Plastic preforms are introduced into a blow mold and are expanded by applying a flowable medium thereto, which is introduced into the internal space of the plastic preforms, wherein the blow mold includes at least two lateral parts which form a cavity during the expansion of the plastic preforms, within which the plastic containers are expanded. The lateral parts are respectively provided on lateral part carriers that are moved relative to each other for opening and closing the blow mold. At least one arrangement of a lateral part carrier and the lateral part provided thereon has an expansion element that can have a gaseous medium applied thereto. The expansion element ensures, when the gaseous medium is applied thereto, that one lateral part is moved towards the other lateral part. During the expansion of the plastic preforms, at least two different pressure levels are applied.

A method and system for manufacturing a multi-lumen device that includes extruding a first layer of material to form an elongate body with a first lumen and a second lumen, the elongate body having a length of at least 100 feet, depositing a mesh layer over the first layer of material along the entire length of the elongate body, and extruding a second layer of material over the mesh layer along at least a portion of the length of the elongate body. The length of at least 100 feet may be considered a first length, the method further comprising cutting the elongate body into a plurality of shortened elongate bodies having a usable length, such as between approximately two feet and approximately six feet.

The method wherein plastic preforms are formed into plastic containers by application of a flowable medium wherein the plastic preforms are biased with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the plastic preforms, wherein at least one of these reservoirs is supplied with the flowable medium by a pressure supply device and wherein the flowable medium is returned at least temporarily from the plastic container to at least one of these reservoirs, wherein a pressure in at least one reservoir is controlled, and wherein a target pressure is compared with an actual pressure in this reservoir, and a value characteristic of this comparison is determined.

A method and device for forming plastic preforms into plastic containers has a plurality of forming stations each having application devices which apply a flowable medium at least a first pressure level, a second pressure level, a third pressure level and a fourth pressure level respectively, wherein the second pressure level is higher than the first pressure level, the third pressure level is higher than and the second pressure level and the fourth pressure level is higher than the third pressure level and wherein at least at times a bottom area of the plastic preform and/or plastic container is applied with the flowable medium.

A system for simultaneously forming and filling a container from a thermoplastic polymer preform with a carbonated liquid at ambient temperature. The system includes a mold that encloses the thermoplastic polymer perform, a stretching member that stretches the thermoplastic polymer preform, an injection head that inject the carbonated liquid, and a pressurization system. The pressurization system is configured to, with the carbonated liquid beverage at room temperature (68 F. to 77 F.), increase pressure of the carbonated liquid beverage to a pre-load pressure that is greater than the defined partial pressure of dissolved carbon dioxide in the resultant filled and sealed container at room temperature, to maintain the carbonated liquid beverage at rest and at the pre-load pressure prior to injecting into the preform.

A medical stent mold includes a tube having an interior passage sized and dimensioned to receive a stent assembly disposed at least partially about a central portion of a stent balloon. The medical stent mold may also include a housing forming a chamber through which the tube extends. The tube may include a thermally conductive material and may have a body portion that extends within the chamber and an end portion that is proximate the body portion and that extends away from the housing. Forced convection may be used to quickly heat and cool the tube. Methods of increasing retention of an expandable stent assembly on a stent balloon and of detecting a leak in a stent balloon are also included.
