More Information

No
The summary describes a software-controlled, electro-mechanical surgical system and its accessories, focusing on mechanical components, access ports, and surgical procedures. There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies.

Yes.

The device is intended to assist in the accurate control of surgical instruments for performing various surgical procedures, which constitutes a therapeutic use.

No

Explanation: The document describes the da Vinci SP Surgical System as aiding in the "accurate control of Intuitive Surgical® EndoWrist SP ™ Instruments during urologic surgical procedures" and for performing "minimally invasive surgery." Its components are for surgical access, manipulation of tissue, and vision, none of which are inherently diagnostic functions. The device is used for active surgical intervention, not for identifying, monitoring, or predicting disease.

No

The device description explicitly states that the da Vinci SP® Surgical System is a "software-controlled, electro-mechanical system" and includes physical components like a Surgeon Console, Patient Cart, Vision Cart, instruments, and accessories. While software is a component, it is not a software-only device.

Based on the provided text, the device described is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the system is for assisting in the control of surgical instruments during urologic and transoral otolaryngology surgical procedures. This involves direct interaction with the patient's body during surgery.
  • Device Description: The description details a surgical system with a surgeon console, patient cart, vision cart, instruments, and accessories like the SP Access Port Kit. These are all components used in surgical procedures.
  • Lack of IVD Characteristics: An IVD device is intended for use in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The description of the da Vinci SP system and its accessories does not involve the analysis of such specimens.

The device is a surgical system designed for performing minimally invasive surgery, which is a different category of medical device than an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance test data (bench, animal, and cadaver tests) for the SP Access Port Kit demonstrate that the subject device is substantially equivalent to the predicate device and that the design output meets the design input requirements, user needs, and intended use. The testing is summarized below.

Design Verification Testing (Bench Testing): The SP Access Port Kit was subjected to full design verification to specifications including: Physical specifications, Mechanical requirements, Equipment interfaces, Reliability, Package and labeling. The SP Access Port Kit met all the bench testing acceptance criteria, demonstrating that the design output meets the design input requirements.

Cadaver and Animal Validations: Design validation was performed to confirm the clinical performance of the da Vinci SP® Surgical System, including the SP Access Port Kit, under its intended use. A complete retroperitoneal nephrectomy procedure was performed using the SP Access Port Kit in a cadaver model, and a complete transabdominal nephroureterectomy procedure was completed in a porcine model. Testing evaluated:

  • Retroperitoneal Nephrectomy (Cadaver): Assessment of the SP Access Port Kit to provide robotic and laparoscopic instrument access to the extraperitoneal space, superficial anatomy, and anatomy near bony structures.
  • Nephroureterectomy (Porcine): Evaluation of the ability to provide robotic and laparoscopic instrument access to a large surgical work volume (access to multiple quadrants of the body and a range of instrument depths). Assessment of instrument motion during fine dissection tasks and gross movements. Evaluation of SP Access Port Kit robustness as well as the ability of the SP Access Port Kit to maintain insufflation and remain securely installed during use.

The da Vinci SP® Surgical System, Model SP1098, EndoWrist SP™ Instruments, and Accessories, including the SP Access Port Kit, met all the design validation acceptance criteria, demonstrating that it meets user needs and intended use.

Histological Evaluation: The SP Access Port Kit underwent testing to compare its effect on the port site tissue to that of the SP Cannula (predicate device, K182371) and the GelPOINT access device (reference device, K090275) as a result of installation, incision retraction under insufflation, and removal of the port in a porcine model. Also, the extent of tissue trauma at the port site and surrounding organs due to use of the SP Access Port Kit or the SP Cannula (predicate device) during completion of a left nephroureterectomy procedure with the da Vinci SP® Surgical System and EndoWrist SP™ instruments was evaluated in porcine models. For both tests, an independent pathologist evaluated the extent of tissue trauma by assessing, at a minimum, hemorrhage, necrosis and inflammation. The tissue trauma assessments were compared between devices to determine pathologically significant differences.

The pathologist concluded the following:

  • There were no discernible pathologically significant differences between any of the tissue tracks examined from the SP Access Port Kit, SP Cannula (predicate device) and GelPOINT (reference device) port sites as a result of installation, incision retraction, and removal of the port.
  • There were no discernible pathologically significant differences between the tissue tracks from the SP Access Port Kit and the SP Cannula used to perform a left nephroureterectomy.
  • Based on gross visual examination immediately after completion of the procedures, there was no trauma to surrounding organs due to the installation, removal, incision retraction, and use of the SP Access Port Kit or SP Cannula during the surgical procedures that required further histopathological examination.
  • All the samples in this study would heal normally and adequately once appropriate tissue apposition and suture closure was performed.

Human Factors Evaluation: A summative validation study was conducted to evaluate high-risk use scenarios and essential tasks associated with the use of the SP Access Port Kit. This study was conducted in a simulated operating room and involved preoperative preparation and simulated surgical procedures that involved safety-critical tasks. A total of 16 surgical teams (surgeon and patient-side assistant) participated in the study. Objective performance data included observations of users' ability to complete tasks, use errors, close calls, and any difficulties encountered. Subjective feedback included open-ended questions about risks and safety, and follow-up interviews. The safety and usability of the SP Access Port Kit were assessed to ensure that residual risk is at an acceptable level, and new hazardous use scenarios identified during testing were assessed according to an accepted risk management process and updated in the usability risk analysis for the SP Access Port Kit.

INTUITIVE da Vinci SP® Surgical System (including SP Access Port Kit) K202571

The da Vinci SP® Surgical System, Model SP1098, EndoWrist SP™ Instruments, and Accessories, including the SP Access Port Kit, met all the design validation acceptance criteria, demonstrating that it meets user needs and intended use.

Histological Evaluation

The SP Access Port Kit underwent testing to compare its effect on the port site tissue to that of the SP Cannula (predicate device, K182371) and the GelPOINT access device. (reference device, K090275) as a result of installation, incision retraction under insufflation, and removal of the port in a porcine model. Similar to the SP Access Port Kit, the GelPOINT device is used as a port to enable access of multiple instruments through a single incision for abdominal surgery. It also includes a component for wound retraction and a component for maintaining insufflation before, during, and after the insertion, use, and removal of instruments, like the SP Access Port Kit.

Also, the extent of tissue trauma at the port site and surrounding organs due to use of the SP Access Port Kit or the SP Cannula (predicate device) during completion of a left nephroureterectomy procedure with the da Vinci SP® Surgical System and EndoWrist SP™ instruments was evaluated in porcine models. For both tests, an independent pathologist evaluated the extent of tissue trauma by assessing, at a minimum, hemorrhage, necrosis and inflammation. The tissue trauma assessments were compared between devices to determine pathologically significant differences.

The pathologist concluded the following:

  • . There were no discernible pathologically significant differences between any of the tissue tracks examined from the SP Access Port Kit, SP Cannula (predicate device) and GelPOINT (reference device) port sites as a result of installation, incision retraction, and removal of the port.
  • There were no discernible pathologically significant differences between the . tissue tracks from the SP Access Port Kit and the SP Cannula used to perform a left nephroureterectomy .
  • . Based on gross visual examination immediately after completion of the procedures, there was no trauma to surrounding organs due to the installation, removal, incision retraction, and use of the SP Access Port Kit or SP Cannula during the surgical procedures that required further histopathological examination.
  • All the samples in this study would heal normally and adequately once . appropriate tissue apposition and suture closure was performed.

Clinical Validation

No clinical testing was required to support substantial equivalence.

Human Factors Evaluation

The human factors (HF) engineering process was followed in accordance with the following:

  • . ANSI/AAMI/IEC 62366-1:2015, Medical devices - Application of usability engineering to medical devices
  • FDA, 2016, Applying Human Factors and Usability Engineering to Medical . Devices - Guidance for Industry and Food and Drug Administration Staff

The usability risk analysis for the SP Access Port Kit was developed with feedback from internal functional group experts, using cognitive walk-through, experience from prior products, and internal testing to identify use-related risks. This usability risk analysis was updated throughout the SP Access Port Kit design process as formative testing was conducted, the design was iterated, new use errors were identified, and new mitigations were implemented. Formative testing was conducted on complete kit prototypes and on individual features of the user interface design. Those tests, along with information about the use of the da Vinci SP® Surgical System (Model SP1098) helped identify use-related risks for the SP Access Port Kit.

A summative validation study was conducted to evaluate high-risk use scenarios and essential tasks associated with the use of the SP Access Port Kit. This study was conducted in a simulated operating room and involved preoperative preparation and simulated surgical procedures that involved safety-critical tasks. Training materials and user manuals were developed in concert with the product and were assessed in the validation study. The goals of human factors validation testing were to:

  • Validate risk mitigations to ensure use-safety and effectiveness of the SP Access . Port Kit
  • Assess any previously unknown use-related hazards, or identify and assess any . hazards resulting from implemented mitigations
  • Evaluate ease of use
  • Assess effectiveness of user documentation (i.e., user manual and graphical . assembly/disassembly instructions)
  • Assess effectiveness of training material .

A total of 16 surgical teams (surgeon and patient-side assistant) participated in the study. Surgeon participants exhibited a wide range of years in surgical practice and robotic

surgical experience. Patient-side assistants who participated in the study also varied widely in surgical experience and robotic surgical experience. Prior to the evaluation, participants underwent representative self-guided training that a user would be provided for the SP Access Port Kit. The testing sessions were conducted in a simulated operating room environment, which included overhead operating room lighting, an adjustable patient table, and accessory equipment (e.g. anesthesia equipment, energy equipment, insufflator, etc.). Participants were asked to use sterile technique within the surgical field. In addition to the normal use situation of performing the necessary tasks to complete surgical procedures, imposed scenarios were interjected to test use scenarios that may not occur during normal operation of the system. Data collected included both objective performance data and subjective feedback from participants. Objective performance data included observations of users' ability to complete tasks, use errors, close calls, and any difficulties encountered. Subjective feedback included open-ended questions about risks and safety, and follow-up interviews.

The human factors engineering process, culminating in a summative usability validation study, was used to identify and assess the use-related risks associated with the SP Access Port Kit. The safety and usability of the SP Access Port Kit were assessed to ensure that residual risk is at an acceptable level, and new hazardous use scenarios identified during testing were assessed according to an accepted risk management process and updated in the usability risk analysis for the SP Access Port Kit.

Conclusion

Based on the intended use, indications for use, technological characteristics and performance data, the Intuitive Surgical da Vinci SP® Surgical System, Model SP1098, Endo Wrist SPTM Instruments, and Accessories, including the SP Access Port Kit, have been assessed and found to be substantially equivalent (SE) to the predicate devices. This SE determination is based on performance testing that included: bench testing, cadaver and animal testing with simulated and representative urologic surgical procedures, and a human factors evaluation. This testing verified and validated that the SP Access Port Kit can be used safely and effectively with the system, instruments, and other accessories, as well as with third-party laparoscopic instruments and surgical accessories, in accordance with the instructions for use to successfully complete the representative urologic surgical procedures encompassed by the indications for use statement.
