    摘要： Methods, devices and systems facilitate intermittent and/or partial obstruction of a pyloric valve. Devices generally include a support portion for preventing the device from passing through the pyloric valve and a tissue engagement portion for contacting tissue adjacent the pyloric valve to obstruct the valve. Some embodiments also include a positioning member extending from the tissue engagement portion for helping position the device for obstructing the valve. A retaining member may optionally be included on the distal end of the positioning member for further maintaining a position of the device in the stomach. Some embodiments are deliverable into the stomach through the esophagus, either by swallowing or through a delivery tube or catheter. Some embodiments are fully reversible. Some embodiments self-expand within the stomach, while others are inflated or otherwise expanded.

    摘要： A tissue ablation system for treating fibrillation in a patient comprises a steerable interventional catheter having an energy source that emits a beam of energy to ablate tissue thereby creating a conduction block for aberrant electrical pathways. The system also includes a handle disposed near a proximal end of the interventional catheter and has an actuation mechanism for steering the interventional catheter. A console allows the system to be controlled and provides power to the system, and a display pod is electrically coupled with the console. The display pod has a display panel to display system information to a user and allows the user to control the system. A catheter pod is releasably coupled with the handle electrically and mechanically, and also electrically coupled with the display pod.

    摘要： A tissue ablation method for treating atrial fibrillation in a patient comprises locating an ostium of a pulmonary vein and positioning an interventional catheter adjacent the ostium. The interventional catheter has an energy source. Collateral tissue adjacent the ostium is located and tissue around the ostium is ablated with energy from the energy source so as to form a contiguous lesion circumscribing the ostium. The lesion blocks aberrant electrical pathways in the tissue so as to reduce or eliminate the atrial fibrillation. The ablating is modified so as to avoid ablating or otherwise damaging the collateral tissue.

    摘要： Systems and methods for ablating tissue include an ablation device having an energy source and a sensor. The energy source provides a beam of energy directable to target tissue, and the sensor senses energy reflected back from the target tissue. The sensor collects various information from the target tissue in order to facilitate adjustment of ablation operating parameters, such as changing power or position of the energy beam. Gap distance between the energy source and target tissue, energy beam incident angle, tissue motion, tissue type, lesion depth, etc. are examples of some of the information that may be collected during the ablation process and used to help control ablation of the tissue.

    摘要： Echo-anatomically mapping tissue includes advancing a catheter having an ultrasound transducer toward tissue. A console adjacent the proximal end of the catheter controls catheter movement, and the ultrasound transducer senses tissue. First and second regions of the tissue are ultrasonically sensed while moving the ultrasound transducer along first, and second sensing patterns, respectively. A first 3-dimensional surface map of the first region, and a second 3-dimensional surface map of the second region are generated. The 3-dimensional surface maps are combined to form a combined surface map. Anatomical features may be identified in the first or second sensed regions. The tissue may be ultrasonically ablated while moving the ultrasound transducer along a first ablation path. The first ablation path may form a lesion around the identified anatomical features, and may be selected from a catalog of ablation paths or it may be prescribed by a physician.
