1.What makes Nitinol ideal for heart valve frames?
Nitinol's superelasticity and shape memory allow frames to compress for catheter delivery and self-expand reliably at body temperature, while offering superior fatigue life for lifelong cardiac cycling.
2.Is this NiTi tubing medical grade and biocompatible?
Yes, our DLX tube meets medical grade standards (e.g., ASTM F2063) with proven biocompatibility, low thrombogenicity, and excellent corrosion resistance for permanent cardiovascular implants.
3.What are the advantages over stainless steel or cobalt-chromium for valve stents?
Nitinol provides greater flexibility, higher recoverable strain, and better fatigue resistance, reducing trauma during deployment and improving long-term performance in dynamic heart valve applications.
4.Can this tubing be customized for specific heart valve designs?
Absolutely – we offer tailored dimensions, Af temperatures, and surface finishes to optimize radial force and deployment characteristics for transcatheter valve frames.
