Roger Sur

Title: Roger Sur and His Ultrasound Visualization Invention.

Introduction

Roger Sur is an inventor based in San Diego, California. His patent work addresses ultrasound-guided needle placement, with a focus on making a needle’s position easier to visualize during insertion into tissue.

Latest Patents

Sur is associated with 1 patent, titled “Ultrasound Visualization Device.” The invention describes an assembly in which a needle is inserted into a sheath, creating a channel between the needle’s outer surface and the sheath’s inner surface. Fluid travels through this channel, where features in the assembly encourage the formation of ultrasonically visible features. These features emerge from the end of the sheath and can be detected through ultrasonic imaging, helping clinicians visualize needle positioning.

Career Highlights

Sur is associated with the University of California. His patented device reflects an application of engineering to a practical challenge in ultrasound-guided procedures: improving the visibility of a needle’s position within tissue.

Collaborations

Sur’s listed coworker is Paul Zupkas. Their association provides context for the professional environment connected with Sur’s invention.

Conclusion

Roger Sur’s “Ultrasound Visualization Device” uses fluid and ultrasound-detectable features to support visualization of needle placement, illustrating his contribution to medical imaging technology.
