Abstract
An apparatus and method for filtering intravascular fluids and for delivering diagnostic and therapeutic agents intravascularly is disclosed in which the apparatus has a shape defined by a preset shape of a resilient fiber core. The resilient fiber core is covered by a soft polymer tubing or other polymer material to form a delivery apparatus that takes the shape of the resilient fiber core. Various shapes and structures are disclosed that infuse diagnostic and therapeutic agents through a lumen of the polymer tubing, that deliver the agents in the form of a soluble coating, that circulate or contain a preloaded charge of radioactive material for intravascular radiotherapy, and that deploy filtration devices intravascularly for removing particulate matter from body fluid. The resilient fiber core and soft polymer material permit the construction of a very small apparatus that can be removed easily following treatment. Various deployment systems are disclosed for deploying the filtering and delivery apparatuses into a vessel and for protecting against radiation exposure.
