Placing a guide member into a heart chamber through a coronary vessel and delivering devices for placing the coronary vessel in communication with the heart chamber
First Claim
1. A system for placing a guide member through the wall of a patient'"'"'s heart so that the guide member extends through a coronary vessel and the wall of the heart into a heart chamber, the system comprising:
- an introducer sized and configured for placement through a coronary vessel and the wall of a patient'"'"'s heart into a heart chamber; and
a guide member sized and configured to be positioned in the introducer and placed through the coronary vessel and the heart wall into the heart chamber, the guide member having a proximal portion adapted to remain outside the heart and a distal portion adapted to be passed into and then back out of the heart chamber;
wherein the guide member is passed through the introducer and moves through the coronary vessel and the heart wall to a location within the heart chamber.

Abstract
A guide member positioned through a coronary vessel and the wall of the heart provides access to a heart chamber. A first end of the guide member is passed through the coronary vessel and the heart wall into the heart chamber, and then is passed back out of the heart chamber. The end of the guide member may then be used to deliver devices into the heart chamber to carry out various medical procedures. A conduit delivery system is coupled to the end of the guide member and is delivered into the heart chamber and then used to place a conduit in the heart wall to communicate the coronary vessel with the heart chamber.
