Abstract:
This disclosure provides design, material, preparation methods, and use alternatives for medical devices. An example stent includes an expandable framework and a plurality of tubular members disposed along the expandable framework. Each of the plurality of tubular members include a lumen extending therein. The example stent also include a coating, wherein the coating is applied directly to both the plurality of tubular members and the expandable framework.
Abstract:
A method for creating tubular inserts is useful for creating custom fitted inserts that correspond to the anatomy of a patient and solve the problem of pressure points, wear of the implant, damage to surrounding tissue, and denting. Surface measurements of the affected portion of a patient's internal cavity are obtained. Those measurements are used to design a core. The core is 3D printed with a soluble material. The core is wrapped with a thin filament or film such that the contours from the core develop on the outer surface of the covering. The covering is hardened and the core is dissolved away, leaving a custom-made implant device that can be deposited in the patient's cavity.
Abstract:
The present disclosure encompasses three-dimensional articles comprising flexible- composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three- dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form fiber- reinforced continuous shaped articles that are flexible and collapsible.
Abstract:
A panel assembly (10) with a multi-layer patch (14) may be used in any number of different applications in order to reduce noise or vibrations, provide thermal insulation, and/or improve the structural integrity of an underlying part. In an exemplary embodiment where the panel assembly is a vehicle part, the panel assembly (10) includes a main panel (12), a primary adhesive layer (16), and a multi-layer patch (14) that includes at least two individual patches (24, 26, 28) and at least one auxiliary adhesive layer (30, 32). The primary adhesive layer attaches the multi-layer patch to the main panel, and the auxiliary adhesive layer attaches the individual patches together. The size, shape, thickness and/or composition of the different layers of the multi-layer patch may be specifically chosen to exhibit certain sound and/or thermal damping properties.
Abstract:
A lining tube for rehabilitating sewers and effluent lines, with an inner film tube (2), which is produced by joining the edge portions (4a, 4b) of at least one film web (6), which has on its outer side a nonwoven layer (8), and with a reinforcing layer (10), which is arranged on the nonwoven layer (8) and comprises a roving (10) impregnated with a light-curable reactive resin and wound in particular in a helical form, is distinguished by the fact that the nonwoven layer (8) extends in the edge portions (4a, 4b) up to the respective longitudinal edge (6a, 6b) of the film web (6), that the edge regions (4a, 4b) of the film web (6) are placed one over the other in an overlapping region (12) with a width (B) of 0.1 to 10 mm, in particular 0.5 to 2 mm, and that arranged on the side (14) of the film web (6) opposite from the nonwoven layer (8) is a film strip (16) that is thermally welded to the film web and covers the overlapping region (12). The invention also relates to a method and an arrangement for producing such a lining tube.

Abstract:
Apparatus and methods are provided for making coated liners and/or tubular devices including such coated liners. A sleeve may be provided that includes an outer first surface and an inner second surface extending between first and second ends thereof, and a hydrophilic or other coating may be applied to the first. The coated sleeve may be cut between the first and second ends to create opposing edges extending between the first and second ends, and the cut sleeve may be reversed such that the coated first surface defines an inner surface and the opposing edges are disposed adjacent one another, thereby providing a coated liner. Optionally, a tubular structure, e.g., one or more reinforcing layers and/or or outer layers may be attached around the coated liner, thereby providing a tubular device including an inner surface with a desired coating.
