Patent number: 9743991Abstract: A method for performing a medical procedure, includes coupling a tip of a probe to tissue in an organ of a patient in order to apply the medical procedure using the probe. A force exerted by the tip on the tissue and a displacement of the tip created by the force are measured. A dependence of the force on the displacement is calculated. Based on the calculated dependence, a risk level of perforation of the tissue is estimated.Type: GrantFiled: October 21, 2013Date of Patent: August 29, 2017Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Doron Moshe Ludwin, Eitan Peri, Eyal Yechezkel Glottmann, Yevgeny Bonyak, Aharon Turgeman

Patent number: 9730605Abstract: A system and method is disclosed for measuring muscle reflexes (e.g., a bulbocavernosus reflex) as a tool for identifying/diagnosing dysfunctions (e.g., spinal cord abnormalities, bladder voiding dysfunction, and sexual organ dysfunction) non-invasively by using mechanical stimulation. The system and method includes a probe having a predetermined patient contacting portion, wherein when the contacting portion is moved into contact with a particular area of the patient (e.g., the patient's genitals), the contact induces a muscle reflex. The probe detects the pressure resulting from the contacting portion being abruptly and forcibly brought into contact with the particular area. Such detection is used to electronically initiate capture of electrical responses from a plurality of electrodes placed on the patient's skin in proximity to the particular area. Such electrical responses are processed to determine characteristics of the patient's reflexes of one or more muscles adjacent to the electrodes.Type: GrantFiled: July 19, 2016Date of Patent: August 15, 2017Assignee: Uroval, Inc.Inventors: Debra J. Folkerts, Karen Louise Finstrom McPhee, Gregory Ray Johnson, Timothy Martin Gack

Patent number: 9566004Abstract: Provided herein are systems and methods that use a video content analysis algorithm to measure and quantify repetitive motion activity of a designated body part, including velocity, acceleration, frequency, and duty cycle, without applying sensors or other instrumentation to the body, for the purpose of preventing repetitive motion injuries. In some embodiments, the video-based direct exposure assessment system uses marker-less video and a video content analysis algorithm. The video content analysis algorithm is able to recognize and identify the pattern of repetitive motion, through a process known as cyclic motion analysis. Determination of the cycle pattern provides parameters for determining a body part's activity level, and thereby allows determination of the body part's activity level.Type: GrantFiled: November 20, 2012Date of Patent: February 14, 2017Assignee: KINEVID, LLC.Inventors: Robert G.

Patent number: 9521965Abstract: An unmet need of orthopedic practitioners is a clinically-relevant measurement device and technique to objectively quantify joint (e.g., knee) stability, including rotational stability. An apparatus and method is disclosed for performing a mechanical joint movement test, such as a knee pivot shift test, through the application of standardized dynamic loads (e.g., using a constant-tension spring or other mechanism). When used for knee evaluation, this test reliably induces the characteristic “pivot” tibial subluxation/reduction event in an ACL-deficient knee, allowing for more sensitive detection of deficiencies in rotational knee stability, quantification of the relative importance of knee stabilizers, and comparison of the performance of contemporary ACL reconstruction techniques. The test allows for better understanding joint biomechanics and for defining unique kinematic and kinetic signatures for common joint injuries, such as knee injuries, that will be valuable for diagnostic purposes.Type: GrantFiled: August 9, 2012Date of Patent: December 20, 2016Assignee: The Regents of the University of CaliforniaInventors: Mark Sena, Brian Feeley, Dezba Coughlin, Jeff Lotz

Patent number: 9522256Abstract: In a coil-type guidewire, a coating portion of the coil portion is formed by stacking a plurality of films. An innermost film of the coating portion is arranged to come between adjacent coils of the coil body, and voids are formed between the innermost film and a film disposed outside of the innermost film. By forming such voids, it is possible to easily bend the coating portion and to improve flexibility of the coating portion. As a result, the guidewire in which the coil body is covered with the coating portion and the coil body (the guidewire) can be easily curved.Type: GrantFiled: June 25, 2014Date of Patent: December 20, 2016Assignee: ASAHI INTECC CO., LTD.Inventor: Keigo Takada

Patent number: 9402547Abstract: 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: August 2, 2016Assignee: MedicaMetrix, Inc.Inventor: Christopher LaFarge
