Abstract
A reinforced catheter or sheath includes an inner tube manufactured via an extrusion process from a mixture of thermoplastic and hollow glass beads. The resultant tube exhibits an inner goose bump surface that defines a central lumen. A reinforcement, such as a braid and/or coil is attached to at least a segment of the outer surface of the inner tube. A second tube of thermoplastic is extruded over at least a portion of the reinforcement. The inner goose bump surface exhibits a net low coefficient of friction comparable to that of polytetrafluoroethylene (PTFE).
