Antegrade cannulae are designed to deliver cardioplegia solution to the heart via the coronary ostia in the normal direction of blood flow (antegrade perfusion). Medtronic offers both aortic root cannulae and coronary ostial cannulae. Aortic root cannulae are intended to infuse cardioplegia directly into the aortic root near the aortic valve while coronary ostial cannulae are held on or placed in the coronary ostia.
We offer aortic root cannulae in a standard 5.25 inch length, a 12.5 inch length and a 2.5 inch length to accommodate various techniques. Allowing for further customization, we offer aortic root cannulae with various tip lengths, with or without a vent line and the option of Flow-Guard™, our hemostasis management introducer. Medtronic also offers a dual lumen aortic root cannulae with a patented tip, which allows simultaneous infusion of cardioplegia and aspiration of air from the aorta. Our product breadth ensures the availability of a cannula to meet your specific needs.
The most recent addition to our antegrade line, the MiAR cannulae is 12.5” long, providing the extra length needed to ensure the luer connection rests outside of the chest incision. The MiAR features the Medtronic Flow-Guard System, which maintains hemostasis and allows retraction of the needlepoint into a rigid fitting after placement of the cannulae.
This unique cannula allows for the simultaneous delivery of cardioplegia and aspiration of the aorta and left heart. These cannulae feature dual lumen tips attached to clear bodies with a segregated vent line. All cannulae are supplied with a stainless steel introducer needle.
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.
Designed to deliver cardioplegia solution to the heart through the coronary sinus, these cannulae feature a kink-resistant, wire-wound silicone body and smooth manual inflate cuff. These manual inflate RCSP models include a pressure monitoring line with or without an integral stopcock and a guidewire stylet with a male luer handle or Tru-Touch® handle. A syringe is included for cuff inflation.
Cardioplegia adapters are designed to permit customization of the cardioplegia circuit. Adapters can be used to connect multiple cardioplegia cannulae and/or vein graft cannulae to a single inlet source, switch between antegrade and retrograde delivery of cardioplegia and provide the option for attaching a vent line to the cardioplegia cannulae.
Additional adapters are available to extend the length of the cardioplegia circuit, recirculate the cardioplegia solution or provide an extension to the pressure monitoring line.
Care and caution should be taken to avoid damage to vessels and cardiac tissue during cannulation or other cardiac procedures.
