Intravascular inflatable medical devices and their methods of manufacture and use. The inflatable medical devices may include a conduit that includes an inflatable wall, with the inflatable wall defining a lumen therein. The inflatable wall may include an outer layer and an inner layer, and optionally an intermediate layer between the inner and layers. Intermediate layers may include one or more couplings between the outer and inner layers, and may include radial connectors extending between the outer layer and the inner layer.

An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

A method of connecting together two unit elements (4, 4′) of a fluid transport pipe, each unit pipe element being covered in an outer insulating coating (6, 6′) made of a thermoplastic material, with the exception of an end portion that does not have an outer insulating coating. The method includes: a step of welding together two abutting unit pipe elements; a step of positioning an annular sleeve (14) around a cut-back and in part around the outer insulating coatings of the two unit pipe elements, the sleeve being made of a thermoplastic material; a step of fastening the sleeve in sealed manner by weld bonding on the outer insulating coatings; and a step of applying an external pressure on the sleeve to enable it to be deformed elastically and match the shape of the respective end portions of the two unit pipe elements.

A cryogenic storage tank including a first metallic end piece having a first structured connection area on its outer surface, a second metallic end piece having a second structured connection area on its outer surface, a hollow body extending between the first structured connection area and the second structured area. The hollow body is formed of a fiber reinforced polymer-based composite, a first metallic clamp having a third structured connection area and a second metallic clamp having a fourth structured connection area. The hollow body is arranged between and in intimate contact with the first structured connection area of the first metallic end piece and with the third structured connection area of the first metallic clamp and is arranged between and in intimate contact with the second structured connection area of the second metallic end piece and with the fourth structured connection area of the second metallic clamp.

A set of sealing jaws incorporating an adjustable seal area to seal the vertical portion of a bottom gusseted style of package. An adjustable seal surface allows a packaging machine to run different film web widths without the need to change jaws. The sealing jaws to be converted to run bottom gusset packages to pillow packages without the requirement to change jaws.

A reusable plastic container is provided. The container includes a plastic container body having opposing side panels and opposing end panels. The container body also includes top side panel flaps attached to a top portion of each side panel, and bottom side panel flaps attached to a bottom portion of each side panel. The container body has top end panel flaps attached to a top portion of each end panel, and bottom end panel flaps attached to a bottom portion of each end panel. The top and bottom side panel flaps are each defined with respect to the side panels by a fold line. The fold lines including at least one scored portion and at least one welded portion.

The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125° C., and a melt index from 1 g/10 min to 50 g/10 min; and (ii) from 30 to 10 weight percent of an olefin-based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125° C.

A method of permanently joining composite parts made from thermoplastic material includes providing a first composite part and a second composite part, both made from thermoplastic material, wherein an orifice is provided in at least one of the composite parts, positioning both composite parts such that a portion of the composite part which includes the orifice is adjacent to a portion of the other composite part, injecting melted thermoplastic material through the orifice to contact the first and the second composite part in a contact area, whereby surfaces of the first and the second composite part in that contact area melt together; and solidifying the thermoplastic material in the orifice and in the contact area to permanently join the first composite part to the second composite part.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.
