  • Patent number: 8741262
    Abstract: The present invention concerns a therapeutically labeled napthodianthrone or phenanthro[1,10,9,8-opqra]perylene-7,14-dione compound, which comprises a chemical element or an isotope that has an unstable nucleus and emits radiation during its decay to a stable form sufficient to destroy neighboring cells or tissues for use in a targeted radiotherapy to enhance curability of a warm-blooded animal that has been subjected to a necrosis-inducing antitumor therapy. A particular advantage of present invention is that viable rim resistant to a necrosis-inducing antitumor therapy such as vascular targeting agent (VTA) can be supplemented by one single or repeated doses of a therapeutically radiolabeled small molecule necrosis-avid chemical compound treatment to enhance the curability.

  • Patent number: 6514251
    Abstract: Device for delivering radio frequency (RF) energy, for example during tissue ablation procedures, comprising an electrode having a distal end associated with tissue puncturing means and a proximal end connectable to a radio frequency energy source, wetting means for wetting the proximity of the distal end of the electrode with a non-toxic (RF) conductive solution and cooling means for cooling at least the distal end of the electrode. The invention further relates to a process for cooling and wetting a radio frequency energy delivering device and to a guidance element therefor.
