Introduction to RejuvenAir^®

9 million Americans struggle with the debilitating symptoms of COPD with Chronic Bronchitis.¹ The RejuvenAir System offers a unique solution that is aimed at treating the underlying cause of the disease; something no drug or device on the market does today.

The RejuvenAir System is a revolutionary cryosurgical device which applies a precise thermal dose or “metered cryospray” of extremely cold, -196°C liquid nitrogen to targeted areas within the lungs through a minimally invasive, often outpatient or same-day bronchoscopic procedure.

About COPD with Chronic Bronchitis

Chronic Bronchitis is the largest disease subset of Chronic Obstructive Pulmonary Disease (COPD).

Unlike common Bronchitis, which is acute and clears up quickly, Chronic Bronchitis (CB) is characterized by a long-term productive cough, breathlessness and/or wheezing as well as a tight chest sensation.

The persistent cough itself can be debilitating. Patients with Chronic Bronchitis often avoid social situations and give up activities, further contributing to a decline in overall well-being and quality of life. While current medications help alleviate symptoms, they don’t address the underlying cause of the disease and are largely ineffective.

How Metered Cryospray Works

In Chronic Bronchitis patients, the airways have been damaged. Cilia, the tiny hair-like cells lining the lungs that help move mucus and debris out of the airway, become dysfunctional, inducing an overabundance of goblet cells which over produce mucus. The combination of these factors contributes to inflammation, which makes it difficult to breathe.

The RejuvenAir System delivers small, metered doses of cryogen spray which flash freeze the surface area of damaged airways. Diseased cells are destroyed, leaving behind the extra-cellular structure that allows for new healthy cells, including cilia and mucus-producing goblet cells, to repopulate.

RejuvenAir rejuvenates the airways.

About Us

CSA Medical is committed to developing spray cryotherapy devices that improve the lives of people suffering from COPD with Chronic Bronchitis. We are advancing our core liquid nitrogen spray technology to target the underlying cause of Chronic Bronchitis – the over production of mucus and damaged cilia within the airways. By targeting and destroying these damaged cells without creating scar tissue, the body can begin the rapid regrowth of new, healthy normal functioning cells in the lung.

CSA Medical is currently conducting clinical studies with the RejuvenAir System. The clinical study aims to evaluate the effectiveness of the RejuvenAir System to reduce mucous production, cough, and inflammation in the Chronic Bronchitis patient population and to determine the extent of improvement in their overall health and quality of life.
