These surgical instruments also use the heat generated from the friction of the blade vibrating against the blood vessel to coagulate and seal those blood vessels in order to prevent bleeding.
The patents in suit are directed to surgical instruments that use ultrasonic energy created by blades vibrating at high frequencies to cut tissue and blood vessels.
Claim 17 of the '501 patent recites that the claimed ultrasonic surgical shears include a tissue pad and blade that define a clamping surface area.
The specification explains that this "clamping surface area is the area where the blade and the tissue pad are in close proximity because the clamping arm is in a closed position." In the primary disclosed embodiment, the clamping surface area is about 0.033 square inches.
There were two puff pieces about it this morning [1, 2], the latter of which says: “A new patent for “whole brain” systems for autonomous robotic control has been issued by the U. Patent Office to Neurala, the software company that invented The Neurala Brain, a deep learning neural networks platform.
This new invention will enable AI to function more like a human brain because it integrates multiple brain areas.” I have personally developed programs in this area (machine learning, autonomous vehicles etc.) and it’s abundantly clear that it’s all about software.
