Apparatus for implanting surgical electrodes or catheters into human hearts or other hollow body organs has one or more flexible guide wires defining one or more tracks for a streamlined carriage the rear end of which is formed with a cavity for reception of the leading end of a catheter or electrode. The carriage can be pushed along the guide wire or wires by the electrode or catheter, and the leading end of thus implanted object is thereupon extracted from or expelled laterally from or beyond the cavity in the carriage while the carriage is held against forward and/or rearward movement with reference to the guide wire or wires. The carriage can be extracted from the body by the guide wire or wires or by means of a cord or hose. The carriage serves as a shield in front of the leading end of an electrode or catheter during introduction of the latter by way of an artery, a vein or another body cavity.
