Patent ID: 7860576

Claim:
An intravenous pacemaker electrode with an electrode cable, comprising: a line; a catheter duct; an insulating sleeve covering the catheter duct and the line; an electrode head attached to a distal end of the line adapted to transmit stimulation pulses; an ultrasound catheter that is moved in the catheter duct and comprising a thread-like guide element and an ultrasound measurement element attached to a distal end of the ultrasound catheter; a special fluid duct; a fluid duct outlet opening of the special fluid duct arranged in the insulation sleeve proximal to the electrode head, the special fluid duct being adapted to convey a contrast means towards the electrode head; a sealing device provided at the fluid duct outlet opening and configured as a non-return valve, wherein the sealing device allows contrast means to flow through the special fluid duct and out from the fluid duct outlet opening but prevents a reverse flow into the electrode cable via the fluid duct outlet opening; wherein a sealing valve is arranged in a region of the electrode head that is axially distanced from the electrode head; wherein the path of the catheter duct extends directly to the sealing valve; and wherein when the appropriate pushing force is applied to the ultrasound measurement element, the appropriate pushing force opens the sealing valve and the ultrasound measurement element is moved through the sealing valve and past the electrode head.
