Ablation Catheters. Cerablate ® easy / Cerablate ® easy TC Steerable RF Ablation and Mapping Catheter with integrated Temperature Sensor. CERABLATE ® easy is a steerable ablation catheter designed for radiofrequency ablation of cardiac tachyarrhythmias.
The catheter is intended for creating endocardial lesions during cardiac ablation procedures (mapping, stimulation, and ablation) for the treatment of typical atrial flutter. RF ablation has been performed safely at sites >8 mm below the coronary artery ostia with careful continuous monitoring of catheter position during the RF application. Standard RF ablation with tip temperature maintained at <55°C has been suggested to prevent aortic valve damage observed in animal studies. 80 Abstract.

US6312425B1 US09/515,382 US51538200A US6312425B1 US The purpose of this study was to directly compare lesion sizes created by cryoablation and irrigated RF under controlled conditions. METHODS AND RESULTS: Ablation lesions were created in freshly harvested porcine left ventricular myocardium in a blood-filled tissue bath using an 8-mm-tip cryoablation catheter and a 3.5-mm-tip open-irrigated RF ablation catheter. One study randomly assigned the enrolled patients to 3 groups: the pulmonary vein ablation catheter group, circular, irrigated mapping (nMARQ) CA group and TSA group ; the data from the pulmonary vein ablation catheter and nMARQ groups were combined during data extraction, as both of them used CA. Catheters are usually fitted for incontinence, or when patients have difficulty passing urine. According to Wellspect, this could be due to a variety of reasons, including kidney stones, an enlarged prostate gland or injury to the nerves of You may be in the position to have to use a catheter following surgery, or if you have issues with your prostate or problems with urinary retention.
Imricor's advances in cardiac catheter ablation highlight the RF ablation catheters, cryoablation catheters and diagnostic catheters for cardiac ablation, plus catheter accessories including leads, sheaths and needles.

The catheter tip is comprised of platinum-iridium and diamond components. A network of chemical vapor deposit (CVD) industrial diamonds acts as heat-shunting material. Distal diamond. Watch this video demonstration of a radiofrequency catheter ablation procedure. The procedure is performed by a heart rhythm specialist called an electrophys A typical RF ablation procedure can involve a preliminary electroanatomical and ECG mapping of the heart, followed by catheter placement to a target site, ablation with RF power monitoring and catheter tip temperature monitoring, followed by more ECG mapping and possible attempts to re-induce fibrillation to test the effectiveness of the treatment.

The ablation catheter is advanced through the transseptal sheath to the anterior-anterolateral mitral annulus, and delivery of RF lesions is started when the A/V ratio is 1 : 2. Linear ablation is then performed with counterclockwise rotation of the transseptal sheath and progressive release of the ablation catheter curve.

Endovascular cryoablation systems use a steerable ablation catheter that can be cooled to −70°C or lower, resulting in tissue necrosis with a similar lesion size to that attained with irrigated RF ablation catheters. 34 Commercially available systems cool the catheter tip by delivering nitrous oxide under pressure via a hollow injection tube that spans the length of the ablation catheter into a widened lumen at the catheter tip.
Radiofrequency (RF) ablation is a treatment modality that kills unwanted tissue by heat. RF ablation is now the treatment of choice for certain types of cardiac in the thermal strain curve as a function of heating time. Using a prototype intracardiac echocardiography (ICE) array for imaging and a catheter for RF ablation, 12 Feb 2014 The electrical activity of the heart − image taken from [ 2 ].
Se hela listan på emedicine.medscape.com The Therapy ™ Cool Flex catheter (Figure 1) is an entirely new concept in irrigated ablation catheters. It possesses a unique electrode design that allows the ablation tip to flex and compress to the motion of the heart. Irrigation is provided through dozens of slits that are uniformly spread throughout the electrode providing radial cooling. Cardiac Ablation - RF Ablation What is a Cardiac Ablation? A Cardiac Ablation is a procedure where catheters are placed in the heart and radio frequency (RF) energy is delivered through the catheter to abnormal heart tissue that is causing an irregular heartbeat. The RF ablation catheter as in claim 1 wherein said first electrode is fixed and said second electrode is rotatable relative to said first electrode.
