TLDR
In this paper, a tissue ablation tip is positioned adjacent the tissue to be ablated using the visualization assembly and then activated using the transducer, which is then activated.Abstract:
Method and apparatus for ablation of cardiac tissue includes a catheter (2, 60) having an elongated flexible body (6, 64), a tissue characterization assembly including a transducer (34) at the distal end (16) of the body and a tissue ablation assembly having a tissue ablation tip (32) at the distal end of the body. The tissue ablation tip is positioned adjacent the tissue to be ablated using the visualization assembly and then activated.read more

Navigation system for cardiac therapies
TL;DR: In this paper, an image guided catheter navigation system for navigating a region of a patient includes an imaging device, a tracking device, and a controller, as well as a display that displays the image of the region with the catheter superimposed onto the image at the current location.
Patent
Method and apparatus for thoracoscopic intracardiac procedures
TL;DR: A tubular access device having an inner lumen is provided for positioning through a penetration in a muscular wall of the heart, the access device has a means for sealing within the penetration to inhibit leakage of blood through the penetration as discussed by the authors.

Patent
Ultrasonically enhanced RF ablation catheter
TL;DR: An electrosurgical angioplasty catheter with ultrasonic enhancement is described in this paper, which comprises an elongated, flexible plastic tubular body having located at its distal tip an electrode structure for effecting rf cutting along with a transducer for ultrasonically driving the cutting electrodes and the support thereof.
Patent
Thermal angioplasty catheter and method
TL;DR: In this article, a method and apparatus for selectively heating an atheromatous mass which partially or fully occludes a particular blood vessel is presented, allowing the occlusive mass to be more readily recanalized by expansion of a balloon or other dilitation means.
Patent
Device and method for heating tissue in a patient's body
TL;DR: In this paper, a balloon is mounted on the catheter shaft and filled with an electrically conductive fluid, two or more electrical contacts enclosed within the chamber, a power supply for applying an electrical potential to the contacts, and a two-or more conductors for connecting each of the contacts to the power supply.
