The XO Score LP Percutaneous Transluminal Angioplasty Scoring Catheter is intended to be used in conjunction with a PTA balloon to facilitate dilation and apposition of the scoring surface to the stenotic material in the iliac, femoral, iliofemoral, popliteal, infra-popliteal, and renal arteries, and for treatment of obstructive lessions of native or synthetic arteriovenous dialysis fistulae. Not for use in the coronary or neuro-vasculature.
The XO Score LP (Low Profile) Percutaneous Transluminal Angioplasty Scoring Catheter is a 2.2 Fr (0.76 mm) and 3.8 Fr (1.27 mm) diameter, single-lumen, metal alloy shaft, a proximal polymer outer jacket and a balloon expandable scoring element at the distal tip. Designed to work with a standard PTA balloon catheter. The XO Score LP catheter essentially adds the lesion scoring / cutting capability to a standard PTA balloon catheter with the scoring element at its distal end. It is available in the one catheter length (150 cm), and longitudinal scoring element length (23cm).
The provided text is a 510(k) summary for the XO Score LP Percutaneous Transluminal Angioplasty Scoring Catheter. It focuses on demonstrating substantial equivalence to a predicate device through comparative analysis and functional/safety testing, rather than an AI-driven medical device requiring a study with acceptance criteria for a new clinical indication or improved diagnostic performance.
Therefore, the document does not contain the information requested regarding acceptance criteria related to device performance in a clinical or diagnostic context, a study proving the device meets that criteria, sample sizes for test/training sets, expert involvement, adjudication methods, MRMC studies, standalone performance, or ground truth establishment relevant to an AI/diagnostic device.
The "acceptance criteria" referred to in the document are for bench testing to validate and verify that the device is substantially equivalent to a predicate device, focusing on physical and functional characteristics of the catheter. This is different from the type of acceptance criteria and study design you're asking for, which typically apply to AI/software as a medical device (SaMD) or diagnostic devices that provide clinical information or assist human readers.
To be specific, the document explicitly states:
"The following testing was conducted to validate and verify that the subject device was substantially equivalent to the predicate devices. All data met pre-determined acceptance criteria."
The listed tests are all bench tests (e.g., Biocompatibility, Kink Radius, Tensile Testing, Retrieval Force Testing, Device Recovery, Accessory PTA Balloon Catheter burst pressure, Torque, Cycling, Scoring Capability Assessment).
In summary, the provided text does not describe the type of study and acceptance criteria you've requested for an AI-driven or diagnostic device.
