Laser Cutting Of 304 316l Stainless Steel Capillary Snake Bone Cardiovascular Stent

Laser Cutting Of 304 316l Stainless Steel Capillary Snake Bone Cardiovascular Stent 0

Category	Parameter	Specification / Details
Material Options	Stainless Steel Grades	316L Stainless Steel (Preferred – superior corrosion resistance, biocompatibility) 304 Stainless Steel (Alternative for non-implantable applications)
	Key Properties	High radial strength, good ductility, excellent corrosion resistance, proven biocompatibility
	Material Standards	ASTM F138 (316L), ASTM F899, ISO 5832-1
Base Capillary Tube	Outer Diameter (OD) Range	0.8 mm to 3.0 mm (pre-cutting) – Expands to 1.5 mm to 6.0 mm post-expansion
	Wall Thickness	0.05 mm to 0.15 mm (Ultra-thin wall for low profile)
	Tube Length	10 mm to 200 mm (customizable per stent length requirements)
Stent Design Specifications	Pattern Type	Snake Bone / Serpentine Design: Continuous sinusoidal rings with flexible connectors; Closed-cell: Enhanced scaffolding, lower chronic outward force; Open-cell: Superior flexibility, better side-branch access; Hybrid: Combination patterns for optimized performance
	Strut Thickness	0.05 mm to 0.12 mm (50-120 μm) – Thin struts for reduced profile and improved healing
	Strut Width	0.06 mm to 0.15 mm (60-150 μm)
	Stent Length	8 mm to 80 mm (Customizable per application)
	Expanded Diameter	1.5 mm to 6.0 mm (dependent on design and post-processing)
	Aspect Ratio (Diameter/Length)	Customizable per clinical requirements
Laser Cutting Specifications	Laser Type	Femtosecond Laser: Ultra-short pulses, minimal HAZ, superior edge quality; Fiber Laser: High precision, cost-effective for production
	Minimum Feature Size	0.02 mm (20 μm) achievable
	Cutting Tolerance	±0.005 mm to ±0.010 mm
	Heat-Affected Zone (HAZ)	< 0.005 mm (femtosecond laser) – Preserves material properties
	Edge Quality	Smooth, burr-free, minimal dross
Post-Processing	Electropolishing	Removes micro-burrs, smooths strut edges, reduces surface roughness to Ra ≤ 0.05 μm; Essential for biocompatibility and fatigue resistance
	Passivation	ASTM A967 – Enhances corrosion resistance
	Heat Treatment	Stress relief annealing to restore ductility and eliminate residual stresses from laser cutting
	Surface Finish (Final)	Ra ≤ 0.1 μm (mirror-like finish)
Mechanical Properties	Radial Strength	Sufficient to withstand vessel recoil; customizable via strut geometry and thickness
	Longitudinal Flexibility	High – snake bone designs provide excellent conformability to tortuous anatomy
	Elastic Recoil	< 5% (for balloon-expandable designs)
	Fatigue Resistance	Meets ASTM F2477 requirements for 400 million cycles (10-year equivalent)
	Radial Force	Customizable per application; higher for peripheral, lower for coronary
Performance Characteristics	Crimped Profile	0.8 mm to 1.5 mm (dependent on stent design and wall thickness) – Low profile for delivery through small vessels
	Expansion Ratio	1.5:1 to 3:1 (crimped to expanded diameter)
	Foreshortening	< 10% (for optimized designs)
	Side-Branch Access	Open-cell designs provide excellent access
	MRI Compatibility	MR Conditional (non-ferromagnetic)
Quality & Compliance	Dimensional Inspection	High-magnification optical measurement, vision systems, micro-CT scanning for 3D geometry verification
	Mechanical Testing	Radial force testing, crush resistance, 3-point bend flexibility, fatigue testing per ASTM F2477
	Material Certification	Mill Test Certificate (MTC) with lot traceability; ISO 5832-1 compliance
	Biocompatibility	ISO 10993-1 compliant (Cytotoxicity, Sensitization, Irritation, Systemic Toxicity, Hemocompatibility)
	Cleanliness	Cleaned to meet implantable device cleanliness standards
	Quality Standards	Manufactured under ISO 13485 (Medical Devices) quality management system
	Regulatory Support	Supports FDA 510(k), PMA, and CE MDR submissions with full device history records (DHR)
Sterilization & Packaging	Sterilization Method	Gamma Irradiation (preferred for stainless steel stents), Ethylene Oxide (ETO) (alternative)
	Sterility Assurance Level (SAL)	10⁻⁶
	Packaging	Individual sterile packaging within hoop or protective tube; Tyvek®/blister tray systems
	Shelf Life	Typically 2-3 years (validated per ISO 11607)
Production Details	Lead Time (Prototype)	10-20 business days (design dependent)
	Lead Time (Production)	3-6 weeks (volume dependent)
	File Formats Accepted	STEP, IGES, DWG, DXF, PDF (detailed 2D flat pattern and 3D stent geometry)
Special Notes	Design Customization	Pattern geometry, strut thickness, length, diameter fully customizable per customer specifications
	Drug-Eluting Capability	Can serve as platform for drug-eluting coating applications (e.g., sirolimus, everolimus)
	Radiopacity	316L stainless steel provides inherent radiopacity for fluoroscopic visualization
