  • Patent number: 9474506
    Abstract: An intravascular ultrasound catheter system is provided and enables a simplified, economical technique for ultrasound visualization of a blood vessel. The catheter may include a park ablation system for crossing chronic total occlusions and severe stenoses. The catheter is advanceable and is oriented entirely under manual control of the clinician and the application of radiofrequency energy for spark erosion of the stenosis also is controlled manually by the clinician. The system enables the clinician to observe an ultrasound image sufficiently to determine where to orient the ablation electrode so as to reduce the risk of dissection or perforation of the blood vessel. The ultrasound image is generated in response to manual rotation of the catheter and the ablation spark is generated only when the physician is satisfied as to the orientation of the electrode within the vessel.

  • Patent number: 8038618
    Abstract: An ultrasound-imaging system and method is provided that permits an operator to acquire an image of a volume-of-interest in a time critical fashion, that is capable of referencing the volume rendering to a standard two-dimensional imaging mode, and permits the operator to selectively choose a number of display-mode parameters that result in an operator directed view of the volume-of-interest. The ultrasound-imaging system comprises an input device configured to receive a plurality of imaging parameters and a controller in communication with the input device. The ultrasound-imaging system generates an operator-directed transmit-beam scan sequence in response to the imaging parameters and transmits a spatially modified transmit-beam scan sequence over a portion of the volume-scan range of the ultrasound-imaging system. Moreover, the ultrasound-imaging system provides the flexibility for an operator to direct a plurality of operator-configurable multi-dimensional views.

  • Patent number: 6894425
    Abstract: A two-dimensional ultrasound phased array transducer includes an acoustic backing, a first circuit, which may be a flexible circuit disposed over the acoustic backing or a ground plane, an acoustically absorptive interface layer disposed over the flexible circuit, and a piezoelectric layer disposed over the interface layer. A matching layer may be disposed over the piezoelectric layer, and a second circuit, which may be a ground plane or a flexible circuit, may be disposed over the matching layer. The piezoelectric layer and the matching layer are diced by forming kerfs extending through these layers and at least partially into the interface layer. Extending the kerfs into the interface layer reduces cross-talk between elements, electrically isolates the elements, and facilitates manufacturing by reducing the precision required in controlling the depth of the cut.

  • Patent number: 6625854
    Abstract: An acoustic backing element includes a glass fiber epoxy composite planar substrate to the outer major surfaces of which are applied electrically conductive material. The electrically conductive material may be a conductive layer that is etched to expose electrical contact material in the form of conductive traces. Each conductive trace provides electrical connection between a transducer element and electrical control circuitry typically located on an electrical circuit board. The acoustic backing element provides precisely located electrical contacts for connecting the transducer elements to their control circuitry, while simultaneously providing superior acoustic attenuation. In addition, the thermal coefficient of expansion (TCE) of the glass fiber epoxy composite material comprising the planar substrate can be closely matched to the TCE of the electrical contact material.

  • Patent number: 6497667
    Abstract: An ultrasonic transducer probe uses one or more ribbon cables to attach the transducer elements to the probe wiring. Electrical conductors within a first ribbon cable attach to corresponding lands on an end of an integrated circuit and, electrical conductors within additional ribbon cables attach to corresponding lands on circuit boards. The circuit boards distribute the electrical signals from the attached ribbon cables to additional lands on another end of the integrated circuit.

  • Patent number: 6488664
    Abstract: A clamp for a tube having particular application to a nose trumpet for use with a transnasal TEE probe. The clamp includes a generally circular band for encircling the tube and a tongue disposed on one end of the band and a pair of jaws disposed on the other end. The tongue is adapted to penetrate the space between the pair of jaws. Teeth disposed on the upper surface of the tongue are adapted to mesh with teeth disposed on the lower surface of the upper jaw to prevent withdrawal of the tongue. A pair of handles extend outwardly away from the interior of the band and are adapted to be pushed toward one another to cause penetration of the tongue and into the jaws. An arm hinged to the band is affixed to the upper jaw and upon pivoting of the arm, the upper jaw is lifted away from the tongue to disengage the teeth.

  • Patent number: 6368281
    Abstract: A two-dimensional phased array ultrasound transducer comprises a transducer housing, a sensor mounted within the housing, and a convex environmental barrier for placement against, and maximizing contact with, a patient's body. The environmental barrier does not necessarily provide any focusing capability, therefore the propagation velocity of sound through the environmental barrier is approximately equal to the propagation velocity of sound through tissue of the patient's body.

  • Patent number: 5853368
    Abstract: A catheter apparatus having a main catheter body with an ultrasound transducer mounted into a side of the catheter body proximate to its distal end providing a field of view from the side of the catheter. Mounted axially on the same side of the catheter body is a independently-controllable treatment structure having a deployable segment with a therapeutic segment proximate with its distal end and having a range of movement along a predetermined path including locations only within the imaging field. The location of the treatment structure's therapeutic segment is determinable relative to the ultrasound transducer, enabling accurate and repeated positioning of the therapeutic segment at a desired location within the imaging field where it can be imaged clearly. The treatment structure bends only at the deployable segment, which includes deflection bands connected to an articulation mechanism in a handle.

  • Patent number: 5846204
    Abstract: An ultrasound catheter including a flexible, torsionally-rigid elongate transducer cable having proximal and distal ends, with a transducer housing fixably connected proximate to the distal end. An ultrasound transducer, having a substantially planar surface and a scan plane substantially perpendicular to the planar surface, is fixably connected to a first side of the transducer housing to provide a predetermined two-dimensional cross-sectional image corresponding to an angular position of the ultrasound transducer. The transducer generates a series of successive two-dimensional cross-sectional images. In one embodiment, the ultrasound transducer is a linear array transducer which produces a substantially rectangular scan plane. A guide wire sleeve which is fixably connected to a second side of the housing substantially opposing the first side, causes the transducer to follow a predetermined rotational path around the guide wire when a torque is applied to the proximal end of the transducer cable.
