Abstract
A device for minimizing obstruction in a medical device that carries fluids includes a housing defining a channel configured to receive and secure a section of the medical device such that the section of the medical device extends coaxially with a central longitudinal axis of the channel. The device also includes components supported in the housing, including a motor, wherein the components are configured to be operated to impart motion to the housing and the attached medical device. The motion is configured to produce oscillatory motion of a frequency sufficient to concentrate shear stresses in a fluid boundary layer adjacent an inner wall of the medical device. The housing and the components supported in the housing are configured and arranged so that a device center of mass lies along or near the longitudinal axis of the channel.
