SX-One MicroKnife is rebranded as UltraGuideCTR. UltraGuideCTR is intended to transect the transverse carpal ligament for the treatment of carpal tunnel syndrome.UltraGuideCTR is a disposable device intended to create space within the carpal tunnel and transect the transverse carpal ligament (TCL) for the treatment of carpal tunnel syndrome.
A sterile, hand-held, manual, surgical instrument designed for percutaneous or mini-open transection of the transverse carpal ligament for median nerve decompression. It typically consists of a tubular fenestrated probe that contains a wire with a toothed cutting segment, attached to a handle with a lever to extend and retract the wire. The probe is inserted through the carpal tunnel and the wire extended to expose the cutting section through the probe window, and distally through the skin so that it can be gripped to enable a manual sawing motion to transect the ligament. The probe may include a conductor for connecting to an external nerve-locating system. This is a single-use device.
