Bronchial flow control devices and methods of use
First Claim
1. A flow control device for a bronchial passageway, comprising:
- a valve member that regulates fluid flow through the flow control device;
a seal member that at least partially surrounds the valve member, wherein the seal member extends radially outward and forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway;
an anchor member secured to the seal member, wherein the anchor member exerts a radial force against the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway and retains the flow control device in a fixed location in the bronchial passageway; and
a valve protector that at least partially surrounds the valve member, the valve protector having sufficient rigidity to maintain the shape of the valve member against compression;
wherein the seal member includes a first flange that at least partially surrounds an outer perimeter of the flow control device and that extends radially outward a first distance with respect to a longitudinal axis of the flow control device.

Abstract
Disclosed are methods and devices for regulating fluid flow to and from a region of a patient'"'"'s lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. An identified region of the lung is targeted for treatment, such as to modify the flow to the targeted lung region or to achieve volume reduction or collapse of the targeted lung region. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. The bronchial isolation of the targeted lung region is accomplished by implanting a flow control device into a bronchial passageway that feeds air to a targeted lung region.

5. A flow control device for a bronchial passageway, comprising:
-
a valve member that regulates fluid flow through the flow control device;
a seal member that at least partially surrounds the valve member, wherein the seal member extends radially outward and forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway;
an anchor member secured to the seal member, wherein the anchor member exerts a radial force against the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway and retains the flow control device in a fixed location in the bronchial passageway; and
a valve protector that at least partially surrounds the valve member, the valve protector having sufficient rigidity to maintain the shape of the valve member against compression, wherein the seal member includes a cuff that defines a cavity, and wherein the cuff forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway and retains the flow control device in a fixed location in the bronchial passageway. - View Dependent Claims (6, 7, 8, 9)
