ROCHESTER, Minn.–(BUSINESS WIRE)–Sonex Health has announced the successful completion of the first
ultrasound-guided carpal tunnel release procedure in the United States
using the SX-One MicroKnife™. The SX-One MicroKnife™
is an ultra-low profile surgical device that allows physicians to
perform carpal tunnel release surgery through a single micro-incision
(4-5 mm) using ultrasound guidance. In addition, the device is designed
to protect sensitive anatomy when the transverse carpal ligament (TCL)
is cut during the procedure.
Performed by Harvard and Mayo Clinic-trained plastic surgeon Craig
Johnson, MD, at the Aurora Health Care Clinic in Sheboygan, WI, the
Micro-invasive Carpal Tunnel Release (CTR) procedure is a new treatment
option for patients who suffer from carpal tunnel syndrome. “In my
experience, the SX-One MicroKnife™ addresses unmet needs in
minimally invasive carpal tunnel release surgery,” said Dr. Johnson.
“We’re always looking for new ways to help our patients and the SX-One
MicroKnife™ offers an innovative way to treat carpal tunnel
syndrome by promoting rapid recovery so patients can get back to their
jobs and lives faster.”
The SX-One MicroKnife™ enables Micro-invasive CTR through a
micro-incision that’s up to five times smaller than the incision made
during traditional CTR surgery1—an incision so small, it can
be closed with a small adhesive bandage or strip. The SX-One MicroKnife™
features Meerkat Technology™ that performs two critical
functions: it stores key safety and cutting elements inside the device
to enable entry and exit through a micro-incision and once inside the
wrist, the safety and cutting components are deployed to enhance the
protection of nerves, blood vessels, tendons, and other sensitive
anatomy during the procedure. The combination results in a low-trauma
surgical environment that has been associated with faster pain relief
and recovery in patients.2,3
“Our first-in-man surgery represents Sonex Health’s commitment to
providing physicians with a minimally invasive solution for performing
CTR,” said Dr. Darryl Barnes, CEO of Sonex Health and co-inventor of the
SX-One MicroKnife™. “We look forward to helping physicians
offer their carpal tunnel syndrome patients an option that helps people
get out of pain and back to work and normal activities quickly.”
About The SX-One MicroKnife™
The ultra-low profile SX-One MicroKnife™ was developed by
physicians and leading ultrasound imaging experts at the Mayo Clinic.
The patent pending surgical device is designed for physicians who
perform CTR surgery under ultrasound guidance or with a traditional
mini-open incision technique. Micro-invasive CTR with the SX-One
MicroKnife™ is an outpatient procedure that can be performed
in an office setting or a surgery center.
Studies referencing Micro-invasive Carpal Tunnel Release, have shown:
Better patient outcomes with ultrasound-guided CTR compared to
- 5 times faster pain relief
Promotes rapid patient recovery
- 5 times faster return to normal daily activities
- Significantly less pain medication utilized
The consistent safe zone made possible by Meerkat Technology™
enhances the protection of sensitive anatomy during ligament cutting2,3
