    Abstract: A valve comprises a first housing including a first lumen extending therethrough and defining a first disk-facing surface and a second housing including a second lumen extending therethrough and defining a second disk-facing surface, the second housing being mated to the first housing so that the second disk-facing surface faces the first disk-facing surface in combination with a flexible disk gripped between gripping portions of the first and second disk-facing surfaces, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a predetermined threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level remains sealed preventing fluid flow between the first and second lumens and a relief well between opposing portions of the first and second housings radially outside the gripping portions, a width of the relief well exceeding a width of a radially outer portion of the flexible disk so that the radially outer portion of the disk is free to move therewithin.

    IPC: A61M25/00

    Abstract: A catheter that comprises a hub, an elongated conduit, and at least one lumen therein. The lumen includes a proximal lumen section, a distal lumen section, and an intermediate lumen section extending between the proximal and distal lumen sections. The cross-sectional dimension of the intermediate lumen section is less than the cross-sectional dimension of the distal lumen section. In one embodiment, the cross-sectional dimension of the intermediate lumen section is less than the cross-sectional dimension of the proximal lumen section. In certain embodiments, the lumen tapers from the distal and/or proximal lumen sections to the intermediate lumen section.
