Summary for Patent: 11,197,965

Title:	Method and system for the administration of a pulmonary surfactant by atomization
Abstract:	The system allows optimizing the dispensing of aerosol medicaments. In particular the system allows the administration of an exogenous pulmonary surfactant to very young patients (e.g. preterm neonates). A catheter () conveys atomized surfactant directly to the retropharyngeal region in order to increase efficiency of the medicament administration without being invasive: this is particularly important for very young patients, such as pre-term born neonates suffering from neonatal Respiratory Distress Syndrome (nRDS). The catheter is made of biocompatible flexible material (e.g. plastic material). It is possible to couple the catheter with a rigid scaffolding (e.g. metallic) to increase stiffness of the device and to improve easiness of positioning operations. The delivery of the atomized medicament is done by means of an air blasting technique.
