    Abstract: According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.

    Abstract: A medical assembly and method are provided to effectively treat abnormal tissue, such as, a tumor. The target tissue is thermally ablated using a suitable source, such as RF or laser energy. A cooling shield is placed in contact with non-target tissue adjacent the target tissue, and actively cooled to conduct thermal energy away from the non-target tissue. In one method, the cooling shield can be placed between two organs, in which case, one of the two organs can comprise the target tissue, and the other of the two organs can comprise the non-target tissue. In this case, the cooling shield may comprise an actively cooled inflatable balloon, which can be disposed between the two organs when deflated, and then inflated. The inflatable balloon can be actively cooled by pumping a cooling medium through it. In another method, the cooling shield can be embedded within the non-target tissue. In this case, the cooling shield can comprise one or more needles. If a plurality of needles is used, they can be embedded into the non-target tissue in a series, e.g., a rectilinear or curvilinear arrangement. The needle(s) can be actively cooled by pumping a cooling medium through them.

    Abstract translation: 提供医疗组件和方法来有效地治疗诸如肿瘤的异常组织。 使用适当的来源（例如RF或激光能量）将靶组织热消融。 将冷却屏蔽物放置成与目标组织相邻的非靶组织接触，并且主动冷却以将热能从非目标组织传导出去。 在一种方法中，冷却屏蔽可以放置在两个器官之间，在这种情况下，两个器官中的一个可以包括靶组织，并且两个器官中的另一个可以包括非靶组织。 在这种情况下，冷却屏蔽件可以包括主动冷却的可膨胀气囊，当气体放气时可以将气囊放置在两个器官之间，然后膨胀。 可以通过泵送冷却介质来主动冷却可充气球囊。 在另一种方法中，冷却屏蔽可以嵌入在非目标组织内。 在这种情况下，冷却罩可以包括一个或多个针。 如果使用多个针，则它们可以以一系列例如直线或曲线布置被嵌入到非目标组织中。 可以通过将冷却介质泵送通过它们来主动冷却针。

    Abstract: A method of treating abnormal tissue within a patient includes positioning a delivery cannula within the patient, the delivery cannula having a first electrode disposed on its distal end; introducing an ablation probe through the cannula and out an open distal end thereof, so that a second ablation electrode carried on the ablation probe contacts abnormal tissue within the patient; conveying ablation energy between the first and second ablation electrodes to ablate the abnormal tissue; and introducing a separate medical element, whether a device or a therapeutic agent, through the cannula before or after the ablation process.
