In this case, the wire has two portions R1 and L1, which are adjacent to the two ends of the wire and are aligned parallel to one another and rectilinearly. Two second portions R2 and L2 follow on from these two first portions R1 and L1, these two portions R2 and L2 being connected to one another by a portion C. This portion C in turn has a flattened portion CC.Type: ApplicationFiled: January 2, 2024Publication date: July 11, 2024Applicant: OLYMPUS WINTER & IBE GMBHInventors: Christoph KNOPF, Christian BROCKMANN, Jiri LAVICKA, Petr KOMINEK

Publication number: 20240225722Abstract: This invention relates generally to apparatus and methods for tightening tissue of the female genitalia by heating targeted connective tissue with radiant energy, while cooling the mucosal epithelial surface over the target tissue to protect it from the heat. Embodiments include a treatment tip that comprises both an energy delivery element and a cooling mechanism. As the treatment tip contacts the epithelial mucosa, the tip cools the mucosa by contact, and delivers energy through the epithelium to the underlying tissue, thereby creating a reverse thermal gradient. The effect of the applied heat is to remodel genital tissue by tightening it. Such remodeling may include a tighter vagina and a tighter introitus. The tightening may be a consequence of thermal denaturation of collagen as well as a longer term healing response in the tissue that includes an increased deposition of collagen.Type: ApplicationFiled: February 2, 2024Publication date: July 11, 2024Inventor: Jonathan B.

Publication number: 20240225724Abstract: A system for applying a series of pulse field ablation (PFA) pulse trains to tissue of a heart includes energy-generating circuitry and a processor. The processor is configured to apply one of the pulse trains using the energy-generating circuitry and a catheter in the heart, to store a location of the catheter at which the one of the pulse trains is applied, to track a position of the catheter following the application of the one of the pulse trains, to detect, based on the tracking, that the catheter is within a predefined distance from the location following a predefined minimum duration from a most recent one of the pulse trains, and to apply another one of the pulse trains, in response to the detecting, using the energy-generating circuitry and the catheter. Other examples are also described.Type: ApplicationFiled: October 24, 2022Publication date: July 11, 2024Inventor: Assaf Govari

Publication number: 20240225726Abstract: A catheter configured to be used in a medical procedure includes a shaft and electrically conductive splines. The splines can include an insulated portion and a non-insulated portion configured to electrically ablate tissue. The catheter can include one or more electrodes coupled to insulated portion(s) of the splines and configured to sense electrical signals in the tissue. The splines can be coupled to an apex, forming an expandable distal-end assembly. The catheter can include a bump stop coupled to the apex and configured to maintain a minimal distance between the apex and the distal tip of the shaft. An ablation system can include the catheter, a generator, and a processor configured to control ablation energy from the generator to the splines such that ablation energy is applied to a first spline without applying ablation energy to a second spline.Type: ApplicationFiled: March 26, 2024Publication date: July 11, 2024Inventors: Assaf GOVARI, Christopher Thomas BEECKLER, Andres Claudio ALTMANN, Joseph Thomas KEYES, Kevin Justin HERRERA

Publication number: 20240225729Abstract: A compact laser-steering end effector includes a frame, at least two active mirrors, and a pair of actuators. The frame has a greatest dimension in a plane orthogonal to a longitudinal axis of no more than 13 mm, and the mirrors are mounted proximate to the distal end of the frame. The actuators are mounted to the frame and configured to respectively change the tilt of the active mirrors relative to the frame. A pathway is provided through the frame to deliver a laser beam to the mirrors, and wherein the mirrors are positioned and configurable via the actuators to reflect the laser beam off of each mirror en route to an external target.Type: ApplicationFiled: October 28, 2020Publication date: July 11, 2024Applicant: President and Fellows of Harvard CollegeInventors: Peter A.
