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

Abstract

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 a 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. An apparatus for 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, includes: a intervention wire connected through a inferior vena cava, a coronary sinus, an interventricular sinus, a right ventricle, and an inferior vena cava; a surgical catheter passing through the inferior vena cava and a safe zone to capture the intervention wire positioned in the right ventricle; and a pacemaker lead inserted along the intervention wire such that the tip is positioned in interventricular septum tissues.

         7 . The apparatus of  claim 1 , wherein a blocking member being locked at an unsafe zone of a tricuspid valve, but freely passing through a safe zone of the tricuspid valve in order to allow the surgical catheter to safely pass through the safe zone that does not injure the tricuspid valve is formed at a front end of the surgical catheter, and a capture catheter being inserted through the inferior vena cava and the coronary sinus and capturing the intervention wire to pull out the intervention wire inserted in the right ventricle toward the inferior vena cava is formed under the blocking member. 
     
     
         8 . The apparatus of  claim 1 , wherein the surgical catheter includes: a safe zone catheter having a blocking member being locked at an unsafe zone of a tricuspid valve, but freely passing through a safe zone of the tricuspid valve in order to allow the surgical catheter to safely pass through the safe zone that does not injure the tricuspid valve is formed at a front end of the surgical catheter, and a capture catheter being inserted into the inferior vena cava and being inserted into the right ventricle through a right atrium and the safe zone of the tricuspid valve to capture the intervention wire. 
     
     
         9 . The apparatus of  claim 1 , wherein a hole for inserting the intervention wire is formed in the pacemaker lead and the tip of the pacemaker lead is pointed to easily penetrate the interventricular septum tissues. 
     
     
         10 . A catheter for 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 catheter comprising a balloon having a hole therein for passing a intervention wire therethrough and formed at a front side to be inflated by air from the outside so that a septal vein positioned in an interventricular septum is easily found by blocking the coronary sinus. 
     
     
         11 . A dual lumen catheter that is an interventricular septum lumen catheter for 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 dual lumen catheter comprising: a first tube supported by a support wire passing through the first tube; and a second tube fixed in contact with a side of the first tube and passing the intervention wire for boring the interventricular septum therethrough. 
     
     
         12 . The dual lumen catheter of  claim 11 , wherein a radiopaque marker is formed on the catheter so that location of an end of the second tube positioned in the coronary sinus is easily found. 
     
     
         13 . The dual lumen catheter of  claim 11 , wherein an inclined guide is formed at the end of the second tube to allow the intervention wire to pass through the end at an angle and penetrate the interventricular septum.
