    Abstract: Devices and methods for obtaining a real-time, three-dimensional image of a body part, particularly a blood vessel. A catheter has a chamber in its tip. The chamber contains an ultrasound transducer and reflector which generally face each other and rotate about a common axis. The transducer element on the transducer and the reflective face on the reflector are both tilted off-axis. The difference in angular velocity generally creates a phase shift between the transducer and the reflective face. The phase shift allows the transducer and the reflective face to actively scan a three-dimensional volume that is generally bounded interiorly by a hyperboloid and exteriorly by the effective range of the ultrasound beam. The transducer and reflector may rotate at constant speeds or nonconstant speeds as well in the same direction or in opposite directions.

  • Patent number: 10123685
    Abstract: An apparatus includes a power source, a pulse generator, a light source, a guidewire, an optical fiber, and a connector. The pulse generator is in electrical communication with the power source. The pulse generator is also capable of generating an electric pulse. The light source is in electrical communication with the pulse generator in such a way that the light source turns on and off in response to the electric pulse received from the pulse generator. The guidewire includes a proximal end and a distal end. The optical fiber extends through the guidewire from the proximal end of the guidewire towards the distal end of the guidewire. The connector couples with the guidewire while allowing the light source to communicate with the optical fiber.

    Abstract: Disclosed are devices, systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes located on one or more catheters and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.
