Abstract
An ablating device has a cover which holds an interface material such as a gel. The cover contains the interface material during initial placement of the device. The ablating device may also have a removable tip or a membrane filled with fluid. In still another aspect, the ablating device may be submerged in liquid during operation.
Claims59
A method of ablating tissue, comprising the steps of:
- providing an ablation device having an ablating element;
- positioning the ablating device against a target tissue;
- emitting energy from an emitter so that the energy passes through the target tissue;
- measuring the energy which passes through the target tissue with a receiver;
- and
- ablating the target tissue with the ablating element.
A device for ablating a target tissue, comprising:
- a plurality of ablating elements;
- an emitter which emits energy toward the target tissue;
- a receiver which receives energy transmitted through the target tissue;
- a control system coupled to the ablating elements, the emitter, and the receiver, the control system determining a change in an energy characteristic of the energy transmitted from the emitter to the receiver.
A method of ablating cardiac tissue, comprising the steps of:
- providing an ablating device having at least one ablating element, the ablating element having a focus;
- positioning the ablating device on a epicardial surface, wherein the focus is positioned at an angle with respect to the epicardial surface;
- and
- ablating tissue with the ablating element with the device positioned on the epicardial surface to form a first lesion.
A device for ablating tissue, comprising:
- a shaft;
- and
- a plurality of ablating elements coupled to the shaft, the plurality of ablating elements being configured to produce a continuous lesion in a target tissue.
A method of ablating cardiac tissue, comprising the steps of:
- providing an ablating device having at least one ablating element;
- positioning the ablating device on a epicardial surface;
- ablating tissue with the ablating element with the device positioned on the epicardial surface to form a first lesion;
- moving the ablating element to a new position;
- and
- ablating tissue to form a second lesion at the new position which is continuous with the first lesion.
