Abstract

A lung constriction device and method provide lung air leak suppression or lung volume reduction. The lung constriction device includes a jacket of flexible material. The jacket is configured to cover at least a portion of a lung. The jacket is further configured to receive the lung portion as it is drawn therein. The jacket may be expandable and held in an expanded condition as the lung tissue is drawn into the jacket. Thereafter, the jacket is permitted to collapse about the lung portion to constrict the lung portion. The jacket may alternatively be nonexpandable. As the lung tissue is drawn into the jacket, it will collapse. Once disposed in the jacket, the jacket constricts the lung tissue to provide leakage suppression or lung volume reduction. The jacket may further be severable so that after the lung portion is drawn into the jacket, the jacket may be severed to section the lung portion.
