Abstract
A method of thermal ablation using high intensity focused ultrasound energy includes the steps of positioning one or more ultrasound emitting members within a patient, emitting ultrasound energy from the one or more ultrasound emitting members, focusing the ultrasound energy, ablating with the focused ultrasound energy to form an ablated tissue area and removing the ultrasound emitting member.
Claims26
A method of performing an ultrasound ablation procedure on a heart of a patient, comprising:
- providing a tissue-engaging device;
- engaging the heart with the tissue-engaging device;
- positioning the heart into a non-physiological orientation;
- adjusting the beating of the heart;
- positioning a portion of an ultrasound ablation device through a mouth of the patient;
- and
- performing an ultrasound ablation procedure on the heart.
4 more elements
A system of ablating a heart of a patient comprising:
- a tissue engaging device configured to engage the heart and position the heart in a desired orientation to a desired location in a body cavity of the a patient;
- a stimulator configured to deliver stimulating energy to the heart, altering a heart rate of the heart upon receipt of the stimulating energy;
- an ablation device configured to generate the ablation energy a predetermined distance from ablation device, configured to be introduced to the location of the body cavity through a mouth of the patient and configured to focus the ablation energy at the predetermined distance to adequately deliver the ablation energy from the location in the body cavity to the heart;
- and
- a controller, operatively coupled to the ablation device and to the stimulator, the controller being configured to synchronize delivery of the stimulating energy to the heart via the stimulator and the ablation energy to the heart via the ablation device.
