Recovery in Millimeters, Not Months

Micro-invasive Carpal Tunnel Release with the
SX-One MicroKnife™

Carpal tunnel syndrome affects more than 12 million Americans and results in 500,000 surgeries every year. Traditional open and endoscopic carpal tunnel release (CTR) procedures can be effective but may result in a lengthy recovery period and a large and sometimes painful scar.

The new, ultra-low profile SX-One MicroKnife™ is an innovative surgical device that enables Micro-invasive Carpal Tunnel Release through a single micro-incision (4-5 mm) under ultrasound guidance, or with a traditional mini-open incision without ultrasound guidance. Minimally invasive techniques can result in a faster recovery time and minimal scarring.1-3

Micro-incision, Micro-recovery

The SX-One MicroKnife™ works through an incision that’s up to 5 times smaller than the incision made during traditional CTR surgery4—an incision so small, it can be closed with a small adhesive bandage or strip. Utilizing proprietary Meerkat Technology™, the device enhances the protection of nerves, blood vessels, tendons, and other sensitive and variable anatomic structures during the procedure, adding a new level of safety to carpal tunnel release surgery. This combination results in a low-trauma surgical environment that has been associated with faster pain relief and recovery for CTR patients.1-3 Immobilization is unnecessary so patients can begin rehabilitation and get back to their jobs and their lives.1,2

Protects Patient Anatomy and Promotes Rapid Recovery

Micro-invasive CTR benefits patients, almost immediately:

  • Better patient outcomes with ultrasound-guided CTR compared to traditional surgery1,2
    • 5 times faster pain relief
    • Promotes rapid patient recovery
    • 5 times faster return to normal daily activities
    • Significantly less pain medication utilized
  • Consistent safe zone enhances the protection of sensitive anatomic structures during ligament transection1,2

The SX-One MicroKnife™ Surgical Device

The SX-One MicroKnife™ was developed by musculoskeletal physicians and leading ultrasound imaging experts at the Mayo Clinic. The patent pending surgical device is designed for physicians who perform carpal tunnel release 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 may be performed in a surgery center or office setting.

The Micro-invasive CTR Procedure:*

  1. The transverse carpal ligament and relevant anatomic structures are visualized directly via ultrasound imaging
  2. The SX-One MicroKnife™ is inserted into the wrist through a 4-5 mm micro-incision
  3. Meerkat Technology™ coordinates the deployment of Stealth MicroGuards™ to expand and maintain the safe zone between the TCL Blade™ and the nearby nerves, blood vessels, tendons, and other sensitive anatomic structures for enhanced protection during ligament transection1,2
    • When inflated, the Stealth MicroGuards™ move laterally from the shaft to expand and maintain the safe zone
  4. The TCL Blade™ is advanced from the tip of the device to transect the transverse carpal ligament
    • The TCL Blade™ is positioned entirely within the tip and shaft of the SX-One MicroKnife™ to enhance the protection of nearby anatomic structures and can only be activated after the Stealth MicroGuards™ are deployed
  5. The TCL Blade™ is returned to the inactive position and the Stealth MicroGuards™ are deflated; the tip of the instrument is then used to probe the ligament to ensure complete transection
  6. The SX-One MicroKnife™ is removed, and the micro-incision can be closed with an adhesive bandage or strip; sutures or stitches are optional
