An intragastric device generally comprises a strip digestive-resistant mesh material that is operable between a first configuration and a second configuration. The first configuration is sufficiently small to permit introduction of the digestive-resistant mesh material into a gastric lumen of the mammal. The second configuration is sufficiently large to prevent the digestive-resistant mesh material from passing through the mammals pylorus, thereby permitting the mesh member to act as an artificial bezoar. Methods and devices for delivering the mesh member are also provided, including a pusher that is operable to engage and disengage the mesh member for delivery through the gastric lumen via a delivery sheath.

Integrated circuits, the key components in thousands of electronic and computer products, are generally built layer by layer on a silicon substrate. One common layer-formation technique, known as chemical-vapor deposition (CVD), produces uneven layers and covers vertical surfaces poorly. An emergent technique, atomic-layer deposition, overcomes these shortcomings, but has others, such as slow deposition rates and longer than desirable cycle times, particularly as applied to deposition of aluminum oxide. Accordingly, the inventors devised unique atomic-layer deposition systems, methods, and apparatus suitable for aluminum-oxide deposition. One exemplary system includes an outer chamber, a substrate holder, and a gas-distribution fixture that engages or cooperates with the substrate holder to form an inner chamber within the outer chamber. The inner chamber has a smaller volume than the outer chamber, which ultimately requires less time to fill and purge and thus promises to reduce cycle times for deposition of materials, such as aluminum oxide.

A wide-bandwidth antenna with antenna pattern control includes a radiator and a feed. The radiator includes two or more volumetric radiating elements. The feed includes two or more feed units, the feed units configured to provide wave signals to the volumetric radiating elements. The feed units provide an independent signal for each radiating element. The wave signals can be fed out of phase to each other. Depending on the dielectric filler inside the volume of the antenna and the phase shift between feeds, the pattern can be modified electronically leading to pattern control. The radiating elements are spaced at a distance at least one order of magnitude smaller than half of an operational wavelength of the antenna. At least one electrically conductive element of the antenna is capable of conducting a current that generates a magnetic field. The magnetic field lowers the total reactance of the antenna, thereby resulting in enhanced performance of the antenna in terms of bandwidth, gain, and pattern control. The volumetric design allows miniaturization of the antenna.

A patient is provided with an increased sense of satiety by increasing resistance to the outflow of food from the stomach and through the intestines. Stomach emptying may be slowed with devices implantable within the gastrointestinal tract below the stomach. Implants are preferably removable and can include artificial strictures that may be adjustable to vary the rate of stomach emptying. Slowing gastric emptying may induce satiety for a longer period and may therefore reduce food consumption. Many of the embodiments include intestinal liners or sleeves, but they need not. The resistor concept may be applied to a simple anchor and resistor without a long liner.

In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and / or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

Everting filter devices and methods for using the devices, including using the devices as intra-vascular filters to filter thrombus, emboli, and plaque fragments from blood vessels. The filter devices include a filter body nominally tubular in shape and having a large proximal opening. The filter body can extend from a proximal first end region distally over the non-everted exterior surface of the filter, further extending distally to a distal-most region, then converging inwardly and extending proximally toward the filter second end region, forming a distal everted cavity. The degree of eversion of the filter can be controlled by varying the distance between the filter first end region near the proximal opening and the closed second end region. Bringing the filter first and second end regions closer together can bring filter material previously on the non-everted filter exterior to occupy the distal-most region. The everting process can also bring filter material previously in the distal-most position further into the distal everted cavity. The filter devices can be used to remove filtrate from body vessels, with the filtrate eventually occluding the distal-most region. The filter can then be further everted, bringing fresh, unoccluded filter material into place to provide additional filter capacity. Some everting filters have the capability of switching between occluding and filtering modes of operation, thereby allowing a treating physician to postpone the decision to use filtering or occluding devices until well after insertion of the device into the patient's body.
