Catheter and catheter arrangement
The catheter (10) has an elongated catheter body (13) comprising a distal end (10d) and a proximal end, where the catheter is designed as an electrode line. A sponge or cushion-like elastic deformation body is arranged at the distal end, and has an electrically, mechanically or optically-acting measuring unit or measuring connection to detect pressing force exerted on the body. The body contains plastic foam with electrically-conductive polymer or with particles made of ferroelectric film, or fluid e.g. liquid, gel or filling of pourable particles. The catheter is provided with a stimulation and/or sensing electrode that is made of conductive plastic.
