Abstract: An ultrasonic control apparatus has a connector and a connector cover. The connector cover is attached to be slidable between a close position where the connector is covered and an open position where the connector is exposed, and has a press projection. When the connector is set on the press projection and then pressed down together with the connector cover, the connector is exposed and opposed to the connector, and the connectors can be connected with each other.

Abstract: A fluid delivery system for use with an endoscope. Certain embodiments of the invention include a single, large fluid source and pump installed upon an operator console, in combination with a small fluid reservoir and pump installed within a proximal connector of the imaging endoscope, multiple fluid sources that feed a common fluid channel that are pressurized by a common pump, multiple fluid sources that feed dedicated fluid channels that are pressurized by dedicated pumps, and a small fluid reservoir and pump installed within a handheld manual controller of the imaging endoscope. The fluid delivery endoscopic systems of the present invention provide the user with the flexibility of changing fluids either in advance of a procedure or on-the-fly as needed, instead of relying on fixed fluid sources only.

Abstract: The present invention provides an endoscope comprising: an insertion unit which is to be inserted into a body; and a pipeline provided inside the insertion unit for supplying a fluid to a balloon mounted on an outer peripheral surface of the insertion unit, wherein the pipeline has a plurality of openings in an axial direction of the insertion unit on the outer peripheral surface of the insertion unit. Therefore, the endoscope of the present invention can easily fix a balloon and keep airtightness after the fixation, and can raise a degree of freedom of a mounting location of the balloon.

Abstract: Described is a tissue resection system which includes a guide element; a resection head; a positioning mechanism and an actuating mechanism. The resection head includes a guide channel slidably receiving the guide element and an endoscope channel sized to slidably receive an endoscope therein, so that, when the resection head is slid along the guide element, the endoscope and the resection head follow a path defined by the guide element. The positioning mechanism moves the resection head relative to a distal end of the endoscope between a first position in which the distal end of the endoscope extends distally out of the endoscope channel and a second position in which the distal end of the endoscope is received within the endoscope channel. The actuating mechanism moving a portion of an outer wall of the resection head to open and close a resection chamber defined by the outer wall.

Abstract: The invention relates to an endoscope having a bendable guide element, by means of which a tool can be securely guided and simultaneously steered outward into a broad operating area at the head of the endoscope.

Abstract: The invention relates to a method as well as to a system for the local heating of a target region of an object by varying the magnetization of magnetic or magnetizable substances. A magnetic field is then generated whose magnetic field strength varies in space in such a manner that a first sub-region (301) of low magnetic field strength and a second sub-region (302) which encloses the first sub-region and has a higher magnetic field strength are formed in the target region. Subsequently, the position in space of the two sub-regions in the target region is varied with a given frequency for so long that the particles are heated to a desired temperature due to frequent variation of the magnetization.

Abstract: A first medical instrument includes a medical catheter, a rotatable member, an injection needle, and at least one medical-treatment electrode supported by the rotatable member. The medical catheter has a distal end. The rotatable member is connected to the medical catheter and is rotatable with respect to the medical catheter. The injection needle is movable to extend from, and to retract within, the distal end of the medical catheter. A second endoscope adjunct includes a medical catheter, a rotatable member, and at least one medical-treatment electrode supported by the rotatable member. The medical catheter has a distal end and has a lumen adapted to receive the injection needle. The rotatable member is connected to the medical catheter is rotatable with respect to the medical catheter.

Abstract: An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member and integrally associated with the knife. The monopolar element is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member.

Abstract: A device for positioning at least one optical component inside an endoscopic system has a housing through which an optical axis of the endoscopic system extends and in which the at least one optical component is arranged. The at least one optical component can be pivoted into the beam path and back out of the beam path about a pivot axis extending substantially parallel to a longitudinal axis of the housing, the at least one optical component being arranged on a support which is pivotable about the pivot axis. A smallest distance of an inside wall of the housing from the pivot axis is smaller than a greatest distance of the pivot axis to an outer edge of the at least one optical component.
