    Abstract: An elongated catheter (41111) having an interior and an exterior surface, wherein the interior surface defines a lumen (81111) passing through the catheter. The catheter further including an enclosed cavity (451111) between the interior and exterior surfaces which encircles the lumen. The cavity having an inner wall and an outer wall, the outer wall being a resilient sleeve which can stretch generally independently of the inner wall. The cavity containing an amount of a suitable lubricating substance (381111) effective to permit the resilient sleeve to slide along an outer surface of the inner wall while in lubricated contact therewith when stretched independently of the inner wall, wherein the inner and the outer wall are joined together at distal end proximal ends of the enclosed cavity. An automated method for producing the same, including a series of automated dipping steps, is also disclosed. A ''Foley'' catheter having a balloon portion and a lubricated resilient sleeve, as disclosed above, is also disclosed, as are methods for manufacturing the same.

    Abstract: A cannula for insertion into a body cavity, duct, or vessel of a patient includes a parent cannula member 12 and an integral radiopaque tip 14. The tip 14 is configured so as to be distinguishable from internal body parts in an X ray or flouroscopic image, thus serving to precisely locate the position of the cannula within the patient without substantially obstructing the physician's view of such body parts. The cannula tip 14 and parent member 12 are separately pre-formed from a non-toxic polymeric material and can be constructed so as to have different hardnesses. In one embodiment, thetip is softer than the parent member in order to prevent internal injury to the patient, while in a second embodiment the tip is harder than the parent member for facilitating certain catheterization applications. The pre-formed tip and parent member are then dielectrically heated and welded securely together to form a unitary, integral cannula using a dielectric heating apparatus (not shown in Figure 1). The electrodes of the dielectric heating apparatus are connected to dies whose diametrical dimensions conform closely to those of the tip and parent member to provide the present cannula with completely smooth interior and exterior surfaces, In order to prevent the burning of the cannula during this heating process, air is vented from the junction area by providing the outer die with a convex interior surface and by forming longitudinal grooves in the external surface of the inner die or mandrel. The inner mandrel is formed by encapsulating the inner electrode with a highly insulative material to further inhibit burning of the cannula.

    Abstract: Articulation devices, systems, methods for articulation, and methods for fabricating articulation structures will often include simple balloon arrays, with inflation of the balloons interacting with elongate skeletal support structures so as to locally alter articulation of the skeleton. The balloons can be mounted to a substrate of the array, with the substrate having channels that can direct inflation fluid to a subset of the balloons. The articulation array structure may be formed using simple planar 3-D printing, extrusion, and/or micromachining techniques. The skeleton may comprise a simple helical coil, and the array can be used to locally deflect or elongate an axis of the coil under control of a processor. Inflation fluid may be directed to the balloons from an inflation fluid reservoir of an inflation system, with the inflation system preferably including valves controlled by the processor. The articulation structures can be employed in minimally invasive medical catheter systems, and also for industrial robotics, for supporting imaging systems, for entertainment and consumer products, and the like.
