Maryland Patent of the Month – February 2024

In the ever-evolving landscape of medical technology, Sonavex, Inc. has been granted a patent for an ultrasound-detectable device that promises to redefine the visualization of medical implants within the human body. This invention combines innovative design with advanced materials to address the challenges faced by existing ultrasound markers.

The key feature of Sonavex’s device lies in its unique composition. Crafted from a polymer material, the device boasts a first region that seamlessly envelops a second region, covering the entire surface area. What sets this invention apart is the incorporation of a multitude of microcavities within the second region. These microcavities are strategically dispersed to reflect ultrasonic signals transmitted at various angles, offering enhanced visibility when the device is implanted in a patient.

The microcavities play a pivotal role in altering the reflection mechanism of ultrasound waves, ensuring that acoustic signal reflections occur throughout the depth of the device. Sonavex has fine-tuned the dimensions of these microcavities, with diameters ranging from 0.1 to 950 microns, to optimize their acoustic performance. Additionally, the microcavities may contain gases like CO2 or N2, enhancing their reflective properties.

This ultrasound-detectable device addresses the issue of insonation angle dependence, a common limitation in existing markers. Sonavex’s invention provides improved echogenicity under varying angles of insonation, making it more versatile and reliable for medical professionals.

The device’s manufacturing process involves injecting a blowing agent into the polymer material, creating microcavities that reflect ultrasonic signals back to the transducer. This method ensures that the device can be visualized throughout its entire thickness rather than just the edges, a significant advancement in ultrasound technology.

Sonavex envisions various applications for this ultrasound-detectable device, from surgical implants to medical procedures requiring precise localization. The device’s echogenic properties make it an invaluable tool for visualizing internal structures within the human body, offering a level of clarity and detail previously unattainable with traditional markers.
