Intended Use
The Medline ReNewal Reprocessed Versaport V2 Bladeless Optical Trocar is intended for use in a variety of gynecologic, general, thoracic and urologic endoscopic procedures to create and maintain a port of entry. The trocar may be used with or without visualization for primary and secondary insertions.
Device Story
Reprocessed single-use surgical trocar; enables port of entry for endoscopic procedures. Input: manual insertion by surgeon; accommodates 0° laparoscope for optical visualization of tissue layers. Operation: bladeless obturator creates entry; cannula maintains port; internal seals prevent pneumoperitoneum loss during instrument exchange. Used in OR by surgeons. Output: established surgical port. Benefits: provides access for minimally invasive surgery; reprocessed to reduce waste while maintaining original device functionality.
Clinical Evidence
Bench testing only. No clinical data. Performance testing included simulated use, artificial soiling, seal leakage, seal drag, surface roughness, visualization, cleaning performance qualification, biocompatibility (cytotoxicity, irritation, sensitization, pyrogenicity, acute systemic toxicity), and sterilization/packaging validation.
Technological Characteristics
Reprocessed single-use surgical trocar. Components: transparent cannula, bladeless obturator with optical window, scope retention mechanism, internal seals, three-way stopcock. Diameters: 5-mm, 11-mm, 12-mm. Lengths: 70-mm, 100-mm, 150-mm. Sterilization: Ethylene oxide.
Indications for Use
Indicated for patients undergoing gynecologic, general, thoracic, or urologic endoscopic procedures requiring a port of entry. No specific age or gender contraindications provided.
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.
Special Controls
*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.
