    摘要: A multi-lumen catheter including a generally cylindrical body enclosing a first and second lumen separated by a generally planar septum. A first and second tip section extend from a distal end of the body. The first and second tip section may each include a generally planar surface. The second tip section may include a first segment extending from the distal end of the catheter body to a transition segment and a second segment extending from the transition segment to a distal end of the second tip section.

    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 tissue tunneler including an expandable attachment mechanism for securing a catheter. In one variation, the tissue tunneler comprises an elongate tunneler with a protrusion extending from the proximal end of the tunneler. An expansion mechanism is provided on the protrusion for insertion into the catheter. An oversleeve slidably disposed over the elongated tunneler may be provided to engage the expansion mechanism and trap the catheter between the oversleeve and the expansion mechanism. In another variation, the expansion mechanism may comprise of an expandable O-ring configured to engage an inner surface within a 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. In one variation, 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. In another variation, the valved catheter is a dual lumen catheter with a corresponding bifurcating extension for engaging the valves in the catheter in order to establish fluid communication through the catheter.

    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.
