摘要:
The disclosure describes a breast implant device product that mimics the natural pectoral fat of the breast and is characterized by an incomplete pyramid with isosceles triangular base and wedge-shaped edges and sloping faces that meet at acute angles with variable degree located medially, laterally, and on the top and a footprint characterized by a semicircular lower portion and an oval paraboloid upper portion and a center of gravity located closer to the footprint than to the profile, the said footprint is advantageously converging and moving towards the underlying surface as the chest wall with a method of manufacturing and a method of use of the said implant including a breast pyramid sizing system.

One method for creating barrier products (for example, condoms and gloves) includes: (a) dipping a former into a tank of elastic compound. The former has an indentation extending inwardly from an outer surface for creating a first protrusion on a first face of the barrier product. The method further includes: (b) removing the former from the tank of elastic compound, whereby some of the elastic compound removably adheres to the former and fills the indentation; (c) applying supplemental material to the elastic compound, whereby creating a second protrusion on a second face of the barrier product; and (d) fully drying the supplemental material. One barrier product includes an elastic wall having opposed faces, and first and second protrusions respectively extend from the opposed faces. The first and second protrusions are in cross-sectional alignment whereby rotational input forces on the first protrusion create rotational output forces on the second protrusion.

The invention provides methods for producing flexible, stretchable, and/or elastic sheets and products having two or more zone having different material features and performance. The products can be comprised of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material of different types over different zones of a workpiece former or conveyor belt.

A method for producing a polyimide tubular member includes preparing a polyimide precursor solution, heating the polyimide precursor solution, coating a core with the heated polyimide precursor solution to form a coating film, drying the coating film, and baking the dried coating film to perform imidization.
摘要:
The present invention refers to a process and apparatus for manufacturing plastic articles through the rotational molding method, and is more particularly addressed to a process and apparatus of rotomolding in furnace for manufacturing containers with multiple layers. The apparatus of the present invention uses a series of bins for the introduction of the materials to be molten on the molds, which are controlled by a computerized control panel.

A system and method for automated manufacture of prosthesis shells using removably mountable mandrel is described. The mandrels are mounted onto cassettes, which are then moved through various dipping, devolatilization and curing steps by a robot, improving the uniformity of the shells and reducing cost of manufacture. The cassettes may include a motor to rotatably drive spindles upon which the mandrels are mounted on the cassette. The motor may be driven by a battery housed within the cassette to provide for untethered use of the cassette.
摘要:
A needle-like structure includes projections formed in rows on a substrate and extended in a direction, and needle portions formed on each of the projections such that the needle portions are spaced part from one another.
摘要:
A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent.
摘要:
A method is presented for forming a collapsed foam film-like structure, the method including positioning a composition applicator adjacent to a hot non-permeable dryer surface, producing a first frothed dispersion or frothed solution from a first dispersion or solution, applying the first frothed dispersion or frothed solution to the dryer surface, allowing the first frothed dispersion or frothed solution to convert to a collapsed foam film-like structure, and scraping the collapsed foam film-like structure from the dryer surface. The method can further include producing a second dispersion or solution, blending the first dispersion or solution and the second dispersion or solution, frothing the blended dispersion or solution, applying the blended frothed dispersion or frothed solution to the dryer surface, and allowing the frothed dispersion or frothed solution to convert to a collapsed foam film-like structure.
摘要:
A molding roller includes a cylindrical main body and a seamless ring-shaped molding film. The main body has a circumferential surface. The molding film is directly formed on the circumferential surface. The molding film has a molding surface opposite to the main body. The molding surface has a number of molding patterns. The molding film is made of polymer material, and the polymer material is obtained through the polymerization of polydimethylsiloxane and hard chain additive. The invention further relates to an apparatus and provides a method for manufacturing the molding roller.
