摘要： A transducer subassembly with combined imaging and therapeutic capabilities is disclosed. The subassembly includes heat sinks that are configured to maintain the transducer at a low operating temperature so that the transducer operates at high efficiency and also can handle a wider range of frequencies. The subassembly is also configured to allow cooling fluid to flow past the transducer element. One heat sink in the subassembly also acts as an acoustic matching layer and another heat sink acts as a backing. Alternatively, the second heat sink which acts as a backing is optional. The transducer is configured to transmit at one power level for imaging, and at a second power level for ablating. The transducer may comprise sub-elements transmitting at different power levels. The subassembly may be operated at one power level for imaging and a second power level for ablating.

摘要： An ablation system for treating atrial fibrillation in a patient comprises an inner shaft having proximal and distal ends as well as a lumen therebetween. A distal tip assembly is adjacent the inner shaft distal end, and the distal tip assembly comprises an energy source and a sensor. The energy source is adapted to deliver energy to a target tissue so as to create a zone of ablation in the target tissue. This blocks abnormal electrical activity and thus reduces or eliminates atrial fibrillation in the patient. The system also has an outer shaft with proximal and distal ends, and a lumen therebetween. The inner shaft is slidably disposed in the outer shaft lumen, and the inner shaft is rotatable, bendable and linearly slidable relative to the outer shaft. The outer shaft is rotatable, bendable and linearly slidable relative to the target tissue.

摘要： Systems and methods for noninvasive skin treatment and deep tissue tightening are disclosed. An exemplary method and treatment system are configured for controlled thermal energy delivery to treat subdermal regions of the skin. First, specific control parameters such as power, skin temperature, and ultrasound frequency are chosen so as to provide localized delivery of ultrasound to a region of interest. Then, ultrasound energy is delivered at a frequency, depth, distribution, timing, and energy density to achieve the desired therapeutic effect.

摘要： Methods and apparatus for treating a patient include an ablation device for treating atrial fibrillation. The device includes a housing having proximal and distal ends, and an energy source adjacent the distal end of the housing. The energy source has an active portion and an inactive portion. The active portion is adapted to deliver energy to tissue when the energy source is energized. This creates a partial or complete zone of ablation in the tissue that blocks abnormal electrical activity, thereby reducing or eliminating atrial fibrillation in the patient. The inactive portion does not emit energy or emits substantially no energy when the energy source is energized.
