Patent number: 9585977Abstract: Methods and devices for treating skin include a skin-contacting portion, an actuator and a processor, wherein activation of the actuator causes surface acoustic waves of Rayleigh, “pseudo” Rayleigh types to be produced on the skin around the actuator. In a location which is under the actuator, the actuator produces tension and repulsion of skin particles. These surface acoustic waves can be used to provide treatment to the skin, including wound healing, non-adhesion of bandages, reduced infection, reduced pain and cosmetic enhancements. The skin-contacting portion may be a patch or bandage, a glove, a hand-held device, or any other suitable configuration. The actuator is incorporated into the skin-contacting portion.Type: GrantFiled: February 26, 2007Date of Patent: March 7, 2017Assignee: NANOVIBRONIX, INCInventors: Jona Zumeris, Harold Jacob, Hanan Raskin, Gera Kratysh, Yanina Zumeris

Patent number: 9579026Abstract: 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) can direct light to a photoacoustic transducer material that provides ultrasonic imaging energy. Returned ultrasound can be sensed by an FBG sensor. A responsive signal can be optically communicated to the proximal end of the guidewire, and processed such as to develop a 2D or 3D image. In an example, the guidewire outer diameter can be small enough such that an intravascular catheter can be passed over the guidewire. To minimize the size of the guidewire, an ultrasound-to-acoustic transducer that is relatively insensitive to the polarization of the optical sensing signal can be used. The ultrasound-to-optical transducer can be manufactured so that it is relatively insensitive to the polarization of the optical sensing signal.Type: GrantFiled: July 10, 2015Date of Patent: February 28, 2017Assignee: Vascular Imaging CorporationInventors: Michael J. Eberle, Diana Margaret Tasker, Howard Neil Rourke

Patent number: 9538952Abstract: Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a membrane can be sealed over a digit extension to form a closed volume. The closed volume can be inflated via an inflation tube, and a reference pattern can be disposed within the closed volume along with a measurement assembly. In use, a user can put on the glove, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the rectal wall, optical fibers in the measurement assembly can move relative to a reference pattern, and a controller can sense light reflected through the fibers from the reference pattern. The controller can calculate or estimate various attributes of the prostate based on the reflected light, such as the palpable surface width or volume.Type: GrantFiled: October 30, 2012Date of Patent: January 10, 2017Assignee: MedicaMetrix, Inc.Inventor: Christopher LaFarge

Patent number: 9387344Abstract: The disclosure discusses methods for determining absorbed dose information. A tomography imaging device generates an anatomy image relating to anatomy of a particular patient. A tomography imaging device also generates multiple radioactivity images regarding radioactivity distribution of an internally administered pharmaceutical over time in the particular patient. The radioactivity images related to the radioactivity distribution over time are registered. Each radioactivity image is combined with each anatomy image to create activity images. A Monte Carlo simulation for each activity image is run to obtain absorbed dose-rate images of the pharmaceutical at multiple times. The absorbed dose-rate images are integrated over time to obtain a total absorbed dose image. The absorbed dose-rate images and the total absorbed dose image are used to obtain a biologically effective dose (BED) image. The BED image is used to obtain an equivalent uniform does (EUD) of BED values for a chosen anatomical region.Type: GrantFiled: November 21, 2007Date of Patent: July 12, 2016Assignee: THE JOHNS HOPKINS UNIVERSITYInventors: George Sgouros, Hong Song, Andrew Prideaux, Robert Hobbs

Monitoring thermal conditions to vary operation of an ultrasonic needle tip of a surgical instrument
Patent number: 9387122Abstract: A method and apparatus to operate a surgical instrument in response to a thermal condition being detected that warrants curtailment of further operation. When the thermal condition is reached, command signals are generated that cause a needle of the surgical instrument to either have its vibrational speed slowed, have its vibrational movement stopped, or have it withdrawn from its relative position. The detection is of infrared radiation wavelengths and is carried out with either a thermal imaging device of a thermal recognition device. A corresponding temperature of the detected infrared radiation wavelengths is compared to a critical temperature to determine whether the thermal condition has been reached.Type: GrantFiled: January 4, 2011Date of Patent: July 12, 2016Assignee: Novartis AGInventor: Richard J.
