    • A vascular prosthesis tester (10) for inducing stresses upon a vascular prosthesis (22) having a channel extending through the vascular prosthesis is disclosed. The tester includes a pump (18) adaptable to pressurize a fluid disposed within the channel to induce a radial stress upon the vascular prosthesis. The tester may further include a bend applicator (16) operable to induce a bending stress, a torque applicator (12) operable to induce a torque, a linear force applicator (52) operable to induce a linear force, and/or a stop (28) for inducing a lateral push stress upon the vascular prosthesis. A method of fatigue testing a vascular prosthesis contained within a fluid conduit is also disclosed. The method includes injecting a fluid within the inner channel and inducing a torque, bending stress, linear stress, and/or later push stress upon the vascular prosthesis.

    • A modular cooling system adapter for coupling to an orifice and applying pressure from a source of pressurized gas. The adapter includes a universal cooling orifice fitting for attaching the device to cooling system orifices of various sizes and configurations. The universal fitting preferably includes a plurality of steps having outer axially extending surfaces disposed at a slight negative angle to a plane parallel to the axial direction. The adapter may include a pressure adapter for coupling to a source of pressurized gas, such that the pressure adapter can be interchanged with other diagnostic tools including a valve assembly, a valve assembly incorporating a temperature probe and gauge and/or a pressure gauge. Additionally, the cooling system adapter is fully modular in that it allows quick disassembly for replacement of components and interchangeability of diagnostic tools.

    • An adapter for connection to an opening in a fluid containing vessel for applying a vacuum to the interior of the vessel is provided. The adapter includes at least partially concentrically disposed outer and inner sleeves, each having a generally conical shape and a generally radially extending opening in a side wall thereof. The inner and outer sleeves are rotatable relative to each other such that the extent to which the openings in the side walls of the inner sleeve and outer sleeve are aligned can be selectively adjusted. The inner and outer sleeves define a passage through the adapter extending from a proximal opening at a proximal end to a distal opening at a distal end of the adapter. The proximal end of the adapter is configured for connection to a vacuum source and the distal end is configured for insertion in and to sealingly engage the edge of the opening in the vessel.
    • 提供一种用于连接到用于向容器内部施加真空的流体容纳容器中的开口的适配器。 适配器包括至少部分同心设置的外套筒和内套筒,每个套筒具有大致圆锥形的形状和在其侧壁中的大致径向延伸的开口。 内套筒和外套筒可以相对于彼此旋转,使得可以选择性地调节内套筒和外套筒的侧壁中的开口对准的程度。 内套筒和外套筒限定穿过适配器的通道,其从近端的近侧开口延伸到适配器的远端处的远端开口。 适配器的近端构造成用于连接到真空源,并且远端构造成用于插入并密封地接合容器中的开口的边缘。
