Colonoscope/Sigmoidoscope Sheaths are meant for use in non-sterile colonoscopy or sigmoidoscopy procedures to help reduce gross contamination of the endoscope, reducing the exposure of staff to gross contamination during the cleaning procedure.
The Sheathing Technologies, Inc. Polyurethane Colonoscope/Sigmoidoscope Sheath provides a conformal covering to fit various lengths and widths of colonoscopes and sigmoidoscopes (hereafter referred to as 'endoscopes'). The cover is open at the proximal end to allow free use of the endoscope's channels, and open at the distal end for insertion of the endoscope. Various sizes and shapes of Sheaths are offered to address the variations in size of the endoscopes.
This device is an accessory for use in nonsterile colonoscopy or sigmoidoscopy procedures to help reduce gross contamination of the endoscope, reducing the exposure of staff to gross contamination during the cleaning procedure.
The cover material is a polyether-blend polyurethane, which is the same blend currently used for Sheathing Technologies probe covers (510(K) K963831 for Sheathes Non-Latex, Non-Sterile and 510(K) K990175 for Sheathes Non-Latex, Sterile).
Product categories/models include
- Rigid sigmoidoscope Sheaths (sterile and non-sterile)
- Flexible sigmoidoscope Sheaths (sterile and non-sterile)
- Colonoscope Sheaths (sterile and nonsterile)
Sheaths are packaged in both sterile and nonsterile, individually wrapped or in bag/box quantities. All are intended for non-sterile procedures, and all are for single patient/procedure, disposable use.
The provided text describes a 510(k) submission for a Colonoscope/Sigmoidoscope Sheath. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through extensive clinical trials with strict acceptance criteria often seen with novel high-risk devices.
Therefore, the information regarding acceptance criteria and a study proving the device meets those criteria, as typically understood in a clinical efficacy context, is not present in the provided document. The submission relies on non-clinical bench testing and biocompatibility assessments to support equivalence.
Here's an analysis based on the provided text, addressing your questions to the extent possible:
1. A table of acceptance criteria and the reported device performance
No explicit "acceptance criteria" table with corresponding device performance values for clinical efficacy is provided. The non-clinical tests' conclusions state: "Sheathing Technologies's Polyurethane sigmoidoscope/colonoscope Sheath has sufficient strength and elasticity for the intended application. It is biocompatible according to the ISO 10993-1:2003 biocompatibility standard for contact with skin and mucous membranes for a limited (
§ 876.1500 Endoscope and accessories.
(a)
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.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
