The Access25 Delivery Microcatheter is indicated to assist in the delivery of diagnostic agents, such as contrast media, and therapeutic devices, such as occlusion coils, to the peripheral and neuro vasculature.
The Access25 Delivery Microcatheter (Access25) is a single lumen medical device designed to aid a physician in accessing distal vasculature when used in conjunction with a guide catheter and micro guidewire. The Access25 Delivery Microcatheter is supplied with annealed stainless steel mandrels that can be used to shape the distal tip as desired.
This document pertains to the Access25™ Delivery Microcatheter by Penumbra, Inc. This is a medical device and not an AI/ML powered device, therefore some relevant sections of the query will not be applicable.

2. Sample size used for the test set and the data provenance:
The document does not explicitly state the exact sample sizes (number of devices) used for each individual test. However, it indicates that the tests were conducted on "units" multiple times ("The device was evaluated for torque strength by measuring the number of catheter rotations until failure").
The provenance of the data is from bench performance testing and biocompatibility testing. This typically implies laboratory settings rather than patient data, therefore country of origin and retrospective/prospective distinctions are not directly applicable in the same way they would be for clinical trials.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This is a medical device, not an AI/ML algorithm requiring expert ground truth in the context of image analysis or diagnostic interpretation. The "ground truth" for this device's performance is established through adherence to recognized international standards (e.g., ISO, USP, ANSI/AAMI) and engineering specifications, which are developed and validated by experts in their respective fields (e.g., materials science, medical device design, sterilization, biocompatibility).
4. Adjudication method for the test set:
Not applicable in the context of this device. The testing described is objective performance measurement against pre-defined engineering and biological acceptance criteria, rather than subjective interpretation requiring adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
Not applicable. This is a physical medical device (microcatheter), not an AI-powered diagnostic or assistive tool. Therefore, MRMC studies and the concept of human reader improvement with AI assistance are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
Not applicable. This is a physical medical device.
7. The type of ground truth used:
The "ground truth" for this device's performance is based on established industry standards and regulatory requirements (e.g., ISO 10555-1, ISO 11135-1, ISO 10993 series, USP <151>, ANSI/AAMI ST72) and internal product specifications. These standards and specifications define what constitutes safe and effective performance for such a device.
8. The sample size for the training set:
Not applicable. This is a physical medical device, not an AI/ML algorithm that requires a training set.
9. How the ground truth for the training set was established:
Not applicable. As this is not an AI/ML algorithm, there is no training set or its associated ground truth establishment process. The "ground truth" in the device development context refers to the established performance requirements and standards against which the device is tested.
