Minor Thoughts from me to you

This is cool. It's amazing how far and fast medical technology is developing. I can't wait to see what will be available by the time I need serious medical help.

In 2001, the FDA approved the use of capsule endoscopy, which uses a capsule size camera [1.2 inches long by 0.4 inches in diameter]. These are passive systems. There is work to make smaller robotic systems and systems that can perform more of the capabilities of regular endoscopes. These capabilities include therapeutic and diagnostic operations such as ultrasound, electrocautery, biopsy, laser, and heat with a retractable arm.

Scientists at the Technion University, teamed with a researcher from the College of Judea and Samaria, have developed a miniature robot that can move within the bloodstream.

The miniature robot has been planned and constructed (2007), that has the unique ability to crawl within the human body's veins and arteries," said Dr. Nir Shvalb of the College of Judea and Samaria. The Israeli robot's diameter is one millimeter.

The researchers stress that the project is an "interesting development, but it has a long way to go before it is used in medicine." Solomon says that the tiny robot could be controlled for an unlimited amount of time to carry out any necessary medical procedure. The power source is an external magnetic field created near the patient that does not cause any harm to humans but supplies an endless supply of power for it to function. The robot's special structure enables it to move while being controlled by the operator using the magnetic field.
