For all 3 machines, a higher aspiration flow rate resulted in a cooler tip.
We routinely used a cool-tip needle (Radionics Corp., Burlington, MA, USA) while performing PRFA.
The RFA system (Model VIVA RF Generator, STARmed Co. Ltd., Goyang, Gyeonggi, Republic of Korea) included a cool-tip RF electrode (Model 17-20V15-40, STARmed Co). and an RF generator for providing an adjustable RF output power ranging from 0 to 200 W, with an operation frequency of 480 kHz.
They're on a definite proto-Scandi cool tip.
Once cool, tip into a bowl, cover and leave to infuse in the fridge overnight.
Generally, RFA was performed with the patients under local anesthesia and real-time ultrasonographic guidance by using the RITA system (RITA Medical Systems Inc., Mountain View, CA, n = 14) or Cool Tip system (Valleylab, Boulder, CO, USA, n = 41).
A 15-gauge multitined expandable RF needle electrodes (Leveen CoAcces needle, Boston Scientific, Nattick, MA) was used in all patients excepted 3% of patients treated with a straight cooled tip needle (Covidien, Boulder, CO).
With these cool tips you'll go from cold feet to a crotch meet 'n' greet.
Under fluoroscopic CT guidance, a 17G cool-tip electrode (Valleylab, Covidien, Boulder, CO) was placed centrally into the mass.
Radiofrequency ablation with US guidance was performed under general anaesthesia, using a 3.5-MHz probe with an incorporated guide and a 17-gauge cooled-tip electrode (Cool-Tip; Valleylab, Burlington, MA) with a 3-cm exposed portion.
