The summary describes a mechanical thrombectomy device that uses a saline stream to remove thrombus. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies focus on clinical trial results comparing the device to existing therapies, not on the performance of an AI/ML algorithm.
Yes
The device is designed to treat thrombosed hemodialysis access grafts by removing thrombus, which is a therapeutic intervention.
No
The device is described as a "mechanical thrombectomy device" designed to "remove thrombus." Its function is therapeutic (to remove clots), not diagnostic (to identify or analyze a condition).
No
The device description clearly outlines a physical catheter with lumens and a guidewire, indicating it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Oasis Thrombectomy System function: The description clearly states that the Oasis Thrombectomy System is a percutaneous, mechanical device used to remove thrombus from within hemodialysis access grafts. This is an in vivo procedure, meaning it's performed inside the body.
The device is a therapeutic device used for a medical procedure, not a diagnostic test performed on a sample.
N/A
Intended Use / Indications for Use
The Oasis Thrombectomy System is a percutaneous, hydrodynamic, mechanical thrombectomy device designed for use with standard angiographic injectors. The catheter uses a high velocity saline stream to microfragment and remove thrombus from hemodialysis access grafts.

Device Description
The catheter features an outer shaft and is comprised of three: an inflow lumen to supply saline to the catheter tip, an outflow lumen for removal of thrombotic material and a guidewire lumen to accommodate an 0.018 inch guidewire. The catheter is 6F in diameter and is available in soft and braided configurations.

| Device Generic Name: | Thrombectomy Catheter |
| Device Classification: | 74 DXE, Catheter Embolectomy |
B. INDICATIONS FOR USE
The Oasis Thrombectomy System is a percutaneous, hydrodynamic, mechanical thrombectomy device designed for use with standard angiographic injectors. The catheter uses a high velocity saline stream to microfragment and remove thrombus from hemodialysis access grafts.
C. DESCRIPTIVE CHARACTERISTICS
The catheter features an outer shaft and is comprised of three: an inflow lumen to supply saline to the catheter tip, an outflow lumen for removal of thrombotic material and a guidewire lumen to accommodate an 0.018 inch guidewire. The catheter is 6F in diameter and is available in soft and braided configurations.
D. SUBSTANTIAL EQUIVALENCE
The subject thrombectomy catheter has been shown to be substantially equivalent to the Fogarty Embolectomy Balloon Catheter and Microvena's 8F Clot Buster Amplatz Thrombectomy Catheter. Results from a randomized, prospective clinical trial established that the proposed thrombectomy catheter is safe and effective for treatment of thrombosed hemodialysis grafts when compared to pulsed spray thrombolytic therapy.
E. PACKAGING, STERILIZATION, AND PYROGENICITY
The catheter is packaged in a heat-sealed Tyvek/mylar pouch. The product is sterilized using ethylene oxide gas. Boston Scientific monitors bacterial endotoxins on product on a monthly basis.
F. CONCLUSION
Based on the information presented, Boston Scientific Corporation believes that the thrombectomy catheter meets the minimum requirements that are considered acceptable for its intended use and is substantially equivalent to other currently thrombectomy catheters.

Dear Ms. Mondano:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). You may, therefore, market the device, subject to the qeneral controls provisions of the Act. However, you are responsible to determine that the medical devices you use as components in the [kit/tray] have either been determined as substantially equivalent under the premarket notification process (Section 510(k) of the act), or were legally on the market prior to May 28, 1976, the enactment date of the Medical Device Amendments. Please note: If you purchase your device components in bulk (i.e., unfinished) and further process (e.g., sterilize) you must submit a new 510(k) before including these components in your kit/tray. The general controls provisions of the Act include requirements for annual registration, listinq of devices, qood manufacturing practice, and labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such
