Medical Device Spring Solutions
Certified to ISO 13485 standards, manufacturing biocompatible, ultra-clean, and high-precision springs for surgical and drug delivery devices.
Medical Device Spring Engineering Standards
Medical device springs require biocompatible metallurgy, microscopic burr-free deburring, tight force tolerance repeatability, and ultrasonic cleanroom packaging. TOSTA specializes in ISO 13485 compliant precision springs for class I, II, and III medical devices, supporting autoclave sterilization and full material bio-compliance documentation (USP Class VI, ISO 10993).
Typical Applications
Auto-Injector & Syringe Pump Springs
Precision calibrated force delivery for single-use auto-injectors, insulin pens, and automated micro-infusion pumps.
Endoscopic & Surgical Instrument Springs
Micro compression and torsion springs for endoscopic graspers, laparoscopic scissors, and surgical staplers.
Orthopedic & Dental Orthodontic Springs
Biocompatible titanium and superelastic NiTi (Nitinol) springs providing gentle, continuous load over wide deflection ranges.
Implantable & Vascular Catheter Guides
Ultra-fine wire micro-coils and radiopaque springs for guidewires, vascular stents, and neurovascular delivery catheters.
Dialysis & Diagnostic Equipment Springs
Electropolished corrosion-proof valve springs and pinch-valve springs for hemodialysis machines and clinical analyzers.
Medical Sensor & Respiratory Device Springs
Low-force tactile feedback springs and diaphragm return springs for medical ventilators and anesthesia delivery systems.
