Abstract
A method is provided for delivering a drug to a selected tissue region within a patient's body with a catheter having a deployable puncturing element, a drug delivery element and an orientation element on a distal portion thereof. The distal portion of the catheter is percutaneously introduced into a blood vessel, and directed endovascularly to a vessel location adjacent to the selected tissue region. The puncturing element is oriented towards the selected tissue region, and deployed to access the selected tissue region. A drug is delivered with the drug delivery element to the selected tissue region.
