No
The device description and performance studies focus on a mechanical retractor and do not mention any AI or ML components or capabilities.
No.
The device is a surgical retractor used to assist in cesarean deliveries by providing incision retraction and protecting against wound contamination, which is a mechanical aid in a surgical procedure, not a therapeutic intervention to treat a disease or condition.
No
Explanation: The device is a surgical retractor used during cesarean deliveries to assist in incision retraction and wound contamination protection. It does not perform any diagnostic functions.
No
The device description clearly outlines physical components (flexible plastic rings, sleeve of plastic film) and their mechanical function (radial retraction of the incision site). This indicates a hardware-based medical device, not a software-only one.
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, or tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Device Function: The Apple Medical OB/Mobius Elastic Retractor is a surgical retractor. Its function is to physically hold open an incision during surgery and protect the wound. It does not analyze or test any biological samples.
- Intended Use: The intended use clearly states it is for "incision retraction" and "to protect against wound contamination during a cesarean section." This is a mechanical function performed on the body during a surgical procedure.
The description and intended use clearly indicate it's a surgical tool used directly on the patient during a procedure, not a device for testing samples in a lab setting.

Intended Use / Indications for Use
The Apple Medical OB/Mobius Elastic Retractor is indicated for use to assist in non-urgent cesarean deliveries that are routine procedures. It is intended to provide incision retraction and to protect against wound contamination during a cesarean section. It is indicated for use as a surgical retractor for both vertical and transverse incisions.

Device Description
The Apple Medical OB/Mobius® Elastic Retractor is a sterile disposable abdominal retractor consisting of two flexible plastic rings connected by a sleeve of soft, high yield strength, clear plastic film. The internal ring has a circular cross-section (o-ring) and the external ring has a cruciform cross-section (quad-ring). The inner diameter of the internal o-ring limits the radius of abdominal retraction. The diameter of the external quad-ring is the same as the diameter of the internal o-ring and the sleeve. When completely unwound, the height of the cylinder is 10.6 inches. When the quad ring is rolled down, the sleeve is wrapped around the circumference of the ring reducing the height of the sleeve by 1.5 inches per rotation. Because the sleeve film is radially unyielding, the reduction in height causes the radial retraction of the incision site.

§ 878.4800 Manual surgical instrument for general use.
(a)
Identification. A manual surgical instrument for general use is a nonpowered, hand-held, or hand manipulated device, either reusable or disposable, intended to be used in various general surgical procedures. The device includes the applicator, clip applier, biopsy brush, manual dermabrasion brush, scrub brush, cannula, ligature carrier, chisel, clamp, contractor, curette, cutter, dissector, elevator, skin graft expander, file, forceps, gouge, instrument guide, needle guide, hammer, hemostat, amputation hook, ligature passing and knot-tying instrument, knife, mallet, disposable or reusable aspiration and injection needle, disposable or reusable suturing needle, osteotome, pliers, rasp, retainer, retractor, saw, scalpel blade, scalpel handle, one-piece scalpel, snare, spatula, stapler, disposable or reusable stripper, stylet, suturing apparatus for the stomach and intestine, measuring tape, and calipers.

| Description | The Apple Medical OB/Mobius® Elastic Retractor is a sterile disposable
abdominal retractor consisting of two flexible plastic rings connected by a
sleeve of soft, high yield strength, clear plastic film. The internal ring has
a circular cross-section (o-ring) and the external ring has a cruciform
cross-section (quad-ring). The inner diameter of the internal o-ring limits
the radius of abdominal retraction. The diameter of the external quad-ring
is the same as the diameter of the internal o-ring and the sleeve. When
completely unwound, the height of the cylinder is 10.6 inches. When the
quad ring is rolled down, the sleeve is wrapped around the circumference
of the ring reducing the height of the sleeve by 1.5 inches per rotation.
Because the sleeve film is radially unyielding, the reduction in height
causes the radial retraction of the incision site. |
| Intended Use | The Apple Medical OB/Mobius Elastic Retractor is indicated for use to
assist in non-urgent cesarean deliveries that are routine procedures. It is
intended to provide incision retraction and to protect against wound
contamination during a cesarean section. It is indicated for use as a
surgical retractor for both vertical and transverse incisions. |
| Technological
Characteristics | The internal o-ring is manually collapsed and inserted through the
abdominal incision where it is allowed to spring open against the parietal
peritoneum. The external quad-ring is then pulled upward placing the
cylindrical sleeve in tension and the operator rolls the ring down the
sleeve until the ring sits firmly against the skin. The radial force of the
two rings acts to retract the abdominal wall to the desired circular
geometry. |
| Testing | The Apple Medical OB/Mobius Elastic Retractor has been clinically
evaluated for the cesarean section indication and shown to be
substantially equivalent to the predicate mechanical abdominal retractors. |

Dear Mr. Delaney:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
