Abstract
Methods and assemblies for reducing the volume of a lung. A plurality of anchors are anchored at different positions in the lung. A cord is attached to each of the anchors. The anchors are drawn towards one another via the cords to cause the lung to collapse, thus compressing the tissue in the lung and establishing a reduction in lung volume.
Claims72
A lung volume reduction device comprising:
- a) at least one anchor having a reduced profile and being configured to assume an expanded profile wherein in said reduced profile said anchor is capable of being advanced into an airway of the lung and in said expanded profile said anchor secures to lung tissue;
- b) at least one connector;
- c) at least one cord having a proximal end and a distal end, said proximal end being attached to at least one of said connectors which is adapted to be self-locking about said cord and said distal end being attached to at least one of said anchors;
- and
- d) a delivery device being configured to removably seat at least one of said anchors on a distal end.
An anchor for use with a lung volume reduction device having a connector joining said anchor to a second anchor, wherein said anchor comprises:
- a central portion and an attachment portion connected to said central portion, said attachment portion being moveable between a reduced profile and an expanded profile, wherein when in said reduced profile said anchor is capable of being advanced into a passageway of the lung and when in said expanded profile said attachment portion attaches to lung tissue;
- and
- at least one cord having a distal end and a proximal end, said distal end being attached to said central portion of said anchor and said proximal end secured to the connector which is adapted to be self-locking about said cord.
A delivery device for use with a lung volume reduction device, wherein said delivery device comprises:
- an elongate member having a distal and a proximal end, said elongate member being adapted to be advanced within airways of at least one lung, said elongated member being configured to removably seat the anchor on a distal end of the elongated member wherein said lung volume reduction device has at least one cord having a proximal end and a distal end, the distal end of the cord being attached to said anchor and the proximal end of the cord being attached to at least one connector which is adapted to be self-locking bout said cord.
A method for minimally invasively or non-invasively treating a lung having at least an emphysematous portion comprising the step of improving a pulmonary function of at least a first portion of the lung by reducing a volume of a second portion of the lung while maintaining communication between the first portion and the second portion.
