Publication number: 20210193295Abstract: Apparatus, methods and computer-accessible medium can be provided for facilitating a treatment of at least one patient. For example, it is possible to utilize a data collection system to collect data of the patient(s), and a controller configured to authenticate access to a remote network, aggregate the collected patient data, store the aggregated patient data on a data storage device which is in communication with the remote network, and access a service module which is in communication with the remote network. An electromagnetic radiation (“EMR”) source can be provided that is configured to generate an EMR beam;. The EMR-based treatment system can comprise a focus optic configured to converge the EMR beam to a focal region located along an optical axis, and a window located a predetermined depth away from the focal region between the focal region and the focus optic along the optical axis. The window can be configured to transmit the EMR beam, and contact a surface of the tissue.Type: ApplicationFiled: December 18, 2020Publication date: June 24, 2021Inventors: JAYANT BHAWALKAR, LEWIS J.
