Abstract: The present disclosure pertains to an active agent delivery device for insertion into a blood vessel that includes: (1) a proximal end, a distal end, and an exterior surface between the proximal and distal ends; (2) a lumen extending from the proximal end to the distal end beneath the exterior surface and operable to facilitate blood flow through the blood vessel; (3) an active agent dispenser associated with the exterior surface and operable to release an active agent into the blood vessel; (4) an irrigation channel operable to remove materials from the blood vessel; and (5) an expandable structure at or near the distal end and operable to expand downstream the blood vessel region containing the device and localize released actives agent proximal to the region containing the device. The present disclosure also pertains to methods of using the device to deliver active agents into blood vessels of subjects.

Abstract: The present specification provides a device and method for controlling a winch parcel delivery system through an uncrewed aerial vehicle (UAV) or drone. The example apparatus contemplates the use of a winch that will attach to a hook with active and passive release mechanisms through a winch line. The apparatus is enabled to attach to a parachute recovery system. The apparatus can detect when the ground has been reached to enable safe delivery of parcels. The apparatus can removably attach to various types of drones.
