DELIVERY DEVICES, SYSTEMS AND METHODS FOR DELIVERING THERAPEUTIC AGENTS

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 The body may include an opening through which an agent may be delivered after the retractable member has been retracted within the device.
