Method and kit for transvenously accessing the pericardial space via the right atrium

Abstract From the Canadian patent

A method and kit for accessing the pericardial space take advantage of the fact that the right auricle is a thin-walled low-pressure structure which can , be readily penetrated without damaging the pericardium or the epicardium. The kit includes an infusion guid wire and a leading guide wire having a diameter sufficiently small to be passed through a lumen of the infusion guide wire. The leading guide wire has a sufficient length to pass through and protrude from a distal end of the infusion guide wire. The leading guide wire also has a distal end capable of penetrating a wall of the right atrium of the subject's heart. The infusion guide wire and the leading guide wire both have …
