Abstract: An implant with which prostates of different sizes can be treated is achieved by the fact that the length of a deployed implant is modifiable to a variable extent. Through the change of length of a stretched-out wire structure of the implant, the implant can be adapted individually to the patient anatomy and the outcome of treatment can thus be improved.

Abstract: A surgical handheld devices are essentially made up of a device body or main body and of a tubular shaft. In the production of known surgical devices, the tubular shafts are welded to the device bodies. A large number of very complex work steps are necessary for this purpose. On account of the high quality demands placed on surgical handheld devices in respect of mechanical stability and sterility, the weld seam has to meet the most stringent requirements. The invention makes available a method for producing a surgical handheld device, which can be used particularly easily and reliably. This is achieved by the fact that at least one device body and at least one tubular shaft of a surgical handheld device are connected to each other with form-fit engagement by hydroforming.

Cleaning them is very laborious, particularly when they have bores and receptacles of small diameters. Even mechanical cleaning cannot guarantee that the necessary degree of cleaning is achieved. The invention makes available an electrosurgical handheld device and a contact body that can be cleaned particularly easily and thoroughly and in a time-efficient manner. This is achieved by the fact that the contact body for an electrosurgical handheld device has at least one receptacle that is designed as a continuous bore through the contact body.

Abstract: In known electrosurgical handheld devices, a strengthening tube is firmly connected to a working element or a main body. Before the strengthening tube is connected to the main body, a contact body has to be pushed over the strengthening tube. For this purpose, the contact body has a corresponding bore. When the contact body is replaced for maintenance reasons or because of defects, the strengthening tube has to be removed with difficulty from the main body in order to be able to withdraw the contact body from same. The invention makes available an electrosurgical handheld device and a contact body which is able to be manipulated and maintained in a particularly simple and also time-efficient manner. This is achieved by the fact that a contact body for an electrosurgical handheld device has a slit parallel to a continuous bore and also parallel to a longitudinal axis of the handheld device.

Abstract: A surgical radiofrequency instruments such as resectoscopes, for example, are used for removing or manipulating body tissue. A particular disadvantage of known instruments has been that the arrangement of an electrode instrument in an inner shaft can influence a flow behavior of an irrigation liquid.

This is achieved by the fact that an electrode instrument has two electrode carriers which are arranged parallel to each other and are connected to each other by at least one guide element, and this at least one guide element extends, at least in part, convexly away from a longitudinal axis.

Abstract: Radiofrequency instruments such as the resectoscope described here are used in medicine for treating body tissue and in particular for removing or manipulating this tissue.

Abstract: High-frequency (HF) tools are used in medicine for manipulating body tissue, using an HF resectoscope. For electrical insulation of an electrode from an electrode support, the ends of the electrode are initially guided through ceramic tubes. These ceramic tubes are sensitive in particular to forces transverse to the longitudinal axis of the resectoscope. Disclosed herein is a high-frequency tool that has increased stability with respect to transverse forces. An electrode has two ends, which for establishing a connection to an electrode support are each insertable into a receiving opening of the ends of the electrode support, or positionable in front of the ends. The electrode is contacted in an electrically conductive manner, at least in the area of a receiving opening, with a conductor wire that is guided in the electrode support.
