Abstract: A safety device for shielding a medical needle, includes a hand grip element; a cannula held at the hand grip element; a base with laterally protruding, flat wings, the base having a guide opening which is spaced apart from the underside and in which the cannula is guided; and a connecting structure which connects the handle element with the base and includes two elongated sections connected in a row with one another by at least one joint and the connecting structure is connected at one end by at least one joint with the hand grip element and, at the other end, by at least one joint with the base, the elongated section of the connecting structure, which is connected with the base has a wall element which protrudes transversely at its base end, and the connecting structure can be unfolded from a first state into a second extended state.

Abstract: A device for administering a cannula (14), having a basic element (10),the cannula (14), a tip (16) of which protrudes beyond the basic element (10) in a ready to use position of the device, a traction element (12), which is movable with respect to the basic element (10), and a releasable pretensioning device (36, 38, 40) for pretensioning the traction element (12) with respect to the basic element (10) in the ready to use position of the device, wherein the traction element (12) interacts with the cannula (14) so that, when the pretensioning device (36, 38, 40) of the traction element (12) is released, the tip (16) of the cannula (14) retracts into the basic element (10).

Abstract: A flexible catheter includes two electrical contacts in a distal region of the catheter and a distal aperture of a hose line. The electrical contacts are connected to a high frequency pulse generator for applying pulsed radio frequency energy for nerve stimulation. A temperature sensor is located in the distal region of the catheter. The flexible catheter is inserted into a region in the spinal canal and the pulsed radio frequency generator is operated, thereby applying pulsed radio frequency energy to a localized region to be treated. The temperature at the distal region of the catheter can also be monitored, and the pulsed radio frequency energy is applied in dependence on the monitored temperature. With the catheter, pain and other medical conditions being related to and influenced by a nervous system are treated.
