Abstract: The present disclosure relates to a system and method for providing laser energy through a catheter towards a second end portion of the catheter. Based on a characteristic of the laser energy multiple types of ablation therapy may be implemented. A first ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a first characteristic. A second ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a second characteristic. The first ablation therapy may be an optical ablation therapy wherein the laser energy is directed at the target site as optical energy and the second ablation therapy may be a pressure wave ablation therapy wherein pressure waves are directed at the target site as pressure wave energy.
Abstract translation: 本公开涉及一种通过导管向导管的第二端部提供激光能量的系统和方法。 基于激光能量的特征可以实现多种类型的消融治疗。 当激光能量输送系统的第二端部处的激光能量具有第一特征时，第一消融治疗针对靶部位。 当激光能量输送系统的第二端部处的激光能量具有第二特性时，第二消融治疗针对靶部位。 第一消融治疗可以是光学消融治疗，其中激光能量作为光能被定向在目标部位，并且第二消融治疗可以是压力波消融治疗，其中压力波作为压力波能量指向目标部位。

Abstract: Methods and systems for removing an object, such as a lead, from formed tissue are provided. Specifically, a lead removal sleeve is configured to engage patient formed tissue at a dilation engagement point. The lead removal sleeve is configured to dilate the formed tissue around a lead, while providing an inner lumen with clearance for the lead to move within the sleeve. It is an object of the lead removal sleeve to support the formed tissue, and even forces of the formed tissue, with a structure of the sleeve as the lead is removed from a patient. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.
