The document describes a surgical stapler and its use with a robotic surgical system. There is no mention of AI or ML in the device description, intended use, or performance studies. The studies focus on mechanical and clinical performance, not algorithmic capabilities.
Yes
The device is described as a surgical stapler intended for resection, transection, and/or creation of anastomoses in various surgeries, which are therapeutic medical procedures.
No
Explanation: The device is described as a surgical stapler used for resection, transection, and creation of anastomoses, which are therapeutic actions, not diagnostic.
No
The device description clearly states it is a disposable, fully wristed, articulating, surgical stapler, which is a hardware device. The performance studies also describe bench and animal testing of the physical stapler and reloads.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) outside of the body to provide information about a person's health.
- Device Function: The description clearly states that the Intuitive Surgical 8 mm SureForm 30 staplers and reloads are used during surgery for "resection of vasculature and tissue and/or creation of anastomoses." This is an in vivo (within the living body) procedure.
- Intended Use: The intended use is for surgical procedures, not for analyzing samples in a laboratory setting.
- Device Description: The description focuses on the mechanical function of stapling and cutting tissue within the body.
- Performance Studies: The performance studies involve bench testing and animal models simulating surgical procedures, not laboratory analysis of human specimens.
The device is a surgical instrument used directly on the patient during an operation, which is the opposite of an in vitro diagnostic device.

Intended Use / Indications for Use
The Intuitive Surgical 8 mm SureForm 30 staplers and reloads and accessories are intended to be used with a compatible da Vinci Surgical system for resection of vasculature and tissue and/or creation of anastomoses in General, Thoracic, Gynecologic, Urologic, and Pediatric surgery.

Device Description
The Intuitive Surgical 8 mm SureForm 30 Curved-Tip Stapler and the 8 mm SureForm 30 Stapler are disposable, fully wristed, articulating, surgical staplers and are designed for use exclusively with the Intuitive Surgical da Vinci Xi and X Surgical Systems (Models IS4000 and IS4200 Systems). The staplers are controlled by the surgeon using the Surgeon Console of the IS4000/IS4200 Systems. They are intended for resection, transection and/or creation of anastomoses in surgery. The staplers achieve their intended use by placing multiple staggered rows of implantable staples in the target tissue (stapling) followed by cutting of the target tissue along the middle of the staple line (transection). The 8 mm SureForm 30 Reloads consist of a single-use cartridge that contains four staggered rows of implantable titanium alloy (Ti3A12.5V) staples. The reloads are offered in three configurations (gray, white, and blue). Each color represents a different staple leg height and tissue gap for use with various tissue thicknesses.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance test data (bench and animal tests) for the 8 mm SureForm 30 Staplers and Reloads 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.
Design Verification (bench):
The 8 mm SureForm 30 Staplers and Reloads were subject to full design verification testing included:
- Physical Specifications
- Mechanical Requirements
- Electrical Requirements
- User Interface Requirements
- Equipment Interface Requirements
- Reliability
- Packaging and labeling
The 8 mm SureForm 30 Staplers and Reloads met all of the bench testing acceptance criteria, demonstrating that that the design output meets the design input requirements.
Design Validation (animal):
A series of acute and chronic clinical validation studies were performed using simulated clinical models (animal) to evaluate the performance of the subject device.
Acute clinical validation studies included:
- Staple Line Performance: Assess staple line performance and staple formation of the subject device compared to the predicate. Animal Model: 3 canine models, 1 porcine model. Study Outcome: The subject device met all acceptance criteria and exhibited acceptable pass rates in the areas of transection, tissue layer approximation, hemostasis, and staple formation.
- Hemostasis: Assess hemostasis performance for the subject device as compared to the predicate device. Animal Model: 2 porcine models. Study Outcome: The subject device demonstrated equivalent hemostasis performance to the predicate device.

Study Outcome: All staple lines met all acceptance criteria and exhibited acceptable pass rates in leak onset pressure on thick (stomach) tissue and thin (vein) tissue.
- Maximum Torque: Evaluate staple line performance at maximum SmartFire torque limits of the subject device as compared to the predicate device. Animal Model: 2 canine models, 1 porcine model. Study Outcome: The 8 mm SureForm 30 Stapler and Reloads demonstrated clinically acceptable performance and met all design specifications. The subject device demonstrated equivalent clinical performance when compared to the predicate device in all adjacent fires. No new of issues of safety and efficacy were raised.
- Design Validation: Design validation testing of the subject device was performed in a clinical laboratory setting closely approximating an intraoperative use situation. Animal Model: 2 canine models, 2 porcine models. Study Outcome: The subject device met all acceptance criteria.
Chronic survival studies included:
- Lung Lobectomy Study: Assess subject device performance as compared to the predicate device in a lung lobectomy procedure. Animal Model: 8 canine models. Study Outcome: All staple lines passed assessments for leaks intraoperatively. All animals survived through the 28 day+ survival period. During the terminal procedures, there were no signs of bleeding or leakage at the staple lines. Staple lines were well-healed at the end of the survival period for both the subject and predicate devices.

differ in some design attributes (the subject device has a narrower diameter and shorter staple line length), indications for use (the subject device is indicated for use on vasculature and tissue), and patient-contacting materials (some same, some different).
Performance Data
Performance test data (bench and animal tests) for the 8 mm SureForm 30 Staplers and Reloads 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 (bench):
The 8 mm SureForm 30 Staplers and Reloads were subject to full design verification testing included:
- Physical Specifications ●
- Mechanical Requirements ●
- Electrical Requirements ●
- User Interface Requirements ●
- Equipment Interface Requirements ●
- Reliability ●
- Packaging and labeling
The 8 mm SureForm 30 Staplers and Reloads met all of the bench testing acceptance criteria, demonstrating that that the design output meets the design input requirements.
Design Validation (animal):
A series of acute and chronic clinical validation studies were performed using simulated clinical models (animal) to evaluate the performance of the subject device. Acute clinical validation studies included Staple Line Performance, Hemostasis Testing, Leak Onset Testing, Maximum Torque Evaluation, and Design Validation Testing. Chronic survival studies included Lung Lobectomy Study, Lung Wedge Resection Study, Gastrectomy Study, Small Bowel Anastomosis, and Nephrectomy Study. A side-by-side comparison between the subject and predicate device was performed in the Staple Line Performance, Hemostasis Testing, Leak Onset Testing, Maximum Torque Evaluation, and all Chronic Survival Studies to demonstrate substantial equivalence between the subject and predicate devices. Design Validation Testing demonstrated that the design outputs of the subject device fulfill the design input requirements and that user needs and intended uses are met.
