No
The device description and performance studies focus on mechanical properties and usability, with no mention of AI/ML algorithms or data processing.
Yes
The device is described as assisting in "tissue resection, exposure, and removal of tissue" and is designed to "provide retraction" within the stomach and colon, which are therapeutic actions.
No
The device is described as an Elastic Traction System used for retraction to assist in tissue resection, exposure, and removal of tissue during flexible endoscopy. Its function is to manipulate tissue for therapeutic purposes, not to diagnose a condition.
No
The device description clearly outlines physical components (Elastic Traction Device and Clipping Device) made of materials like silicone, and the performance studies focus on physical properties and interactions (dimension, release force, clamping strength, tensile strength, etc.), indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide retraction to assist in tissue resection, exposure, and removal of tissue within the stomach and colon during flexible endoscopy. This is a surgical/interventional procedure performed directly on the patient's body.
- Device Description: The device is a mechanical system consisting of clips and an elastic band used for physical manipulation of tissue.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. It does not analyze biological samples like blood, urine, or tissue biopsies in a laboratory setting.
IVD devices are used to perform tests on samples taken from the human body to provide information about a person's health. This device is used in vivo (within the body) to facilitate a medical procedure.

The logo has a simple, modern design.
The proposed device and the predicate device both used the two clips to anchor the edge of the tissue and lift the mucosal to provide the visualization with a connecting band during the ESD procedure. The main difference between the two devices is the material of the connecting band, the proposed device used the silicon rubber which provides retraction with elastic force of deforming, while the predicate device used the metal wire with restoring force of memory function.
