2. removal, especially by cutting with a laser or electrocautery.
catheter ablation radiofrequency ablation.
endometrial ablation removal of the endometrium; methods used include radiofrequency, electrical energy, lasers, and hot and cold liquids.
radiofrequency ablation (radiofrequency catheter ablation) destruction of an accessory conduction pathway or other troublesome area of dysrhythmia by means of unmodulated high frequency alternating current delivered by a bipolar or unipolar catheter. The current causes heat with tissue destruction and formation of scar tissue to block the pathway or dysrhythmic area. Transvenous radiofrequency ablation has been successful in treatment of supraventricular tachycardia and is an attractive option to surgery. Called also catheter ablation.

Patient discussion about ablation

Q. SVT and AF, Hearts that go fast to slow or any others probs with the beats of any kind and Ablation of hearts I have had Ablation done once and I am still having passing out spells and still on 50mg toprol 2 times a day till two days ago, now I am on 150 to 200 aday again. Its not the first time I have had to up meds. I had ablation down 4/22/05. I can breath better now but but it didnt take it away as you can tell. Now Dr Leonardie would like to do it again . This is the big ????! Will it or can it work 100% this time, or will it hit and miss some again???? MTT

"We're working to demonstrate the safety of the new system by quantitatively understanding how much impact damage can occur during ascent from possible impact scenarios, including smaller pieces of insulating foam, ablator materials found on the external tank and solid rocket boosters, and ice that can form on the shuttle components due to the cryogenic fuels," he says.
Additionally, impact tests have been performed with a number of other potential impact materials that can damage the Shuttle during ascent including ice, ablator, and metal.
