| 20090254078 | ABLATION ELECTRODE AND CATHETER ASSEMBLY FOR EPICARDIAL MAPPING AND ABLATION WITH DIRECTIONALLY FOCUSED RF ENERGY - The present invention provides various embodiments of electrodes and/or electrode tips for use in connection with ablation catheters and ablation catheter systems. In an embodiment, an electrode tip for an ablation catheter is provided, comprising an electrode carrier, a first electrode, and second electrode, each adapted to direct energy is various directions and configured to be selectively activated. In another embodiment, an electrode is provided that comprises an electrode body having an insulated portion to protect adjacent tissue from ablation while further adapted to direct energy in a downward direction towards the target tissue. Other embodiments of electrodes and/or electrode tips providing ablative elements that are directed laterally are also disclosed. Moreover, embodiments of several types of electrodes and/or electrode tips, which may include positioning, orientation, irrigating, cooling, and deflecting features, whether provided individually or in various combinations, are also disclosed. | 10-08-2009 |

| 20110028837 | Photodynamic-based myocardial mapping device and method - A photodynamic mapping device includes a shaft with a proximal end and a distal end, at least one optical electrode at the distal end of the shaft, and at least one optical fiber positioned inside the shaft. In embodiments, the at least one optical fiber extends from the distal end of the shaft and is coupled to the at least one optical electrode provided at or about an outer surface of the device. In an embodiment, at least one optical fiber is coupled, at or about the proximal end of the shaft, to a light source coupled and an optical sensor. An analyzer can be coupled to the optical sensor. Embodiments of such devices can be configured to deliver substances, such as photodynamic therapeutic substances. | 02-03-2011 |
| 20110160593 | INTRACARDIAC IMAGING SYSTEM UTILIZING A MULTIPURPOSE CATHETER - A three dimensional physiological mapping system utilizing an intracardiac echo catheter capable of being located in six degrees of freedom by a visualization, navigation, or mapping system. An echocardiography image of the intracardiac echo catheter may be projected within a geometric model of the visualization, navigation, or mapping system where the location of the projected image is adjusted in response to user input identifying a structure present in the echocardiography image and the geometric model. | 06-30-2011 |
| 20110160721 | Irrigated Catheter Employing Multi-Lumenal Irrigation Tubing - An irrigated catheter includes a catheter body having both proximal and distal irrigation passageways. A first fluid delivery tube feeds the proximal irrigation passageway and is fluidly isolated from the distal irrigation passageway, while a second fluid delivery tube feeds the distal irrigation passageway and is fluidly isolated from the proximal irrigation passageway. Typically, the first and second fluid delivery tubes will be unitary, at least through the catheter body. The overall shape of the first and second fluid delivery tubes, as well as their respective lumens, may vary as necessary for a particular application of the irrigated catheter. The system also includes an irrigation fluid source and at least one pump to deliver the irrigation fluid through the irrigation passageways. Typically, the pump will be a volume-driven pump, such as a rolling pump. | 06-30-2011 |
| 20110208165 | Seal for controlling irrigation in basket catheters - An exemplary basket catheter includes an outer tubing housing an inner fluid delivery tubing having at least one fluid delivery port. A plurality of splines are each connected at a proximal end of the splines to the outer tubing and at a distal end of the splines to the inner fluid delivery tubing. The inner fluid delivery tubing is operable to be moved in a first direction to expand the splines; and in a second direction to collapse the splines. A porous membrane is provided over at least a portion of the inner fluid delivery tubing. A seat is provided at a proximal end of the porous membrane between the porous membrane and the outer tubing and between the porous membrane and the inner fluid delivery tubing, the seal configured for irrigating between the plurality of splines of the basket catheter while preventing fluid ingress into the outer tubing. | 08-25-2011 |
