  • Publication number: 20160361040
    Abstract: Provided is an ultrasound imaging apparatus that is cable of estimating a three-dimensional effect of a blood flow, by using blood-flow velocity information obtained by a color Doppler method, and presenting diagnostic information into which the three-dimensional effect is reflected. The ultrasound imaging apparatus of the present invention is provided with an ultrasound probe configured to transmit ultrasound waves to a test object and to receive echo signals reflected from the test object, and a signal processor configured to process the echo signals received by the ultrasound probe, and the signal processor estimates the three-dimensional effect of the blood flow velocity, from a difference between a first blood flow velocity estimated from the echo signals by a first method, and a second blood flow velocity estimated by a second method which is different from the first method, and generates diagnostic information into which the three-dimensional effect is reflected.

  • Publication number: 20160361041
    Abstract: Cardiac Output (CO) has traditionally been difficult, dangerous, and expensive to obtain. Surrogate measures such as pulse rate and blood pressure have therefore been used to permit an estimate of CO. MEMS technology, evolutionary computation, and time-frequency signal analysis techniques provide a technology to non-invasively estimate CO, based on precordial (chest wall) motions. The technology detects a ventricular contraction time point, and stroke volume, from chest wall motion measurements. As CO is the product of heart rate and stroke volume, these algorithms permit continuous, beat to beat CO assessment. Nontraditional Wavelet analysis can be used to extract features from chest acceleration. A learning tool is preferable to define the packets which best correlate to contraction time and stroke volume.

  • Publication number: 20160361064
    Abstract: Systems and methods disclosed stimulate nerve growth by applying a tensile (axial pulling) load on a proximal stump of the nerve. This load may be imposed once, at the time of repair. This implementation may be advantageously employed to remove tension away from the repair site, for any number of soft tissues, e.g., nerves, ligaments, tendons, and so on. Alternately, for a larger gap, by progressively elongating a nerve through tensile stimulation, the nerve may regenerate and be fully functional, particularly if elongated at a proper rate. After sufficient regrowth, nerve ends may be reattached, resulting in more complete functional recovery. Two implementations, which have been embodied in prototype devices, also include particularly useful features, one of which uses a screw and clamp with slotted insert design, and the other of which enables the use of sutures or straps to secure the tissue to the clamp.

    Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The recanalization catheter includes first and second mechanically actuatable wings positioned at a distal region of the elongate shaft of the catheter that are actuatable between a retracted position and an expanded position. In the retracted position the mechanically actuatable wings are positioned in first and second elongate channels defined in the elongate shaft, and in the expanded position the mechanically actuatable wings extend outward from the first and second elongate channels. The actuatable wings extend in an arcuate path away from the elongate shaft in the expanded position to be positionable in a circumferential orientation within a subintimal space formed in a vessel wall to automatically orient a lateral port of the elongate shaft toward the true lumen.

  • Publication number: 20160361077
    Abstract: A method for increasing or restoring a flow in a body lumen can treat conditions related to a stroke, such as an ischemic stroke, by removing an occlusion from a blood vessel and/or reopen a blood vessel. The method makes use of a device that includes a central wire, a pusher tube, a distal structure, and a proximal structure into the blood vessel, in which the distal structure is closed at its proximal end. A clot or occlusion present in the body lumen such as an artery may be engaged in and/or between the distal and proximal engaging elements. Further, the positions of one or both of the engaging elements and the distance between them can be adjusted to ensure the engagement of the clot or occlusion.

  • Publication number: 20160361078
    Abstract: This invention relates to oral debris extractors and devices for the removal of oral debris from an oral cavity of humans or mammals. Oral debris extractors include tonsil stone extractors for removal of tonsilloliths and tonsil stones in an oral cavity as well as extractors for removal of other types of oral debris present in an oral cavity. The invention relates to uses of oral debris extractor devices to remove all types of oral debris from the oral cavity of humans or mammals as well as for use to explore and assess the presence of oral debris and tonsil stones in the oral cavity and in the tissues of the oral cavity. Methods of using an oral debris extractor device to explore the oral cavity and to remove oral debris are also described. The oral debris extractor is hand-held and does not require any external power source or battery to be operated. A curved shaft provides ergonomic and other advantages. The oral debris extractor can be manufactured using recyclable materials.

  • Publication number: 20160361079
    Abstract: A surgical handheld instrument for grasping an object includes two lever elements, each lever element having a grip portion and a jaw portion. A lever joint connects the two lever elements rotatably to each other between their grip portion and their branch portion. Each of the two grip portions is adjoined by a respective spring portion for connecting the two grip portions such that the two lever elements are held resiliently in an open position. To create an easily manageable, elegant and releasable connection for spring ends on surgical instruments, the handheld instrument includes a hinge pin at a free end of one spring portion and a bearing eye at a free end of the other spring portion. The bearing eye has a longitudinal slit for radial insertion of the hinge pin into the bearing eye.

  • Publication number: 20160361080
    Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the surgical device includes a handle, an elongate inner sheath and a circular cutting blade that extends from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the surgical device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade.

    Abstract: A surgical instrument for cutting and coagulating tissue is provided that includes an elongate sheath and an ultrasonic blade. In one embodiment, an ultrasonic blade is positioned within a sheath such that movement of the sheath relative to the blade results in the dissection and/or coagulation of tissue therebetween. In another embodiment, an ultrasonic blade is positioned within a sheath such that movement of the blade relative to the sheath results in the dissection and/or coagulation of tissue therebetween. The size and shape of distal ends of the blade and sheath determine the size and shape of the tissue being cut and/or removed from a body.
