Device and Method for Inserting a Cardiac Catheter

摘要

A device and method for implanting a catheter between the left atrium and/or left ventricle of the heart from a prepectoral region through a less invasive and lower-risk approach is provided that allows the implantation of the catheter in the left cardiac chambers through a femoral approach atrial transseptal puncture, and the removal of the catheter proximal end by a retrograde venous route. The device includes a transseptal sheath for slidably carrying the catheter, an elongate pulling element attached to a proximal end of the catheter, a runner slidable within the transseptal sheath and operable for biasing against the proximal end of the cardiac catheter, and a loop catheter having a loop formed at one end thereof, wherein the loop is dimensioned for receiving the transseptal sheath and for receiving the elongate pulling element therein when the loop and the elongate pulling element are separated from the transseptal sheath.

1. A method for implanting a catheter into the heart, the method comprising:
providing a catheter having a proximal end and a distal end; extending the catheter into an inferior vena cava; pushing the proximal end of the catheter for placing the distal end thereof into a right atrium of the heart; continuing to push the proximal end of the catheter for passing the distal end through a puncture in the interatrial septum of the heart; positioning the distal end of the catheter in the left atrium; and pulling the proximal end of the catheter into the superior vena cava.
