Positive trial results show ultrasound energy can treat high blood pressure


A procedure called renal denervation resulted in medication-free blood pressure control in over a third of trial patients

A promising new study is documenting the long-term effects of a novel surgical procedure using ultrasound to reduce blood pressure in patients with hypertension. It’s hoped the one-off procedure, called renal denervation, could offer patients an alternative option to taking hypertension drugs.

Renal denervation has been in development for almost a decade, however inconsistent clinical trial results have slowed the progress of this novel surgical procedure. The treatment involves delivering ultrasound pulses to nerves in the walls of renal arteries. This procedure has been found to reduce blood pressure, particularly in cases where hypertension has not effectively responded to traditional medications.

Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation—no bigger than a Band-Aid—is portable, wearable and can be powered by a smartphone.

New technology promises the ability to regrow teeth


New low-intensity pulsed ultrasound device helps regrow teeth.

Researchers at the University of Alberta in Canada have developed a low-intensity pulsed ultrasound (LIPUS) technology that they hope will ultimately be able to re-grow lost or severely damaged teeth from the root, eliminating the need for pricey prosthetics and painful procedures.
