摘要：A medical assembly and method are provided to effectively treat abnormaltissue, 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 tissueadjacent 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 thetwo organs can comprise the non-target tissue. In this case, the cooling shield maycomprise an actively cooled inflatable balloon, which can be disposed between the twoorgans when deflated, and then inflated. The inflatable balloon can be actively cooled bypumping a cooling medium through it. In another method, the cooling shield can beembedded within the non-target tissue. In this case, the cooling shield can comprise oneor 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 beactively cooled by pumping a cooling medium through them.
