072 Aspiration Catheter: As part of the 072 Aspiration System, the 072 Aspiration Catheter with a compatible suction pump is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral - M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA therapy are candidates for treatment.
Aspiration Tubing: As part of the 072 Aspiration System, the Aspiration Tubing is intended to connect the 072 Aspiration Catheter to a compatible suction pump.
The 072 Aspiration Catheter is a single lumen, variable stiffness catheter. The catheter has a hydrophilic coating to reduce friction during use. The catheter includes radiopaque markers on the distal end for angiographic visualization and a Luer hub on the proximal end allowing attachments for flushing and aspiration. The Delivery Tool is an optional accessory for use with the 072 Aspiration Catheter and should be removed prior to aspiration. The 072 Aspiration Catheter, Delivery Tool. Rotating Hemostasis Valve, and Flow Switch are included in the package. The Aspiration Tubing is provided in a separate package. For the aspiration source, the 072 Aspiration Catheter is used in conjunction with a compatible suction pump with prespecified performance parameters that is connected using the Aspiration Tubing.
Here's a breakdown of the acceptance criteria and study information for the Q'Apel Medical, Inc. 072 Aspiration System, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are generally phrased as meeting "predetermined acceptance criteria" or specific ISO standards. The reported device performance for all bench tests and animal studies is "Pass," indicating that all samples met the defined criteria.
Note: For bench tests, specific numerical acceptance criteria are not detailed in the provided summary, only the general statement that "All samples met the predetermined acceptance criteria." For biocompatibility, the specific numerical acceptance criteria are listed.

| Biocompatibility Testing (072 Aspiration Catheter and Delivery Tool) | ||
| Cytotoxicity - MEM Elution | The achievement of a numerical grade greater than 2 is considered a cytotoxic effect. (Implicit acceptance: numerical grade ≤ 2) | Non-cytotoxic |
| Sensitization | Magnusson and Kligman grades of 1 or greater in the test group generally indicate sensitization, provided grades of less than 1 are seen in control animals. If grades of 1 or greater are noted in control animals, then the reactions of test animals which exceed the most severe reaction in control animals are presumed to be due to sensitization. (Implicit acceptance: no statistically significant sensitization compared to control) | Non-sensitizing |
| Irritation: Intracutaneous Reactivity | The requirements of the test were met if the final test article score was ≤ 1.0. | Non-irritating |
| Acute Systemic Toxicity | If using five animals per group, the test article meets the requirement of the test if: 1. Two or more animals from the test group die. 2. Animal behavior, such as convulsions or prostration, occurs in two or more animals from the test group. 3. A final (end of study) body weight loss > 10% occurs in three or more animals from the test group. (Implicit acceptance: none of these conditions occurred) | Non-toxic |
| Material Mediated Pyrogenicity | The requirements of the test were met if no rabbit showed an individual rise in temperature of 0.5 °C or more above its respective baseline temperature throughout the duration of the test. | Non-pyrogenic |
| ASTM Hemolysis- Direct | The positive control's mean hemolytic index above the negative control must be ≥ 5% for the direct method. The negative control must display a mean hemolytic index of |
