Abstract: It is provided an invasive instrument for the treatment of a vessel, which possibly includes secondary vessels, with a tip formed for the dissection of tissue at the distal end of a shaft to be introduced into the body. The tip includes at least one recess, in particular a vessel receptacle, which is arranged and formed such that in the operating condition of the instrument always at least one functional unit of the shaft is kept clear, so that working on the vessel, a secondary vessel and/or on the surrounding tissue is possible using or by means of the functional unit.

Abstract: An invasive instrument for treating a vessel, which possibly includes secondary vessels, has a tip formed for the dissection of tissue at the distal end of a shaft to be introduced into the body, with at least one functional unit. The tip includes vessel receptacle means, arranged and formed such that, in the operating condition of the instrument, the functional unit of the shaft is kept clear, so that working on the vessel, a secondary vessel and/or on the surrounding tissue is possible using or by means of the functional unit and with the vessel receiving means the vessel can be fixed in a spatial position. The tip is movable relative to the shaft by means of a guide element and the tip is shiftable in axial direction, so that during the procedure a vessel arranged in the vessel receiving means can be spaced selectively from the functional unit.

Abstract: The present invention relates to a method for controlling the gas temperature in medical devices by means of a state observer, e.g., in the field of laparoscopy or respiration, and to devices for carrying-out said method.

Abstract: The present invention relates to a device and a method for determining mixing ratios of flowing media, in particular for determining the mixing ratios of two gases by using two flow resistances with different characteristic curves, each flow resistance containing a differential pressure sensor and being connected in series, where one flow resistance is formed by a sintered metal filter and another flow resistance is formed by an orifice.

Abstract: A connecting element for connecting two hollow bodies through which a fluid can flow comprises a first connecting part which can be brought into fluid-tight flow connection with a first hollow body through which a fluid can flow, a sealing element which is arranged at least partially in an inner area of the first connecting part and a locking element which is arranged on an outside of the first connecting part. The locking element can be transferred from an unlocked position into a locked position, wherein the locking element in the locked position acts upon the sealing element in such a way that an inside diameter of the sealing element is smaller than when the locking element is in the unlocked position.

Abstract: A device for multi-photon fluorescence microscopy for obtaining information from biological tissue has a laser unit for generating an excitation radiation, an optical unit implemented for focusing the excitation radiation for generating an optical signal at various locations in or on an object to be investigated, and a detector module for capturing the optical signal from the region of the object. The optical unit is thereby displaceable at least in one direction relative to the object for generating the optical signal at various locations in or on the object. The invention further relates to a method for multi-photon fluorescence microscopy. In said manner, a device and a method for multi-photon fluorescence microscopy are provided for obtaining information from biological tissue, allowing recording of section images in an object with a large field of view, and thereby are simply constructed and reliable in operation.

Abstract: The present invention relates to a tube with an integrated heating element for laparoscopy. By means of a humidifying material in the interior of the tube, the gas introduced during laparoscopy is heated and humidified.

Abstract: An imaging system for the fluorescence-optical visualization of a two-dimensional or three-dimensional object is provided. The imaging system comprising an illumination unit, which is designed and provided for emitting optical radiation in a predetermined wavelength range in order to illuminate the object and excite a fluorescent substance contained in the object, and a capturing unit, which is designed and provided for capturing an optical signal from the region of the object and for splitting the optical signal into a fluorescence signal having a first wavelength range and a signal of visible light having a second wavelength range. The optical capturing unit has an optoelectronic converter having a plurality of partial regions and serving for converting the fluorescence signal into a first electronic data signal and the signal of visible light into a second electronic data signal.

Abstract: An insufflation apparatus (2) to be connected through a hose (9) to a gas supply device (3), said hose (9) being connectable to the gas supply device (3) by a hose coupling interface including complementary connection elements (11, 12) at or in gas supply device (3) and at the hose end (9) directed towards the gas supply device, and a sterile filter element (10) being provided. The sterile filter element (10) carries connection element (12) of hose (9).

Abstract: A medical device with a medical apparatus (2) includes an accessory port, and with at least one accessory piece (1) having a connection element that is complementary to the accessory port. The connection element includes a storage unit where coded identification information is stored. With accessory piece (1) connected to device (2) coded or un-coded identification information is readable by a readout unit disposed in the section of the accessory port. In the case of reading coded identification information, de-codable, read-out and de-coded identification information is compared to identification information stored in readout unit. The medical device is activated when the identification information matches the desired identification information. The device is blocked when the identification information does not match. The coded identification information is de-coded by means of a proprietary key code.

Abstract: A hose cassette (1), for a peristaltic pump (2), includes a cassette housing (3) and a flexible hose (4) extending through cassette housing (3). The hose (4) is guided in the cassette housing (3) along a circular segment. The cassette housing (3) has a cutout (5) for the engagement of a roller wheel (6) of a peristaltic to pump (2) into the interior of said circular segment. The hose cassette has connection elements (7), (8) for connecting the cassette housing (3) to the peristaltic pump (2). At least one hose leg (9), (10) to be connected to the circular segment is displaceably held between a mounting position and an operating position in the cassette housing (3).
