    摘要: Medical devices and related methods enable physicians and/or other medical personnel to access percutaneously the interior of a patient. One particular device includes a housing which defines a cavity, a first opening into the cavity, and a second opening into the cavity. The housing is implantable in a patient. The cavity is placed subcutaneously within the patient. The first opening is substantially flush with the surface of the skin of the patient and creates a percutaneous passageway from the exterior of the skin of the patient into the cavity, and the second opening creates a passageway from the cavity into the interior of the patient. A connector is coupled to the second opening and disposed substantially within the cavity to enable a connection between a first device and a second device disposed within the interior of the patient.

    摘要: A pressure activated two-way slit valve assembly is designed to be used in combination with, but not limited to, a high flow rate catheter to prevent accidental ingestion of air or loss of blood if the closure cap comes off during non-use of the catheter. In addition, the potential for occlusion of the catheter due to blood clots in the catheter and catheter related infection is substantially reduced. The pressure activated two-way slit valve assembly includes a first end, a second end, a wall defining a dumbbell shaped channel, and a flexible, thin disk having a slit and positioned within the pressure activated two-way slit valve assembly to reside within the dumbbell shaped channel. The slit and the dumbbell shaped channel are sized to enable the slit to deform in response to a predetermined pressure differential across the slit to allow fluid to pass therethrough.
