Adjustable endobronchial valve

Abstract

A bronchial flow control device comprises a tubular body comprising struts extending between first and second ends, the struts being expandable between radially contracted and expanded shapes, a valve disposed proximate the second end, a membrane covering the struts, and microfibers on the membrane. A method comprises attaching a bronchial valve to a delivery catheter in an unexpanded state, inserting the bronchial valve into an airway, actuating the delivery catheter to radially expand the bronchial valve, pushing microfibers into an anatomic duct wall, detaching the delivery catheter from the bronchial valve, and withdrawing the delivery catheter from the airway. A delivery system for a valve comprises a handle, a first actuator to control a rotational position of a first coupler, a second actuator to control a radial position of a second coupler, and a third actuator to control an axial position between the first and second couplers.
