摘要： Catheter devices with a tube management system are described. The catheter devices can have a catheter hub, a port extending from the catheter hub, a needle hub, a septum for controlling fluid flow from the port to a distal opening of the catheter hub, and a flexible tubing extending from the port. A tube deflector at the port guides the flexible tubing from a closed position to an open position. Tube securing mechanisms formed on the catheter hub also guides the flexible tubing from the closed position to the open position. A needle guard is usable with the needle device to block a tip of the needle.

摘要： A system for providing a continuous passage through a delivery catheter comprising a handle that defines an internal chamber. A first tube having a proximal end and a distal end and a first bore, the first tube being fixedly mounted within the handle, wherein the first bore at the distal end of the first tube is shaped to define a first inverse conical surface. A second tube having a proximal end and a distal end and a second bore, the second tube being slidably mounted within the handle, wherein the second bore is in axial alignment with the first bore. A third tube having a proximal end and a distal end and a third bore.

摘要： A multi-lumen catheter comprising a longitudinally extending elongated body portion, with at least two septa extending longitudinally through the entire body portion, and defining a central lumen and two side lumens. The central lumen is oblong shape in cross section and positioned between the side lumens. The septa forming the central lumen are configured to flex outwards when the central lumen is under pressure, whereby a cross sectional area of the central lumen resultantly increases to increase flow capacity through the central lumen. In some embodiments, the central lumen has a defining inner surface such that a radius of curvature of the central lumen inner surface is, in all locations, equal to or greater than a radius of curvature of an outer surface of a guide wire used for insertion of the multi-lumen catheter. The septa are each configured to fail under pressure before failure of the outer wall.

摘要： A single or multiple lumen catheter is disclosed which includes an expandable lumen. The expandable lumen is movable from a collapsed or sealed configuration to an open or expanded configuration. In the open configuration, the expandable lumen is dimensioned to receive a guidewire or stylet or facilitate the introduction of fluids into a patient.

摘要： A weeping balloon catheter includes a catheter having an elongate tubular body defining an inflation lumen and a combination lumen that terminates at an open distal end of the elongate tubular body. A dilation balloon is disposed at a distal end of the elongate tubular body and is in fluid communication with the inflation lumen. A drug delivery balloon is disposed at least partially over the dilation balloon and includes at least one drug release opening through an outer wall of the drug delivery balloon. The drug delivery balloon is in fluid communication with the combination lumen through a sidewall opening of the elongate tubular body.

摘要： A flexible expandable inter vivos tube includes at least one arched segmented portion, a corresponding movable element and at least one positioning mechanism. The at least one arched segmented portion and corresponding movable element forming a flexible closed longitudinally expandable tube. The at least one arched segment includes an H-shaped connector having at least one cavity that allows variable slidable movement of a free end portion of the corresponding movable element. A balloon is contained in each of the at least one cavity so that the hydraulic or air pressure within balloon expands the movable element and, thus, the circumference of the flexible inter vivos tube is increased.
