PENCIL-GRIP FNA SYRINGE HOLDER AND EFFORTLESS NEEDLE REMOVER by TAO & TAO TECHNOLOGYT, INC.

The TAO ASPIRATORTM is a device to hold a 10cc syringe for performing fine needle aspiration of a palpable mass with one hand, while stabilizing the mass to be aspirated with the other hand. It is equipped with a release button for automatically drawing back the syringe plunger, and is designed to be held in a pencil-grip manner. This device places the hand relatively close to the needle tip while the hand is in a position of natural function, enabling the needle movement using fine motor control of the hand.

The PLASTIC FINGERTM is an accessory to the TAO ASPIRATORTM to facilitate specimen procurement. It facilitates needle removal so that air can be drawn into the syringe, and the aspirated material in the needle and needle hub can then be expressed onto slides. It can also be used to grip slides for fixation and staining.

Device Description

AI/ML Overview

The provided text is a 510(k) premarket notification letter from the FDA for the TAO ASPIRATOR™ and PLASTIC FINGER™. This document confirms the substantial equivalence of the devices to legally marketed predicates and outlines their indications for use.

Crucially, the document does not contain any information regarding acceptance criteria or a study proving that the device meets those criteria.

The 510(k) clearance process focuses on substantial equivalence, meaning the new device is as safe and effective as a legally marketed predicate device. While a manufacturer would typically have internal testing and validation data to support their 510(k) submission, this specific FDA letter does not describe or summarize those studies or their acceptance criteria.

Therefore, I cannot provide the requested information based on the given input. The categories in your request (acceptance criteria table, sample sizes, ground truth establishment, MRMC studies, standalone performance, etc.) are all relevant to study design and results, which are not present in this regulatory correspondence.

Dear Ms. Tao:

We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined the devices are substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the devices, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your devices are classified (see above) into either class II (Special Controls) or class III (Premarket Approval), they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements , as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. In addition, FDA may publish further announcements concerning your devices in the Federal Register. Please note: this response to your premarket notification submissions does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
