TunnelVision Endoscopic Soft Tissue Release System and the HBL Blade Assembly

The TunnelVision Endoscopic Soft Tissue Release System is a minimally invasive surgical system for ligament and fascia release procedures, including carpal tunnel release in the wrist and cubital tunnel release in the elbow. It consists of a reusable endoscope, handpiece, manual surgical instruments, and sterilization tray, plus a single-use HBL Blade Assembly that performs the tissue cutting.

The subject device employs the same technological elements as the predicate: endoscopic visualization, a handpiece to control the cutting instrument, a blade assembly that cuts in retrograde motion, a sterilization tray for reusable components, and manual surgical instruments. The document states there are no technological differences between the subject and predicate devices—materials, manufacturing processes, and technological characteristics are identical.

Not stated in this summary. The document lists performance testing categories (blade retention force, endoscope deflection, sterilization validation, biocompatibility, life cycle testing, packaging/transport testing, and human factors cadaveric evaluation) but does not cite specific ISO, IEC, or ASTM standards.

The TunnelVision system has the same intended use and technological characteristics as the predicate devices (MicroAire SmartRelease K181819 and HBL Blade Assembly K222490), with no differences in design, materials, or performance that raise new questions of safety or effectiveness. Performance validation and usability testing confirm substantial equivalence.
