  • Publication number: 20060292077
    Abstract: In accordance with the present invention, a high intensity radiopaque contrast agent is disclosed. The agent may be coated on or incorporated within bulk material which may then be subsequently utilized to fabricate a radiopaque medical device. Primary effects through chemistry include higher radiopaque concentrations per unit weight of the radiopaque element or agent. Secondary effects include selective placement of the radiopaque elements which may further enhance the radiopacity of the device with reduced requirements of the radiopaque agent. Such a radiopaque contrast agent may be produced in various forms such as a dendrimer and/or incorporated as the end groups of polymeric chain. In addition one can incorporate biological and/or pharmaceutical agents in combination with the present invention.

  • Publication number: 20060264531
    Abstract: The present invention is directed to a medical device, specifically a prosthesis which utilizes a novel class of blends between biodegradable polymers and bioceramics for medical device applications allowing one to capitalize on the biodegradable nature of these two distinct materials while enhancing the strength of these devices through the addition of various amounts of bioactive ceramic and glasses to biodegradable polymers. The blend may be fabricated into a medical device such as a stent or a distal protection device, and may incorporate various agents to enhance radioapacity and/or pharmacological function. In addition, the blend may be used as a coating to a medical device.

  • Publication number: 20060019691
    Abstract: A methodology for percutaneously accessing the central ear artery of a rabbit may be utilized for inducing, treating and evaluating injuries therein to determine the pathology of the injuries and the safety and efficacy of the treatment. The central ear artery of a rabbit is similar to morphology to human coronary arteries. Accordingly, the study of the central ear artery of a rabbit will provide valuable information in the biology and identification of new treatments for restenosis, atherosclerosis and vulnerable plaque.

  • Publication number: 20050272806
    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. The drugs, agents, and/or compounds may also be utilized to treat specific diseases, including vulnerable plaque. Therapeutic agents may also be delivered to the region of a disease site.
