Connecticut Patent of the Month – August 2024
Spine Wave, Inc. has pioneered an innovative approach to enhancing medical implants through advanced surface texturing. Their cutting-edge technology focuses on improving osseointegration, the process where living bone integrates with an implant, by refining the surface topography of implants. This breakthrough involves a meticulously designed textured tissue contact surface that incorporates both macroscale and microscale features, along with intricate nanostructures.
The process begins with creating a roughened surface on the implant using nanosecond pulsed lasers. This stage establishes a foundation of macro and micro projections and recesses, crucial for initial bone contact. Following this, femtosecond pulsed lasers are employed to introduce nanostructures onto the surface. These nanostructures, characterized by elongated waves and polygonal shapes, further refine the texture without disrupting the underlying macro and micro structures.
This dual-laser approach allows for a precise control over the surface’s texture, enhancing the implant’s ability to promote bone growth. For instance, the elongated waves and polygonal structures provide an optimal scaffold for bone cells to adhere and proliferate, potentially leading to better integration and stability of the implant. The unique combination of roughened macrostructures with intricate nanoscale features is designed to surpass the capabilities of traditional surface treatments.
The texturing technique is applicable to a range of implants, including spinal interbody fusion devices, knee and hip prostheses, and dental implants. By optimizing the implant surface with this advanced technology, Spine Wave is setting a new standard for implant integration and longevity, addressing one of the significant challenges in implant-based medical treatments.
