Abstract
The lateral flow between adjacent lung segments is occluded by blocking collateral flow channels with particles. A gas flow is established from one lung segment through the flow channels in an intermediate fibrous septum, and out through the adjacent lung segment. Particles entrained in the gas flow become lodged in the collateral flow channels to eventually block flow.
Claims17
A method for occluding collateral flow channels between adjacent lung segments, said method comprising:
- providing a distribution of particles having a composition and a range of sizes from 100 μm to 1000 μm selected to lodge in and occlude the collateral flow channels;
- establishing a gas flow through the collateral flow channels in a wall between the at least two adjacent lung segments;
- and
- entraining the particles in said gas flow, wherein the particles lodge in the flow channels to occlude collateral flow.
