    摘要： A self-flushing connector includes a housing having a cavity, a first inlet port, a second inlet port, and an outlet port. A collapsible valve is disposed within the cavity. A first flow path extends from the first inlet port to the outlet port. The first inlet port and the second inlet port are fluidly connected through a gap defined between the body of the collapsible valve and an inner wall of the housing defining the cavity. A second flow path extends from the second inlet port to the first flow path. When the collapsible valve is in a closed state, the collapsible valve fluidly disconnects the second flow path from the first flow path while allowing fluid to flow through the first flow path. When the collapsible valve is in an open state, the second flow path is fluidly connected to the first flow path.

    摘要： A medical connector for use in a fluid pathway. A valve member with sealing rings helps preclude undesired accumulation of fluid within the connector. A branched connector includes a fluid diverter extending away from a port of the branched connector. The fluid diverter is configured to divert fluid flowing through the branched connector and into a medical connector attached thereto, flushing a distal portion of the medical connector.

    摘要： The disclosed subject matter relates to a valve device that includes a valve member located within a housing in which the valve member's operation can be bypassed. For example, the valve device can include a bypass device that has an input structure, a motion conversion structure, and an output structure. The input structure can include a portion configured to resiliently deform if a valve opening input force is applied to the input structure in an input direction. The motion conversion structure can be configured to convert the valve opening input force into motion of the output structure in an output direction that is non-parallel to the input direction. The output structure can be configured to move the valve member (e.g., from a closed state to an opened state in order to bypass normal valve operation) if the motion conversion structure is displaced in the input direction. The valve device can be used in various manners, and is particularly suitable for use in a patient fluid delivery system.

    摘要： Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imageable portions (e.g., portions which are visible under magnetic resonance imaging (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked.
