Abstract: A composite thermoset polymer matrix structure having a plurality of homogeneously bonded thermoset polymer layers and a method of forming the same is disclosed. Each of the layers is formed from either a pure thermoset polymer resin or a composition of any of a variety of thermoset polymer resins and any of a variety of agents or combination of agents heterogeneously dispersed and suspended within the thermoset polymer resin. In this manner, each layer exhibits a distinct desirable functional property or characteristic depending upon an intended application. The agents are selected from a group of additives including but not limited to anti-microbial agents, anti-fungal agents, anti-viral agents, anti-thrombotic agents, friction reducing agents; radiopaque agents, and electrically conductive or resistive agents. The composite thermoset polymer matrix structure may be formed into any size or any shape, object, or structure.

Abstract: A flexible tubing includes a wall provided with a plurality of braided elements forming a braid within the wall of the tube. The braided elements include one or more signal transmitting elements and one or more metallic or non-metallic structural elements having structural properties different from the signal transmitting elements. The signal transmitting elements may be conductive wires, e.g., a sensor conductor or thermocouple, or optical fibers. Additionally, a combination of conductive wires and optical fibers may be provided within the braid. The structural elements preferably provide a degree of torsional stiffness, kink resistance, or luminal rigidity to the catheter which is different than would otherwise be provided solely with one or more signal transmitting elements. The tubing wall is preferably a cross-linking polymer, such as polyimide matrix. In manufacture of the tubing, one or more layers of the polymer are coated on a mandrel and permitted to cure to form an inner layer of the tubing.
