The document discusses a dual-function camera-cytology device designed for gastrointestinal diagnosis, particularly esophageal cancer, which is projected to become prevalent by 2030. It features a pill-sized capsule with a retractable balloon for sampling and visualizing the esophagus, intending to improve detection rates and reduce the need for invasive procedures. Prototypes are being developed, and the device aims to be portable and usable by non-professionals without sedation, while the intellectual property is secured under a pending patent.
