A method of manufacturing a bundled mat construction for an extracorporeal blood circuit heat exchanger includes attaching a leading edge of a first capillary tube mat segment to a first side of a mandrel. A leading edge of a second capillary tube mat segment is attached to a second side of the mandrel. The first side is diametrically opposite the second side. The mandrel is rolled relative to the mat segments to generate a bundled mat construction. Radial layers of the bundled mat construction are symmetrical relative to a central axis of the mandrel.

An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.

A capillary tube bundle sub-assembly for use in an extracorporeal heat exchanger includes a continuous capillary tubing wound about a core to define a plurality of capillary layers each including a plurality of capillary segments. The capillary segments each define opposing terminal ends adjacent opposing ends of the core. The capillary segments of each layer are circumferentially aligned relative to an axis of the core, with each successive layer being radially outward of an immediately preceding layer. The capillary segments are non-parallel with the axis, spiraling partially about the axis in extension between the opposing terminal ends. Each capillary segment forms less than one complete revolution (i.e., winds less than 360°). The segments within each layer are substantially parallel with one another; however, an orientation of the segments differs from layer-to-layer such as by pitch or angle.

A flexible carrier for carrying a plurality of containers includes a flexible sheet and a plurality of container receiving apertures formed in the flexible sheet. An array of the container receiving apertures extend longitudinally across the flexible sheet wherein each container receiving aperture is substantially rectangular and includes an aperture perimeter that increases more than 42% following application to a container.

A carrier and method of manufacture for a carrier that results in a package of containers includes a plastic sheet having an array of container apertures and a portion having a matte finish where the matte finish includes a lower coefficient of friction relative to a container than a remaining surface of the plastic sheet. A plurality of containers are each positioned within an aperture of the array so that the matte finish of the plastic sheet is positioned along an inner portion of the package and the remaining surface of the plastic sheet is positioned along an outer portion of the package.

Eligible entries are scheduled using an approximated finish delay identified for an entry based on an associated speed group. One implementation maintains schedule entries, each respectively associated with a start time and a speed group. Each speed group is associated with an approximated finish delay. An approximated earliest finishing entry from the eligible schedule entries is determined that has an earliest approximated finish time, with the approximated finish time of an entry being determined based on the entry's start time and the approximated finish delay of the associated speed group. The scheduled action corresponding to the approximated earliest finishing entry is then typically performed. The action performed may, for example, correspond to the forwarding of one or more packets, an amount of processing associated with a process or thread, or any activity associated with an item.

A flexible carrier for carrying a plurality of containers includes a flexible sheet having two rows of container apertures formed therein. The plurality of containers are each placed into a respective container receiving aperture and are thus unitized in a package. The flexible carrier further includes two handles, each handle formed at a periphery of the flexible sheet along each longitudinal edge of the flexible sheet and a line of weakness formed between the longitudinal rows. As a result of the described configuration, flexible carrier is divisible into two sub-carriers, each unitizing a set of containers and each including a handle along a respective longitudinal edge of the resulting sub-carrier.
