Summary of Clinical Data

During a clinical study for a different use of the Spiration Valve, 4 patients were treated for air leaks. This is called “compassionate use” and is allowed by the Food and Drug Administration (FDA) when no other treatment is available.

Sixteen valves were placed in the 4 patients; so the average number of valves per patient was 4. All 4 patients had an immediate decrease or end to their air leak. No problems related to the device were reported. See Table 1 below for a summary of the problems related to the procedure.
