Abstract
An implantable device for control over the size of emphysematous bullae in a lung, including: an elongated central region having a fixed axial length; a first end including a first anchor; and a second end including a second anchor.
Claims19
A method of delivering an implantable device to a target site in a lung of a patient, the implantable device comprising:
- (a) an elongated central body having a fixed axial length such that the elongated central body rigidly extends along a longitudinal axis;
- (b) a distal end including a first anchor;
- and
- (c) a proximal end including a second anchor;
- the method comprising the steps of:
- (a) aligning the first anchor to the target site while the implantable device is at least partially placed within a deployment device;
- (b) deploying the first anchor by flexibly deforming the first anchor outwardly relative to the longitudinal axis such that the first anchor engages a first region of the target site of the lung;
- (c) pulling the first anchor in a proximal direction towards the second anchor to reduce the volume of the lung;
- and
- (d) severing an engagement feature, untying the engagement feature, or disconnecting magnets of the engagement feature to flexibly deform the second anchor outwardly relative to the longitudinal axis from a first position to a second position such that the second anchor engages a second region of the target site of the lung, wherein the second position is distal to the first position.

A method of delivering an implantable device into a target site of a lung of a patient, comprising the steps of:
- (a) guiding a delivery device to the target site within the lung, and wherein a lumen of the delivery device contains an implantable device compressed within a distal end of the delivery device, the implantable device comprising:
- (i) an elongated central body having a fixed axial length such that the elongated central body rigidly extends along a longitudinal axis;
- (ii) a distal end including a distal expandable anchor;
- and
- (iii) a proximal end including a proximal expandable anchor;
- (b) releasing the distal end of the implantable device from the delivery device by selectively transitioning the distal expandable anchor outwardly relative to the longitudinal axis to expand the distal expandable anchor within the target site;
- (c) pulling the implantable device proximally, wherein the pulling causes the distal expandable anchor to pull tissue at the target site proximally;
- (d) selectively transitioning the proximal expandable anchor outwardly relative to the longitudinal axis to expand the proximal expandable anchor within the target site;
- and
- (e) releasing the implantable device from the delivery device by severing an engagement feature, untying the engagement feature, or disconnecting magnets of the engagement feature.
