Why was the SCOOP-2 catheter discontinued?
A. For the past 15 years Transtracheal Systems has provided two different catheters for transtracheal oxygen administration. They have been identified as SCOOP-1 (LF for low flow) catheter, and SCOOP-2 (HF for high flow) catheter. They are identical in length and diameter, but the SCOOP-2 differs from the SCOOP-1 in that the SCOOP-2 has 6 extra hoses or side ports drilled near the tip of the catheter. Conceptually, the SCOOP-2 catheter was designed with the extra ports as it was originally thought that the ports would provide greater comfort and perhaps better efficiency at higher flow rates. It is our belief that there is no significant advantage to using the SCOOP-2 catheter over the SCOOP-1 catheter and therefore have elected to phase out the SCOOP-2 catheter. The SCOOP-1 catheter is FDA approved for liter flows up to 12 liters per minute, and provides greater flexibility than the SCOOP-2. The SCOOP-1 catheter can be cleaned in place and/or removed for cleaning. This allows for more
