Biodegradable self-expanding polymer stent has an outer diameter of 0.25-40 mm, length of 5-250 mm, and closed-cell wall structure formed by struts, where ratio of inner diameter values before crimping and after crimping is in a range of 3 to 5, and made of a copolymer obtained from L-lactide, D-lactide, D,L-lactide, meso-lactide, glycolide, ε-caprolactone, trimethylene carbonate, p-dioxanone and compounds comprising functional groups capable of photopolymerization; supramolecular structure of the copolymer is oriented substantially circularly in a transversal cross section of the stent. Method of manufacturing includes extruding a tube of a polymer material; annealing the extruded polymer tube; laser cutting the extruded polymer tube to form a stent workpiece; heating the stent to above glass transition temperature of the polymer, crimping the stent workpiece uniformly over the entire outer surface thereof, and quenching at about minus 20 degrees Celsius; placing the quenched stent on a delivery means.

A method of making a barbed microcatheter having fluid egress openings includes obtaining a barbed microcatheter blank having a hollow tube with a proximal end, a distal end, and an elongated lumen that extends between the proximal and distal ends of the hollow tube, and first and second flattened regions that extend along opposite sides of the hollow tube. The method includes removing material from the first and second flattened regions of the barbed microcatheter blank to form barbs projecting outwardly from the opposite sides of the hollow tube, and using cutting elements for forming fluid egress openings in a wall of the hollow tube that are in fluid communication with the elongated lumen of the hollow tube. The method includes forming a tissue anchor that is connected with the proximal end of the hollow tube, and securing a surgical needle with the distal end of the hollow tube.

Provided herein are blown films with encapsulated active agents, such as volatile anti-microbial agents, suitable for use as food packaging materials. Also provided herein are methods of manufacturing such blown films. The methods include extruding a bubble from molten polymers, dispensing active agents inside the bubble, and collapsing the bubble such that the bubble self-adheres to form a film with the active agents encapsulated.

A method for manufacturing a curved composite casing for a turbomachine, notably for a low-pressure compressor of an aircraft turbojet engine, includes the following sequence of steps: (a) draping a preform by automatic placement of carbon fibres on a concave form, referred to as a female form; (b) laying a glass-fibre ply on a convex form, referred to as a male form; (c) transferring the preform onto the convex form, covering the glass-fibre ply on the convex form. Step (b) laying includes a phase (α) of laying a metal strip and/or an epoxy profile on the convex form, then a phase (β) of covering the metal strip with the glass-fibre ply.

The disclosure relates to a deep-drawing apparatus for deep-drawing a continuously fed film web, an associated packaging machine, and a corresponding method. A cyclically sequenced forming station, which runs along from a start position to an end position and runs back from there to the start position is provided, wherein individual format plates are sequentially firstly connected up to a forming vacuum device and then with a following holding vacuum channel. The forming vacuum device is part of the cyclically moved forming station. The holding vacuum channel includes two interlocking telescopic channel portions, a first telescopic channel portion being part of the cyclically moved forming station, and a second telescopic channel portion being mounted statically relative to the fixed machine frame.

An anti-graffiti window film covering system that includes multiple polymeric film layers. Each layer includes a unique visual indicia to identify the number of sheets remaining in the system.

A system device and method for storing paint in which paint (2), either at a paint store or at home, is placed in a storage bag (1) that is sealed to create one or more packets (10). The packets may then be stored for use at a later date for touching up damaged or marked paint on walls and other surfaces.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.

A manufacturing method for an automotive vehicle component that includes the steps of: arranging at least a first skin capable of solidifying on a first half-mold of a mold; closing a second half-mold of the mold to form the first skin; then solidifying the first skin in the molding cavity defined between the first half-mold and the second half-mold. The second half-mold has a piercing element with at least one point-shaped end, and the method includes piercing by the piercing element of at least one through-hole in the first skin before solidification of the first skin.
