The summary describes a physical probe used with existing lasers and does not mention any software, algorithms, or data processing that would indicate AI/ML. The "Mentions AI, DNN, or ML" and "Mentions image processing" sections are explicitly marked as "Not Found".
Yes
Explanation: The device is intended for "reduction of intra ocular pressure (IOP) in glaucoma patients" and "ablates the Ciliary Body," which are direct medical treatments.
No
The device is described as a surgical probe for a therapeutic procedure (cyclophotocoagulation) to reduce intraocular pressure, not for diagnosing a condition.
No
The device description clearly outlines physical components (handgrip, tip, focusing lens, fiber) and a manufacturing process (presterilized, disposable), indicating it is a hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body ("in vitro").
- Device Function: The described device, the TSX Probe, is a surgical instrument used directly on the patient's eye to deliver laser energy for a therapeutic procedure (reducing intraocular pressure). It does not analyze any bodily specimens.
Therefore, based on its intended use and function, the TSX Probe is a surgical instrument, not an IVD.

Intended Use / Indications for Use

Device Description
The TSX Probe consists of three basic parts; handgrip, tip and focusing lens and is a presterilized (Ethylene Oxide) disposable contact probe. Its tip is a clear amber medical plastic that is angled to match the curvature of the human eye and therefore allows for the placement of the probe vertically, closest to the limbus. The angle of the contact tip (distal end) conforms to the curvature of the eye. The three-meter 600 um fiber plugs into an HGM SmartScan™ laser or other SMA connection compatible device allows the physician to perform noninvasive contact CYC with marketed (approved) infrared lasers.

(a)
Identification. (1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

Summary of Safety and Effectiveness for:
Trade Name: TSX Probe
Common Name: Laser Delivery Device, Ocular Contact Probe
Classification Name: Laser, Ophthalmic, Accessory
Legally Marketed Predicate Devices for Substantial Equivalence:
- Iris G-Probe, Manufactured by Iriderm Division, Laser Instrument, Surgical, Powered
Rationale for SE:
The Iris G-Probe is a sterile single use delivery device for the reduction of intra ocular pressure (IOP) in glaucoma patients. A three meter, 600 um fiber delivers the light energy from the laser to the focusing lens. The g-probe is furnished as sterile to the customer. The treatment performed using this non-invasive contact probe allows for selective ablation of ciliary processes. The procedure, Transscleral Cyclophotocoagulation (CYC), causes less postoperative pain and inflammation and is an alternative treatment from Cyclocryotherapy. The device is compatible with infrared photocoagulators.
Description of Submitted Device:
The TSX Probe consists of three basic parts; handgrip, tip and focusing lens and is a presterilized (Ethylene Oxide) disposable contact probe. Its tip is a clear amber medical plastic that is angled to match the curvature of the human eye and therefore allows for the placement of the probe vertically, closest to the limbus. The angle of the contact tip (distal end) conforms to the curvature of the eye. The three-meter 600 um fiber plugs into an HGM SmartScan™ laser or other SMA connection compatible device allows the physician to perform noninvasive contact CYC with marketed (approved) infrared lasers.

Intended Uses of the TSX Probe:
See attachment "5" for a complete listing of indicated uses.
Technological Characteristics and Substantial Equivalence:
The TSX Probe is similar to the G-Probe, both have a 600 um fiber which delivers the treatment light to the tip of the contact probe. The TSX Probe is sleeker having a contact tip which is smaller than the G-Probe. Both offer treatment modalities for laser light delivery to ocular tissue, for various types of glaucoma in it's advanced stages. The probes are moved in a circular fashion around the cornea using the limbus as a circular guide. Both probes allow laser energy to be fired at regular intervals into the ciliary body. The two probes are similar in design, intended use, and compatible with lasers widely in use.
Conclusion:
The TSX Probe is substantially equivalent to other existing laser surgical delivery devices already in commercial distribution. The labeling of the TSX Probe as a single-use pre-sterilized delivery device for treatment of (CYC) is an addition to a large field of Ophthalmic treatment methods with medical lasers.
