A gastric balloon apparatus. An apparatus is disclosed that is insertable into a patent's stomach for treatment of overweight. The balloon occupies a volume of the gastric lumen to provide a sensation of fullness after the consumption of only modest amounts of food. The balloon apparatus has a basic toroidal shape to prevent blockage of the entrance or exit lumens of the stomach and promote proper passage of food through the stomach, while protecting the stomach lining from ulceration and irritation. A series of toroidal balloons of graduated diameter may be joined by inner and outer sleeves to define a funnel-shaped apparatus which expands when food is ingested, thus satiating the patient with substantially reduced quantity of food. A balloon storage and insertion apparatus also is disclosed, whereby a gastric balloon according to the disclosure may be pre-inflated and stored ion a tube for later use, whereupon the pre-inflated balloon is deployed into the stomach. Various mechanisms are disclosed for providing a pre-determined deflation of an inserted balloon, permitting the deflated balloon to be excreted from the body.

One embodiment of the invention comprises a trocar and a reducer cap that magnetically attaches to the trocar. The trocar and the cap each include a magnetic member, at least one of which is a first magnet, and the other of which is either a second magnet or a non-magnetized magnetically permeable member. Including a magnet of sufficient strength in the trocar and/or the cap will create a magnetic field that automatically holds a surgical instrument having a magnetically permeable member at its tip in axial alignment with the cap or trocar lumen. Introduction of the surgical instrument into the lumen can be further facilitated by providing the trocar or cap lumen with a funnel-shaped opening. A lumen seal can be provided by one or more compliant toroidal seal members that expand radially inwardly when compressed axially by the magnetic attraction between the cap and trocar. The alignment feature is particularly advantageous when incorporated in a mini-trocar having a lumen on the order of 1-3 mm in diameter. In that case, a trocar cap can be a small disc magnetically attracted to the trocar to cover the lumen. Magnetic aligning devices according to the invention can be used internally of a patient or transdermally. Another embodiment of the invention is an ostium plug with a lumen therethrough that can be used in tubal sterilization. The plug is permanently implanted in the patient, but a cap is coupled magnetically to the proximal end of the plug to permit reopening of the lumen when desired.

A closed system for harvesting fat through liposuction, concentrating the aspirate so obtained, and then re-injecting the concentrated fat into a patient comprises as its main components a low pressure cannula having between about 7 to 12 side holes of about 1-2 mm by 2.0 to 4.0 mm, a spring loaded syringe holder with a helicoidal spring to apply a substantially constant pressure over the full excursion of the plunger, and a preferably flexible collection bag which is also preferably graduated, cylindrical over most of its body and funnel shaped at its bottom, all of which are connected through flexible tubings to a multi-port valve. The multi-port valve has two flutter/duck bill valves which restrict the fluid flow to a one way direction which effectively allows the syringe to be used to pump fat out of a patient and into a collection bag in a continuous manner. After the bags are centrifuged to concentrate the fat, the excess fluids are separated and the valve is re-connected to permit the syringe pump to reverse fluid flow to graft the concentrated fat back into the patient.

Solar-powered reactor for processing of slightly absorbing and transparent gases. An obvious path to providing storable, renewable energy is through solar dissociation of gas molecules. These dissociation products are the precursors of modern liquid and gaseous fuels such as hydrogen and methanol/ethanol. An apparatus and method using a solar concentrator (such as a focusing trough or dish) directed at the receiving end of a reactor are disclosed. A range of designs of reactors for the dissociation of gases, both those that absorb slightly in the visible spectrum and those that are transparent in the visible and only absorb in the infrared, is described. For slightly-absorbing gases, a funnel-shaped reactor that preheats the gas and concentrates sunlight is the indicated embodiment. A system for dissociating CO₂ using the invention is described. For transparent gases, a holraum embodiment is more appropriate for coupling solar energy into the gas. In both cases, heat from the hot stream of dissociated gas may also be used to produce electricity with a standard steam or Stirling cycle generator.
