Conduits having distal cage structure for maintaining collateral channels in tissue and related methods
First Claim
1. A conduit comprising:
- a center section comprising a first end, a second end and a center-section passageway extending from said first end to said second end;
a plurality of first extension members extending from said first end, said first extension members being deflectable about said first end of said center section; and
a cage structure adjacent to said second end, said cage structure having at least one opening and at least one cage passageway in fluid communication with said center-section passageway.

Abstract
Devices and related methods are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, conduits maintain collateral openings or channels through the airway wall so that air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. The conduits include a center section with a passageway extending through the center section. The conduits further include a distal cage structure which has a passageway and at least one opening in fluid communication with the center section passageway. The medical kits disclosed herein are also directed to maintain collateral openings through airway walls.

37. A conduit having an undeployed state for facilitating delivery to a channel in a lung and a deployed state, different than the undeployed state, for maintaining the patency of the channel, said conduit comprising:
a radially expandable frame having a proximal section, a center section and a distal section, said proximal section comprising a plurality of proximal extension members, said center section comprising a first end at which said plurality of proximal extension members are attached, a second end, and a center-section passage extending from said first end to said second end, said distal section comprising a cage distal to said center section and said cage comprising at least one opening and at least one cage passage which is in fluid communication with said center-section passage wherein when said conduit is in said undeployed state, said proximal section, said center section and said distal section have a reduced profile, and when said conduit is in said deployed state, said plurality of extension members deflect outward forming a non-zero angle with an axis of said center-section passage, and said cage has an expanded profile greater than that of said cage when said conduit is in said undeployed state. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 53, 54, 55)
- 51. The conduit of clam 39 wherein said proximal extension members and said distal extension members, when said conduit is in said deployed state, are deflected from said axis of said center-section passage such that tissue may be compressed between opposing proximal and distal extension members when said conduit is deployed in a channel.

56. A conduit for maintaining the patency of a channel created in lung tissue, said conduit comprising:
-
a center section having a proximal end and a distal end and a center section passage within said center section extending between said ends;
a plurality of extension members comprising at least one proximal extension member and at least one distal extension member, said at least one proximal extension member having a fixed end attached to said proximal end of said center section and said at least one distal extension member having a fixed end attached to said distal end of said center section, each of said proximal and distal extension members having a free end being moveable such that said extension members may rotate about each of said ends of said center section to retain said tissue between said extension members; and
a cage adjacent to said distal end of said center section, said cage having at least one opening and a cage passage in fluid communication with said center section passage. - View Dependent Claims (57, 58)
