Abstract:
In order to solve the heat transfer mechanism in radiofrequency treatment of atherosclerosis, we design two experimental structures to simulate the plaque, and use three frequencies and a variety of electrode arrangement, to study the heat transfer mechanism and heating capacity under the special structure. The results show that the temperature increment and heating area increase with increasing frequency. Under the structure in which the lipid particles are embedded in the fiber cap, using three electrodes with opposite polar arrangement between middle electrode and others, achieves effective heating to lipid pool in the plaque.
