Method for positioning terminal end of pacemaker lead, which has passed through coronary sinus, in interventricular septum
First Claim
1. A method of positioning a tip of a pacemaker lead, which has passed through a coronary sinus, into an interventricular septum where a conduction system of a heart is positioned, in order to effectively transmit electrical stimulus, the method comprising:
- a step of positioning an intervention wire inserted through a superior vena cava and a coronary sinus into a right ventricle of a heart through an interventricular septum;
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 tip of the lead into the interventricular septum by inserting the pacemaker lead along the intervention wire.

Abstract
The present invention relates to a method for positioning a tip of a pacemaker lead that has passed through coronary sinus into an interventricular septum. More particularly, it relates to a method for positioning a tip of a pacemaker lead that has passed through a coronary sinus into an interventricular septum in order to more effectively transmit an electrical stimulus in a treatment using a pacemaker for patients with arrhythmia.
A method of positioning a tip of a pacemaker lead, which has passed through a coronary sinus, into an interventricular septum, in order to effectively transmit electrical stimulus, includes: inserting into an intervention wire through a superior vena cava and a coronary sinus to pass through the interventricular septum and then guiding the intervention wire to an inferior vena cava; and positioning the tip of the lead into the interventricular septum by inserting the pacemaker lead along the intervention wire.
