A method and apparatus that utilizes a force-time integral for real time estimation of lesion size in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and integrates the force over an energization time of the ablation probe. The force-time integral can be calculated and utilized to provide an estimated lesion size (depth, volume and / or area) in real time. The force-time integral may also account for variations in the power delivered to the target tissue in real time to provide an improved estimation of the lesion size. In one embodiment, the force metric can be used as feedback to establish a desired power level delivered to the probe to prevent steam popping.

A frame ensures that the alignment between a high intensity focused ultrasound (HIFU) transducer designed for vaginal use and a commercially available ultrasound image probe is maintained, so that the HIFU focus remains in the image plane during HIFU therapy. A water-filled membrane placed between the HIFU transducer and the treatment site provides acoustic coupling. The coupling is evaluated to determine whether any air bubbles exist at the coupling interface, which might degrade the therapy provided by the HIFU transducer. HIFU lesions on tissue appear as hyperechoic spots on the ultrasound image in real time during application of HIFU therapy. Ergonomic testing in humans has demonstrated clear visualization of the HIFU transducer relative to the uterus and showed the potential for the HIFU transducer to treat fibroids from the cervix to the fundus through the width of the uterus.

A methodology is disclosed that enables the delay stages of an analog delay locked loop (DLL) or phase locked loop (PLL) to be programmed according to the operating condition, which may depend on the frequency of the input reference clock. The resulting optimized delay stages allow for a broad frequency range of operation, fast locking time over a wide range of input clock frequencies, and a lower current consumption at high clock frequencies. Better performance is achieved by allowing the number of analog delay stages active during a given operation to be flexibly set. The deactivation or turning off of unused delay stages conserves power at higher frequencies. The high frequency range of operation is increased by using a flexible number of delay stages for various input clock frequencies. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
