摘要： A device for manipulating a stylet unit for positioning an electrode cable in a body cavity has an elongate housing, an elongate, axial cavity in the housing and an operating slide, axially movable in relation to the housing, for attachment to a proximal end section of a tubular stylet sleeve in a stylet unit. An elongate coil spring is located in the cavity on the proximal side of the manipulation device. The coil spring forms an inner guide channel to prevent the buckling of the free, proximal end section of the stylet of the stylet unit in the cavity.

摘要： A stylet unit which can be introduced into a narrow, hollow, flexible component, such as a hollow electrode cable for a heart stimulator, to stiffen the component and bend its distal end section, is in the form of a double stylet combination with a flexible stylet shell and an internal stylet, movably arranged inside the shell, with a pre-curved distal end section, whose radius of curvature is on a first side of the stylet. In an area before the pre-curved end section, the stylet has a pre-shaped stylet section with a pre-shaped stylet section whose radius of curvature is on the side of the stylet opposite the first side on which the end section's radius of curvature lies.

摘要： A stylet unit suitable for stiffening a hollow electrode cable, such as during the introduction and the anchoring of a medical electrode cable in the human body, includes a combination of a pair of flexible, coaxially arranged stylet elements, i.e., a tubular stylet sleeve and an internal stylet, which can be inserted into a channel in the sleeve and whose end section is pre-bent to one side. Both the stylet sleeve channel and moving inner stylet contained therein have sections or segments with non-circular cross-sections, the profile of the stylet's non-circular cross-section, in relation to the profile of the sleeve channel's non-circular cross-section, preventing the stylet from rotating in relation to the surrounding sleeve, at least within the parts of the sleeve in which both the stylet and the sleeve channel have interacting non-circular cross-sections. The stylet sleeve also has a distal end section which is pre-bent in a first lateral direction in relation to the stylet unit, and the inner stylet's distal end section is pre-bent in the diametrically opposite lateral direction. The rotation-preventing non-circular cross-sections ensure that the oppositely pre-bent stylet and sleeve portions remain in the same plane, so the forces respectively produced by each substantially cancel, thereby facilitating relative movement of the stylet in the sleeve.

摘要： A stylet unit, which can be introduced into a hollow, flexible component, such as an electrode cable, to stiffen the component and to bend a distal end section is formed by a double stylet combination of a flexible tubular stylet shell and an internal stylet, movably arranged inside the shell's channel, with a pre-curved distal end section. This end section can be set at a retracted internal position inside the stylet shell or at an exposed position outside the shell. The internal stylet's pre-curved distal end section is made of a memory metal and has a radius of curvature which varies longitudinally along the end section. The end section can be in the shape of a spiral, and the memory metal can be made of a nickel-titanium alloy.
