1. A medical tube cleaning device, comprising:
- an elongated member having a proximal end and a distal end, said elongated member comprising at least one lumen extending within an interior of said elongated member along at least a portion of a length of said elongated member;
an expansion member positioned along the elongated member, said expansion member being adapted to selectively move between a radially-collapsed position and a radially-expanded position;
an outer sleeve positioned along an exterior surface of, and at least partially along a longitudinal length of, the expansion member, wherein the outer sleeve is configured to form a removal member to engage an interior surface of a medical tube when the expansion member is in the radially-expanded position;
wherein the removal member is configured to apply radial pressure to the interior surface of the medical tube with a pressure sufficient to remove biofilm without causing invagination of said biofilm;
wherein said removal member formed by the outer sleeve is configured to contact and remove debris collected on an interior surface of the medical tube when said cleaning device is moved relative to the medical tube;
an actuation assembly coupled to the proximal end of the elongated member;
wherein the at least one interior lumen is configured to receive a visualization scope;
wherein the expansion member is configured to move between the radially-collapsed position and the radially-expanded position by manipulation of the actuation assembly; and
wherein expansion and collapse of the expansion member occurs mechanically.

Abstract
Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a mechanically-actuated endotracheal tube cleaning device is configured to removably receive a visualization member to provide cleaning of the endotracheal tube under direct visualization.

16. A cleaning device for cleaning a medical tube, comprising:
-
an elongated member having a proximal end and a distal end, said elongated member comprising at least one lumen extending within an interior of said elongated member along at least a portion of a length of said elongated member; an expandable structure positioned along the elongated member, said expandable structure being adapted to selectively move between a radially-collapsed position and a radially-expanded position; an outer sleeve positioned along an outer surface of the expandable structure, wherein the outer sleeve is configured to form a removal member to engage an interior surface of a medical tube when the expandable structure is in the radially-expanded position; wherein at least a portion of the outer sleeve is configured to radially expand together with the expandable structure when the expandable structure moves from the radially-collapsed position to the radially-expanded position; wherein the removal member is configured to apply a radial pressure to the interior surface of the medical tube in order to remove biofilm; wherein said removal member formed by the outer sleeve is configured to contact and remove debris collected on an interior surface of the medical tube when said cleaning device is moved relative to the medical tube; and an actuation assembly coupled to the proximal end of the elongated member; wherein the expandable structure is configured to move between the radially-collapsed position and the radially-expanded position by manipulation of the actuation assembly; and wherein expansion and collapse of the expandable structure occurs mechanically. - View Dependent Claims (17, 18, 19, 20)
