Indications for Use
The Esperance Aspiration Catheter with the Medela Dominant Flex Surgical Suction Pump and Wallaby Aspiration Tubing set is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within 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) or who fail IV t-PA therapy are candidates for treatment.
Device Story
Esperance Aspiration Catheter System is a single-use, variable stiffness, composite vascular catheter (5F and 6F sizes). Used in neurointerventional procedures to revascularize occluded intracranial vessels via aspiration. Device is advanced through vasculature to the occlusion site; connected to an external Medela Dominant Flex Surgical Suction Pump via Wallaby Aspiration Tubing. Aspiration removes thrombus, restoring blood flow. Operated by physicians in clinical settings. Distal tip is radiopaque for fluoroscopic visualization; hydrophilic coating reduces friction. System includes shaping mandrel and peelable sheath. Output is the physical removal of the clot, directly impacting clinical decision-making by enabling mechanical thrombectomy in stroke patients.
Clinical Evidence
No clinical data. Substantial equivalence established via non-clinical bench testing (dimensional, aspiration rate, simulated use, tensile, torque, kink resistance, vacuum resistance) and animal studies (porcine model, 3- and 30-day sub-chronic/chronic, gross necropsy, histopathology) comparing 6F Esperance to Penumbra ACE 68.
Technological Characteristics
Single-lumen composite catheter; 5F (0.055" ID) and 6F (0.071" ID). Materials: Tecothane, Pebax, Vestamid, PTFE, Nitinol coil/braid. Hydrophilic coating. Radiopaque Pt/Ir marker band. Sterilized via Ethylene Oxide (ISO 11135). Luer hub per ISO 80369-7. Non-active, surgically invasive.
Indications for Use
Indicated for patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (internal carotid, middle cerebral M1/M2, basilar, vertebral arteries) within 8 hours of symptom onset. Candidates include those ineligible for or failing IV t-PA therapy.
Regulatory Classification

Dear Nathaniel Knock:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
{1}------------------------------------------------
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

## a. Device Description
The Esperance Aspiration Catheter System is a single-use, vascular catheter consisting of a single lumen, variable stiffness, composite catheter. The device system includes 5F and 6F catheters with inner diameters of 0.055" and 0.071", respectively, designed with three different working lengths for both sizes: 115 cm, 125 cm, and 131 cm. The device is supplied as a kit with Wallaby Aspiration Tubing Set provided with a single catheter. The distal tip of each catheter is visible under fluoroscopy and the distal shaft of each catheter is designed with an external hydrophilic coating to reduce friction during use. The proximal end of each catheter incorporates a strain relief and a standard Luer adapter to facilitate the attachment of accessories. Each catheter has a semi-rigid proximal shaft which transitions into a flexible distal shaft to facilitate the advancement of the catheter in tortuous anatomy.
The Esperance Aspiration Catheter System is a non-active, surgically invasive device intended for short term use within the vasculature.
## b. Indication for Use
The Esperance Aspiration Catheter with the Medela Dominant Flex Surgical Suction Pump and Wallaby Aspiration Tubing set is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within 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) or who fail IV t-PA therapy are candidates for treatment.
