Clinical Trial Summary

This is a Post-Market Evaluation of the Zephyr Valve 5.5-LP EBV to assess Treated Lobar Volume Reduction (TLVR), changes in lung function and the safety profile of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.

Description:

This is a multi-center, single-arm, prospective, observational study. Approximately 70 study participants undergoing Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV will be enrolled and followed out to 3 months. Assessments will be conducted at 45 days and 3 months. The evaluation will be conducted at up to 6 sites. Patients prescribed Zephyr Valve treatment for their emphysema will be consented and will be enrolled only after: 1) determination of little to no collateral ventilation between target and ipsilateral lobes and 2) implantation of at least one Zephyr Valve 5.5-LP EBV. Baseline data will be collected retrospectively after enrollment of a patient in the Post-Market Evaluation. Performance and safety of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP will be evaluated post-treatment based on data collected until 3 months after the treatment.

Eligibility

Inclusion Criteria:

• Patients with severe emphysema prescribed treatment with Zephyr Valves
• Zephyr Valve Treatment with the use of at least one Zephyr Valve 5.5-LP EBV

Exclusion Criteria:

• Patients determined to have collateral ventilation between the target(s) and ipsilateral lobe(s).

Related Conditions & MeSH terms

• Emphysema
• Pulmonary Emphysema

Intervention

Device:
• The Pulmonx Zephyr Endobronchial Valve (EBV) 5.5- LP
The Zephyr Valves are implantable bronchial valves intended to control airflow in order to improve lung function in patients with hyperinflation associated with severe emphysema and/or to reduce air leaks.
