Title: Cleaning System for Medical Imaging Device
Inventors: Lawrence J. Gerrans, Erhan H. Gunday
Abstract: An imaging catheter device includes a catheter body with a proximal end, a distal end, and a lumen; a cleaning member disposed at the distal end; and an imaging device movably disposed in the lumen and through the cleaning member; wherein the cleaning member includes a conduit through which the imaging device moves and a flexible material at least partially occluding the conduit such that the imaging device displaces at least some of the flexible material when moved through the conduit. A method of cleaning an imaging catheter device includes disposing a cleaning member including a conduit and a flexible material at least partially occluding the conduit at a distal end of a catheter lumen; positioning an imaging device in the catheter lumen; and cleaning the imaging device by moving it through the conduit such that it displaces at least some of the flexible material.
