ABSTRACT:
A drug-delivery tool and method for delivering a diagnostic or therapeutic agent to a target site within a selected body tissue, such as the myocardium of the heart, is disclosed. The drug-delivery tool generally includes an accessing device having a tissue-penetrating implement in its distal-end region, and elements for delivering a selected agent into a cavity formed by the implement. Methods of use are also described.
