摘要: An imaging guidewire can include one or more optical fibers communicating light along the guidewire. At or near its distal end, one or more blazed or other fiber Bragg gratings (FBGs) directs light to a photoacoustic transducer material that provides ultrasonic imaging energy. Returned ultrasound is sensed by an FBG sensor. A responsive signal is optically communicated to the proximal end of the guidewire, and processed to develop a 2D or 3D image. In one example, the guidewire outer diameter is small enough such that an intravascular catheter can be passed over the guidewire. Techniques for improving ultrasound reception include using a high compliance material, resonating the ultrasound sensing transducer, using an attenuation-reducing coating and/or thickness, and/or using optical wavelength discrimination. Techniques for improving the ultrasound generating transducer include using a blazed FBG, designing the photoacoustic material thickness to enhance optical absorption. Techniques for distinguishing plaque or vulnerable plaque may be used to enhance the displayed image.

摘要: A ultrasound platform is used to generate, process and display ultrasound images using a probe connected via a sterilizable connector. The probe is used to take ultrasound images, and can be a sterilizable finger mounted probe. The sterilizable connector includes a connector housing which has been sealed to prevent moisture from entering it, and a multi-wire cable which is electrically coupled to the probe at a first end and coupled to the connector housing at a second end. The multi-wire cable has its second end sealed with the connector housing to prevent moisture from entering the sealing between the multi-wire cable and the connector housing. A plurality of electrical contacts are formed on at least one surface of the sterilizable connector. A mating connector is used to electrically couple the sterilizable connector to a standard connector for directly connecting to the ultrasound platform. The mating connector has a plurality of mating contacts formed thereon for electrical coupling with the electrical contacts of the sterilizable connector. The sterilizable connector can be separated from the standard connector and the mating connector, such that the probe and the sterilizable connector can be sterilized.

摘要: This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.
