    摘要： A multi-lumen catheter defined by at least two separate tip sections distal to a dividing point includes strategic placement of openings in the tip sections to facilitate fluid flow and minimize typical problems associated with catheters. In a multi-lumen catheter having tip sections with a releasably joined or splittable region, the bond strength between the tip sections is varied along their length such that an increasing separation force is required to separate the tip sections from one another distal to the dividing point. Delivery of a multi-lumen catheter is improved with respect to both sheathed and non-sheathed delivery methods, in which a friction reducing structure is provided on either the catheter, delivery sheath or both to provide a buffer for a sheathed delivery and in which a unique guidewire aperture or additional lumen is provided in at least one of the tip sections for a non-sheathed delivery.

    摘要： A tissue tunneling device having a gripping mechanism for holding onto the body of the catheter. In one variation, the tissue tunneling device includes an elongate tunneler with a collet attached to the proximal end of the tunneler, and an oversleeve for providing compression to the collet to secure a distal or proximal portion of the catheter within the proximal end of the tunneling device. Internal ribs or surface profiles may be provided on an inner surface of the collet to prevent the catheter from moving when the collet is compressed onto the body of the catheter. The oversleeve may be configured such that over-sliding in the proximal direction is prevented. The collet may further be configured to receive the tips of a split-tip dialysis catheter.

    摘要： A valved catheter that allows placement and withdrawal of an accessing device or attachable unit without the risk of air embolism or blood loss. The valved catheter includes a catheter tube having a necked portion in its proximal end that forms an integral valve, the necked portion being surrounded by a compression sleeve that biases the valve in a closed position.

    摘要： A valved connector for controlling the flow of fluid having a valve assembly positioned within a connector housing having a first position wherein the valve assembly prevents fluid flow through the connector housing, and a second position wherein the valve assembly permits fluid flow through the connector housing. The valve assembly may be movable from the first position to the second position by a male luer fitting. The valve assembly is configured for multiple and repeated access and also for minimizing fluid flow restrictions. The valved connector may be designed for use with a catheter to provide for “over the guidewire” placement or replacement techniques with little or no bleed-back or air embolism.

    摘要： A hemostasis valve that is closed when not accessed, but which provides an unobstructed fluid pathway when accessed by a luer fitting/connector. An auto-closure valve within the hemostasis valve housing is flush with a top surface thereof, allowing easy cleaning (swabable) and maintenance when not accessed. When accessed with a connector or luer fitting, the valve opens completely, allowing an unobstructed high flow fluid path.
