Abstract: Delivery devices for delivering a self-expanding prosthetic heart valve are disclosed. The delivery device includes at least one cord is configured to selectively cinch the self-expanding prosthetic heart valve. The delivery device further includes at least one self-expanding release pin comprising a proximal segment, a distal segment, and an intermediate segment positioned between the proximal segment and the distal segment. The at least one self-expanding release pin includes a normal, expanded condition wherein the intermediate segment extends radially outward relative to a central axis of the spindle from the proximal segment to the distal segment. The delivery device further includes a capsule configured to be distally extended relative to the spindle to collapse the at least one self-expanding release pin from the normal, expanded condition of the at least one self-expanding release pin to a collapsed condition of the at least one self-expanding release pin.

Abstract: A precision delivery vehicle having a vehicle body assembly, a fixed wing system, a rotor system and a guidance system. The vehicle body assembly can retain a payload. The fixed wing system includes first and second wings coupled to the vehicle body for fixed wing flight. The rotor system includes a mast structure, a rotor hub rotatable about the mast structure and at least two rotor blades coupled to the rotor hub and rotatable with the rotor hub relative to the mast structure. The at least two rotor blades are movable between a collapsed configuration and a deployed configuration. In the collapsed configuration, the precision delivery vehicle is in fixed wing flight. Upon placement of the at least two rotor blades into the deployed configuration, the precision delivery vehicle is placed into rotative flight. The guidance system is structurally configured to direct the precision delivery vehicle to a target.

Abstract: Apparatus and methods for controlling yaw of a rotorcraft in the event of one or both of low airspeed and engine failure are disclosed. A yaw propulsion provides a yaw moment at low speeds. The yaw propulsion device may be an air jet or a fan. A pneumatic fan may be driven by compressed air released into a channel surrounding an outer portion of the fan. The fan may be driven by hydraulic power. Power for the yaw propulsion device and other system may be provided by a hydraulic pump and/or generator engaging the rotor. The generator may be used to charge a battery during autorotation or descending. Low speed yaw control may be provided by auxiliary rudders positioned within the stream tube of a prop. The auxiliary rudders may one or both of fold down and disengage from rudder controls when not in use.
