No
The description focuses on mechanical and physical actions (rotational wire, maceration, balloon) and does not mention any computational or learning components. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".
Yes
The device is described as a "Rotational Thrombectomy System" that permits "mechanical declotting and removal of thrombi and emboli" to "restore patency to occluded synthetic dialysis grafts," which indicates a therapeutic purpose.
No
Explanation: The device description and intended use clearly state that the Cleaner II is a treatment device, designed for mechanical declotting and removal of thrombi and emboli, not for diagnostic purposes.
No
The device description explicitly states it is a "battery operated, hand held, wall contacting, rotational thrombectomy device" with a "rotational wire" and "integrated Embolectomy balloon," indicating it is a physical hardware device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that the Rex Medical Cleaner II Rotational Thrombectomy System is a mechanical device used to physically remove thrombi and emboli from synthetic dialysis grafts and the arterial system. It operates within the body (in vivo) rather than on samples outside the body (in vitro).
- Intended Use: The intended use is for mechanical declotting and removal of blockages within the vascular system, not for diagnostic testing of biological samples.
Therefore, this device falls under the category of a medical device used for treatment, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Rex Medical Cleaner II Rotational Thrombectomy System permits mechanical declotting and removal of thrombi and emboli in synthetic dialysis grafts. The Embolectomy balloon component, located on the Cleaner II Device, may be used for subsequent Embolectomy procedures to remove emboli and thrombi in the arterial system communicating with the synthetic dialysis graft.

Device Description
The Rex Medical Cleaner II Rotational Thrombectomy System is a battery operated, hand held, wall contacting, rotational thrombectomy device which provides an effective means to restore patency to occluded synthetic dialysis grafts. The rotational wire, with integrated soft distal tip, provides an atraumatic approach to mechanical thrombectomy. The Cleaner II macerates clot into particulate size that is not harmful to the patient. The integrated Embolectomy balloon provides a means to remove macerated thrombi, as well as wall adherent thrombi, from the dialysis graft. If required, the Embolectomy balloon located on the Cleaner II device may be used to remove any additional thrombi or emboli from the patient after the initial thrombectomy procedure has been performed.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing included: Stall Torque Test, Tensile Test, Valve Compression Test, Contrast Infusion Test, Wire Fatigue Test, Clot Maceration in Graft, Dimensional Analysis of Balloon Catheter, Balloon Leakage and Damage (Per ISO 10555-4). Testing proved that the Rex Medical Cleaner II device is as safe and effective as the predicate devices. Statistical sampling rationale for choosing the number of devices that were tested was based on ISO 2859-1 sampling plans in accordance with our projected lots (batch) size. Testing results revealed that the Rex Medical Cleaner II Rotational Thrombectomy System device is substantially equivalent to the predicate devices.

5. Device Description:
The Rex Medical Cleaner II Rotational Thrombectorny System is a battery operated, hand held, wall contacting, rotational thrombectorny device which provides an effective means to restore patency to occluded synthetic dialysis grafts. The rotational wire, with integrated soft distal tip, provides an atraumatic approach to mechanical thrombectorny. The Cleaner II macerates clot into particulate size that is not harmful to the patient. The integrated Embolectorny balloon provides a means to remove macerated thrombi, as well as wall adherent thrombi, from the dialysis graft. If required, the Embolectomy balloon located on the Cleaner II device may be used to remove any additional thrombi or emboli from the patient after the initial thrombectorny procedure has been performed,
6. Intended Use:
The Rex Medical Cleaner II Rotational Thrombectomy System permits mechanical declotting and removal of thrombi and emboli in synthetic dialysis grafts. The Embolectory balloon component, located on the Cleaner II Device, may be used for subsequent Embolectomy procedures to remove emboli and thrombi in the arterial system communicating with the synthetic dialysis graft
7. Comparison to Predicate Devices:
The Cleaner II device has the same technological features as the predicate devices.
The following testing was performed to prove substantial equivalence of the Rex Medical Cleaner II Rotational Thrombectomy Device to the predicate devices:
| Stall Torque Test |
|---|
| Tensile Test |
| Valve Compression Test |
| Contrast Infusion Test |
| Wire Fatigue Test |
| Clot Maceration in Graft |
| Dimensional Analysis of Balloon |
| Catheter |
| Balloon Leakage and Damage |
| (Per ISO 10555-4) |

Testing proved that the Rex Medical Cleaner II device is as safe and effective as the predicate devices.
8. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows:
Performance testing, which includes testing protocols, testing results and conclusions, were based on ISO 10555-1, ISO 10555-4, and FDA's "Guidance on Pre-market Notification (510(k)) Submission for Short-Term and Long-Term Intravascular Catheters", was submitted with this submission.
Statistical sampling rationale for choosing the number of devices that were tested was based on ISO 2859-1 sampling plans in accordance with our projected lots (batch) size.
Testing results revealed that the Rex Medical Cleaner II Rotational Thrombectorny System device is substantially equivalent to the predicate devices.
். Conclusions:
The subject device, Rex Medical Cleaner II Rotational Thrombectorny System, has the same intended use as the predicate devices. Moreover, bench testing contained in our submission and the non-clinical testing supplied demonstrates that there are no differences in their technological characteristics, thereby not raising any new questions of safety or effectiveness. Thus, the Rex Medical Cleaner II Rotational Thrombectomy System is substantially equivalent to the predicate devices.
