Abstract: A catheter employing fluid force to steer and/or shape the catheter. In one particular implementation, the catheter includes at least one actuating lumen operably associated with the shaft of the catheter. The at least one actuating lumen is in fluid communication with a valve or other fluid control means at its proximal end. The at least one actuating lumen extends along the length of the catheter shaft and terminates at some point along the length of the shaft. Upon introduction of fluid into the actuating lumen, the fluid creates a force which causes the catheter to bend. As such, fluid may be used to steer and/or shape the catheter.

Abstract: A transmyocardial implant establishes a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing on an exterior of the heart. The implant includes a coronary portion sized to be received within the vessel. A myocardial portion is sized to pass through the myocardium into the heart chamber. A transition portion connects the coronary and myocardial portions for directing blood flow from the myocardial portion to the coronary portion. The coronary portion and the myocardial portion have an open construction for permitting tissue growth across a wall thickness of the coronary portion and the myocardial portion. The myocardial portion includes an agent for controlling a coagulation cascade and platelet formation.

Abstract: An ablation catheter employing one or more manifold arrangements to convey a conductive fluid medium to a target tissue. The manifold includes at least one inlet port in fluid communication with a fluid supply lumen running along at least a portion of the catheter. The inlet port or ports are in fluid communication with a larger outlet port. The outlet ports provide an outlet for the fluid to flow out of the catheter and against the target tissue. As such, the combination of at least the inlet port with the outlet port provides a flow path for fluid within the fluid lumen to flow through the manifold and to outside of the catheter. An electrode is arranged in the flow path of fluid within or adjacent the manifolds. As such, fluid may be energized and conduct ablation energy to the target tissue to ablate the tissue.

Abstract: A device for engaging a heart valve prosthesis during implantation includes a heart valve prosthesis holder. The holder includes a distal engaging surface adapted for engaging the heart valve prosthesis. The distal engaging surface carries a compliant member which maintains an occluder of the heart valve in a closed position during implantation.
