Abstract: The present application provides an arterial cannula system for transporting blood from an extracorporeal pump to a patient's femoral artery and aorta comprising first and second cannula portions. The first cannula portion has a proximal portion, a distal portion, and an intermediate portion and is configured for insertion through the femoral artery. It includes a first lumen extending from the proximal portion to the distal portion to deliver cardioplegic fluid, a second lumen communicating with an expandable occluding member at the distal end portion to inflate the occluding member to occlude blood flow, and a third lumen extending from the proximal portion to the intermediate portion to transport blood from the extracorporeal pump to the femoral artery. The second cannula portion is configured for insertion into the subclavian artery so that an opening in the distal portion is in communication with the aorta.

Abstract: A locking mechanism for a door which includes a locking member for securing an associated door in a closed position, apparatus for mounting the locking member to permit rotation about an axis, a first locking cylinder extending in a first direction which operatively cooperates with the locking member, and a second locking cylinder extending in a second direction which is opposite to the first direction, the second locking cylinder operatively cooperating with the locking member.

Abstract: A remote monitoring apparatus adapted for use with a commercial or private telephone communication system for activating a condition monitoring mechanism and converting the measured output thereof into data signals. The data signals are transmitted by the apparatus to a remote receiving station from which a triggering signal is derived to initiate operation of the data signalling apparatus.
