Publication number: 20160345845Abstract: The present disclosure is directed to apparatuses, systems and methods for measuring time-varying radar cross section (RCS) of an artery of a patient, which may be used to determine blood pressure of a patient. In some embodiments, an apparatus is provided which comprises a radio-frequency (RF) transceiver for generating RF waves, and at least one sensor configured for positioning on or adjacent the skin of a patient, and at least one of transmitting the RF waves into tissue of the patient and receiving RF wave reflections from at least one artery located within the tissue. The apparatus may further comprise a processor having computer instructions operating thereon configured to cause the processor to determine an RF arterial pulse waveform based on the received RF wave reflections. The time-varying radar cross section (RCS) comprises the RF arterial pulse waveform. This may be in turn correlated to blood pressure of the patient.Type: ApplicationFiled: February 5, 2015Publication date: December 1, 2016Applicant: KYMA MEDICAL TECHNOLOGIES LTD.Inventors: Rafi RAVID, Uriel WEINSTEIN

Publication number: 20160213321Abstract: A method and apparatus are provided for determining and tracking location of a metallic object in a living body, and then directing a second modality such as ultrasound waves to the determined location. The metal detector may be a radar detector adapted to operate on a living body. The adaption may include disposing a transfer material having electromagnetic properties similar to the body between the radar detector and the living body, ECG gating the radar detector, and/or employing an optimal estimator with a model of expected stent movement in a living body. Applications include determination of extent of in-stent restenosis, performing therapeutic thrombolysis, or determining operational features of a metallic implant.Type: ApplicationFiled: April 7, 2016Publication date: July 28, 2016Applicant: Kyma Medical Technologies Ltd.Inventors: Assaf BERNSTEIN, Uriel WEINSTEIN, Vered COHEN SHARVIT, Dov OPPENHEIM

Patent number: 9220420Abstract: Diagnostic apparatus (24) includes a sealed case (80), comprising a biocompatible material and configured for implantation within a body of a human subject (22). A dielectrometric probe (26, 50, 63, 66, 70, 102, 160) is connected to the case and includes first and second conductors (40, 42, 54, 56, 64, 67, 68, 72, 74, 162, 164), which are configured to be placed in proximity to a target tissue (34) in the body. A driving circuit (82), which is contained in the case, is coupled to apply a radio-frequency (RF) signal to the probe and to sense the signal returned from the probe. Processing circuitry (84) is configured to evaluate, responsively to the returned signal, a dielectric property of the target tissue.Type: GrantFiled: July 21, 2011Date of Patent: December 29, 2015Assignee: Kyma Medical Technologies Ltd.Inventors: Uriel Weinstein, Assaf Bernstein, Eyal Cohen, Dov Oppenheim, Moshe Mosesko

Patent number: 8989837Abstract: Embodiments of the subject application include a diagnostic apparatus including one or more antennas disposed on a thorax of a living body to direct radio frequency (RF) electromagnetic waves through tissue and output signals responsively to the waves that have passed through the tissue. The apparatus may also include processing circuitry configured to process the signals over time so as to measure one or more RF path characteristics of the RF electromagnetic waves. The RF path length may be defined by a length of time required for the RF waves to pass through the thorax to an antenna and/or pass to tissue and reflect therefrom to an antenna, based on the path characteristic to assess a fluid content of the tissue.Type: GrantFiled: April 14, 2010Date of Patent: March 24, 2015Assignee: Kyma Medical Technologies Ltd.Inventors: Uriel Weinstein, Assaf Bernstein, Eyal Cohen
