Intended Use

The Millipede 088 Access Catheter is indicated for use in facilitating the insertion and guidance of microcatheters into a selected blood vessel in the neurovasculature.

Device Story

The Millipede 088 Access Catheter is a single-lumen, variable-stiffness, wire-reinforced catheter designed for neurovascular access. It is used by physicians in clinical settings to facilitate the delivery of microcatheters. The device features a hydrophilic coating on the distal segment for navigation and a radiopaque marker for fluoroscopic visualization. It is supplied with a rotating hemostasis valve (RHV) to maintain hemostasis during saline/contrast infusion and device insertion, and a valve crossing tool to protect the valve during catheter introduction. The catheter is advanced percutaneously under fluoroscopic guidance. By providing a stable conduit, it assists in accessing target neurovasculature, potentially benefiting patients by enabling minimally invasive interventional procedures.

Clinical Evidence

No clinical data was conducted. Substantial equivalence is supported by bench testing, including dimensional inspection, simulated use, hydrophilic coating integrity, particulate recovery, kink resistance, tip stiffness, leakage (ISO 10555-1), tensile strength, torque strength, and flow rate characterization. Biocompatibility was verified per ISO 10993-1:2018.

Technological Characteristics

Single-lumen, variable-stiffness, coil/braid-reinforced catheter. Materials: metals and polymers. Distal tip: soft/flexible with hydrophilic coating. Dimensions: 8 Fr profile, 0.088" inner diameter. Sterilization: Ethylene Oxide (EO) per ISO 10993-7. Shelf life: 12 months (verified via ASTM F1980).

Indications for Use

Indicated for facilitating insertion and guidance of microcatheters into selected blood vessels in the neurovasculature.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

### Biocompatibility

The subject device includes some material differences compared to the predicate device. To ensure that all new materials were assessed, relevant biocompatibility endpoints were addressed through biocompatibility testing of the subject Millipede 088 Access Catheter. The testing was completed in accordance with ISO 10993-1:2018. The table below summarizes the biocompatibility testing completed.

| Test | Results |
|-------------------------------------------------------------------|------------------------------------------------------------------------------------------------|
| Cytotoxicity - ISO MEM Elution | The test article is non-cytotoxic. |
| Sensitization – ISO Guinea Pig<br>Maximization Sensitization Test | The test article did not elicit a sensitization response. |

### Shelf Life and Packaging

The subject device has a labeled shelf life of 12 months, compared to 8 months for the predicate device. Device performance was verified by functional and performance testing after 12-month accelerated aging according to ASTM F1980.

Packaging validation for the predicate device included testing on units subjected to accelerated aging to simulate a 12-month shelf life as per ASTM F1980. This was used to support the labelled 8-month shelf life for the predicate device. The packaging is identical for the subject and predicate devices. Therefore, the original packaging testing for the predicate device remains valid and supports the subject device's 12-month shelf life. No further packaging testing is required for the subject device.

### Sterilization

The sterilization method is identical for the subject and predicate devices. Confirmatory EO residual testing was repeated on the subject Millipede 088 Access Catheter to confirm that the design differences did not impact residual EO levels of the testing confirmed that EO residuals were within the limits specified in ISO 10993-7.

### Animal Study

No animal study was deemed necessary to demonstrate substantial equivalence between the subject and predicate devices.

### Clinical Data

The non-clinical performance data presented were determined to be sufficient to support the substantial equivalence of the subject and predicate devices. Therefore, no clinical study was conducted.

{7}------------------------------------------------

### Conclusion

The indications for use of the Millipede 088 Access Catheter are identical to the predicate device. The subject Millipede 088 Access Catheter and the predicate device use the same operating principles and have a similar design. The differences identified in this submission do not raise different or new questions of safety or effectiveness. The successful completion of performance and biocompatibility testing demonstrates that the subject Millipede 088 Access Catheter is substantially equivalent to the predicate device.
