The Alviguide™ Blue+ Interventional Cardiology Guiding Catheter is intended for use in the intravascular introduction of interventional/diagnostic devices into the coronary vascular system.
The Alguide™ Endovascular Guiding Catheter is intended for use in the intravascular introduction of interventional/ diagnostic devices into the peripheral vascular system.
The Alviguide™ Blue+ and Alguide™ Guide Catheters are sterile, non-pyrogenic, single lumen catheters with a tri-layer catheter body construction consisting of a polymer inner layer and a radiopaque outer layer surrounding a stainless steel wire braid, and a soft tip at the distal end. The catheters are for single-use only.
The Alviguide™ Blue+ and Alguide™ Guide Catheters are provided in a variety of distal shape configurations and are available in Fr Sizes 5, 6, 7 and 8 and lengths of 45, 60, 65 and 80cm (Alguide™), and 100cm (Alviguide™ Blue+ and Alguide™).
The provided text describes the 510(k) premarket notification for two guiding catheters and lists the testing performed to demonstrate substantial equivalence to predicate devices. However, it does not contain information about the acceptance criteria for a device's performance in a study, nor does it detail a study that proves the device meets specific acceptance criteria in the context of an AI/algorithm-based medical device.
The document focuses on:
- Device Description: Alviguide™ Blue+ Interventional Cardiology Guiding Catheter and Alguide™ Endovascular Guiding Catheter.
- Intended Use: Intravascular introduction of interventional/diagnostic devices into the coronary/peripheral vascular system.
- Substantial Equivalence: Comparison to predicate devices based on similar indications for use, design, materials, and nonclinical (bench) and biocompatibility testing.
The "testing in support of substantial equivalence determination" section lists various bench tests and biocompatibility tests, but these are focused on the physical and biological properties of the catheter itself, not on the performance of a diagnostic algorithm or AI system. There is no mention of "acceptance criteria" for a study in the sense of accuracy, sensitivity, specificity, or performance thresholds for an AI.
Therefore, I cannot fulfill the request to provide a table of acceptance criteria and reported device performance or details about an AI-driven study from the provided text. The document pertains to a physical medical device (catheter), not an AI/software-as-a-medical-device (SaMD).

ASAHI ZenyteEX Guiding Catheter is intended for use in coronary or peripheral vascular applications and is designed to provide a pathway through which medical instruments, such as balloon catheters, guide wires or other therapeutic devices may be introduced. This device is not intended for use in the cerebral vasculature.
The ASAHI ZenyteEX Guiding Catheter is intended for use in coronary or peripheral vascular applications and is designed to provide a pathway through which medical instruments, such as balloon catheters, guide wires or other therapeutic devices may be introduced. The Catheter consists of a tube, which is to be inserted into vasculature, a proximal hub/connector, and strain relief/protector for the joint portion of the first 2 sections. The tube body section consists of soft tip, soft tube and shaft. The tube body itself is constructed of a polyamide elastomer. The shaft is reinforced by stainless steel braid, and it consists of two layers. The distal portion of the tube is made soft in order to easily bend.
The provided text is a 510(k) summary for a medical device called the ASAHI ZenyteEX Guiding Catheter. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a study with specific acceptance criteria and performance metrics in the way that would typically be done for a novel AI/software device.
Therefore, much of the requested information (such as sample sizes for test/training sets, number of experts, adjudication methods, MRMC studies, standalone performance for an algorithm, and ground truth establishment for a training set) is not applicable to this type of device submission as described in the provided document.
However, I can extract the relevant information regarding acceptance criteria and the type of study performed to show the device meets these criteria.
Acceptance Criteria and Device Performance for ASAHI ZenyteEX Guiding Catheter
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria Category | Specific Criteria/Tests Performed | Reported Device Performance |
|---|---|---|
| Biocompatibility | Compatibility with patient contact (materials) | "All components that come in direct contact with the patient have a long history of use in medical devices and are proven to be biocompatible for use in the vasculature. Furthermore, this submission contains biocompatibility testing conducted on the subject device." (Implies successful completion.) |
| Technical/Dimensional | Dimensional specifications equivalence to predicate devices | "The dimensional specifications are equivalent to those listed for the currently cleared predicate devices." |
| Material Composition | Use of same materials as predicate devices | "The ASAHI ZenyteEX Guiding Catheter is made of the same materials that have been used in other predicate devices that are labeled for the similar indications." |
| Functional Performance | Mechanical and Functional Bench Testing | "This 510(k) notice also includes mechanical and functional bench testing that demonstrates that the ASAHI ZenyteEX Guiding Catheter performs as intended." (Implies successful performance.) |
| Substantial Equivalence | Equivalence to specified predicate devices for same indication for use | "The ASAHI ZenyteEX Guiding Catheter characteristics are substantially equivalent to the specified predicate devices and other currently marketed devices for the same indication for use." |
| Intended Use | Ability to provide a pathway for medical instruments | "Bench testing demonstrates that the device functions as intended." (Supports the intended use.) |
2. Sample Sizes Used for the Test Set and Data Provenance
Not applicable. This is a physical medical device (guiding catheter), not a software or AI device requiring a "test set" of data. The "testing" refers to physical and material testing. The document does not specify sample sizes (e.g., number of catheters tested) for the mechanical, functional, or biocompatibility bench tests. Data provenance is also not applicable in the context of data for an AI/software device; the provenance here would be the manufacturing site (Japan).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. As this is a physical device, there is no "ground truth" in the context of expert review of data. Performance is evaluated via engineering, material, and biocompatibility testing.
4. Adjudication Method for the Test Set
Not applicable. There is no "adjudication method" as would be used for diagnostic output from an AI/software device. Performance is determined by meeting pre-defined physical and chemical specifications.
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, not an AI/software diagnostic aid.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device, not an algorithm.
7. The Type of Ground Truth Used
Not applicable in the context of expert consensus, pathology, or outcomes data. For a physical device like this, the "ground truth" for performance is established through adherence to engineering specifications, material properties, and regulatory standards demonstrated via bench testing.
8. The Sample Size for the Training Set
Not applicable. This is a physical medical device, not an AI/software device that requires a training set.
9. How the Ground Truth for the Training Set was Established
Not applicable. This is a physical medical device, not an AI/software device that requires a training set.
