    摘要： A split tip dialysis catheter having an outer tube and an inner tube, the two tubes which can be arranged over at least a portion of their length in a coaxial configuration. The inner tube may be connected to the outer tube at a proximal bifurcation, secured at a distal end of the outer tube or both, but generally the inner tube will remain free to move relative to the outer tube to optimize functionality. In addition, the inner tube can be arranged to be removable from the catheter for replacement thereof.

    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 system for effecting fluid-tight coupling and mechanical joinder between a medical device and a catheter tube. An elongated catheter connection stem attached to the medical device is received in the lumen of the catheter. A catheter securement collar is advanced proximally along the exterior of the catheter and connection stem inside the catheter into the assembled condition of the connection system, passing a locking ring on the interior of the securement collar over an enlargement on the distal end of the connection stem. Maximum catheter compression occurs at the locking ring, while a void internal of the catheter system is filled with an enlarged securement lip of catheter material. Distal of maximum catheter wall compression, the catheter traverses a tortuous path between the locking ring and the enlargement, around the shoulder of the enlargement, and along the adjacent surface of the enlargement.

    摘要： Methods of coupling a catheter to a stem are disclosed. In some embodiments, a stem extends longitudinally between a proximal end and a distal end, and the stem can include at least one enlargement positioned between the proximal end and the distal end. In some embodiments, a catheter can be positioned over the at least one enlargement and over a region of the stem that is proximal to the at least one enlargement. In further embodiments, a collar can be mated to the stem.

    摘要： A multifunction adaptor for an open-ended catheter that allows placement of the catheter while minimizing the risk of air embolism or blood loss through the open (proximal) end of the catheter body. In one variation, the design allows passage of a standard guidewire for “over-the-guidewire” placement techniques and a connection for catheter flushing using a standard syringe. In another variation, the multifunction adaptor is configured for coupling a tunneler to the proximal end of a catheter.
