    摘要： Method and systems for optimizing acoustic energy transmission in implantable devices are disclosed. Transducer elements transmit acoustic locator signals towards a receiver assembly, and the receiver responds with a location signal. The location signal can reveal information related to the location of the receiver and the efficiency of the transmitted acoustic beam received by the receiver. This information enables the transmitter to target the receiver and optimize the acoustic energy transfer between the transmitter and the receiver. The energy can be used for therapeutic purposes, for example, stimulating tissue or for diagnostic purposes.

    摘要： Methods and systems for processing and/or superimposing a medical image of an anatomical body (e.g., a heart) with graphical information are provided. Reference elements and/or reference catheter are placed in contact with the anatomical body. A physical structure within a navigational coordinate system is located using the reference elements and/or reference catheter. An image reference within an image coordinate corresponding to the physical structure is located. Location of the image reference can be accomplished, e.g., by displaying the medical image and electronically marking the displayed image reference, or by automatically locating image data corresponding to the image reference. The navigational and image coordinate systems are then registered based on the location of the physical structure within the navigational coordinate system and the location of the image reference within the image coordinate system, which allows graphical information to be accurately merged with the medical image data.

    摘要： Methods and systems are provided for generating graphical representations of orifices and vessels. One method comprises generating a representation of the surface (e.g., an endocardial surface) within a coordinate system, and laterally moving the distal end of an elongated probe within an orifice (e.g., a valve or a vessel ostium) associated with the surface. The method further comprises defining line segments within the coordinate system while the probe distal end is moved within the orifice, wherein each of the line segments represents the probe distal end. The method further comprises defining intersection points within the coordinate system, wherein each of the points represents an intersection of one of the line segments and the surface representation. Lastly, the method comprises graphically generating a representation of the orifice based on the intersection points, e.g., by forming the orifice representation around the intersection points. Another method comprises moving the distal end of an elongated probe within the vessel, defining line segments within a coordinate system while the probe distal end is moved within the vessel, wherein each of the line segments represents the probe distal end, and graphically generating a representation of the vessel based on the line segments.

    摘要： A wireless cardiac stimulation device comprising an implantable transmitter module housing a transmitter and a separately implantable battery module housing a battery for powering the transmitter and other device electronics via a subcutaneously routable electrical cable connecting the module is disclosed. The transmitter module contains a transmitter enclosure which comprises one or more ultrasound transducers. Having separate transmitter and battery modules allows implantation of the transmitter module closer to the target receiver implanted in tissue. A discrete battery module also enables easy replacement of the battery without disturbing the transmitter, which is highly desirable.
