RVOT wire capturing (RWC) system in mitral valve cerclage annuloplasty
A mitral cerclage annuloplasty apparatus includes a catheter with a blocking member and a capturing member. The blocking member is in the shape of a pigtail or a balloon, and is configured on the distal portion of the catheter preventing the catheter from traversing through an unsafe zone thereby enabling the catheter to pass through the safe zone. This prevents damage to critical cardiac tissues. The capturing member is adapted for pulling out a RVOT cerclage wire into the IVC, and comprises of an expandable and collapsible mesh so that the RVOT cerclage wire is captured and directed into the IVC through the safe zone. Thus the RVOT cerclage wire is passed through the RV without damaging the heart tissue forming a complete circle around the mitral valvular annulus.
