ABOUT SURGSCI SURGSCI MEDICAL LTD. SurgSci focuses on core technologies and innovative applications in minimally invasive surgery. The company has established three major technology platforms: medical-grade metal materials, polymer materials, and artificial intelligence algorithms. These platforms support two primary product lines— surgical instruments and surgical consumables. SurgSci has successfully overcome key technical challenges in high-performance medical titanium alloys, advanced piezoelectric ceramic materials, and AI-driven intelligent ultrasonic high-frequency surgical systems. As...

NanoPath® Ureteral Stent System More than drainage under compression When tumor or fibrosis continuously compresses the ureter, treatment must establish and maintain a luminal channel across the lesion. Clinical problem chain Persistent extrinsic force Luminal narrowing Restricted urine flow Renal function at risk Burden of repeated exchange Priority clinical scenarios 1 Ureteral obstruction caused by malignant extrinsic compression Especially when lesion-level patency must be maintained Retroperitoneal fibrosis Persistent fibrotic encasement and ureteral compression Severe fibrotic stricture...

NanoPath® Ureteral Stent System Thermo-responsive support at the lesion After low-profile delivery across the stricture, warm saline triggers expansion and the dense spring provides continuous support along the lesion. Assess and locate Guidewireaccess Define etiology, Establish a safe length and location delivery route Deliver and position Span the entire stricture Thermal expansion Warm saline triggers shaping Imaging confirmation Confirm coverage and end positions Four engineering features address fourclinical needs Nitinol shape memory Expansion triggered by >55°C saline Low-profile delivery,...

NanoPath® Ureteral Stent System Three layers. One clinical goal. Mechanics, structure and surface — all for one clinical goal: sustained patency under compression. Sustained radial support Patency under malignant compression requires durable support The all-metal nitinol spring spans the full lesion. It maintains a patent lumen even under malignant compression or severe fibrotic stricture. Dense inter-coil structure Smaller gaps reduce tissue entry into the lumen Denser coil spacing delivers more support points and smaller inter-coil gaps, reducing tissue protrusion into the stent. Low-nickel-release...

NanoPath® Ureteral Stent System A proven platform for high compression Mature thermo-responsive nitinol coil technology, designed around sustained compression, support continuity and long-term implantation. Mature thermal pathway NanoPath product focus Nitinol shape-memory coil Sustained-compression settings Temperature-triggered shaping Focus on malignant compression and severe fibrosis Warm-water expansion, coldwater softening Dense inter-coil structure Controlled placement and removal Improves support continuity and reduces tissue entry Segmental metal support All-metal spring Spans a localized...

NanoPath® Ureteral Stent System Precise sizing to support the lesion Integrate etiology, stricture length, delivery route and follow-up into one treatment pathway. Pre-op assessment Placement essentials Follow-up priorities Define etiology, site and lesion length Ensure the stent fully spans the stricture Monitor hydronephrosis and renal function Assess guidewire passage and ipsilateral renal function Confirm proximal and distal coverage Monitor infection, hematuria and pain Control infection; complete urine culture and imaging Trigger shaping with >55°C saline Watch for migration, encrustation...
