Arterial tonometry allows non-invasive and continuous registration of the arterial pressure waveform, by applanating (flattening) a superficial artery supported by bone with an external transducer. Inspired by ocular tonometry used for eye disease diagnosis, G.L. Pressman and P.M. Newgard built the first arterial tonometer in 1963, and derived a discrete, ...

Vessel loops are invaluable in vascular surgery. Unfortunately, they frequently slide toward the ends of the arteriotomy, making precise stitch placement difficult. By bringing the vessel loops out separate stab wounds, we improve visualization at the heel and toe of the anastomosis while preserving arterial elevation and hemostasis.
