Publication number: 20240008915Abstract: Cardiac annuloplasty methods and devices, based on delivery of tissue-ablating energy to a heart valve annulus, thereby inducing reduction of the valve annulus perimeter. In some embodiments, the reduction is induced by shrinkage of tissue in response to ablation, potentially analogous to tissue shrinkage responsible for pulmonary vein stenosis induced by cardiac ablation to treat atrial fibrillation. In some embodiments, annulus tissue is deformed before ablation energy is applied. This potentially results in plastic deformation apart from tissue shrinkage. Deformation is optionally performed using electrodes that also operate as sharp-tipped jaws of a pliers. They are inserted to tissue in a wider-spaced configuration, reduced in distance to a narrower-spaced tissue-squeezing configuration, and operated to ablate the squeezed tissue. Upon removal of the electrodes, the squeezed tissue retains a new shape as a result of ablation-induced plastic deformation.Type: ApplicationFiled: May 4, 2021Publication date: January 11, 2024Applicant: Bio ReFine Ltd.Inventors: Dvir KEREN, Boaz SHENHAV

Publication number: 20240008921Abstract: Light-emitting depilation device includes light source, skin cooling unit that cools skin, and push switch including pressing unit that surrounds an outer periphery of light source and skin cooling unit. When pressing unit is not pressed, pressing unit is protruding from a surface of skin cooling unit, the surface being a surface that is to be brought into contact with the skin, toward an opposite side of light source with respect to skin cooling unit. Upon being pressed, a surface of pressing unit pressed by the skin moves closer to light source with respect to skin cooling unit. Push switch switches to cause light source to emit and not to emit light in such a manner that light is emitted from light source at least for a part of the time while pressing unit is pressed, and light is not emitted from light source while pressing unit is not pressed.Type: ApplicationFiled: December 24, 2021Publication date: January 11, 2024Inventors: Ryohei SAKAMOTO, Hideki KASUGAI

Publication number: 20240008923Abstract: Disclosed is a system provided with a vibration device and cooling fluid for interstitial laser therapy. Use of the vibration device to vibrate at least part of the system releases and assists in the transfer of gas bubbles (e.g. steam) produced during treatment use, thus stabilising the temperature at or near a treatment site. The system for interstitial laser therapy includes an optical waveguide having an optical output end and an associated optical diffuser, an irrigation tube, an outer tube (e.g. cannula) and a vibration device. The irrigation tube directs cooling fluid to flow out of a distal end of the irrigation tube which directs cooling fluid to flow inside of and/or outside of the optical diffuser. The vibration device is used to vibrate the irrigation tube, the optical diffuser and/or the outer tube.Type: ApplicationFiled: September 26, 2023Publication date: January 11, 2024Inventor: Celalettin VAROL

Publication number: 20240008925Abstract: Apparatus, systems, and methods for developing patient-specific surgical plans are disclosed. One illustrative computer-implemented method comprises identifying anatomical parameters of a knee joint, determining a subset of implant alignment options for a knee prosthesis when implanted from among a larger set of implant alignment options, where the subset consists of each implant alignment from the larger set that satisfies one or more flexion-extension gap criteria, determining a target ligament elongation of at least one ligament of the knee joint over a range of flexion based on pre-implantation anatomy, determining, for each implant alignment of the subset, a predicted ligament elongation of the at least one ligament over the range of flexion, identifying at least one recommended implant alignment of the knee prosthesis based on the target ligament elongation and the predicted ligament elongations, and incorporating the at least one recommended implant alignment into a patient-specific surgical plan.Type: ApplicationFiled: June 30, 2023Publication date: January 11, 2024Inventors: Matthew R. Dressler, Paul J. Rullkoetter, Chadd Clary, Clare K. Fitzpatrick
