摘要：
Delivery devices, systems, and methods are configured to increase the retention of the therapeutic agent, and thereby increase the dose of the agent delivered. The delivery device may include a delivery body and a retractable member configured to move with respect to the delivery body. The retractable member may include a puncture member configured to create a delivery channel at the treatment site. The body may include an opening through which an agent may be delivered after the retractable member has been retracted within the device.
