No
The device description clearly states it is a manual surgical instrument with a purely mechanical function for tissue retraction. There is no mention of any computational or data-driven components.
No
The device is a surgical instrument used for tissue retraction during procedures, not for treating or diagnosing a disease or condition.
No
The Flexposure Retractor is a manual surgical instrument used for tissue retraction during endoscopic discectomy procedures, which is a therapeutic function, not a diagnostic one.
No
The device description clearly states it is a manual surgical instrument made of medical grade stainless steel and heat shrink polyester material, describing its physical components and mechanical function. It is not software.
Based on the provided information, the Flexposure Retractor is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- The Flexposure Retractor is a surgical instrument used during a surgical procedure (endoscopic discectomy) to physically retract tissues and provide access to the surgical site. It does not analyze or test any biological samples.
The description clearly indicates it's a manual surgical tool for physical manipulation of tissues during surgery, not for in vitro testing.

Device Description
The Flexposure Retractor is a manual surgical instrument intended for use in posterior endoscopic microdiscectomy procedures. It is essentially a standard retractor designed to improve exposure of the surgical site. The Flexposure Retractor looks like a standard retractor/tube like device with the exception of the distal end. The distal end of the device can expand to better retract tissues from the operative site. The device includes a tip release line which is attached to an outer heat shrink polyester material. The purpose of the heat shrink polyester material is to maintain the retractor in the closed position. The remainder of the device is made from medical grade stainless steel.
The Flexposure Retractor is placed several centimeters lateral to the midline of the back through a cannula. The tip of the Retractor is positioned on the lamina. After positioning, the user pulls the tip release line which causes the heat shrink polyester material to split. The splitting of the heat shrink material allows for the expansion of the tip of the cannula. A mechanical hand held retractor is inserted through the cannula and opened causing the flexible stainless steel skirt of the retractor to be expanded to approximately a 25 mm dimension.

It is essentially a standard retractor designed to improve exposure of the surgical site. The Flexposure Retractor looks like a standard retractor/tube like device with the exception of the distal end.

material is to maintain the retractor in the closed position. The remainder of the device is made from medical grade stainless steel.
The Flexposure Retractor is placed several centimeters lateral to the midline of the back through a cannula. The tip of the Retractor is positioned on the lamina. After positioning, the user pulls the tip release line which causes the heat shrink polyester material to split. The splitting of the heat shrink material allows for the expansion of the tip of the cannula. A mechanical hand held retractor is inserted through the cannula and opened causing the flexible stainless steel skirt of the retractor to be expanded to approximately a 25 mm dimension.
ട്. INTENDED USE
The Flexposure Retractor is a disposable manual surgical instrument intended to provide endoscopic access to the posterior lumbar spine by retracting tissues during endoscopic discectomy procedures.
TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.
The Endius Incorporated Flexposure Retractor is substantially equivalent to several legally marketed retractors including the retractor included in the Sofamor Danek MED Microendoscopic Discectomy, K955471, K950501 and K950130.
Both the Endius Retractor and the predicate Sofamor Danek retractor are intended to provide endoscopic access to the posterior lumbar spine by retracting tissues during endoscopic discectomy procedures.
Both the Endius Retractor and the predicate Sofamor Danek retractor are similar in that they are inserted over step dilators to push the tissues away from the operative site. The Endius Retractor is different in that the distal tip of the retractor expands to provide improved endoscopic access to the posterior lumbar spine. This difference does not compromise safety or effectiveness of the device since the device functions essentially identical to the predicate device in retracting tissues. The only difference is the method of retraction. The materials of manufacture of both the proposed and predicate devices are medical grade stainless steel.
Based on the above discussion and the comparison chart below, Endius Incorporated believes that the Flexposure Retractor is substantially equivalent to the Sofamor Danek Retractor of the MED System.

Dear Ms. McNamara-Cullinane:
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 requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) 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.
