Abstract: A tubular medical device is adapted for placement into a human patient or other living being. The tubular medical device includes a body member and a rib structure. The body member extends along a longitudinal axis and has an outer surface and an inner surface. The inner surface defines a hole extending Longitudinally through the body member between opposite ends thereof. The rib structure is connected to the outer surface of the body member and projects outwardly from the outer surface relative to the longitudinal axis. The rib structure and the outer surface of the body member define at least one channel oriented transversely to the longitudinal axis. The tubular medical device can be constructed in a variety of embodiments including a tympanostomy tube device, a ribbed sleeve and an elongated tube.
