The present invention provides a method and device for production, extraction and delivery of an aerosol mist with ultrafine droplets. A high frequency wave generating device or other process generates very small particles or droplets from a reservoir of liquid or material to be atomized. A helical flow of a carrier gas medium such as air is directed into a container and creates a high throughput aerosol of air and fine droplets. The aerosol is delivered through a suitable outlet such as by deflecting the aerosol upwards and providing a tube centrally situated with respect to the helical flow such that the aerosol will discharge through the tube in high quantity of throughput and high quality of stable aerosol of very fine mist droplets. The methods described utilize in-situ extraction of fine mist droplets using helical flow behavior as opposed to forced convection ejection of mist or inertial separation of droplets by separators.

Techniques for routing a payload of a first network protocol, which includes header information for a second network protocol, include communicating a packet. In a circuit block, a first type for the first network protocol and a second type for the second network protocol are determined. The circuit block stores a classification that indicates a unique combination of the first type and the second type. A general purpose processor routes the packet based on the classification. Processor clock cycles are saved that would be consumed in determining the types. Furthermore, based on the classification, the processor can store an offset value for aligning the header relative to a cache line. The circuit block can store the packet shifted by the offset value. The processor can then retrieve from memory a single cache line to receive the header, thereby saving excess loading and ejecting of cache.

A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.

Methods and apparatuses relate to an implantable device for providing contractile assistance to an organ. The device may include an actuator and anchors located on either side of the actuator. The anchors engage with oppositely positioned tissue walls of an organ chamber, and provide contractile assistance to the organ, repeatedly, at appropriate times. For example, the device may be implanted within the right ventricle, anchored to the right ventricular free wall and the ventricular septum. The device may function to bring the opposing walls of the ventricle toward one another, synchronized with the pacing of the heart, resulting in an improved ejection fraction of blood from the chamber. In some embodiments, the actuator includes a bladder that is configured to contract upon receiving an inflow of pressurized fluid therein. When the fluid exits therefrom, the bladder relaxes back to an initial, extended state.

This invention relates to a method that comprises the introduction of a catheter via left subclavian vein, advancing into the right atrium and then positioning it in the inferior vena cava, just at the cava-diaphragm junction, where it is anchored at its extreme; and thereafter an external inflation of a balloon positioned in said catheter takes place through a physiological solution to reach a diameter corresponding to half the diameter of the inferior vena cava, resulting in hemi-occlusion in the expiration phase (breath-out) and total occlusion for a short period during the inspiration phase (breath-in), regulating (normalizing) the venous return and decreasing the cardiac volume overload, as a treatment for heart failure. The invention also comprises hydromechanics devices to normalize the venous return in the circulatory system. Said venous return is increased in 90% of patients with heart failure. In particular, it refers to a combined catheter with an inflatable balloon, producing said balloon a cyclical occlusion of the inferior vena cava (IVC). The said balloon is adaptable to the area of its location in the inferior vena cava, proximal to the right atrium (RA), which comprises of means for its fixation within said vein, as well as the capacity of modifying the volume in response to the requirements of the patient. This device is implanted for an extended period of more than three months. The final objective is to treat and stop the progression of heart failure.

Bombs lined with reactive liners that improve the blast and fragmentation of the bombs is disclosed. The effect is caused by the Richtmyer-Meshkov instability which is introduced at the explosive/reactive liner interface by introducing semi-cylindrical open linear cells between the reactive liner and the explosive that are void. This geometry produces a turbulent flow effect which readily mixes the reactive liner when accelerated by the grazing shock wave generated during detonation, which moves through the liner and case material. The geometry produces the added effect of creating faster and more plentiful fragments that are lighter in mass than those produced by typical bombs that are annularly lined with reactive liners, while maintaining insensitive munitions capability.
