The effect of radiofrequency-generated thermal energy on the mechanical and histologic characteristics of the arterial wall in vivo: Implications for radiofrequency angioplasty

A New Endovascular Radiofrequency Device for Dilatation of Vascular Stenosis in a Rabbit Model

“…The combination of RF current as a source of thermal energy and balloon angioplasty has been proven to weld intimal-medial cracks of PTA both in canine in vivo studies and in human aortic specimens [8,15]. The combined delivery of pressure and thermal energy have also been proven to effectively remodel intraluminal atherosclerotic plaque and fuse intimal tears.…”

“…The RF energy is absorbed by the fluid, which is in this way heated. The tissues around the balloon are in turn heated by thermal conduction across the balloon wall [9,10,12,15,[20][21][22].…”

A new radiofrequency balloon angioplasty device for atherosclerosis treatment

“…through ablating the unwanted tissue or suppressing the proliferation of cells more sensitive to temperature [8][9][10][11][12][13][14]. Moreover, thermal treatment devices for atherosclerosis, in which radiofrequency [15][16][17][18][19][20][21], microwave [22][23][24] or laser energies [25][26][27] were utilized as input to heat the atherosclerotic artery, emerged in the 1990s. Continuous laser was used to directly dissect the plaque, which would also cause thrombosis formation and artery perforation and it is no longer utilized for angioplasty [28].…”
