Esofag Kit 7 is a medical device used to treat esophageal strictures (narrowing of the esophagus). It consists of 7 dilators of increasing sizes that can be inserted into the esophagus to widen the stricture gradually. The kit is typically used under the guidance of a healthcare professional and may be done in a hospital or outpatient setting. The procedure may be performed with or without a local anesthetic or sedation. Esofag Kit 7 is a reusable device and should be properly sterilized after each use to ensure patient safety. It is important to follow the healthcare professional’s instructions and use the device only as directed.
