Abstract:
1. An agent delivery catheter comprising: a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body including an inflation lumen and a delivery lumen, each lumen extending from the catheter proximal portion toward the catheter distal portion; an inflatable balloon coupled near the catheter distal portion, the inflatable balloon in fluid communication with the inflation lumen and extending around at least a portion of the catheter body, the inflatable balloon including: an exterior balloon surface, a proximal and a distal shoulder portion, and a well portion between the proximal and distal shoulder portions; and an agent delivery tube extending along the exterior balloon surface, the agent delivery tube including at least one delivery orifice positioned outside of the exterior balloon surface and adjacent to the well portion, the agent delivery tube in fluid communication with the delivery lumen; wherein the inflatable balloon is configured for dilation from a stored configuration to a deployed configuration such that: in the stored configuration the inflatable balloon has a stored perimeter, and in the deployed configuration the proximal and distal shoulder portions each have a shoulder perimeter greater than the stored perimeter and the well portion has a well perimeter recessed relative to the shoulder perimeter, wherein the at least one delivery orifice opens into a volume between the proximal and distal shoulder portions and the well portion;
