A fourth lumen is provided for suctioning of saliva from just above the esophageal cuff.
More Information

No
The 510(k) summary describes a mechanical device (a tube with balloons) and makes no mention of AI, ML, image processing, or any software-driven analytical capabilities.

Yes
The device is used for "management of bleeding esophageal varices," which is a medical treatment.

No.

The device is described as a treatment device (naso-gastric double balloon tube) used in the management of bleeding esophageal varices. It does not mention any function related to diagnosing a condition.

No

The device description clearly details a physical tube with lumens, balloons, and other hardware components, indicating it is not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside the body.
  • Device Function: The Rüsch Blakemore Tube is a physical device inserted into the body (nasally or orally) to manage bleeding esophageal varices. It's a therapeutic device, not a diagnostic one that analyzes samples.
  • Intended Use: The intended use clearly states it's for the "management of bleeding esophageal varices," which is a treatment or intervention, not a diagnostic test.

Therefore, this device falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.
