No
The device description and intended use clearly describe a physical implant material made of silicone, with no mention of software, algorithms, or any form of computational processing. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".
Yes.
The device is used as an implant material to aid in surgical reconstructions, specifically for vocal fold medialization and augmentation, which are therapeutic interventions.
No
The device description indicates that the Xomed Silicone Pre-form Blocks are implants used for surgical reconstruction, specifically for vocal fold medialization and augmentation. They are "space occupying material" and are "trimmed and shaped to size" by the surgeon for the patient's needs. This is a therapeutic device, not a diagnostic one.
No
The device description clearly states it is a sterile supplied implant made from silicone elastomer, which is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is as an implant material for surgical reconstruction in laryngeal procedures. This is a therapeutic and structural function within the body, not a diagnostic test performed on samples outside the body.
- Device Description: The device is a sterile implant made of silicone elastomer, designed to be surgically placed within the larynx. This aligns with a medical device for treatment or structural support, not an IVD.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information based on in vitro testing.
IVDs are devices used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
Xomed Silicone Pre-form Blocks are sterile supplied implants made from silicone elastomer molded into a pre-form sizes as specified on the product label. Metric graduations on the implant surface helps in sizing the implant for patient need. The implants are to be trimmed and shaped to size by the surgeon for individual patient needs. The devices are intended for single patient use only. As a prescription device, the surgeon should be familiar with the skills and training for laryngeal reconstruction and vocal fold augmentation with silicone implants.

§ 874.3620 Ear, nose, and throat synthetic polymer material.
(a)
Identification. Ear, nose, and throat synthetic polymer material is a device material that is intended to be implanted for use as a space-occupying substance in the reconstructive surgery of the head and neck. The device is used, for example, in augmentation rhinoplasty and in tissue defect closures in the esophagus. The device is shaped and formed by the suregon to conform to the patient's needs. This generic type of device is made of material such as polyamide mesh or foil and porous polyethylene.(b)

5.0 Device Description
Xomed Silicone Pre-form Blocks are sterile supplied implants made from silicone elastomer molded into a pre-form sizes as specified on the product label. Metric graduations on the implant surface helps in sizing the implant for patient need. The implants are to be trimmed and shaped to size by the surgeon for individual patient needs. The devices are intended for single patient use only. As a prescription device, the surgeon should be familiar with the skills and training for laryngeal reconstruction and vocal fold augmentation with silicone implants.
6.0 Intended Use
The Silicone Pre-form Blocks are intended for use as an implant material for surgical to aid in surgical reconstructions as a space occupying material in laryngeal surgical procedure for vocal fold medialization and augmentation.
7.0 Substantial Equivalence
Xomed markets both silicone blocks and strips for implant uses in head and neck surgery by K970910. The Silicone Pre-form Blocks are substantially equivalent to these predicate products in that they are made from the same material which has satisfactory biocompatibility approval for implant applications. Additionally, the Silicone elastomer Pre-form Blocks are similar to the Montgomery Thyroplasty Implants, Boston Medical Products K972317 for the intended use in thyroplasty procedures involving medialization and augmentation of the vocal fold. The difference is the Xomed Pre-form Blocks are to be trimmed to final shape and size by the surgeon for the individual patient needs while the Montgomery silicone elastomer implants are predetermined sized silicone augmentation devices requiring no alteration at surgery.
