Cleaning of body-inserted medical tubes
First Claim
1. A mechanically-actuated cleaning device for removing biofilm or debris from a body-inserted medical tube, comprising:
- an elongate body comprising a distal end, a proximal end and an inner lumen extending from the proximal end to the distal end,a cleaning member positioned at or near the distal end of the elongate body, wherein the cleaning member is mechanically actuated,wherein the cleaning member is selectively movable between a radially-collapsed configuration and a radially-expanded configuration,wherein at least a portion of the cleaning member is configured to circumferentially contact an interior surface of a medical tube when in the radially-expanded configuration,wherein the cleaning member, when in the radially-expanded configuration, is configured to remove biofilm or debris from the medical tube as the elongate body is withdrawn from the medical tube,wherein the cleaning member, when in the radially-expanded configuration, comprises a rounded profile,wherein the portion of the cleaning member that is configured to circumferentially contact the interior surface of the medical tube comprises a generally smooth contact surface; and
a mechanically-actuated control assembly coupled to the proximal end of the elongate body,wherein the cleaning member is selectively movable between the radially-collapsed configuration and the radially-expanded configuration by mechanical manipulation of the control assembly.

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 method for cleaning endotracheal tubes comprises inserting a cleaning device within an endotracheal tube while a cleaning member is in a compressed position, radially expanding the cleaning member to an expanded position within the endotracheal tube, and withdrawing the cleaning device from the endotracheal tube with the cleaning member in the expanded position.

9. A mechanically-actuated cleaning device for removing biofilm or debris from a body-inserted medical tube, comprising:
-
an elongate body comprising a distal end and a proximal end, a cleaning member positioned at or near the distal end of the elongate body, wherein the cleaning member is selectively movable between a collapsed configuration and an expanded configuration, wherein at least a portion of the cleaning member is configured to contact an interior surface of a medical tube when the cleaning member is in the expanded configuration, wherein the cleaning member, when in the expanded configuration, is configured to remove biofilm or debris from the interior surface of the medical tube as the elongate body is withdrawn from the medical tube, wherein the cleaning member, when in the expanded configuration, comprises a rounded profile, wherein the portion of the cleaning member that is configured to contact the interior surface of the medical tube is non-porous; and a mechanically-actuated actuation assembly coupled to the proximal end of the elongate body, wherein the actuation assembly is configured to selectively move the cleaning member between the collapsed configuration and the expanded configuration by mechanical manipulation of the actuation assembly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
