Disclosed are cardiac shunts and method of delivery, and in particular, to a shunt to reduce elevated left atrial pressure (LAP). The methods include forming a puncture hole between the left atrium and the coronary sinus, widening the puncture hole, and placing an expandable shunt within the widened puncture hole. A first catheter having a side-extending needle may be used to form a puncture into the left atrium. A second catheter extends along a guidewire and an expandable shunt with distal and proximal flanges is expelled therefrom into the puncture. The shunt defines a blood flow passage therethrough that permits shunting of blood from the left atrium to the coronary sinus when the LAP is elevated. The shunt is desirable formed of a super-elastic material and manipulated with control rods. The shunt defines a tilted flow tube that facilitates collapse into the catheter.

A tamper proof seal for egg cartons that is particularly suitable for transparent egg cartons is described The seal is typically located on the side rims of the tray and lid. The seal is comprised of first contact area on the tray rim and a second contact area on the lid rim. The first and second contact areas are mechanically engaged or bonded together to form a sealed area between the lid and the tray that prevents the lid from being opened from the tray. A tear-away section on the tray and lid rim surrounds the sealed area. The tear-away section allows the sealed area to be easily removed from the egg carton by tearing-away the sealed area from the rim thereby allowing the egg carton to be opened.

A plastic container suitable for hot-fill food packaging applications is disclosed which is characterized by walls of proportionately decreasing thickness from the mouth of the container to a predetermined collapsible point. The wall thickness is designed such that the container walls will collapse, or deform, only at the collapsible point during cooling after hot-filling of food product or during transportation of the container between locations of varying altitudes and pressures. The container preferably collapses in the base area such that the collapse is not visible to the consumer and also the collapse does not affect stability of the container while in use or during loading and storage. The container of the invention is advantageous in that it requires less plastic material to form than other known hot-fill containers, and also can be formed out of any suitable food-grade plastic material or by any process.

An elongated intravascular device having a frame configured for reversibly expanding in a patient's body lumen, which has a sleeve secured to the frame, and at least one sleeve-folding strut configured to fold the sleeve inwardly as the frame radially collapses in the patient's body lumen. Additional aspects of the invention are directed to methods of recovering such expanded frame type devices, and a recovery catheter configured for collapsing an expanded frame. The devices and methods of the invention facilitate the collapse of expanded frame devices, for repositioning or removal from the patient's body lumen.

Two embodiments of a foldable cover for protecting the occupant of a wheelchair or other wheeled vehicle is described. The foldable cover includes a frame having two sections, a back section and a top section cantileverable from the back section over the normal space provided for an occupant. A mounting bar for rigidly mounting the back section and, hence, the remainder of the foldable cover is provided with both embodiments. The back section is pivotally connected to the mounting bar for pivoting movement between a stowed position in which such cover is out of the way of the occupant in a protected position in which it and the cantilevered top section cooperate to cover the occupant.

A device, method and system for causing a controlled collapse of cavities formed within liquid droplets wherein a pressurized jet comprising a liquid and nanoparticle material produces droplets from the breakup of the jet stream. The liquid droplets may be irradiated with energy to produce and expand cavities formed within the droplets by irradiation of the nanoparticles contained within the droplets or alternatively, a volatile fluid with or without a metal nanoparticle may form the cavity. The droplets are collided with a target to collapse the cavities within the droplets. The irradiating (if provided) and colliding are timed to enhance implosion energy resulting from the cavities' collapse. The implosion energy and the fuel in the cavity may be used to activate and sustain a fusion reaction or from any other purposes.
