Abstract: 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.

Abstract: An oxygenator apparatus for use in an extracorporeal circuit. The apparatus includes a housing and a membrane assembly disposed within the housing. The membrane assembly includes a first plurality of gas exchange elements disposed in a first zone and a second plurality of gas exchange elements disposed in a second zone. The second zone is arranged concentrically around the first zone. The first and second plurality of gas exchange elements are fluidly open along a body and fluidly separated along a distal end. The first zone is configured to be fluidly coupled to an oxygen source and the second zone is configured to be fluidly coupled to a negative pressure source. A blood flow path includes a generally radial flow through the first zone to add oxygen to the blood and the second zone to separate gaseous micro emboli from the blood through the plurality of gas exchange elements.

Abstract translation: 用于体外热交换器的毛细管束子组件包括围绕芯缠绕的连续毛细管，以限定多个毛细管层，每个毛细管层包括多个毛细管段。 毛细管段各自限定与芯的相对端相邻的相对的末端。 每个层的毛细管段相对于芯的轴线周向对准，每个连续层在紧邻的前一层的径向外侧。 毛细管段与轴不平行，部分地围绕相对端部之间延伸的轴线螺旋形。 每个毛细管段形成少于一个完整的旋转（即，风小于360°）。 每个层内的段基本上彼此平行; 然而，片段的取向不同于层间层，例如通过间距或角度。
