Benefits of technology

This patented describes two technical features: Firstly, it suggests that an improved method called Helmholtz Ultrasound (HUS), which uses special tools or techniques in medical procedures such as angiography, has been developed over recent years due to its ability to provide detailed images from inside blood vessels without causing damage during surgery. Secondly, there are also proposals suggesting how small motors like spiraling type ones could replace traditional methods used at large distances within body tissues. These improvements make them more effective but still have their own limitations compared to current technologies.

Problems solved by technology

This patented technical solution describes an improved design that allows for precise control over blood vessel lumen dimensions during minimizing invasive procedures while also being able to operate within small spaces without causing any issues like electrical noise.
