Universal cardiac introducer
First Claim
1. A heart access manifold having an interior within a manifold wall, an exit port through the manifold wall and at least one entry port through the manifold wall, the exit port being adapted to sealably engage about an opening in a wall of the heart for communication with the interior of the heart to place the interior of the manifold to be under the same pressure as the interior of the heart, the at least one entry port providing access through the manifold wall into communication with the interior of the heart via the exit port, each entry port sealable to maintain pressure on the interior side of the manifold, each entry port adapted for passage therethrough to the interior of the manifold of at least one implement while maintaining pressure in the interior of the manifold.

Abstract
The present invention may be characterized as a heart access manifold having a manifold wall and at least one exit port and one entry port. The exit port through the manifold wall is adapted to be sealably engaged about an opening in the wall of a heart for communication with the interior of the heart and with the interior of the manifold to be under the same pressure as the interior of the heart. At least one entry port is provided through the manifold wall to provide access through the manifold wall into the interior heart via the exit port. Each entry port is sealable to maintain pressure on an interior side of the manifold wall. The entry port is adapted for passage therethrough to the interior side of the manifold wall of at least one implement in sealed relation so as to maintain pressure on the interior side of the manifold. The implement may be one which is selected to perform any operation that is desired or necessary within the interiors of the manifold or the heart. Suitable implements include microwave or ultrasonic probes, knives, cutters, staplers, holders, clamps, suturing devices, lasers and the like which are useful for carrying out procedures within the interior of the heart.
