Publication number: 20230181302Abstract: An implant in which the Lobus medius (median lobe) can be treated in a simple and reliable manner. This is achieved by virtue of the fact that an implant for the treatment of a urinary tract has a wire structure. The wire structure has a loop wire, which can be expanded to form a loop, wherein at least two net wires can be stretched in this loop and the wire structure can be placed around the median lobe.Type: ApplicationFiled: December 7, 2022Publication date: June 15, 2023Applicant: OLYMPUS WINTER & IBE GMBHInventors: Thorsten JÜRGENS, Thomas WOSNITZA, Henning SCHWEINBERGER

Publication number: 20230181304Abstract: An implant with which a urinary tract can be treated in a simple and reliable manner is achieved in that a wire structure of an implant can be introduced into the urethra in a folded state with a distal end in the lead. The wire structure is unfolded inside the urethra for the treatment of the tissue. The ischemic pressure of the wires on the surrounding tissue results in denaturation. At least one further device for constricting or cutting into tissue is positioned on the wire structure. This at least one further device is designed in such a way that it exerts a local ischemic pressure on the median lobe in the unfolded state of the implant.Type: ApplicationFiled: December 9, 2022Publication date: June 15, 2023Applicant: OLYMPUS WINTER & IBE GMBHInventors: Thorsten JÜRGENS, Thomas WOSNITZA, Henning SCHWEINBERGER

Publication number: 20220008117Abstract: A radiofrequency electrode for handheld devices are used predominantly in urology for electrosurgical work in the bladder, the prostate, and the urethra. A large active area of the electrode is known to be advantageous. However, the size of the area is restricted by the available space. Moreover, greater energy is required for igniting the plasma for large electrodes. However, an elevated energy level is disadvantageous in terms of the heat influx into the rinsing liquid and this may be disadvantageous for the surrounding tissue. The invention develops a radiofrequency electrode, an electrode instrument and a resectoscope, in which a plasma can be better localized at the electrode and the energy for igniting the plasma is reduced at the same time. This is achieved by virtue of a radiofrequency electrode for use in a surgical handheld device having the shape of a toroid.Type: ApplicationFiled: July 7, 2021Publication date: January 13, 2022Applicant: OLYMPUS WINTER & IBE GMBHInventors: Alexander CARROUX, Thomas WOSNITZA
