Advancing structural heart solutions with MP35N® 

Cardiovascular health has never been more critical, with millions of lives depending on the constant advancement of medical technology. Carpenter Technology is at the heart of these innovations, pushing the boundaries of what’s possible with high-performance medical-grade alloys like MP35N. 

The cardiology revolution 

Structural heart solutions have been among the most notable cardiology advancements in recent years and have revolutionized how heart conditions are treated. Structural heart solutions address abnormalities or defects in the structure of the heart with medical interventions and cardiac devices. Transcatheter heart valve procedures are some of the most common — and life-changing. Damaged or diseased heart valves are repaired or replaced in minimally invasive procedures where possible. 

The critical role of specialty alloys 

Biomedical implants and surgical instruments for cardiology applications must meet exceedingly stringent performance and quality standards — understandably. Premium materials are indispensable in structural heart applications, laying the foundation for superior implants and instrumentation. Specialty alloys are engineered to provide precise mechanical properties — strength, durability, and ductility — in addition to biocompatibility and radiopacity to satisfy critical design criteria in intricate, small dimensions. 

Introducing MP35N 

Carpenter Technology’s MP35N is a game-changer in the world of cardiology. A nonmagnetic, nickel-cobalt-chromium-molybdenum alloy, MP35N is used in the construction of heart valve frames for transcatheter heart valve systems. This next-gen alloy has a unique combination of properties that are key to elevating structural heart solutions to new heights: 

  • High strength: MP35N has unmatched radial strength and ultra-high tensile strength (up to 300 ksi). This strength enhances the performance and longevity of the implants, ensuring heart valves function optimally for years to come.
  • Open cell geometry: MP35’s strength supports the intricate open cell geometries critical for cardiovascular devices. Open cell geometries enhance the hemodynamics, or flow of blood, through the valve.
  • Good ductility: Heart valves must withstand the repetitive motion of the heart contracting and relaxing. MP35N’s ductility allows heart valve frames to flex without breaking.
  • Excellent resistance to corrosion, sulfidation, high-temperature oxidation, and hydrogen embrittlement: MP35N is virtually immune to general, crevice, and stress corrosion in the extreme conditions within the heart.
  • Radiopacity: MP35N is radiopaque, allowing for easy visualization during implantation and ensuring precise placement. 

MP35N consistently outperforms competing materials used for heart valve frames, providing cardiac device designers with a clear choice for the best alloy selection. The same exceptional properties that make MP35N ideal for structural heart solutions extend to other medical applications — orthopedics, dental, and beyond. Regardless of application, MP35N facilitates minimally invasive surgeries, enhances biocompatibility, and improves patient experiences and outcomes. 

The future of cardiology and specialty alloys 

As the structural heart market continues to grow at an impressive 11% CAGR, the role of differentiated alloys like MP35N becomes even more critical. These materials enable device design challenges to be met head-on, facilitating leaps in cardiac care and more lives saved and improved. With superior high-cycle fatigue properties, MP35N cardiovascular devices can last up to 25 years, compared to the expected lifespan of 1–15 years for conventional materials. 

The revolution in cardiology is in full swing, and Carpenter Technology’s MP35N is at the fore. As we look to the future, we anticipate further innovations in cardiology, driven by the powerful capabilities of specialty alloys.
