Abstract
Delivery devices, systems, and methods are configured to enhance retention of a therapeutic agent delivered at a treatment site, for example, via impeding agent backflow. A device may include sheath having a first end, a second end, and a length between the first end and the second end. The sheath may include an outer diameter and an inner channel between the first end and the second end, and at least one penetrating member configured to form a channel at the treatment site. The device may include an elongate member having a first end, a second end, and a length between the first end and the second end, the elongate member being configured to move relative to the sheath. The elongate member may be configured to control the movement of the penetrating member with respect to the sheath.
