Cannula for Minimally Invasive Cardiac Surgery
(CHMC Ref. Id: 2005-0703)
Overview:
The standard right angle cannula used during cardiac surgery requires the technical expertise and skill of multiple individuals and is associated with significantly greater blood loss. Further, it has limited application during surgical approaches conducted via minimally sized incisions or alternative incisions (e.g., thoracotomy). While groin cannulation has facilitated and overcome some of these limitations, the standard groin cannulas can also be limited in certain circumstances (e.g., patients with peripheral vascular disease - not uncommon among cardiac patients) and also require an additional incision (in the groin) in a patient that could otherwise be left without. Finally, these cannulas often do not have the same hemodynamic and flow advantages as standard angled cannulas, leading to the necessity of additional technologies such as vacuum assist and their associated costs and disadvantages. This right-angle cannula is designed to overcome these limitations.
