One-way valve devices for anchored implantation in a lung

摘要

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.

主权项

1. A device for obstructing an airway, the device comprising:
a central support structure, the central support structure having a proximal end and a distal end; an occluding member carried on the central support structure, the occluding member configured to transition between a compressed configuration and an occluding configuration; a first anchor having a first anchor end, the first anchor connected to the central support structure and configured to transition between a collapsed configuration and an expanded configuration; and a second anchor having a second anchor end, the second anchor configured to transition between a collapsed configuration and an expanded configuration; wherein the second anchor end is positioned distal to both the first anchor end and the distal end of the support structure when the first anchor and the second anchor are in the expanded configuration; and wherein the occluding member comprises a one-way valve.
