1. An implant configured for maintaining an artificial opening in a wall of an airway, the implant comprising:
- a support member having a proximal portion, a mid portion, a distal portion, and an interior passage extending therethrough, where the proximal, and distal portions are all expandable and the proximal and distal portions are expandable to a greater size than the mid portion, where the mid portion includes a plurality of members forming a mesh having a plurality of interstices and wherein the proximal and distal portions are expandable such that the support member forms a grommet shape and secures the support member about a perimeter of the artificial opening in the airway wall; and
a means for maintaining patency of the artificial opening in the airway wall at 12 weeks following deployment of the implant in the artificial opening in the airway wall.

30. An implant configured for maintaining an artificial opening in a wall of an airway, the implant comprising:
-
a support member having a proximal portion, a mid portion, a distal portion, and an interior passage extending therethrough, where the proximal, and distal portions are all expandable and the proximal and distal portions are expandable to a greater size than the mid portion, such that the support member forms a grommet shape and secures the support member about a perimeter of the artificial opening in the airway wall; and a composition located on the support member, where the composition comprises approximately 400 micrograms of paclitaxel. - View Dependent Claims (31, 32)
