| Prana Thoracic | Houston-based medical device startup Prana Thoracic, Inc. is dedicated to developing solutions for early intervention in lung cancer. We are an experienced team of surgeons, engineers and entrepreneurs on a mission to tackle lung cancer; the #1 cancer killer in the US.The paradigm of screening, detection, and early intervention that has beendeployed in other major cancers has so far eluded lung cancer. As a result, only 16% of lung cancers are found at an early stage and the current 5-year survival rate is < 20%. Recent changes to lung cancer screening guidelines have illuminated a path to improving outcomes in lung cancer. However, these advances rely on excising suspicious nodules and providing sufficient tissue for definitive diagnosis. We believe this is the missing piece of the puzzle, and physicians need a new generation of surgical oncology tools for lung cancer.Prana Thoracic plans to revolutionize the early diagnosis and treatment of lung cancer by making it easier and less invasive to deal with the rapidly growing number of early suspicious lung nodules; ensuring that we do not miss the window of opportunity to intervene early. | $3M | Series A | Jun 18, 2024 |  |
