Abstract: A medical device (10) for use in passageways of the human or animal body comprises a catheter (30) having an expandable arrangement (38), such as a balloon arrangement, located at the distal portion of the catheter, and capable of deploying a stent apparatus (20) mounted at the distal portion of the catheter (30). The stent apparatus (20) is a hybrid stent apparatus having a central part (21) that is self-expanding, and end parts (22, 23) that are expandable by the balloon arrangement.

Abstract: The electrode comprises a plate-shaped part (2) having a portion for establishing contact with the skin of a patient, and a flange part (5) connected with the plate-shaped part. Snap connecting means (6) are provided on the flange part and includes a stud portion (7) for establishing connection to a lead wire connector means of a measuring apparatus and a base portion (8) formed integrally with the stud portion. A conductive area (4) extends between the skin contact establishing portion and the snap connecting means (6). Fastening means for fastening the snap connecting means to the electrode is formed integrally with the base portion and comprises a plurality of legs (9) which protrude from the base portion. The legs are folded to a position in which they abut against the conductive area (4).
