Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Hot-wire anemometers have a very short time-response, which makes them ideal to measure rapidly fluctuating phenomena such as turbulent flows. The purpose of this experiment is to demonstrate the use of hot-wire anemometry.

Animal models of atherosclerosis are essential to understand the mechanism and to investigate newer approaches to prevent plaque development or rupture, a leading cause of death in the industrialized world. This protocol uses a combination of balloon injury and cholesterol rich diet to induce atherosclerotic plaques in rabbit iliac artery.
FAQs
The guidewire provides a track that the balloon catheter follows through tortuous vascular anatomy. This arrangement helps the operator steer the device toward the target lesion and position the balloon across the stenosis before treatment. Maintaining guidewire access also supports controlled device movement during positioning, inflation, deflation, and removal.
Controlled inflation allows the balloon to apply radial force against the narrowed vessel in a deliberate manner. As the balloon expands, that force widens the stenotic region and can improve the channel available for blood flow. Pressure control therefore connects the mechanical action of inflation with accurate treatment of the obstruction.
Deflation reduces the balloon’s expanded profile so the catheter can be withdrawn from the treated area. The guidewire remains in place during this step, preserving access to the vessel after balloon removal. This separation of catheter withdrawal from guidewire position supports continued control of the treatment pathway during the intervention.
The operator first advances the guidewire through the vessel toward the stenosis, then tracks the balloon catheter over the wire until the balloon is positioned across the narrowed segment. Inflation under controlled pressure expands the vessel, after which the balloon is deflated and removed while the guidewire maintains access.
They are used when vascular narrowing obstructs blood flow in coronary or peripheral vessels. In either setting, the device supports minimally invasive dilation by reaching the stenosis through a small access site. Treatment is aimed at widening the obstructed segment and restoring perfusion to the downstream vascular territory.
Accurate placement ensures that inflation acts across the intended stenosis rather than at an unintended location. The guidewire helps the operator navigate tortuous anatomy and align the balloon with the obstruction. Correct positioning is especially important because the desired outcome is localized vessel dilation that improves blood flow while preserving a minimally invasive approach.
