Systems and methods for delivering drugs or other substances to target locations outside of blood vessel lumens or other body lumens. In some embodiments, a catheter having a penetrator is advanced into the body lumen and the penetrator is then advanced from the catheter toward a target location outside of that body lumen. The substance is then delivered through a the penetrator itself or through a delivery catheter that has been advanced through the penetrator to the target location. In other embodiments, the blood vessel or other body lumen is blocked at spaced-apart first and second locations and a quantity of the substance is introduced into the closed-off body lumen between the blocked first and second locations. The substance then diffuses into or through the wall of the vessel or body conduit to reach the target location.

Systems and methods for delivering drugs to selected locations within the body

A transvascular system for delivering a drug to a tissue region from a blood vessel includes a catheter having a distal portion with puncturing, orientation, drug delivery, and imaging elements. The puncturing element is deployable for penetrating the vessel wall to access the tissue region. The orientation element has a predetermined relationship with the puncturing element, the imaging element detecting the location of the orientation element with respect to the tissue region to orient the puncturing element. The catheter is percutaneously introduced into the vessel, the puncturing element is oriented towards the tissue region, the puncturing element is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter may be advanced into and left in the tissue region.

A transvascular system () for delivering a drug to a tissue region from a blood vessel, such as a coronary vein, includes a catheter () having a distal portion () with puncturing (), orientation (), drug delivery (), and imaging elements (). The puncturing element () is deployable for penetrating the vessel wall to access the tissue region. The orientation element (), e.g. a 'cage' including a plurality of struts () () and/or a radiopaque marker, has a predetermined relationship with the puncturing element (), the imaging element () detecting the location of the orientation element () with respect to the tissue region to orient the puncturing element. The catheter () is percutaneously introducing into the vessel, the puncturing element () is oriented towards the tissue region, the puncturing element () is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device () may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter () may be advanced into and left in the tissue region.

An implantable reservoir device () including an enclosed membrane () on an expandable frame () that defines a reservoir () and includes a porous region (). The reservoir device () may be deployed and expanded within a blood vessel, and may be filled in situ or prefilled with a drug that passes through the porous region (). Alternatively, a pair of expandable endovascular blockers () may be used to isolate a section of a blood vessel which may be filled with a drug that may be absorbed by the surrounding tissue.

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.
