The Intuitive Surgical Endoscopic Instrument Control System, Model IS4000) is intended to assist in the accurate control of Intuitive Surgical Endoscopic Instruments including rigid endoscopes, blunt and sharp endoscopic dissectors, scissors, scalpels, forceps/pick-ups, needle holders, endoscopic retractors, electrocautery and accessories for endoscopic manipulation of tissue, including grasping, blunt and sharp dissection, approximation, ligation, electrocautery, suturing, and delivery and placement of microwave and cryogenic ablation probes and accessories, during urologic surgical procedures, general laparoscopic surgical procedures, gynecologic laparosopic surgical procedures, general thoracoscopic surgical procedures and thoracoscopically assisted cardiotomy procedures. The system can also be employed with adjunctive mediastinotomy to perform coronary anastomosis during cardiac revascularization. The system is indicated for adult and pediatric use. It is intended to be used by trained physicians in an operating room environment in accordance with the representative, specific procedures set forth in the Professional Instructions for Use.
This 510(k) is for a labeling modification only, to include the following additional representative, specific procedures under the cleared "thoracoscopic surgical procedures and thoracoscopically-assisted cardiotomy procedures" general indication for the da Vinci Xi Surgical System (K131861): Lobectomy, Mediastinal Mass Resection, Thymectomy, Segmentectomy, Wedge Resection and Lymphadenectomy. There are no changes to the technological characteristics of the cleared da Vinci Xi Surgical System proposed in this submission. The da Vinci Xi Surgical System, Model IS4000 is a software-controlled, electro-mechanical system designed for surgeons to perform minimally invasive surgery. The Model IS4000 Surgical System consists of a Surgeon Console, a Patient Side Cart (PSC), and a Vision Side Cart (VSC) and is used with an Endoscope, EndoWrist Instruments, and Accessories.
The provided text describes a 510(k) premarket notification for the Da Vinci Xi Surgical System, focusing on a labeling modification to include additional specific procedures under existing general indications for use. This involves demonstrating substantial equivalence to predicate devices, rather than establishing entirely new performance criteria for a novel device. Therefore, the information typically requested regarding acceptance criteria and a study proving a new device meets those criteria is not directly applicable in this context as new performance metrics are not being established.
However, I can extract and structure the available information about the demonstration of suitability for the expanded indications, which functions as the system's "acceptance" for these new procedures.
Here's an interpretation based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria here are implicitly demonstrating that the da Vinci Xi Surgical System, when used for the expanded "umbrella" and "covered" procedures, shows comparable or improved patient outcomes (mortality, complications, blood loss, length of stay, operative time) compared to established surgical methods (Open and VATS procedures).
| Acceptance Criteria (Comparable to Predicate or Established Methods) | Reported Device Performance (da Vinci-assisted procedures) |
|---|---|
| Lobectomy | - Mortality Rates: Comparable or lower. |
- Complications: Comparable.
- Blood Transfusion Rates: Comparable or lower.
- Length of Hospital Stay: Comparable or shorter.
- Operative Times: Comparable or shorter (5 studies), or increased (13 studies) (but no correlation with increased mortality).
- Conversion Rates: Comparable or lower compared to VATS. |
| Mediastinal Mass Resection | - Mortality Rates: Comparable. - Operative Times: Comparable.
- Complication Rates: Comparable or lower.
- Length of Hospital Stay: Comparable or shorter compared to open surgical procedures.
- Single-arm studies: No reports of mortality, low complication rates (intraoperative
§ 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.
