The device description and performance studies focus on the mechanical function of a biopsy needle and do not mention any AI/ML components or capabilities.
No.
The device is a biopsy sampling needle used to collect tissue samples for diagnostic purposes, not to treat or alleviate a medical condition.
No
The device is a needle used for biopsy sampling, which is a method of obtaining tissue for diagnostic purposes, but the device itself does not perform the diagnosis.
No
The device description clearly outlines physical components (needle head, PEEK outer tube assembly, handle) and describes a physical procedure for use, indicating it is a hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
- Device Function: This device is a biopsy sampling needle used to collect tissue samples from within the body (tracheobronchial tree or gastrointestinal tract) during an endoscopic procedure.
- Purpose: Its purpose is to obtain a physical sample of tissue, not to perform a diagnostic test on a specimen outside the body. The diagnostic testing would be performed on the sample collected by this device, likely in a laboratory setting using IVD methods.
Therefore, this device is a surgical/endoscopic instrument used for tissue collection, not an IVD.

Device Description
Sterile endoscope biopsy sampling needle, Model: DT-EN-W7 is mainly composed of needle head, PEEK outer tube assembly, and handle. Sizes are available in 18 - 22 gauge needles. The length of the needles range is between 0 and 80 mm. The needle is used by advancing the entire device to the site of soft tissue sampling through endoscopic channel aperture. The needle is advanced with gentle but firm pressure. Once the needle is in position, stab hard into the tissue and connect the external end of needle tube with aspirator in negative pressure. Retreat the needle head into tube, and get the needle out of the endoscope through the channel. The sample can then be expelled from the stylet notch.
