CATHETER BASED APICAL APPROACH HEART PROSTHESES DELIVERY SYSTEM
First Claim
1. A delivery system for rapid placement of heart implants at a mitral valve, comprising:
- a delivery platform, comprising;
a tubular catheter body being sufficient long and flexible to be advanced from a peripheral blood vessel access site to an atrium of the heart;
a piercing member configured to be advanced from the tubular body to create a transapical channel from an internal apical portion of a ventricle to an outside heart wall;
a delivery platform configured to be advanced from the tubular catheter body, the delivery platform comprising an elongate tension member and an enlargeable member disposed on a distal portion of the elongate tension member, the enlargeable member configured to be enlarged in a pericardial space of an intact chest wall to cover an area of the outside heart wall surrounding an opening of the transapical channel; and
a heart valve implant catheter;
wherein at least the heart valve implant is separable from the delivery system such that the tension member and anchor can be removed while leaving the heart valve implant in place.

Abstract
A delivery system for rapid placement of heart implants is provided that includes a delivery platform. The delivery system includes a tubular catheter body, a piercing member, and a delivery platform. The tubular catheter body is sufficiently long and flexible to be advanced from a peripheral blood vessel access site to an atrium of the heart. The piercing member is configured to create a transapical channel from an internal apical portion of a ventricle to an outside heart wall. The delivery system includes an elongate tension member and an enlargeable member disposed on a distal portion of the elongate tension member. The enlargeable member is configured to be enlarged in a pericardial space of an intact chest wall to cover an area of the outside heart wall surrounding an opening of the transapical channel. When tensioned, the tension member provides a stable zone for positioning a heart implant within the heart.
