Abstract
A delivery probe for delivering a therapeutic agent to tissue is described including at least one delivery capsule for accommodating the agent, at least one delivery device in fluid communication with the capsule, an actuation mechanism for moving the capsule between an activated position and an inactivated position by providing at least one of a fluid and a vacuum, and a delivery mechanism for forcing the agent out of the capsule. A method of delivering a therapeutic agent to tissue is also described including providing a catheter with a delivery probe at a distal end, positioning the delivery probe next to the tissue, supplying fluid to an actuation chamber to position the probe into an activated position, supplying fluid to a delivery chamber to force the agent out of the probe, and establishing a vacuum in the actuation chamber to position the probe into an inactivated position.
