Early experience with a new aortic clamping system designed for port access cardiac surgery: the PortaClamp.

We report a clinical study to demonstrate the feasibility and safety of a new aortic crossclamping concept for use in port-access cardiac surgery. The limited access to the aorta in minimally invasive cardiac surgery mandates specific clamping modalities, which entail specific limitations, drawbacks, and costs. Therefore a new autoguided, extravascular, and atraumatic clamping system (PortaClamp) was developed to facilitate port-access surgery while potentially avoiding the complications and costs inherent to endoluminal clamping or "blind" crossclamping.Clinical TrialJournal Article
