Patent number: 9717432Abstract: Physiological monitoring can be provided through a wearable monitor that includes a flexible extended wear electrode patch and a removable reusable monitor recorder. A pair of flexile wires is interlaced or sewn into a flexible backing, serving as electrode signal pickup and electrode circuit traces. The wearable monitor sits centrally on the patient's chest along the sternum, which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. The electrode patch is shaped to fit comfortably and conformal to the contours of the chest approximately centered on the sternal midline. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive is provided on the underside, or contact, surface of the electrode patch, but only on the distal and proximal ends. Interlacing the flexile wires into the flexile backing also provides structural support and malleability against compressional, tensile and torsional forces.Type: GrantFiled: August 19, 2014Date of Patent: August 1, 2017Assignee: Bardy Diagnostics, Inc.Inventors: Jason Felix, Jon Mikalson Bishay, Gust H.

Patent number: 8948838Abstract: The present invention provides impedance data having an improved spatial resolution, both with regard to depth and lateral extension, which enables a detection of diseased skin conditions, such a malignant melanoma, at an early stage. Specifically, the present invention is implemented in a probe, medical devices and medical systems including such a probe, and methods using such a probe for measuring electrical impedance of tissue of a subject. A switching circuit is arranged for selectively activate electrode pairs of the probe in accordance with a predetermined activation scheme, the predetermined activation scheme including to activate adjacent electrodes in a successive manner, to gradually scan tissue of the subject at a first tissue depth so as to obtain a sequence of impedance signals from the tissue depth.Type: GrantFiled: January 27, 2009Date of Patent: February 3, 2015Assignee: Scibase ABInventors: Fredrik Goldkuhl, Marcus Gunnarsson, Ulrik Birgersson

Patent number: 8939153Abstract: A transponder string comprising multiple transponders is configured for injection into human tissue. In one embodiment, the transponders are sized to move through a needle for injection into the human tissue. Positions of the transponders with reference to one another may be maintained by coupling the transponders via a filament, adhesive backed substrate, shrink tubing, and/or any other suitable substrate. The transponders are configured to transmit data to a mobile computing device, e.g., a wand, smart phone or wireless tablet positioned outside the human tissue such that positions of the transponders are determinable, e.g., during an excision surgery.Type: GrantFiled: March 13, 2014Date of Patent: January 27, 2015Assignee: Health Beacons, Inc.Inventors: Murray A. Reicher, Robert Petcavich
