The SimpleStitch Suturing System is intended for endoscopic placement of suture(s) and approximation of soft tissue (e.g., closure and healing of ESD/EMR sites, and closing of fistula, perforation or leaks).
The SimpleStitch Suturing System ("SimpleStitch SS") is a sterile, single patient-use device that enables endoscopic placement of sutures and approximation of soft tissue within the gastrointestinal tract using a flexible endoscope. The system includes the following components: SimpleStitch Suture Device, SimpleStitch Suture Cartridge, and SimpleStitch Suture Cinch. The SimpleStitch SS is designed for compatibility with single-channel endoscopes (gastroscopes and colonoscopes) with a minimum working channel inner diameter of 2.8mm. During use, the suturing device/suture cartridge is mounted to the endoscope's exterior; the cinching device goes through the endoscope's working channel. The SimpleStitch SS is available with a USP 2-0 and USP 0 nonabsorbable polyester suture. Tissue is secured using a cinch anchor once tissue approximation is complete.
This FDA 510(k) clearance letter and summary is for a physical medical device (SimpleStitch Suturing System), not an AI/Software as a Medical Device (SaMD). Therefore, the information typically requested for AI/SaMD performance studies (such as acceptance criteria for algorithm performance, sample size for test sets with ground truth, number of experts for ground truth, MRMC studies, standalone performance, training set details, etc.) is not applicable here.
The document focuses on demonstrating substantial equivalence to a predicate device (OverStitch Endoscopic Suturing System) through:
- Comparison of Technological Characteristics: Showing similarities in intended use, indications for use, principle of operation, materials, and design.
- Performance Data: Primarily bench testing (dimensional verification, functionality, destructive testing, side-by-side comparison with predicate, usability, packaging, shelf-life), biocompatibility, MRI safety, and an animal (swine) survival study.
There is no mention of an algorithm or AI model, nor any associated acceptance criteria, ground truth establishment, or statistical performance metrics typically associated with AI/SaMD.
Therefore, I cannot provide the requested information regarding acceptance criteria and study proof in the context of an AI/SaMD for this document.
§ 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.
