Sonex Health reduces invasiveness, improves safety, and lowers the cost of care through transformative ultrasound. “Refined simplicity” is the guiding principle behind Sonex Health. To drive efforts and innovations that result in elegant, effective solutions to some of the healthcare system’s most pressing needs. Mayo Clinic physicians Darryl Barnes, MD and Jay Smith, MD, and business operations expert Aaron Keenan founded Sonex Health in 2014. Sonex Health has developed the SX-One MicroKnife(R) with Meerkat Technology™ to treat carpal tunnel syndrome in a novel fashion, termed Micro-invasive Carpal Tunnel Release. This innovation allows a procedure that once took place in an operating room to be safely and effectively performed in a surgery center or office setting, resulting in rapid patient recovery, improved cosmesis, and reduced costs. The ultra-low-profile SX-One MicroKnife with Meerkat Technology is an innovative surgical device that enables physicians to perform Micro-invasive Carpal Tunnel Release surgery through a single micro-incision under ultrasound guidance, or with a traditional mini-open incision without ultrasound guidance.  The SX-One MicroKnife utilizes a micro-incision that’s up to five times smaller than the incision made during traditional CTR surgery—an incision so small, it can be closed with a small adhesive bandage or strip instead of sutures or stitches.  The result is a low-trauma surgical environment that has been associated with a more rapid recovery. Immobilization is unnecessary so patients can begin rehabilitation and get back to their jobs and lives.

Sonex Health develops ultrasound-guided devices for treating common orthopedic conditions affecting the extremities. Its flagship product, UltraGuideCTR, received FDA clearance in 2019 and is designed to treat carpal tunnel syndrome. It is a single-use, hand-held device that enables physicians to perform carpal tunnel release (CTR) procedures through a small wrist incision using real-time ultrasound guidance.

Convergent Dental, Inc. is a privately owned dental equipment and technology company. Its flagship product, Solea, is the only CO2 laser cleared by the FDA for all-tissue indications, delivering an anesthesia-free, blood-free, and suture-free experience for dentists and patients. Solea represents a breakthrough in dental laser technology, offering a distinct experience compared to traditional instruments or earlier laser treatments.
Solea is a novel 9.3-micron CO2 laser that nears the peak absorption of hydroxyapatite (enamel), enabling it to vaporize enamel with speed and precision. This unique wavelength, coupled with computer-controlled motors (galvos) that manipulate the beam thousands of times per second, allows dentists to perform procedures ranging from hard tissue to soft tissue with total control and efficiency.
A key feature of Solea is its variable-speed foot pedal, which lets dentists seamlessly transition from hard to soft tissue by adjusting the pressure applied. This intuitive design streamlines the learning curve for dentists accustomed to using a drill. Solea's three ergonomic handpieces – Contra-Angle, Straight, and Ultraguide – further enhance its versatility across various procedures.
Solea not only improves patient experiences but also offers practice benefits such as increased productivity, new patient flow, and efficiency gains. In October 2022, Convergent Dental received FDA clearance for Solea to aid in reducing mineral loss in dental enamel, protecting teeth against acid attack and caries development. This breakthrough application was commercially launched in November 2023 under the name Solea Protect.
