Abstract

To provide a lumen inspection apparatus.SOLUTION: A lumen inspection apparatus includes an elongate member and a sealing member at a distal end of the elongate member. The elongate member is inserted into a lumen of a medical instrument. The lumen inspection apparatus is translated along the lumen. The sealing member resiliently abut on a sidewall of the lumen as the lumen inspection apparatus is translated along the lumen of the medical instrument. A pressure source is activated to pressurize a region of the lumen adjacent to the sealing member. A fluid property of the lumen is monitored to detect whether the sealing member deforms in response to an obstruction in the lumen.SELECTED DRAWING: Figure 3A
