摘要： A vacuum insulation tube assembly which is utilized as a component in a cryosurgical probe. The vacuum insulation tube assembly includes an inner tube; and, an outer tube concentrically positioned about the inner tube. The outer tube is securely soldered at end portions of the inner tube and forms a vacuum space between the inner tube and the outer tube. The vacuum tube assemblies may be conveniently mass produced using a special fixture.

摘要： The catheter includes a multi-lumen tube having an outflow portion and an accessory portion. The accessory portion is integrally formed within an interior volume of the outflow portion. The accessory portion has a cross-section smaller than the outflow portion. The outflow portion is offset from the accessory portion such that they are integrally joined. The space between these portions defines a fluid return passageway and the space within the accessory portion defines an accessory passageway. A flexible outer sleeve cooperates with the multi-lumen tube to form a fluid inlet passageway. During operation, an inlet flow of warming fluid flows through the fluid inlet passageway formed between the outer sleeve and the multi-lumen tube. The flow continues around a distal end of the outflow portion of the multi-lumen tube, thus becoming an outlet flow of the warming fluid which is directed through the fluid return passageway.
摘要翻译：导管包括具有流出部分和附件部分的多腔管。附件部分一体地形成在流出部分的内部容积内。附件部分的横截面小于流出部分。流出部分从附件部分偏移，使得它们整体连接。这些部分之间的空间限定了流体返回通道，并且附件部分内的空间限定了附件通道。柔性外套管与多腔管配合以形成流体入口通道。在操作期间，加热流体的入口流动流过形成在外套管和多腔管之间的流体入口通道。流体在多腔管的流出部分的远端周围继续，从而变成被引导通过流体返回通道的加温流体的出口流。

摘要： An inlet flow of heat exchange fluid flows from an inflow housing inlet section, and through an inflow housing main section. It then flows through an inlet fluid passageway formed between an inner balloon and a discharge tube. The flow continues around a distal end of the inner balloon, thus becoming an outlet flow of the heat exchange fluid which is directed through an outlet fluid passageway formed between the inner balloon and an outer balloon, then through an outflow housing main section and finally discharged through an outflow housing outlet section. The inner balloon is in a position offset from the central axis of the catheter. The offset relationship enhances the fluid dynamic properties of the catheter. It provides an increased turbulence, which, in turn, maximizes the heat exchange efficiency.
摘要翻译：热交换流体的入口流从流入壳体入口部分流过流入壳体主体部分。然后流过形成在内气囊和放电管之间的入口流体通道。流动继续围绕内球囊的远端，从而变成热交换流体的出口流动，该热交换流体被引导通过形成在内球囊和外球囊之间的出口流体通道，然后通过流出壳体主区段并最终排出通过流出的外壳出口部分。内囊处于从导管的中心轴线偏移的位置。偏移关系增强了导管的流体动力学特性。它提供了增加的湍流，从而使热交换效率最大化。
