摘要:
The invention relates to a connecting piece for connecting to an electrode line and to an electric implant, whereby the connecting piece has an electrically conducting plug module, multiple ring-shaped electrically conducting contacts with insulation sections having the same outside diameter arranged in the longitudinal direction therebetween, multiple electric connecting lines, and a supporting element which supports the insulation sections and secures them in the radial direction. A through-bore situated within the supporting element receives the plug module and/or a feeder line of an electrode body. The supporting element has grooves spaced along the longitudinal direction, and recesses extending from the proximal end to the distal end and running parallel to the longitudinal axis wherein the electric connecting lines are fit.
摘要:
A terminal part for an electrode line for connection to an implantable heart stimulator, the terminal part having multiple annular, electrically conductive contacts of equal external diameter having insulation sections of the same external diameter situated between them in the longitudinal direction, of which the electrically conductive contacts are each electrically connected to an electrically conductive terminal line, the terminal part being formed by multiple insulating adapters and by electrical contacts held thereby having terminal lines fastened thereon, which are plugged together and connected using a thermoplastic injection molding compound after being plugged together, the terminal part otherwise being implemented in such a way that it is to be connected as an independent unit to a remaining electrode line.
