Abstract
One aspect of the present invention relates to a method for passing a fluid through a shunt located in the wall of a heart, the shunt providing fluid communication between a heart chamber and a coronary artery, with a hollow catheter. Another aspect of the present invention relates to a method of inserting a wire through a shunt located in the wall of a heart with a hollow catheter. A further aspect of the present invention relates to passing fluid through a shunt located in the wall of a heart, the shunt providing fluid communication between a heart chamber and a coronary artery, by injecting fluid into the heart chamber. A further aspect of the present invention relates to a catheter with a flexible, hollow, inner member to which a self expanding basket is attached. A further aspect of the present invention relates to a method of passing a radio-opaque contrast fluid through a shunt located in a heart wall, the shunt providing fluid communication between a heart chamber and a coronary artery. A further aspect of the present invention relates to inserting a wire into a coronary artery through a shunt located in a heart wall, the shunt providing fluid communication between a heart chamber and the coronary artery. A still further aspect of the present invention relates to a catheter including an inner tube with a self-expanding basket and an outer sheath about the inner tube. A further aspect of the present invention relates to a catheter with a flexible inner member with a shunt locating element at a distal end and an outer sheath about the inner member.

43. A device for delivering an implantable medical device to a target site in a heart along a predetermined pathway, comprising:
-
a generally straight first portion extending from a proximal end to a distal end;
a curved second portion extending from the distal end of the first portion to a distal end of the device, the curved second portion including a first curve portion formed in a first plane and a second curved portion formed in a second plane substantially orthogonal to the first plane to direct the implantable medical device toward an epicardial surface of the heart directly adjacent to the predetermined pathway. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. A system for delivering an implantable medical device to a target site in a heart along a predetermined pathway through a coronary vessel, comprising:
-
a delivery catheter having a generally straight first portion extending from a first proximal end to a first distal end and a curved second portion extending from the first distal end to a distal end of the delivery catheter; and
a therapy delivery device, slideably receivable within the delivery catheter, extending from a second proximal end to a second distal end, wherein the curved second portion includes a first curve portion formed in a first plane and a second curved portion formed in a second plane substantially orthogonal to the first plane to direct the therapy delivery device outward from the distal end of the delivery catheter toward an epicardial surface of the heart directly adjacent to the coronary vessel. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
