The Tenax® Laser Resistant Endotracheal Tube is intended for endotracheal intubation. It is indicated for use for all types of surgical procedures involving carbon dioxide (10.60 microns), KTP (532 nm) or Blue Laser (445mm) laser use (normal pulsed or continuous beam delivery in the non-contact mode), when endotracheal intubation is required to administer anesthetic gases or to overcome emergency obstruction of an airway.
The Tenax® Laser Resistant Endotracheal Tube is an endotracheal tube with two inflatable cuffs. It is indicated for use in surgical procedures where intubation is required in the presence of KTP, 445nm Blue Laser, or CO2 lasers. The device is provided sterile (EO). After use, the device is discarded and disposed of in accordance with local regulations. There are no associated device accessories.

The aeris Balloon Dilation Catheter is intended for use in adult and pediations to dilate strictures of the airway.
The aeris Balloon Dilation Catheter is comprised of a sinqle lumen catheter with a high pressure balloon near the distal tip. A stylet is provided to facilitate advancement of the balloon dilation catheter to the desired location. The stylet must be removed before inflation of the high pressure balloon. A luer lock at the proximal end is used for placement of the stylet and injecting sterile water into the balloon. Two radiopaque markers, located on the catheter, inside the balloon, can be used to confirm balloon placement under Fluoroscopy.
The aeris Balloon Dilation Catheter includes inflation balloons of diameters 5, 7, 8, 9, 10, 12, 14, and 16 mm with complementing characteristics as shown in Table 1.
The provided text describes the acceptance criteria and the results of various bench tests for the aeris Balloon Dilation Catheter as part of a 510(k) submission for substantial equivalence. It does not include information about a study involving human readers, AI, or specific details on studies for ground truth establishment for a test set. This is a technical device submission, not an AI/algorithm-based diagnostic device.
Here's the breakdown of the available information:
