Abstract:
The present invention relates to a new forward-looking ultrasound device including a local actuator embedded inside an elongate member such as a guide wire or catheter. The present invention includes an ultrasound transducer element configured to engage with the local actuator and rotate about an axis of rotation at least when the ultrasound transducer element and the local actuator are engaged. Also disclosed are methods of using the same.
Abstract:
The present invention generally relates to methods, devices and systems for determining the rotational orientation of a device. The invention can involve providing a device comprising a plurality of markers, wherein each marker within the plurality of markers differs from an adjacent marker by size, shape, and/or position on the device. The invention can also involve inserting the device into a vessel and imaging the device to capture an image of the device in an imaging plane. The invention can further involve processing the captured image to determine an orientation of the device relative to the imaging plane based on the markers.

Abstract:
A system is provided for aortic valve imaging utilizing forward looking imaging sensors. A method of imaging the aortic valve is provided that can be utilized for diagnostic evaluation and the delivery of a therapy. In one form, the imaging system can be used to place a replacement aortic valve. In another aspect, an imaging system is combined with a valve replacement delivery system.
