Patent ID: 8100860

Claim:
A device for localized agent delivery through the wall of a coronary vessel, comprising: an elongated member having a first end and a second end, wherein the elongated member is more flexible near the second end than near the first end; a longitudinal axis defined between the first and second end; at least one lumen substantially aligned with the longitudinal axis between the first end and the second end of the elongated member; a side exit port disposed proximal from the second end of the elongated member, the side exit port communicating with the at least one lumen and the elongated member being configured to preferentially bend at the side exit port; a second side exit port disposed opposite the first side exit port, whereby the flexibility of the elongated member near the side exit ports is increased and at least one of the side exit ports is biased toward the outer curve when the device is placed in a bend; at least one injection member disposed within the at least one lumen having a proximal end and a distal end, the distal end being movable from a first position within the at least one lumen to a second position through the first side exit port, the injection member further comprising an injection lumen placing the proximal and distal end in fluid communication; and a substantially arcuate member disposed along the elongated member near the side exit port, the arcuate member being configured to bias the elongated member toward a curved configuration.
