Abstract: An implant in accordance with an embodiment of the present technology includes proximal and distal end portions spaced apart from one another along a longitudinal axis and configured to be deployed at first and second airways, respectively, of a bronchial tree, the second airway being of a greater generation than the first airway. The implant includes a wire extending along a wire path within a tubular region coaxially aligned with the longitudinal axis. The wire includes first and second legs alternatingly disposed along the wire path and extending distally and proximally, respectively, in a circumferential direction about the longitudinal axis. The implant is configured to transition from a low-profile delivery state to an expanded deployed state at a treatment location and to allow mucociliary clearance from immediately distal to the implant to immediately proximal to the implant while the in deployed at the treatment location.

Abstract: Apparatus for quantitatively measuring respiratory air volume by summing measurements of the rib cage and abdomen dimensions. During a short calibration interval while the patient breathes normally, the summation coefficients for the rib cage and abdomen measurements are computed from samples of the two measurements taken simultaneously with samples of actual measured respiratory air volume.
