Abstract: A surgical manipulator includes an intracorporeal unit that is completely arrangeable within a body cavity and that includes a coupling member and an effector. An extracorporeal unit includes a manipulator to manipulate at least the effector, and a connecting unit for connecting the intracorporeal unit to the extracorporeal unit when the intracorporeal unit is arranged within the body cavity and for transferring manipulating activities from the extracorporeal unit to the intracorporeal unit.

Abstract: The present invention discloses a magnet driven capsule type endoscope comprising an image recording unit as well as an image data processing unit, a position sensor for providing data about the position of the capsule type endoscope with respect to the direction of gravitation, a data transmitting unit, an energy source for supplying the units and the sensor with energy and a permanent magnet. In accordance with the invention, the permanent magnet is arranged offset with respect to the center of gravity and to the geometrical center of the capsule type endoscope.

Abstract: The invention is directed to an endoscopic retrieval instrument for receiving and retrieving one or more objects from the human body, the instrument comprising an insertion instrument, a retrieval container, and a coupling mechanism configured to selectively disconnect the retrieval container from the insertion instrument.

Abstract: The medical implant for treating pathological obesity is adapted to modify and, as an alternative, to bypass the natural food passage in the digestive tract. The implant permits an adjustable bypassing of food into the small intestine and/or into the stomach (natural digestive path). Since the ratio of this bypass is adjustable in the course of the treatment by the physician, e.g. with the aid of an endoscope, for the first time a balance between the therapeutic effect and the side-effects can be adapted individually to each patient by the use of the implant. The implant has a hollow body with first and a second tubular end portions and at least one third lateral opening having a hose-like extension. The individual at least partly closable hose-like extensions differ in their ability to allow the passage of food into the stomach.

Abstract: The present invention relates to a medical device for changing the shape of hollow organs in the human body, comprising at least one issue clamp, clip or anchor, which can be fixed to the organ tissue by means of a clamping or hooking-in action in order to provide a fixation point or a point of transmission of force in the organ. The clip or anchor has a receiving-element portion or hooking-in device for a flexible band, wire or tube, by means of which a force causing the change in shape can be applied to the organ at least partially via the clip.

Abstract: A device for hemorrhage detection comprising a detector for detecting the presence of blood, the detector being connected to a fixing, apparatus. The fixing apparatus is fixed to the inner wall of a hollow organ. The device further has a transmitting unit by which data transmitted by the detector are adapted to be transmitted to a receiving unit disposed outside the body.

Abstract: The ability of a person to grasp an object and at the same time to feel, as well as to determine mechanical and geometric parameters of the comprehended object, makes him or her irreplaceable for many tasks, i.e. in production or in surgery. The translation of this ability into a technological system has often failed up to now due to lack of special adjusted sensors. The object of this invention is a sensory device, which fulfills the requirements for a tactile sensor system and at the same time affords a cost-effective and simple manufacturing alternative to other sensor principles. The layer structure of the sensor element is so constructed that by effect of an external force of the current by a resistive layer a path is disposed to narrowing or enlargement. The voltage drop over this resistive layer is dependent upon the acting external force and serves as signal sensor.

Abstract: A device for hemorrhage detection comprising a detecting means for detecting the presence of blood, said detecting means being connected to a fixing means. The fixing means is fixed to the inner wall of a hollow organ. The device further has a transmitting unit by which the data transmitted by the detecting means are adapted to be transmitted to a receiving unit disposed outside the body.

Abstract: A rigid endoscope includes a jacket tube with an optical system and, parallel to the optical axis of the optical system, a first glass fiber bundle which emits a beam to illuminate an object to be examined. A second optical illumination system is directed at the object being examined. The second light exit of the second optical illumination system is recessed from the first light exit of the optical system by a distance greater than a diameter of the jacket tube. The light exit axis at the second light exit of the second optical illumination system is offset laterally relative to the image axis at the distal end of the optical system by an amount such that because of the resultant parallax and the shadow formation and unequal light distribution thus attained, the vividness of the image impression for three dimensional objects is increased.
