Regulatory Classification

Identification

An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" U.S. Food & Drug Administration 10903 New Hampshire Avenue Silver Spring, MD 20993 www.fda.gov {1} K250296 - Roshana Ahmed Page 2 (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Device Description The Disposable Distal Attachment D-201 Series is comprised of seven (7), sterile, single-use, distal attachments of varying diameters. Each distal attachment is a short transparent Page 1 of 4 {5} OLYMPUS Traditional 510(k) Disposable Distal Attachment D-201 Series plastic tube which is attached to the distal end of an endoscope to facilitate observation of tissues during endoscopic procedures. A subset of the models includes a drainage side hole that allows egress of water and blood during use. The Disposable Distal Attachment D-201 Series is to be used with compatible endoscopes. ## V. Indications for Use The Disposable Distal Attachment D-201 Series have been designed to be attached to the distal end of the endoscope to keep the suitable depth of endoscope's view field within the gastrointestinal tract. ## VI. Comparison of Technological Characteristics The subject device has the same intended use as the predicate device. The devices are intended to be attached to compatible endoscopes to keep the suitable depth of endoscope's view field within the gastrointestinal tract. The subject device and predicate device are straight transparent tubes which are attached to the distal end of endoscopes using medical tape to maintain a suitable depth of the field of view during endoscopic procedures. Except for variant D-201-11802, the subject device includes a side drainage hole to facilitate egress of fluids during endoscopic procedures. Furthermore, the subject device is provided sterile (via EtO) and is intended for single use. The subject and predicate device are offered in similar outer diameters; however, the subject device features a shorter length from the distal end of the endoscope than the predicate device. Bench testing, biological safety evaluation, sterilization validation, and shelf-life studies were undertaken on the subject device and predicate device to demonstrate substantial equivalence. A comparison of the subject and predicate device technological characteristics is provided below.
