Novel Biocompatible Ta-Nb-Ti Alloys, Method for Preparing the Same, and Uses Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes new biocompatible alloys made from tantalum (Ta), niobium (Nb), and titanium (Ti), optionally including small amounts of other metals or compounds. These alloys, and methods for their preparation, offer significant improvements for medical use, particularly for implantable devices such as joint prostheses. The alloys are specifically designed to be highly compatible with human tissues, to reduce inflammation, resist bacterial infection, and prevent fibrosis and loosening of prostheses. The patent details both the material compositions and methods for making and applying these alloys as coatings or bulk materials in medical devices.

Use CasesContent extracted from patent full text and abstract with AI.

• Hip and knee joint replacements (endoprostheses) that are more resistant to infection and loosening
• Dental implants with superior tissue integration and reduced inflammation
• Coatings for bone screws, bone plates, or other orthopedic fixation devices to improve biocompatibility and reduce infection risk
• Medical tools or containers requiring anti-bacterial and anti-inflammatory surfaces
• Medical device components with improved resistance to fibrotic scarring, such as vascular stents or catheters
• Treatment of bone damage and prevention of prosthesis loosening in orthopedic surgeries
• Personalized or complex-shaped implantable devices manufactured via additive techniques using the alloys

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduced inflammatory response compared to standard implant materials (e.g., titanium alloys or cobalt-chrome alloys)
• Strong anti-bacterial properties, reducing the risk of infection post-implantation
• Anti-fibrotic effect, helping to prevent scarring and fibrous tissue buildup around the implant
• Reduction or prevention of prosthesis loosening, increasing implant lifespan and reducing revision surgeries
• High biocompatibility, leading to better tissue integration and less risk of implant rejection
• Flexibility in composition allows for tailoring mechanical properties and biological effects to specific applications
• Can be used as both a bulk material and as a thin coating, expanding application versatility
• Production methods compatible with modern manufacturing, including additive (3D printing) and coating technologies
