Block Needle (Plugging Needle): Precision Vascular Occlusion for Minimally Invasive Interventions
Clinical Purpose
Engineered for reliable vessel sealing and targeted tissue occlusion, the Block Needle delivers controlled closure during interventional radiology, biopsy tract sealing, and embolization therapies. It enables physicians to rapidly isolate blood vessels or ducts (e.g., biliary, fallopian tubes) while minimizing collateral tissue damage.
Critical Advantages
Dual-Mode Occlusion
– Sharp-tip penetration: Ultra-bevelled 15° tip for smooth tissue entry.
– Blunt-tip expansion: Deployable micro-plug creates instant 3D occlusion.
Enhanced Safety
– Depth-specific radiopaque markers (every 5mm) under fluoroscopy.
– Torque-control hub prevents accidental over-advancement.
Процедурная эффективность
– 30% faster vessel sealing vs. manual compression.
– Luer-Lock compatibility for simultaneous embolic agent delivery.
Передовое материаловедение
– Core: Medical 304L stainless steel (OD tolerance: ±0.02mm).
– Surface: Hydrophilic polymer coating (contact angle: 18°) reduces friction by 40%.
– Visibility: Distal tungsten tip (20% density) for CT/MRI compatibility + laser-etched echogenic bands for ultrasound guidance.
Приложения
– Biopsy tract closure (liver/kidney)
– Pre-embolization vessel blocking
– Microvascular leakage control in reconstructive surgery
– Non-surgical sterilization procedures
Compliance & Customization
– Sterile EO gamma-packed | ISO 13485 | FDA 21 CFR 880.5570
– Gauge range: 18G–25G | Lengths: 5cm–20cm
– OEM options: Coil-reinforced shafts | Antibacterial coatings
