Abstract: A catheter comprising an elongated catheter body which has a distal end and a proximal end in respect of an operating position, wherein the catheter body comprises an inner tube and an outer tube which is displaceable relative thereto, and a deformation body is disposed on the distal end which is connected in the distal region thereof to the distal end of the inner tube, and in the proximal region thereof to the distal end of the outer tube.

Abstract: A catheter with an elongated catheter body which, with regard to a position of use, has a distal and a proximal end, wherein at the distal end, a sponge- or cushion-like elastic deformation body is arranged which has, in particular, electrically, mechanically or optically acting measuring means or a measuring connection for detecting a pressing force exerted on the deformation body.

Abstract: A catheter comprising a steering cable anchor, which is preferably disposed at the distal end of the catheter, and a steering cable. In order to obtain a reliable connection between the steering cable anchor and the steering cable, which is also suitable for use in MRI, a substantially dumbbell-shaped element is disposed between the steering cable anchor and the steering cable and connects the steering cable anchor to the steering cable.

Abstract: An irrigation catheter device, in particular an ablation catheter, including a catheter body in which a central lumen extends from a proximal region into a distal region, wherein a large number of irrigation channels extend away from the lumen, the outlet openings of which out of the catheter body are distributed across the distal end region thereof, wherein sensors are assigned to the central lumen and/or the individual irrigation channels for pressure measurement and/or to measure the flow velocity, to which evaluation means are connected, which are designed to determine the open or closed state of a portion of the irrigation channels on the basis of measured values registered by the sensors.

Abstract: An explantation device for explanting implanted leads, having a distal end pointing in the direction of the explantation site and a proximal end pointing in the direction of the surgeon. The explantation tool comprising a locking sheath comprising a hose-like or tubular body having a lumen along a longitudinal axis and at least one clamping device at or in the vicinity of the distal end; and a cutting sheath for removing adhering tissue, having a proximal and a distal end and comprising a hose-like or tubular body having a lumen along a longitudinal axis and a detaching unit at or in the vicinity of the distal end; wherein the cutting sheath comprises at least one receptacle for the clamping device of the locking sheath.

Abstract: A catheter comprising an elongated and axially rigid catheter body which has a distal end and a proximal end in respect of an operating position, wherein a movable and/or deformable protection element or a corresponding protection section of the catheter body, which is provided with predetermined motion or deformation resistance, is disposed on the distal end, and transducer means of a converter device for converting displacement into a non-mechanical quantity are provided in a stationary manner on the protection element or protection section, and corresponding pick-up means of the converter device are provided on the catheter body, or vice versa, and wherein the catheter body comprises a lead for transmitting a measurement signal generated by the converter device to the proximal end, and a measuring connector on the proximal end.
