Heart Valves
Vascotube produces Nitinol tubing for use in transcatheter aortic valve replacement (TAVR), transcatheter mitral valve replacement (TMVR) and transcatheter tricuspid valve replacement (TTVR). These heart valves require tubing with superelasticity and fatigue resistance, allowing the stent to expand and support the valve for long-term durability.
Peripheral and Neurovascular Stents
For peripheral vascular and neurovascular stents, Vascotube provides biocompatible, fatigue-resistant Nitinol tubing. These stents must withstand repeated cycles of stress while maintaining flexibility and structural integrity, crucial for both arterial support and neurovascular interventions.
Quality is integrated into every step of the manufacturing process. Starting from ingot bars, Vascotube oversees the entire production cycle, ensuring strict adherence to customer specifications and industry standards.
Key Technical Specifications:
- Surface Roughness - Vascotube achieves outer surface roughness values as low as 0.1 μm (Ra) and inner surface roughness as low as 0.2 μm (Ra), critical for the lifecycle of stents and medical devices.
- Concentricity -Tight tolerances of up to 0.01 mm are maintained, ensuring consistent results in high-volume production.
- Wall Tolerances - Vascotube guarantees wall thickness tolerances as narrow as ± 0.0075 mm across entire production batches, impacting the device's fatigue performance and durability.
Vascotube processes not only Nitinol but also other high-performance alloys to meet the diverse needs of the medical device industry. Their portfolio includes:
- Nitinol - Known for its shape memory and superelasticity, Nitinol is the primary material used in cardiovascular and neurovascular stents. Vascotube’s process ensures superior surface quality and concentricity tolerances as tight as 0.01 mm, with wall tolerances as narrow as ±0.0075 mm.
- L-605 and MP35N - These cobalt-chromium alloys are utilized for their high strength, corrosion resistance, and ability to perform in the most demanding environments, including cardiovascular implants.
- Tantalum and Titanium - Known for their biocompatibility and strength-to-weight ratio, these materials are ideal for various implantable devices and vascular implants.
- Magnesium - As a biodegradable material, magnesium is gaining traction in temporary stent applications, where it supports vessels during healing and then safely degrades within the body.
