PURPOSE Vessel damage after clamping may affect the success of surgical operations. A new pressure controlled clamp (SMA clamp) was designed using super elastic property of shape memory alloy (SMA) to realize atraumatic vessel occlusion. The ability and biological effect of the SMA clamp to control pressure was investigated in vivo. METHODS The loading-displacement curves of the SMA clamps (e...

The central aorta acts as a compliant tube that buffers and conducts pulsatile ventricular output (7) and contributes mostly to total compliance of the arterial tree. The mathematical model introduced by O. Frank (7) describing pulse wave propagation and arterial mechanical properties assumes that the arterial tree is an elastic chamber (windkessel) in which the diastolic pressure decays expone...

Microvessels -blood vessels with diameter less than 200 μmform large, intricate networks organized into arterioles, capillaries and venules. In these networks, the distribution of flow and pressure drop is a highly interlaced function of single vessel resistances and mutual vessel interactions. Since, it is often impossible to quantify all these aspects when collecting experimental measures, in...

coronary heart disease has been one of the main threats of human health. coronary angiography is taken as the “gold standard” for the assessment of coronary artery disease. but sometimes, the images are difficult to interpret visually because of the crossing and overlapping of the vessels in the angiograms. vessel extraction from x-ray angiograms has been a challenging problem for several years...

The bronchial venous system closely communicates with the pulmonary circulation. To assess the changes in the bronchial circulation in chronic pulmonary venous hypertension, fiberoptic bronchoscopy and right heart catheterization were performed in 31 patients with mitral stenosis. Nonpulsatile submucosal vessel dilatation, consistently seen in all patients and called the vessel dilatation score...

AIMS To determine central retinal vessel collapse pressure in chronic open angle glaucoma. METHODS For 19 eyes with chronic open angle glaucoma and 27 eyes of a control group, central retinal vessel collapse pressure was measured by a Goldmann contact lens fitted with a pressure sensor in its holding grip. RESULTS Central retinal vein collapse pressure was significantly (p=0.001) higher in ...
