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, coil- and braid-reinforced, variable-stiffness catheter designed for neurovascular access. It features a hydrophilic coating on the distal segment for navigation and a radiopaque marker for fluoroscopic visualization. The device is supplied with a rotating hemostasis valve (RHV) and a valve crossing tool. It is used by physicians in a clinical setting to facilitate the insertion and guidance of microcatheters into neurovascular vessels. The RHV maintains hemostasis during the infusion of saline or contrast agents and the insertion of other devices. The catheter is advanced under fluoroscopic guidance using standard percutaneous interventional techniques. By providing a stable access path, the device assists in the delivery of therapeutic or diagnostic microcatheters to target sites within the neurovasculature, potentially benefiting patients by enabling minimally invasive neurointerventional procedures.

Clinical Evidence

No clinical data was deemed necessary to demonstrate substantial equivalence. Evidence is based on bench testing, including dimensional inspection, simulated use, hydrophilic coating integrity, particulate recovery, kink resistance, leakage testing, burst testing, tensile testing, torque strength, and flow rate characterization. Biocompatibility was verified per ISO 10993-1:2018.

Technological Characteristics

Single-lumen, coil- and braid-reinforced catheter; variable stiffness; hydrophilic coating; radiopaque distal marker; 8 Fr profile. Materials include metals and polymers. Sterilized via ethylene oxide (EO). Accessories include RHV and valve crossing tool. Complies with ISO 10555-1:2013 (leakage/integrity) and ISO 10993-1:2018 (biocompatibility).

Indications for Use

Indicated for use in facilitating the insertion and guidance of microcatheters into a selected blood vessel in the neurovasculature.

Regulatory Classification

Identification

## Device Description

The Millipede 088 Access Catheter consists of the catheter, a rotating hemostasis valve (RHV) and a valve crossing tool. The catheter, RHV and valve crossing tool are provided sterile. They are sterilized by ethylene oxide (EO).

The Millipede 088 Access Catheter is a single lumen, coil-reinforced, variable stiffness catheter. The distal segment has a hydrophilic coating for navigation through the vasculature. The catheter has a radiopaque marker located at its distal end for visualization under fluoroscopy. The valve crossing tool is used to open the valve of the access sheath and to facilitate insertion of the Millipede 088 Access Catheter through the access sheath without damage. The RHV is assembled onto the hub of the Millipede 088 Access Catheter and is used to maintain hemostasis during infusion of saline and contrast agent and insertion of other devices through the Millipede 088 Access Catheter.

### Indications for 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.

The Indications for Use statement for the modified Millipede 088 Access Catheter is identical to the predicate device.

### Biocompatibility

The materials, formulation and suppliers of the materials used in the Millipede 088 Access Catheter in the subject and predicate devices are identical. The product-contacting packaging materials in both devices are also identical, therefore no further biocompatibility testing was required for these components of the subject device.

Biocompatibility testing was completed on the accessories provided with the modified Millipede 088 Access Catheter. The Rotating Hemostasis Valve (RHV) and Valve Crossing Tool (VCT) to be provided with the subject device include changes in material and design when compared with those provided with the predicate. The modified accessories were evaluated in accordance with ISO 10993-1:2018. A summary of the biocompatibility testing is outlined below.

| 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. |
| Irritation - ISO Intracutaneous<br>Reactivity | Requirements of the ISO intracutaneous reactivity test<br>were met for the test article. |
| Acute Systemic Toxicity - ISO Acute<br>Systemic Injection | Requirements of the ISO acute systemic injection test<br>were met for the test article. |
| Material-Medicated Pyrogenicity | The test article is non-pyrogenic. |
| Hemocompatibility – ASTM Hemolysis | The test article is considered non-hemolytic. |

#### Shelf Life and Packaging

The labeled shelf life is identical for the subject and predicate devices. The sterile barrier is also identical for the subject and predicate devices. Dimensional changes were made to the protective tube and packaging card to accommodate a longer catheter and modified accessories. Packaging validation testing was completed to assess these changes.

#### Sterilization

The sterilization method is identical for the subject and predicate devices. Confirmatory EO residual testing was repeated on the modified 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 Testing

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

### Clinical Testing

No clinical data was deemed necessary to demonstrate substantial equivalence between the subject and predicate devices.

#### Conclusion

The intended use and indications for use of the Millipede 088 Access Catheter are identical to the intended use and indications for use of the predicate device. The subject modified 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 testing and biocompatibility testing demonstrates that the modified Millipede 088 Access Catheter is substantially equivalent to the predicate device.
