Abstract:

A dual compartment sandwich package fabricated of foamed polystyrene or the like and adapted to retain therein in appealing and acceptable form a sandwich including a hot meat portion, such as a hamburger, and a cool trimmings portion, such as lettuce and tomato. The package includes a base and cover having central rib means for rigidifying the package and preventing bending about the longitudinal and transverse axes thereof. There are four cooperating slots and tabs for temporary or secure locking of the cover to the base, which latter condition also forms an external seal to prevent heat exchange with the ambient atmosphere, while the central rib means form an internal barrier to prevent transfer of air and heat between the two compartments. A method of packaging a hot meat portion-cool trimmings portion sandwich, such as a lettuce and tomato hamburger sandwich for dispensing and final assembly by a customer in such a dual compartment package is also disclosed.

Abstract:

A balloon catheter is provided that includes a catheter shaft constructed for insertion into a blood vessel, a balloon mounted on the catheter shaft, and a heating device located within the balloon and arranged for heating fluid inside the balloon to permit heating of tissue by thermal conduction from the fluid to the tissue through a wall of the balloon. The balloon catheter is inserted into a blood vessel and the balloon is passed through the right atrium of the heart and into the coronary sinus of the heart. The balloon is inflated with the fluid, and the fluid is heated inside the balloon through use of the heating device, to cause heat to pass from the fluid to surrounding tissue by thermal conduction through the wall of the balloon.
