Sentence examples for radiofrequency electrical from inspiring English sources

When the tip of the catheter is up against the offending tissue, which is usually in or near the pulmonary veins, a radiofrequency electrical current is passed through the catheter to destroy, or ablate, the target.

Destruction is achieved through various methods, the most commonly used 8 being high temperature fluids within a balloon (Thermachoice and Cavaterm) 9 10 11 or application of microwave (Microsulis) 12 13 or bipolar radiofrequency electrical energy (Novasure).

Application of porous silicon for electrical isolation in radiofrequency devices is widely studied [1, 2].

The transfer of magnetic radiofrequency energy to heat and electrical energy depends on the pulse sequence parameters, the whole-body averaged and specific absorption rates (SAR), spatial relation and orientation with regards to the coil and configuration of the lead (composition, length and orientation) [6].

Treatment options include surgery to remove a section of the liver, and radiofrequency ablation, which is a small electrical current used to destroy cancerous cells.

Designed to be used as an adjunct to current surgical methods, the device measures the local electrical properties (in the radiofrequency range) of breast tissue.

Hendon is currently working with Vivek Iyer, a cardiac electrophysiologist at Columbia University Medical Center, to explore the use of OCT and spectroscopy in the treatment of heart arrhythmias, where surgeons often use a catheter to detect abnormal electrical signals and then apply radiofrequency energy to remove scar tissue in the malfunctioning area.

Intradiscal electrical thermocoagulation (IDET) and percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) have been used to treat primary discogenic back pain, mostly pain derived from internal disk disruption and annular tears.

Unlike conventional coils, a plasma can be turned on and off, eliminating electrical interactions between coils, and enabling radiofrequency-invisibility when desired.

Initially, almost 15 years ago, the electrical isolation of PV was performed applying radiofrequency energy, very close to the ostium, but 7 8 years ago the majority of centers began avoiding this technique and radiofrequency energy is now applied outside the ostium of PV thus reducing the risk of pulmonary vein stenosis (PVS) in long-term follow-up.

The selective-field radiofrequency device Vanquish ®, using electromagnetically induced rapid oscillations of electrical dipoles to heat up the fatty tissue, is increasingly being used for reduction of subcutaneous abdominal fat.
