through the narrow area; PercuflexTM is a rigid ureteral stent that is radiopaque and helps doctors to observe under the microscope; these stents are for doctors and The patient provided a rich postoperative recovery plan for urinary calculi.

"The introduction of the six ureteral stents marks the determination of Boston's scientific urinary stone management business to continue to grow in China and continue to deepen the market." Mr. Wang Xin, vice president of science and general manager of China, said, "The company has been in March last year. Established the Department of Urinary and Women's Health in China, and has launched nearly 20 new urinary products. This year, under the guidance of Boston's scientific “Innovation Shockwave” strategy, we will continue to focus on introducing innovative products in the Chinese market. Doctors and patients bring safer, more effective medical solutions.
