Clinical Need

  • Lung cancer is leading cause of cancer death worldwide & lung biopsy is the gold standard method of diagnosis.

  • Early diagnosis has been proven to save lives making lung biopsy a vital armament in the battle against lung cancer.

  • Approximately, 1 in 3 patients undergoing a lung biopsy suffer from a collapsed lung, known as pneumothorax.

  • This dangerous complication converts a routine outpatient procedure to one requiring hospitilisation, for up to a week, for invasive treatment & follow-up.

  • This results in healthcare costs in excess of $15,000 per patient making it the No. 1 hospital cost & complication post lung biopsy.


  • Selio Medical adopts an unique approach by providing pneumothorax protection before the biopsy even takes place.

  • The Selio Sealant System is a single use, prophylactic device, comprising a percutaneous delivery needle together with a novel biodegradable hydrogel sealant.

  • Our proven patented technology seamlessly integrates with the current standard of care and enables the clinician to pre-seal the access route into the lung before the biopsy.

  • The Selio Sealant System provides pneumothorax protection for the in-patient, thereby allowing the patient to safely return home on the same day as their procedure. This significantly improves the patient’s quality of care while preventing further treatment and costs.

  • Co-Founders Colm McGarvey & Dr. Garrett Ryan identified this large unmet clinical need during the BioInnovate Fellowship Programme at the National University of Galway (NUIG) & at the University College Cork (UCC). The project then spun-into Trinity College Dublin where it was de-risked with support from Enterprise Ireland.

    Selio Medical spun-out of Trinity College Dublin into a new facility located in the heart of Dublin, significantly expanding the team with the support from our international corporate investor, EIT Health and the European Innovation Council (EIC).

    Selio Medical continues to develop our platform technology to improve the lives of lung cancer patients worldwide.
