One-way valve devices for anchored implantation in a lung
First Claim
1. An intra-bronchial device for placement in an air passageway of a patient, the device comprising:
- a support structure comprising a plurality of support members extending from an attachment portion and terminating at free ends;
a flexible and air-impermeable membrane carried by the support structure; and
at least one anchor carried by the support structure that is configured to anchor the intra-bronchial device within the air passageway when the anchor is deployed;
wherein the device is configured to permit air to flow in a first direction while preventing air flow past the device in a second direction that is opposite to the first direction.

Abstract
An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.

13. An intra-bronchial device comprising:
-
a support structure comprising a plurality of support members extending in a curvilinear manner from an attachment;
a flexible membrane carried by the support structure to form a substantially umbrella-shaped structure configured to be implanted in an air passageway to prevent air from flowing in a first direction past the device, while allowing fluid to travel past the obstructing member in an opposite direction. - View Dependent Claims (14, 15, 16, 17)
