  • Publication number: 20020164288
    Abstract: An contrast agent for therapeutic or diagnostic treatment comprises a fullerene scaffold and an iodinated moiety bonded to the scaffold. The agent may further comprise a water solubilizing moiety bonded to the scaffold, which may be a serinol malonodiamide, hydroxyl, and 1,3-diol. The fullerene scaffold may comprise an empty fullerene or an endohedral fullerene. A method for making the agent includes a) synthesizing iodinating moieties, b) protecting serinols, forming protected serinols, c) attaching the protected serinols to the iodinated moieties, forming iodinated serinols, d) attaching the iodinated serinols to the fullerene scaffold, and, optionally, d) de-protecting the serinols. Also disclosed are a method for providing diagnostic treatment to a patient comprising administering to said patient a radiopaque effective amount of a contrast agent comprising a fullerene scaffold and an iodinated moiety, a method of making a blood pool agent.

  • Patent number: 6475466
    Abstract: Disclosed are methods for treating endoleaks arising from endovascular repair of abdominal aortic aneurysms. The disclosed methods involve the in situ sealing of endoleaks after placement of an endovascular prostheses in the abdominal aorta. Sealing of endoleaks is achieved by injection of either a biocompatible polymer or prepolymer fluid composition into the endoleak which composition in situ solidifies to seal the leak. Preferably, the biocompatible fluid composition comprises a contrast agent to allow the clinician to visualize the sealing process.

  • Publication number: 20020090340
    Abstract: The invention provides compositions and methods for use in delivering a substance of interest to a targeted cell. The substance of interest is associated with a targeting fragment of a toxin molecule or a lectin that specifically binds to a cell surface receptor, such as the B subunit of an A/B type toxin molecule. The substance of interest may be a photosensitizing agent, in which case the cell (e.g. a cancer cell) may be killed by exposure to light after delivery of the agent. Alternatively, the substance of interest may be a visualizing agent that enhances visualization of the targeted cell.

  • Publication number: 20020031475
    Abstract: The invention relates to the use of intravenous contrast agents for projection mammography and novel devices for carrying out projection mammography. The invention therefore relates to the use of intravenous contrast agents for producing a diagnostic medium for projection mammography. With the additional intravenous administration of contrast agent, projection mammography attains a sensitivity comparable to the most modern methods, such as magnetic resonance tomography (MRT) while having a wider range of applications and avoiding the cost of MRT. This novel method is simple and can be carried out without special inconvenience for the patients. It a) considerably improves sensitivity for demonstrating focal lesions in the mammae and b) provides additional information on the character of previously detected lesions.

  • Patent number: 6217849
    Abstract: The present invention concerns injectable blood pool contrast agents for NMR and X-ray imaging purpose. These blood pool agents carry imaging contrast enhancers, e.g. paramagnetic or, respectively, radio-opaque compounds for imaging the circulation and/or circulation targeted organs. The blood pool agent compositions are formulated to protect the contrast agents from early removal by the reticulo-endothelial (RES) system of the liver and the spleen, so that they stay in the circulation long enough to provide good images of the blood vessels and blood perfused organs. X-ray and NMR imaging of the circulation and of targeted organs can strongly assist in diagnosing possible ailments in human and animal patients.

  • Patent number: 6207133
    Abstract: The invention relates to a new anti-tumoral therapy agent based on liposome-encapsulated cytostatic agents and/or the metabolites thereof. The invention can be used in the pharmaceutical industry and in medicine. The aim of the invention is to build up drug targeting to combat cancer through suitable carrier systems. The invention is characterized by the fact that it clearly increases the concentration of cytostatic agents and residence time in tumors. At the same time, toxic side-effects on the remaining organs are reduced. The inventive agent contains PEG, immuno or immuno/PEG liposome-encapsulated cytostatic agents and/or the metabolites thereof, degradable starch particles and/or gelatin and/or nanoparticles, contrast agents containing iodine, gadolinium or magnetite. A preferred agent is characterized by the cytostatic agent Carboplatinum, encapsulated in SUV-PEG, starch particle Spherex or Gelfoam and the contrast agent Gadolinium-DTPA.
