## Indications for Use

Sil-Tec Medical Grade rod is a soft, translucent silicon elastomer rod intended for reconstruction and surgical repair procedures. The rod is made in two grades of material: 1. The short term rods carry a catalog number with a suffix ST for short term procedures requiring implantation for less than 30 days. 2. The long term rods carry a catalog number with a suffix LT for implantation procedures requiring longer than 30 days. Some uses have been: 1. As temporary stents for the formation of new tendon sheaths 2. Other surgical repair procedures demanding a highly inert and flexible rod shaped material

## Device Story

Sil-Tec Rod is a soft, translucent silicone elastomer rod used in surgical reconstruction and repair. It functions as a passive implant, specifically serving as a temporary stent for tendon sheath formation or other surgical applications requiring flexible, inert material. Available in two grades: short-term (ST) for implantation <30 days and long-term (LT) for implantation >30 days. Used by surgeons in clinical/OR settings. Provides structural support or space maintenance during healing; benefits patient by facilitating tissue repair and reconstruction.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Material: Medical grade silicone elastomer. Form factor: Rod. Grades: Short-term (ST) and long-term (LT) based on implantation duration. Passive device; no energy source or software.

## Regulatory 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.

Dear Mr. Thompson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is 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 device, 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 device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device 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. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission 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.
