Coated ureteral stents feature durable surface hydrophilic coating with strong adhesion. The coating lowers friction for smoother device insertion, cuts procedural deployment difficulty and alleviates patient discomfort.
Thermo-responsive ureteral stents deliver heightened softness and reliable temperature-sensitive performance. They maintain moderate rigidity during intraoperative placement and soften under bodily temperature post-insertion, mitigating foreign-body irritation and boosting patient comfort.
Triangular tube architecture expands the stone drainage gap between the stent and ureteral wall to facilitate clearance of stone fragments and reduce the risk of steinstrasse formation. Rounded vertex transitions minimize post-implant foreign-body sensations. The proprietary dotted surface texture delivers clean, distinct visual markings.
Rounded stent tip finishing reduces insertion resistance. Helically arranged multiple side holes elevate kink resistance and optimize inner-to-outer diameter ratios for superior drainage performance. Full-body radiopacity enables precise intraoperative positioning; blue soft tip options amplify tip X-ray discernibility. Single-open and double-open end configurations are offered to satisfy diverse clinical requirements.
Color-coded pusher tubes are matched with stent specifications of varied sizes, facilitating easy distinction and clinical deployment.
Customizable guidewire selections: stainless steel guidewire, PTFE-coated guidewire, hydrophilic guidewire, zebra guidewire, with comprehensive size coverage.
Securing clamps lock stent placement via multi-groove construction, supporting convenient, flexible operation.
