Abstract
A medical device, for example, an endoscope or catheter, includes local drug delivery capabilities for selectively delivering at least one drug in vivo. The local drug delivery may occur as the medical device is advanced through tortuous passageways of the patient's body or may occur after the medical device has reached its targeted destination. The medical device includes a drug agent, for example, carried in or on a hydrophilic or hydrogel coating disposed on the outside thereof. When the hydrogel or drug agent receives an appropriate signal, e.g., solution containing a triggering agent or triggering condition, e.g., heat or light, the hydrogel contracts or expands to squeeze out the drug from hydrogel. If electric current is provided as the signal, and the drug agent is charged, the drug agent is released by electrophoretic forces.
