Retrograde cannulae are designed to deliver cardioplegia solution to the heart via the coronary sinus in the reverse direction of normal blood flow (retrograde perfusion). These cannulae are offered in either auto inflating or manual inflating cuff models. The purpose of the cuff is to occlude the opening of the coronary sinus, forcing cardioplegia flow to the coronary vessel bed of the heart. Manual inflate models require the clinician to inflate the cuff using an included syringe before delivering cardioplegia. Auto inflate models are inflated by the flow of cardioplegia through the cannulae body and cuff. Medtronic Retrograde Cannulae are offered in many different configurations of cuff, tip, stylet and handle design as well as choices of silicone or PVC body construction. Our product breadth ensures the availability of a cannula to meet your specific needs.
The MiRCSP is a retrograde cardioplegia cannula for cardiac surgeons who seek to differentiate themselves through use of less invasive valve procedures performed through small thoracic incisions. Unlike traditional retrograde coronary sinus perfusion cannulae, the new MiRCSP includes the unique features of tip deflection and sweep that allow the surgeon to place it trans-atrial into the coronary sinus through small thoracic incisions (mini-sternotomy or right thoracotomy). Additional features enhance the visibility on echocardiography or fluoroscopy to further facilitate cannula placement.
