Need to know it all about Nitinol? Thanks to materials with memories, many a human heart continues to beat! ASM’s newest e-Newsletter, e-Elastic, captures the latest news and information about these shape memory materials and the professional society dedicated to them – the ASM International Organization on Shape Memory and Superelastic Technologies. learn more > Simulation of stent deployment in a realistic human coronary artery The process of restenosis after a stenting procedure is related to local biomechanical environment. Arterial wall stresses caused by the interaction of the stent with the vascular wall and possibly stress induced stent strut fracture are two important parameters. Finite element method computations were performed to simulate the deployment of a stent inside the reconstructed coronary artery model. learn more > Bone mineral density increase and in-growth around hip implants A recent study found significant acetabular bone loss and a significant relative increase in bone mineral density for total hip arthroplasty for implants using Zimmer’s Trabecular Metal material compared to titanium. learn more > PediaFlow pediatric ventricular assist device A research consortium lead by the University of Pittsburgh receives $4.4 from NIH to develop a pediatric ventricular assist device based on magnetic levitation technology. learn more > ADA Course: Fractographic Analysis of Ceramic Dental Crowns and Bridges The American Dental Association Foundation offers a yearly course on applying fracture analysis techniques to ceramic and composite dental restoration materials. The 3-day course is offered at the Paffenbarger Research Center located at NIST in Gaithersburg, Md. learn more > Quantum dots: The new Swiss Army knife of nanomedicine Proteins are used to surround a quantum dot core with a thin gold shell at a distance of 3 nanometers so that the two components’ optical and electrical fields do not interfere with one another. The nanoparticle device could perform a wide range of medical tasks such as imaging tumors, carrying drugs, and delivering pulses of heat. learn more > Fewer battery replacement surgeries with improved lithium battery technology Enhanced design of EaglePicher’s lithium carbon monofluoride battery includes end-of-life indicator capability, longer life, and telemetry capability. learn more > Tiny silicone cup attaches to eye for improved drug delivery for retinal diseases Tiny silicone cup drug delivery system sealed to the outer surface (episclera) of the eyeball may offer a more effective method for the delivery of medicines for retinal and vitreous diseases. learn more > Total artificial heart supports patients waiting for transplant Originally used as a permanent replacement heart, the Total Artificial Heartby SynCardia is currently approved as a bridge to human heart transplant for patients dying from end-stage biventricular failure. The device provides immediate, safe blood flow of up to 9.5 L/min through both ventricles. learn more > Tumors no match against carbon nanotube and laser beam double-punch Multi-walled carbon nanotubes, when non-invasively exposed to laser-generated near-infrared radiation, respond by vibrating and creating heat. If enough heat is conducted, tumor cells near the tubes begin to shrink and die. learn more > back to top > |
Co-20Cr-15W-10Ni
Materials for Medical Devices > Materials
Co-20Cr-15W-10Ni is more ductile than most other alloys used for cardiovascular applications. It has excellent corrosion resistance “in vivo”. Ductility makes this material suitable to fabricate, among other things, wire suitable for sutures or cerclage for securing bone fragments (F. Reinlander applications). Also suitable for cardiovascular applications such as stents and eyelet markers in porcine bioprosthesis.
