Kona Surround Sound® Technology

At Kona Medical we have developed an ultrasound-based platform which enables non-invasive imaging, targeting, tracking, and treatment of soft tissue structures throughout the body without radiation and without the cost or complexity of MR and other technologies. Our Surround Sound® system utilizes ultrasound imaging to guide the external delivery of focused ultrasound energy to specific target tissue, while automatically tracking movement and enabling continuous therapy delivery.

Our initial clinical application addresses high blood pressure (hypertension) through ablation of the renal nerves. Renal nerves are located proximal to the renal arteries, which provide blood flow to the kidneys. Renal nerves are part of the sympathetic nervous system and play a significant role in determining blood pressure. Clinical data have shown that ablation of renal nerves can result in profound and lasting reduction in hypertension in patients whose blood pressure is not adequately controlled by medication.

In contrast to catheter-based renal denervation systems, which rely on internal delivery of energy through the wall of the renal artery to ablate renal nerves, our system delivers the energy from outside the body to create an ablative field around the vessel which ablates the nerves without impacting the artery. Kona’s fully-integrated, portable, standalone system can be used in virtually any exam room in a hospital, office or clinic, and does not require a catheterization lab.

Ultrasound-based, non-invasive RDN has the potential to greatly reduce cost, lower risk, and improve access to millions of hypertension patients worldwide who are not adequately controlled by drug therapy.

Kona has a foundational intellectual property position in therapeutic ultrasound, with numerous US and International patent applications covering its platform technology.
