Abstract
A method including percutaneously positioning a delivery device in a blood vessel; locally introducing a treatment agent from the delivery device into the blood vessel upstream of an infarcted area or distressed area; and following introducing the treatment agent, occluding the blood vessel for a dwell time sufficient to allow the treatment agent to flow into targeted capillaries in or adjacent to the infarcted area. A system comprising a delivery device suitable for percutaneous insertion into a blood vessel of a patient, the delivery device comprising an occluding portion and a delivery cannula having a lumen therethrough; a controller coupled to a proximal portion of the delivery device comprising instruction logic to perform a method including introducing a treatment agent into the delivery cannula; and occluding a blood vessel following a predetermined delay time after introducing the treatment agent.
