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 invention concerns a hose cartridge for a peristaltic pump comprising a cartridge housing, comprising a flexible pump hose segment extending through the cartridge housing, wherein both ends of the pump hose segment are fixed in the cartridge housing by a first fixing member and a second fixing member, wherein the first fixing member and the second fixing member are arranged in the area of a first front face of the cartridge housing, and wherein the cartridge housing includes a recess for the engagement of a roller wheel of the pump in the interior of the cartridge housing. It is characterized by that the pump hose segment extends in the hose cartridge along a circular segment (K) spanning an angle of at least 90°, when the hose cartridge is not inserted into the pump.

Abstract: The invention concerns a peristaltic hose pump comprising a roller wheel (1) rotatable about a roller wheel axis (D), which roller wheel has rollers that are mounted thereon (2), the roller wheel rotation axes (R) of which are arranged on a circle concentric with the roller wheel axis (D), the rollers (2) partly projecting beyond the roller wheel (1), comprising a hose (3), which has a flexible and elastic pump segment (4), and the pump segment (4) being fixable in the axial direction at its two opposite ends (5, 6) by means of one fixing point (P1, P2) each, and the pump segment (4) being guided around the roller wheel (1) under elastic tension, wherein the length (L1) of the pump segment (4) when not under tension in proportion to the distance (A) of the fixing points (P1, P2) to the roller wheel rotation axis (D) is adjusted with the provision that while the roller wheel (1) is stationary and when applying a fluid pressure in the range from 10 to 400 mbar to one end (P1, P2) of the pump segment (4), a flow

Abstract: A method for visual characterization of human or animal tissue formed from cells, having the following steps: a radiation source for emitting directional electromagnetic radiation is provided; —the tissue to be irradiated with the radiation, this producing a reflection in the tissue which is characteristic of the tissue, with—the radiation which has penetrated the tissue having, within an excitation region extending transversely with respect to the direction of propagation of the radiation, a sufficient intensity to excite a reflection in the tissue. The radiation emitted by the radiation source is impressed with an intensity profile, transversely with respect to its direction of propagation, which is such that the excitation region covers a plurality of cells of the tissue and the excited reflection originates from inter-cell tissue properties.

Abstract: A device for rinsing a body cavity with a fluid includes a rinse pump for introducing fluid into a body cavity and a pressure sensor on a pressure side of the rinse pump. A medical instrument insertable into the body cavity is adapted to establish fluid communication with the body cavity. A suction pump is in fluid communication along a first pathway with the medical instrument and along a second pathway with the body cavity. Fluid flow along the second pathway is controllable. A control unit receives pressure values from the pressure sensor, controls the rinse pump, the suction pump, and the flow controller in response to received pressure values, and is thus operative to control fluid flow through the body cavity depending on an operating condition of the medical instrument.

Abstract: A peristaltic hose pump comprising a roller wheel, which can rotate about a roller wheel axis and which has rollers that are mounted on the roller wheel. The rollers roll along a circular path having a certain radius with respect to the roller wheel axis. The peristaltic hose pump also comprises a pressure arched element with a supporting surface, whereby the supporting surface extends along a circular path having a certain radius around the rotation axis of the roller wheel. In addition, a flexible hose can be inserted between the supporting surface and the rollers of the roller wheel.
