Abstract
This patent document discloses perfusion catheters and related methods for treating blood vessel lesions and abnormalities. A perfusion catheter can include an inflatable balloon, an elongate shaft operably attached to the balloon, and an optional containment structure surrounding at least a portion of the balloon. The balloon can be inflated until its outer surface contacts a wall of a blood vessel. When inflated, the balloon's inner surface defines a passage for blood to flow. The balloon can be configured to release one or more substances formulated to treat a tissue at or near the wall of a blood vessel. In an example, the balloon can include a bioactive layer, which comprises the one or more substances, overlaying an optional base layer. In an example, the balloon can include multiple filars, at least one of which is configured to elute the one or more substances through a perforation or hole in the filar.
