摘要： Apparatus and methods for ablation efficacy are described herein where a hood having a deployable elongated feature can extend beyond a distal face of the hood. The elongated feature can channel the energy to the deeper regions within the tissue (such as trabeculated regions or other tissue structures) such that the energy can be delivered to the target tissue despite small or large irregularities in the target tissue surface (or region) and/or changes in the relative distances between the hood and the target tissue.

摘要： Discloses herein are ablative catheters and methods of use. The catheters can include a cooling chamber for circulating cooling fluid within the catheter tip to reduce hot spots within the catheter tip and/or to reduce the formation of coagulum. A proximal cooling chamber can be positioned proximally to a thermal mass for cooling a proximal portion of the catheter. In addition, or alternatively, a distal cooling chamber can be positioned for cooling a distal portion of the catheter tip. The cooling fluid can flow the ablative catheter in an open, closed, or open and closed loop.
