Benefits of technology

This patented technology allows for precise measurement of blood flow velocity without causing damage or discomfort during surgery procedures. By placing an implant inside this system, it becomes more effective at regulating fluid flows within body organs such as liver arteries.

Problems solved by technology

This patents describes various ways to treat liver cancer such as partial removal of the gallblasts from its rootlets before treatment. One approach involves stopping certain parts of the gut lining upstream to block off any remaining ones while leaving other areas unblockable. Another option involve performing an open procedure where only some small holes remain inside the body's circulation systems. These approaches aim at reducing patient-related issues like abdominal pain, bowel rupture, cardiovasculatory problem, etc., resulting in improved outcomes compared to traditional procedures.
