    Area of Science:

    • Cardiovascular Surgery
    • Medical Device Technology
    • Cardiac Anesthesia

    Background:

    • Coronary artery perfusion is critical during cardiac surgery.
    • Existing methods for delivering cardioplegia can cause ostial trauma.
    • Minimizing iatrogenic injury is paramount for patient outcomes.

    Purpose of the Study:

    • To introduce a new coronary perfusion cannula design.
    • To evaluate the cannula's ability to deliver solutions without causing trauma.
    • To assess the safety and efficacy of the device in cardiac procedures.

    Main Methods:

    • Development of a specialized coronary perfusion cannula.
    • In vitro and/or ex vivo testing of the cannula's delivery capabilities.
    • Assessment of cannula impact on coronary ostia and proximal artery.
