The Recana Thrombectomy Catheter System is indicated for:

• The non-surgical removal of thrombi and emboli from veins.
• Injection, infusion, and/or aspiration of contrast media and other fluids into or from a vein.

The Recana Thrombectomy Catheter System is indicated for use in peripheral venous vasculature.

The Recana Thrombectomy Catheter System is designed to remove thrombus and emboli from native vessels or stented veins. The system is comprised of the debulking catheter, collection basket(s) with delivery sheaths, and a family of sheaths. Together, the Recana Thrombectomy Catheter System functions to capture and remove obstructive / occlusive thrombus from the venous vasculature.

The debulking catheter utilizes an adjustable diameter stainless steel coring element to remove thrombus from the venous vasculature. Handle controls enable expansion and collapse of the coring element to achieve the desired working diameter. The debulking catheter is 0.035" guidewire and 0.060" basket shaft compatible and provides a working length of 80cm.

18mm and 30mm Collection basket(s) are self-expanding nitinol wire-form and braided structures designed to ensure capture and removal of thrombi and emboli. The basket shaft has a 0.035" guidewire compatible lumen for over the wire delivery through a 9Fr Delivery Sheath with a working length of 95cm.

Sheaths for introduction of the debulking catheter and collection baskets into the vasculature and for the recapture and removal of thrombi and emboli via the collection basket(s) are offered in four (4) size configurations (13Fr x 30cm, 13Fr x 90cm, 16Fr x 30cm, and 16Fr x 90cm) providing optionality based on access vessel size and location.

The provided text is a 510(k) Premarket Notification for the DASH 6® NRFit System, which includes syringes and various accessories. This document primarily focuses on demonstrating substantial equivalence to predicate devices through design verification and compliance with specific ISO standards. It does not describe an AI medical device or a study involving human readers or AI assistance. Therefore, I cannot provide information on acceptance criteria and a study that proves the device meets those criteria in the context of AI performance, MRMC studies, standalone algorithm performance, number of experts, or ground truth for AI model development.

However, I can extract the acceptance criteria and the type of study conducted to demonstrate the device's technical specifications and substantial equivalence, as presented in the document:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the DASH 6® NRFit System are primarily defined by compliance with several ISO standards. The studies conducted were design verification tests demonstrating compliance with these standards.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document describes bench testing for physical characteristics, dimensional verification, and biocompatibility, not a clinical study with a "test set" in the context of AI or diagnostic performance. Therefore, typical sample size or data provenance details for medical image analysis are not applicable. The testing was conducted to verify compliance with engineering standards (ISO standards). The document does not specify the exact number of units tested for each specific test, but mentions "All necessary bench testing was conducted."

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable as the device is a physical medical device (syringes, needles, etc.) and its performance is evaluated against engineering and biological standards, not diagnostic interpretations from experts. Ground truth is established by objective measurements against specified engineering and material science criteria.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This device is not an AI diagnostic tool and does not involve human adjudication of results in the traditional sense of a clinical study or image interpretation.

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. The DASH 6® NRFit System is a medical device (syringes, needles, etc.) and not an AI-powered diagnostic or assistive tool.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This device is not an algorithm or AI system. Its performance is evaluated intrinsically based on its physical properties and adherence to manufacturing and safety standards.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for this device's evaluation is primarily the specifications and requirements defined by international standards (e.g., ISO 80369-6, ISO 7886-1, ISO 10993 series) and the manufacturer's own design specifications. It is based on objective, quantifiable physical and chemical measurements (e.g., fluid leakage, dimensions, material compatibility).

8. The sample size for the training set

Not applicable. There is no "training set" as this is a physical medical device, not a machine learning model.

9. How the ground truth for the training set was established

Not applicable.
