Title:
VALVED DEVICES, TREATMENTS AND METHODS TO RESTORE TISSUE ELASTIC RECOIL
Document Type and Number:
WIPO Patent Application WO/2022/221691
Kind Code:
A9
Abstract:
In some instances, it is desired to restrict or block airflow to a region of the lung such as to replicate the effects of lung volume reduction surgery. This may be achieved with the use of a pulmonary treatment valve that is implanted minimally invasively without the need for surgery. In some instances, such a valve allows air to flow out of the lobe through the valve when the patient exhales but blocks air from entering the lob during inhalation. This facilitates emptying the lobe of air over time. This has been shown to be beneficial in the treatment of a population of patients suffering from emphysema. In other instances, the airflow is reduced or restricted rather than blocked. And in still other instances, the airflow is restricted upon exhalation and blocked upon inhalation.
