Machine Keeps Heart Beating Outside of Body

Who needs a body these days anyway?

 

Researchers at the North Carolina State University has developed a machine that can keep a heart beating outside the body. The potential medical benefit is huge, though for whatever reason I kept on thinking about Dr. Frankenstein:

“Researchers can obtain pig hearts from a pork processing facility and use the system to test their prototypes or practice new surgical procedures,” says Andrew Richards, a Ph. D. student in mechanical engineering at NC State who designed the heart machine.

The computer-controlled machine, which operates using pressurized saline solution, also allows researchers to film the interior workings of the pumping heart – enabling them to ascertain exactly which surgical technologies and techniques perform best for repairing heart valves.

Robotic System That Will Operate On A Beating Heart

Robotic System That Will Operate On A Beating Heart 

This device lets surgeons attach small anchors to tissue inside a beating heart by compensating for the heart’s movement. 

Fixing the heart is hard. Certain procedures have to be performed on a stationary organ, so the heart is stopped and the patient put on a cardiopulmonary bypass machine. But stopping the heart increases the risk of brain damage. Now researchers at Harvard University and Children’s Hospital Boston are testing a robotic system that could help surgeons perform a common valve repair while the heart beats on. The system uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a patient’s mitral valve as it moves.

The Grand Pug of Determination

 This Pug has determination written all over her face

This 10 month old pug puppy is going to get every last treat if it kills her.  She finally figured out how to get them all in the end, even though she takes a bit of a beating from the cat. While the cat has no claws and she was never in any real harm, you can hear the bops from the cat. The second half shows her really reaching and stretching for the treats.

Second animal video after the jump.
