  • Patent number: 11826162
    Abstract: A variety of medical and non-medical devices are exploited by users to address a wide range of conditions. However, in the vast majority of instances, the device has a limited number of options with respect to its fit for the user and its performance. Further, the determination of target performance and fit are established on a qualitative basis rather than a quantitative basis. In many instances, these combinations lead to low user acceptance of the device due to the resulting performance and fit issues. Accordingly, it would enhance performance and user acceptance if a quantitative determination provided a recommended type where options exist, and this determination provided the basis of a custom designed device to the user's specific anatomical and/or performance requirements.

  • Patent number: 11397486
    Abstract: Ultrasonic force detection systems and methods can be based on propagation of ultrasonic waves in a user's body (e.g., in a user's digit). An amount of force can be determined using time-of-flight (TOF) techniques of one or more ultrasonic waves propagating in the user's body. In some examples, an electronic device including a transducer can be coupled to a digit, and can transmit ultrasonic waves into the digit. As the wave propagates through the thickness of the digit, a reflection of at least a portion of the transmitted wave can occur due to the bone and/or due to reaching the opposite side of the digit (e.g., finger pad). One or more reflections can be measured to determine the amount of force.

  • Patent number: 9936896
    Abstract: Registration is provided for imaging with an intra-patient probe. The intra-patient probe is used for imaging or the imaging is, at least in part, of the intra-patient probe. Either approach for imaging with an intra-patient probe uses active transitions for registration. In one embodiment, one or more markers in the intra-patient probe are moveable relative to the intra-patient probe, allowing avoidance of occlusions and providing more reliable marker detection for registration. In another embodiment, a value of a parameter for imaging with at least one modality is changed so that acceptable or better registration with an image of another modality may be made. The imaging is repeated with differences, such as field-of-view or scale, allowing for registration for different types of modalities.

  • Patent number: 9884150
    Abstract: A system for identifying an attribute of an implanted medical device, such as an access port is disclosed. In one embodiment, the identification system comprises a marker included with the implanted medical device, wherein the marker relates to an attribute of the implanted medical device. An external detection device is also included, comprising a signal source that emits an incident electromagnetic signal for impingement on the marker of the implanted medical device, a detector that detects a return signal from the marker resulting from impingement of the incident electromagnetic signal, and a user interface for conveying information relating to the attribute based on detection of the return signal. In the case of an implantable access port, for instance, the described system enables information, such as the ability of the port to withstand power injection of fluids therethrough, to be ascertained even after the port has been subcutaneously implanted within the patient.

  • Patent number: 9610063
    Abstract: A system and method for improved ultrasound strain imaging includes using data from a tracking system to enhance the quality of ultrasound strain image and to reduce the dependency of image quality of the user's expertise. The tracking information is synchronized with the RF frames and interpolated to find the transformation corresponding to each frame. The RF frames with their transformations are incorporated into calculation of ultrasound strain images. The tracking system may be an optical tracker, electromagnetic tracker, accelerometer, or a structured light system. The structured light system may also be used for probe calibration, by calibrating the surface of the probe pre-operatively. In addition, a relative Young's Modulus may be calculated using tracking information that is independent from the distribution of input force.

  • Patent number: 9554815
    Abstract: Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device includes three balloons that are each sized and shaped to fit within a concave portion of a valve cusp when inflated with a liquid and a shock wave source within each of the three balloons. Each balloon is separately and/or independently inflatable, and each shock wave source is separately and/or independently controllable. Methods of treating calcified heart valves using a shock wave device can include advancing a shock wave device having one or more balloons and a shock wave source in each of the balloons to contact a heart valve, inflating the one or more balloons with a liquid such that the balloon is seated within a concave portion of a valve cusp, and activating the shock wave source.

  • Patent number: 9265973
    Abstract: An ultrasonic probe that transmits an ultrasonic vibration, generated in an ultrasonic vibrator, from a proximal end to a distal end so that the ultrasonic probe performs a longitudinal vibration in a vibrating direction. The ultrasonic probe including a probe body, a distal asymmetric portion, and a proximal side probe component. The distal asymmetric portion is asymmetric about an X-axis so that a center of gravity of the distal asymmetric portion is deviated from the X-axis and a first lateral vibration of the distal asymmetric portion is superposed on the longitudinal vibration of the ultrasonic probe. The proximal side probe component is bent relative to the probe body at a bending position so that a center of gravity of the proximal side component is deviated from the X-axis and a second lateral vibration of the proximal side component is superposed on the longitudinal vibration of the ultrasonic probe.

  • Patent number: 9254211
    Abstract: A thin-walled guide wire tube is fixedly and sealably attached to both a proximal section and a distal section of a balloon angioplasty catheter. A stent is co-axially mounted onto the inflatable balloon of the balloon angioplasty catheter. Because the guide wire tube forms an inner liner for the balloon angioplasty catheter, the fluid inflation lumen of the catheter is sealed so the inflation liquid that pressurizes the balloon will not leak as it would be if there were no “inner liner” and the balloon angioplasty catheter were attached to the guide wire itself. By not having a traditional inner shaft through which a conventional guide wire slides, the deflated balloon on which the stent is mounted can have a reduced diameter.
