Method for positioning terminal end of pacemaker lead, which has passed through coronary sinus, in interventricular septum

A method of positioning a distal portion of a pacemaker lead, the method comprising:

• a step of positioning an intervention wire through a proximal septal vein a step of inserting a safe zone catheter inserted in an inferior vena cava into the right ventricle through a right atrium and a safe zone of a tricuspid valve;
• a step of inserting a guide wire through the safe zone catheter;
• a step of pulling out the safe zone catheter toward the inferior vena cava with the guide wire maintained in the right ventricle of the heart;
• a step of capturing the intervention wire with a capture catheter inserted along the guide wire;
• a step of pulling out the intervention wire captured by the capture catheter toward the inferior vena cava by pulling out the capture catheter toward the inferior vena cava with the guide wire maintained in the right ventricle of the heart;
• and
• a step of holding both ends of the intervention wire and positioning the distal portion of the lead into the interventricular septum by inserting the pacemaker lead along the intervention wire.
