Publication number: 20240156368Abstract: The invention describes a method for continuous or intermittent wireless monitoring of the volume of cardiac chambers, with the ability to combine these with pressure measurements for optimal remote monitoring of cardiac patients. The invention comprises a set of wireless sensors such as resonators or reflectors placed within a cardiac chamber (i.e., the left ventricle), means for sensing the pressure within one or more cardiac chamber, and an external device adapted to interrogate the wireless sensors, determine their relative and/or absolute positions with respect to each other and/or the external device, and calculating the resulting volume of the cardiac chamber and creating pressure-volume loops.Type: ApplicationFiled: November 8, 2023Publication date: May 16, 2024Inventor: Reuven M. Lewinsky

Publication number: 20150057649Abstract: Disclosed are apparatus, method, devices and instruments, including an apparatus that includes a flexible waveguide coupled to a supporting structure, and further coupled to a treatment tip. The apparatus also includes a beam controller to control application of a radiation beam emitted from the flexible waveguide to distribute the beam over an area different than an area covered by direct application of the beam to a single location on a target tissue. Further disclosed is an apparatus that includes a waveguide, coupleable to a laser source, and a thermal protection instrument. The thermal protection instrument includes a tissue contacting member to contact a part of an area of a tissue irradiated by laser radiation, and a beam blocking element to absorb at least some of radiation not absorbed by the area of the tissue, the beam blocking element being thermally isolated from the area of the tissue.Type: ApplicationFiled: November 1, 2014Publication date: February 26, 2015Inventors: Reuven M. Lewinsky, Roee Khen

Publication number: 20140024894Abstract: Disclosed is an apparatus that includes a modifiable fiber structure adapted to operate in at least two configurations such that is a sideways-firing configuration the fiber structure is adapted to emit radiation in a substantially sideways direction relative to a longitudinal axis of the fiber structure, and in another, axial-firing, configuration the fiber structure is adapted to emit radiation in substantially axial direction relative to the longitudinal axis of the fiber structure. Also disposed is another apparatus that includes a guide tube disposed within a scope, the guide tube configured to be advanced to a position near an area to be treated so that the scope can be advanced along the guide tube to the position near the area to be treated. The guide tube is further configured to receive a treatment instrument to perform a treatment procedure on the area to be treated.Type: ApplicationFiled: July 12, 2013Publication date: January 23, 2014Inventors: Reuven M.
