Articulable anchor
First Claim
1. An implantable device configured to be secured within an air passageway, the device comprising:
- a distal portion comprising an anchor system and a longitudinal axis, the anchor system comprising at least one piercing tip and being configured to engage tissue of an air passageway wall;
a proximal portion; and
a flexible portion connecting the distal portion to the proximal portion, the flexible portion being configured such that the distal portion can articulate substantially with respect to the proximal portion such that the distal portion and the proximal portion are non-collinear along the longitudinal axis of the distal portion.

Abstract
Embodiments disclosed herein relate to devices implantable into a human lung, for example to reduce the volume of air trapped in a diseased portion of the lung to prevent inhalation while permitting expiration out of the diseased portion. In some embodiments, the device comprises a distal portion with an anchor system that may anchor the device into tissue of an air passageway wall, and the distal portion may be connected to a proximal portion via a flexible portion that permits the distal portion to articulate substantially with respect to the proximal portion, such that the distal portion and the proximal portion may be non-collinear along a longitudinal axis of the distal portion. This may facilitate implantation of the device into a non-linear air passageway.

20. A system for inserting a pulmonary device into an air passageway of a lung, the system comprising:
-
a catheter; and a pulmonary device configured to be inserted into a distal end of the catheter, the pulmonary device comprising; a proximal portion; a distal portion comprising a longitudinal axis and at least one anchor configured to secure the pulmonary device within the air passageway, and a connecting member coupling the proximal portion and the distal portion and allowing the longitudinal axis of the distal portion to be non-collinear with the proximal portion. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
