  • Publication number: 20030181908
    Abstract: Methods of sealing an injection site of a tissue are provided, where therapeutic agent has been injected into tissue, resulting in increased efficiency or agent uptake. Also provided are methods for delivering therapeutic agent to a tissue, which include injecting a therapeutic agent into a tissue and subsequently sealing the injection site, or engaging an injection device with the tissue for a sufficient period of time that sealing is not necessary to avoid leakage of the therapeutic agent. In one embodiment radio frequency cautery is used to seal the injection site upon needle removal from the tissue. In other embodiments, the injection site is sealed by resistance heating, laser heating or plugging the site with a solid plug or coagulating material at the site.

  • Publication number: 20030120202
    Abstract: A method and system for delivering a medical agent to targeted tissues in a patient, and subsequently removing systemically distributed medical agent to minimize exposure of non-targeted portions of a patient's body to the medical agent. The patient is treated with a targeted medical agent that includes a therapeutic component, a targeting component, and a magnetically attracted component. The targeting component, such as an antibody known to be attracted to an antigen present at the target, causes a concentration of the targeted medical agent to occur at the targeted tissue. The medical agent not concentrated at the targeted tissue is removed by withdrawing and magnetically filtering a portion of the patient's blood to remove the targeted medical agent, and returning the filtered blood to the patient.
