The Zucker Institute for Applied Neurosciences (ZIAN), a technology accelerator embedded in the Medical University of South Carolina (MUSC), has partnered with South Carolina company Medical Access Partners LLC to commercialize “VayuClear,” a novel surgical suction de-clogging technology. With one U.S. patent already granted and the technology on track to be FDA registered and commercially available as early as mid-2022, VayuClear is poised to make a positive impact on thousands of surgeons, operating room teams and patients, in millions of surgeries every year.

In many surgeries, a narrow suction tube, with a metal or plastic tip on the end, is attached to a vacuum. This vacuum-assisted suction device is commonly used during operations to keep the surgical area free of blood, tissue and other surgical byproducts. Unfortunately, these devices tend to clog during surgery, sometimes as often as four to five times per hour. Once clogged, suctions can take upward of one to three minutes to de-clog or replace – time that can really add up, especially during a multi-hour operation. This can lead to surgical team frustration and distraction and significant time delays in the surgical procedure.

VayuClear, invented by MUSC neurosurgeon Stephen Kalhorn, M.D., is intended to address this operating room need.

Designed to de-clog surgical suctions safely in one to three seconds via pressurized saline and a patented clearing mechanism, VayuClear will minimize frustration and let the surgical team stay focused on the patient and efficiently completing surgeries.

Kalhorn described his motivation for inventing a better solution. “We commonly see clogged suction lines and suction tips during operations, leading to delays. Delays in surgery are frustrating and mean more time under anesthesia for the patient.”

That frustration led Kalhorn to partner with ZIAN to create VayuClear.

“Dr. Kalhorn had a vision of a solution that was fast and easy to use with any surgical suction, in any operating room,” said Mark Semler, ZIAN’s CEO. “This is what ZIAN was created to do – to help MUSC inventors bring patient-impacting technology to life.”

ZIAN’s team of top-notch engineers, intellectual property specialists and business development experts first helped Kalhorn to build a business plan and raise private capital to advance the project. ZIAN then worked side by side with Kalhorn to design and prototype the technology, obtain patent protection and secure a world-class industry partner – Medical Access Partners LLC – to manufacture and sell the technology, allowing surgeons around the world to benefit from this much-needed solution.

“Medical Access Partners is excited to join ZIAN and MUSC, and inventors like Dr. Kalhorn, in turning groundbreaking technologies into real-life, patient-impacting products,” said Dave Maness, Medical Access Partners co-founder and principal. “This new suction-clearing system has potential to reduce operating room time, alleviate a significant amount of frustration experienced by surgeons and operating room staff and improve patient safety in upward of 70% of surgical procedures worldwide.”

Medical Access Partners is currently in a round of investment funding, aiming to lock in manufacturing partners by the end of 2021 and, by mid-2022, to have lined up distribution partners, completed FDA registration and begun preparations for commercial launch.

For Kalhorn and operating room staff who have experienced the prototyped technology firsthand, mid-2022 can’t come soon enough. “When nurses and other surgeons see VayuClear in action, they are amazed at the simplicity and the ease,” explained Kalhorn. “One scrub nurse, when shown VayuClear, said, ‘I can't believe we haven't had this all along! This is amazing.’”
