The description focuses on the mechanical aspects of a tissue sampling device and does not mention any computational or analytical capabilities that would suggest AI/ML.
No.
The device is used to obtain cells for diagnostic purposes (microscopic examination and/or microbiology cultures), not to treat a condition.
Yes.
The device is used to obtain endometrial cells for microscopic examination and/or for microbiology cultures, indicating its role in diagnosis.
No
The device description clearly describes a physical, sterile, single-use endometrial tissue sampling device with a shaft, brush head, and sheath, indicating it is a hardware medical device.
Based on the provided information, the MatrixBrush™ Endometrial Sampler is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens in vitro (outside the body) to provide information about a patient's health. This typically involves analyzing substances like blood, urine, or tissue samples in a laboratory setting.
- The MatrixBrush is a device used to obtain the sample (endometrial cells) from the patient's body. The subsequent examination of these cells (microscopic examination and/or microbiology cultures) is the in vitro part, but the device itself is the tool for collection.
Think of it this way: A blood collection tube is not an IVD, but the tests performed on the blood in the tube are IVDs. Similarly, the MatrixBrush collects the sample, and the analysis of that sample is where the IVD activity would occur.
The description clearly states its purpose is to "obtain endometrial cells" and describes the physical device used for this collection. It does not perform any diagnostic testing on the sample itself.

Device Description
The MatrixBrush Endometrial Sampler is a sterile, single-use endometrial tissue sampling device. The MatrixBrush shaft is comprised of a spirally twisted stainless steel core covered by plastic with marked gradations. A nylon brush head at the distal end of the device collects a tissue sample and an atraumatic plastic bulb located on the extreme distal end protects the patient from penetration. A moveable plastic sheath overlies the brush head and device shaft.

§ 884.1100 Endometrial brush.
(a)
Identification. An endometrial brush is a device designed to remove samples of the endometrium (the mucosal lining of the uterus) by brushing its surface. This device is used to study endometrial cytology (cells).(b)
Classification. Class II. The special controls for this device are:(1) FDA's:
(i) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Devices—Part I: Evaluation and Testing,’ ” and
(ii) “510(k) Sterility Review Guidance of 2/12/90 (K90-1),”
(2) Labeling:
(i) Indication: Only to evaluate the endometrium, and
(ii) Contraindications: Pregnancy, history of uterine perforation, or a recent cesarean section, and
(3) Design and testing:
(i) The sampling component is covered within the vagina, and
(ii) For adherence of the bristles and brush head.
