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 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: An ablation catheter having a catheter shaft and a virtual electrode, the virtual electrode comprising portholes through an outer peripheral wall of the catheter shaft and a metal electrode, the catheter being used for treatment of cardiac arrhythmia, for example, atrial fibrillation, by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The catheter shaft includes a proximal portion and a distal portion. The distal portion includes an active region, which is either a looped structure transverse to the longitudinal axis of the catheter shaft, or a linear structure that extends parallel to the longitudinal axis of the catheter shaft. During use, the active region is directed into contact with, for example, the wall of a pulmonary vein. Upon energization, the virtual electrode creates a continuous lesion on an inner wall of the pulmonary vein, thereby electrically isolating the pulmonary vein from the left atrium.

Abstract: An ablation catheter used for treatment of, for example, atrial fibrillation by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The ablation catheter has a virtual electrode and a catheter shaft. The virtual electrode comprises a porous conductor. The catheter shaft includes a proximal portion and a distal portion. The distal portion includes an active region, which is either a looped structure transverse to the longitudinal axis of the catheter shaft, or a linear structure that extends parallel to the longitudinal axis of the catheter shaft. During use, the active region is directed into contact with, for example, the wall of a pulmonary vein and, upon energization, the virtual electrode creates a continuous lesion at or near the ostium of the pulmonary vein, thereby electrically isolating the pulmonary vein from the left atrium.

Abstract: A device for engaging a heart valve prosthesis during implantation includes a handle and a low profile holder. The handle has a proximal end and a distal end. The distal end is attached to the low profile holder which includes a distal engaging surface adapted for engaging the heart valve prosthesis. The distal engaging surface of the low profile holder maintains a leaflet of the heart valve in a closed position during implantation. This provides a low profile to the heart valve and holder which facilitates insertion through a trocar in a patient.

Abstract: An ablation catheter employing a continuous or nearly continuous flexible electrode arrangement. In one implementation, the flexible electrode include at least one electrode defining a saw tooth pattern. In another implementation, the flexible electrode is arranged in an interlaced pattern. Generally, the flexible electrodes are configured to adapt to the change in shape of the portion of the catheter that the electrode is connected with. Moreover, the flexible electrodes are arranged to provide a continuous or nearly continuous lesion of the target tissue. In some implementations, the flexible electrode may be connected with the catheter in a biased configuration, and as such may assist in changing the shape of a curve in the catheter.

Abstract: The present invention is a catheter actuation handle 14 for deflecting a distal end 18 of a tubular catheter body 12, the handle including an auto-locking mechanism, 54. The handle comprises upper and lower grip portions 24a, 24b, an actuator 20, and an auto-locking mechanism, 54. The auto-locking mechanism 54 is adapted to hold a deflected distal end 18 of the catheter 10 in place without input from the operator. When the distal end 18 of the catheter 10 is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator 20. The auto-locking mechanism 54 acts by providing a second force that resists this force from the distal end 18 and holds the distal end 18 in place. As a result, the operator does not need to maintain contact with the buttons 22a, 22b to maintain the distal end 18 in a set position once placed there by actuating the actuator 20.
