No
The device description details a purely mechanical tool for measuring esophagus size. There is no mention of software, algorithms, or data processing that would indicate the presence of AI/ML.
No
The device is described as a "laparoscopic accessory used to estimate the appropriate size LINX® device," indicating its function is for measurement and sizing during a surgical procedure, not for treating a medical condition itself.
No
Explanation: The device is described as an "accessory" and a "laparoscopic instrument" used to "estimate the appropriate size LINX® device" by measuring the esophagus. It does not diagnose a medical condition or disease.
No
The device description clearly states it is a "single use disposable device" and a "laparoscopic instrument" with physical components like a "handset," "shaft," "circular curved tip," "thumbwheel," and "magnets." This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The ETHICON Linx Esophagus Sizing Tool is a surgical accessory used during a laparoscopic procedure to physically measure the size of the esophagus. It does not analyze any biological samples or provide diagnostic information based on those samples.
- Intended Use: The intended use is to "estimate the appropriate size LINX® device," which is a physical implant. This is a measurement and sizing function, not a diagnostic one.
- Device Description: The description details a physical tool with a measuring mechanism, not a system for analyzing biological samples.
Therefore, the device falls under the category of a surgical instrument or accessory, not an In Vitro Diagnostic.

Device Description
The ETHICON Linx Esophagus Sizing Tool (also referred to as LINX® Esophagus Sizing Tool, hereafter) is an accessory to the LINX Reflux Management System implant (packaged separately). The LINX Esophagus Sizing Tool is a single use disposable device that is provided sterile. The LINX Esophagus Sizing Tool is a laparoscopic instrument and has two ends – the handset, considered the proximal end and not intended for patient contact, and the shaft with protruding circular curved tip, considered the distal end and is intended for limited contact with the patient. The handset is designed with a thumbwheel for one-handed operation. When actuated, the thumbwheel advances and retracts the soft polymeric circular curved tip of the distal end. The handle has a numerical indicator which directly correlates with the number of beads for the range of sizes of the approved LINX implant device. The shaft and distal end of the circular curved tip each have a magnet which allows the user to create a loop and attach the magnets to each other. Once the magnets are attached, the user retracts slack from the soft distal end until the loop is in circumferential contact with the esophagus. The LINX Esophagus Sizing Tool is utilized at the time of implant to associate the esophagus size to a LINX implant device size to aid in guiding the user into choosing an appropriately sized LINX implant device.

Technological Characteristics
The design and performance of the LINX Esophagus Sizing Tool is based on the currently marketed predicate device. The changes described in this submission do not affect the intended use of the device or alter the fundamental scientific technology of the device. The clinical, technical and biological parameters of the subject device are the same as the predicate. The technique used for determining the appropriate LINX implant device size remains unchanged between the subject and predicate designs. The subject and predicate devices are both manually powered and not powered by an outside energy source. Neither the subject device nor predicate device uses software. The modifications to the design were made to enhance comfortability and ease of use of the subject device.
The primary differences in the devices include design and operation of the handle and shaft stiffness. The 510(k)-subject device was designed for one-handed operation, while the predicate requires two hands. Control for extending and retracting the distal loop of the 510(k)-subject device is accomplished with the use of a thumbwheel; the predicate device requires the user to depress the end of the handle to extend the distal loop; retraction occurs by actuating a sidemounted lever. The sizing indicator on the handle of the 510(k)-subject device is different from the predicate - the subject device's numerical indicator displays 13-18, the predicate presents 11-18. The shaft of 510(k)-subject device is more rigid, or stiff, than the predicate. Other differences include some materials used in the construct of the devices. All materials used in the 510(k)-subject device are commonly used in medical devices.
Performance Data
Performance data demonstrates that the subject device is substantially equivalent to the predicate device and any differences between the devices were found not to affect safety or performance. The following were performed to demonstrate substantial equivalence to the predicate:
Sterilization & Shelf Life
The 510(k)-subject device will be sterilized by Cobalt 60 irradiation. The device will be validated to achieve 10to sterility assurance level (SAL).
The LINX Esophagus Sizing Tool has a validated shelf life based on results of an accelerated aging stability study.
Biocompatibility & Pyrogenicity
The biocompatibility of materials used in the LINX Esophagus Sizing Tool were evaluated based on ISO 10993-1:2018 - Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing and on FDA guidance, Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" issued on June 16, 2016.
The 510(k)-subject materials evaluated were determined to be non-pyrogenic.
