The PVS 1700 Steerable Delivery System®-10 Microcatheter is intended to be used to access tortuous vasculature for sub-selective controlled infusion or delivery of diagnostic, embolic, and therapeutic agents into the distal, peripheral, coronary, and neurovasculature, and for guide wire exchange/support during diagnostic or interventional procedures.

The PVS 1700 Steerable Delivery System®-10 is a 1.9F/2.4F (nominal distal/proximal) tubular device, 155 cm in length, with a lumen to be used for delivery of contrast, drugs, or embolics. The lumen is constructed from a polymeric material and has an inside diameter of 0.0165". The device is coated on the outer diameter with a lubricious coating over the distal segment of the device. Two radiopaque markers are positioned at the distal tip of the device to aid visualization under fluoroscopy. The proximal end of the device has a standard luer adapter for attachment of accessories and can be used to flush the lumen. The subject device has the ability to access distal, tortuous vasculature over a guide wire, deliver embolics and agents, and has the ability to be steered like a guide wire as needed.

The provided document is a 510(k) summary for a medical device (PVS 1700 Steerable Delivery System®-10 Microcatheter), which focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed clinical study results for novel acceptance criteria.

Therefore, many of the requested details about specific acceptance criteria from a clinical study, sample size, expert ground truth establishment, and MRMC studies are not applicable or available in this type of regulatory submission. The device is primarily evaluated through bench testing and comparison to existing, cleared devices.

Here's an analysis of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in a quantitative, pass/fail manner for each test, nor does it provide detailed performance numbers in a table. Instead, it generally states that tests "yielded acceptable results" or "confirmed biocompatibility."

The provided document describes the PVS 1600 Synchro® 0.010" Neuro Guidewire and its demonstration of substantial equivalence to predicate devices, rather than a study with specific acceptance criteria and detailed performance metrics as would typically be presented for a new or significantly modified device under a comprehensive clinical trial.

However, based on the information provided, I can extract the relevant details regarding the safety and performance tests conducted to support its substantial equivalence.

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not specify quantitative acceptance criteria with corresponding performance statistics in a tabular format as one would expect from a controlled study with predefined thresholds. Instead, it states that "Subject product testing has yielded acceptable safety & performance outcomes" and that tests "also yielded acceptable results." The criteria are implied to be met if the PVS 1600 Synchro® 0.010" Neuro Guidewire is comparable to its predicate devices and conforms to relevant standards.

Therefore, the table below provides the performance tests conducted and the general outcome stated in the document. The "Acceptance Criteria" are inferred from the context of demonstrating substantial equivalence to predicate devices and adherence to relevant standards (ISO 10993-1, ISO 11070:1998).

These guidewires are intended for use in percutaneous procedures to introduce and position catheters and other interventional devices within the coronary and peripheral vasculature.

The PVS 1400 Guidewire is a 0.014" outside diameter, single-use guidewire, which is used to gain intravascular access to and to facilitate the positioning and exchange of catheters in small diameter, tortuous vasculature for coronary and peripheral diagnostic or interventional procedures. The wire can be torqued to facilitate navigation through the vasculature. The proximal wire material is stainless steel. The guidewire is coated to provide lubricity. The tip material of the guidewire is nitinol.

Here's an analysis of the provided text regarding the PVS 1400 Guidewire, focusing on acceptance criteria and supporting studies:

1. Table of Acceptance Criteria and Reported Device Performance:

The document describes performance criteria for various physical characteristics of the guidewire. Acceptance for these criteria is demonstrated by achieving "similar," "better," or meeting specific numerical thresholds compared to predicate devices.

2. Sample Size Used for the Test Set and Data Provenance:

• Sample Size: The document does not explicitly state the sample size for each performance test. It refers to "testing" that was performed on the PVS 1400 Guidewire, implying a set of units were tested.
• Data Provenance: The data appears to be prospective in nature, as it describes tests specifically conducted on the PVS 1400 Guidewire to compare it to predicate devices. The country of origin for the data is not specified, but the submission is to the US FDA.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications:

Not applicable. This device, being a guidewire, relies on objective physical performance tests rather than expert opinion for its "ground truth" or performance evaluation. The "experts" would be the engineers and technicians conducting the physical tests according to established protocols.

4. Adjudication Method for the Test Set:

Not applicable. The performance evaluation is based on objective measurements and comparisons to predicate devices, not on expert adjudication of subjective assessments.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

No. This type of study (MRMC) is typically used for diagnostic devices (e.g., imaging AI) where human readers interpret cases. The PVS 1400 Guidewire is a physical medical device (guidewire) whose performance is evaluated through bench testing.

6. If a Standalone Study (algorithm only without human-in-the-loop performance) was done:

Yes, in essence. The performance data presented (tip flexibility, tensile strength, torqueability, etc.) are all standalone evaluations of the PVS 1400 Guidewire's physical characteristics, often compared to predicate devices. There is no "algorithm" in the sense of a software-based AI, but the device's inherent performance is tested independently of human intervention during its function in the context of these tests.

7. The Type of Ground Truth Used:

The ground truth used for performance validation is primarily objective physical measurements and comparisons to established predicate devices. For biocompatibility, the ground truth is established by standardized biological tests and their respective pass/fail criteria. For sterilization, the ground truth is the measured residual levels of sterilants compared to specified limits.

8. The Sample Size for the Training Set:

Not applicable. As a physical medical device, there is no "training set" in the context of machine learning or AI. Its design and manufacturing process are refined based on engineering principles and material science, not data training.

9. How the Ground Truth for the Training Set Was Established:

Not applicable for the reasons stated above (no training set for a physical device). The "ground truth" for the device's fundamental design aspects would come from engineering specifications, material properties, and clinical requirements for guidewires.
