Definitions
- catheters are used in various procedures, both diagnostic and therapeutic.
- One general type of catheter used for both diagnostic and therapeutic applications is a cardiac electrode catheter.
- the diagnostic uses for a cardiac electrode catheter include recording and mapping of the electrical signals generated in the course of normal (or abnormal) heart function.
- Therapeutic applications include pacing, or generating and placing the appropriate electrical signals in order to stimulate the patient's heart to beat in a specified manner, and ablation.
- ablation procedure electrical or radio-frequency energy is applied through an electrode catheter to form lesions in a desired portion of the patient's heart, for example the right atrium.
- arrhythmias such as supra- ventricular tachycardia, ventricular tachycardia, atrial flutter, atrial fibrillation, and other arrhythmias.
- FIGS. 1 A to 1C are three perspective views of a portion of a telescoping tip electrode catheter with a steerable portion of the main catheter body just proximal of the telescoping tip portion according to an embodiment of the present invention
- FIG. 9 is a partial cross section of the telescoping tip electrode catheter showing the steering cables and the steerable catheter portion engaged in a curve according to the FIGS. 1 A to IC embodiments;
