HugeMed Single-use Ureteral Access Sheath is a single-use device used together with a URS for RIRS. It establishes a flexible and stable pathway in the complex urinary anatomy to facilitate multiple instrument entries. Clinically, it broadens indications, improves single-session stone-free rate (SFR), shortens operative time, lowers intrarenal pressure and temperature, and enhances visualization and irrigation efficiency.

Slimmer for Smoother Access

Specifications: the Single-use Ureteral Access Sheath is available in working lengths of 40/45/50/55 cm and diameters of 8.5/10.5, 9/11, 10/12, 11/13, and 12/14 Fr, yielding 20 flexible combinations that cover needs from ultra-slim access to general negative-pressure aspiration.

For traditional non-suction UAS, the recommended safety rule is RESD ≤ 0.75. Benefiting from active suction that improves outflow and intrarenal pressure control, the Single-use Ureteral Access Sheath allows usage up to RESD ≤ 0.85. In particular, the combination of the world’s first 6.3/3.6Fr URS launched by HugeMed and the world’s first 8.5/10.5 Fr Single-use Ureteral Access Sheath achieves RESD = 0.741, forming a Slim Combo of “ultra-slim URS + ultra-slim suction UAS” that not only raises the successful access rate but also reaches narrower, deeper calyces to tackle challenging stones.

Design details that boost operation efficiency

Material and design highlights of the Single-use Ureteral Access Sheath include: a Slider Valve for fine control of suction power, enabling effective intrarenal pressure management while improving efficiency; a high-elastic Soft Silicon Case compatible with all HugeMed flexible ureteroscopes; The sheath’s Beveled Edge design and Tapered Dilator tip design can reduce insertion trauma; the Stainless-Steel Flat Coil reinforced shaft balances flexibility with structural strength; and a Hydrophilic Coating with Depth Mark for smoother access and more precise positioning.
