    摘要： Devices, systems, and methods for sealing medical devices, particularly during intravascular access, are disclosed herein. Some aspects relate to a hemostatic valve for sealing a wide range of medical devices, such as catheters, wires, embolectomy systems. The valve can include an elongate member having a first end, a second end, and a central lumen extending therebetween. A reinforcement structure extends along at least a portion of the elongate member and is coupled to the elongate member. A shell defining a first aperture and a second aperture may be included, which first and second apertures can be fluidly coupled by the elongate member. A tensioning mechanism is coupled to the shell and to the elongate member, the tensioning mechanism can be moveable between a first configuration wherein the tensioning mechanism is collapsed and the central lumen is sealed and a second configuration wherein the central lumen is open.

    摘要： A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.

    摘要： Aspects herein relate to a low-friction septum for providing a leak-resistant seal for use in a vascular access device. In an embodiment, a device for vascular access hemostasis is included having an enclosure defining a cavity and configured to at least partially receive a medical device. The device can include a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The device can include a barrel in structural communication with the second seal portion, the second seal portion including a septum seal. The second seal portion can define two or more discrete portions, each separated by one or more split lines. The discrete portions can include a mating surface to interface with mating surfaces of other discrete portions. The mating surface can include a surface topology including raised portions and depressions. Other embodiments are also included herein.

    摘要： A medical valve assembly includes a tube extending between a first and second tube end along an axis, and a plunger plate extends radially from the second tube end. A valve housing surrounds the tube and includes a radially inwardly extending flange. A compression member is biased against the plunger plate and compresses an elastomeric seal from a non-compressed condition to a compressed condition to establish a sealed condition of the medical valve assembly. An inner surface of the elastomeric seal in the non-compressed condition has a plurality of planar portions and a plurality of radiused portions, with adjacent planar portions interconnected with one of the radiused portions to improve a closure of the elastomeric seal during compression. The inner surface preferably includes three planar portions and three radiused portions to define a generally triangular-shaped inner surface as viewed in cross section in the non-compressed condition.

    摘要： Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a proximal end region. A cartridge may be at least partially disposed within the proximal end region. The cartridge may include a seal member. The seal member may be designed to shift between an open configuration and a sealed configuration. A plunger, having an inner tubular region and a distal end, may be coupled to the proximal end region of the main body. The distal end of the inner tubular region may be spaced a clearance distance from a proximal end of the seal member so that when the seal member is in the sealed configuration and exposed to pressures of 80-250 pounds per square inch, the seal member deflects into contact with the distal end of the inner tubular region and remains in the sealed configuration.
