| Content Provider | The Lens |
|---|---|
| Abstract | Disclosed are methods, apparatus, and systems useful for detecting leaks in pleural tissue. Also disclosed are methods of detecting and sealing such leaks. Indicator dye or stain is aerosolized and delivered to the lung via anesthetic equipment, oxygen tube, endoscope, or other suitable equipment, the dye is allowed to travel through the lung along the path or paths of least resistance emerging at the surface of the lung, staining the tissue indicative of a leak. Some embodiments include introducing one part of a two part sealant with the dye, and applying the second part of the sealant to the stain identified leak locations. |

| Claim | A method of identifying and sealing an air leak in lung tissue in a patient in need thereof, the method comprising: introducing a first composition comprising an indicator and a first component of a multipart sealant into the lung via an aerosol or nebulizer, allowing the first composition to accumulate at one or more air leak, applying a second composition comprising a second component of a multi-part sealant externally to the lung at locations where the indicator has accumulated, and allowing the first component and the second component of the multi-part sealant to cure with one another to form a pleural sealant. The method of claim 1 , wherein the first composition is introduced to the patient in need thereof via a breathing apparatus. A method of identifying and sealing an air leak in lung tissue in a patient in need thereof, the method comprising: introducing an indicator compound into the lung via an aerosol or nebulizer, allowing the indicator compound to accumulate at one or more air leak, applying externally to the lung a suture or sealant at a location identified by accumulated indicator compound. The method of claim 1 , wherein the indicator is methylene blue. The method of claim 3 , wherein the external application of the sealant also includes an application of an indicator. |
