The device description explicitly lists physical components such as an introducer sheath, a stainless steel anti-clogging/self-cleaning unit, and suction components, indicating it is a hardware-based medical device.
Based on the provided information, the Gelbfish Endo-Vac System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for the percutaneous aspiration of thrombus from acutely clotted AV grafts as part of a percutaneous thrombectomy procedure. This is a surgical/interventional procedure performed directly on the patient's body.
- Device Description: The device components are instruments used for a medical procedure (sheath, dilator, guidewire, suction components, etc.).
- Lack of In Vitro Activity: IVD devices are intended for the examination of specimens derived from the human body in vitro (outside the body) to provide information for diagnostic, monitoring, or compatibility purposes. The Gelbfish Endo-Vac System is used in vivo (inside the body) to remove material.
Therefore, the Gelbfish Endo-Vac System is a medical device used for an interventional procedure, not an in vitro diagnostic device.

LEGALLY MARKETED PREDICATE DEVICES A.
The Gelbfish EndoVac System is substantially equivalent to two preamendment devices, both endovascular suction catheters, marketed in the 1960s by the A. S. Aloe Company, St. Louis, MO, and by the Klista Company, Nashville, TN. These devices were used in general vascular surgery applications where it was necessary to remove thrombus. It is also similar to another pre-amendments suction thrombectomy device that is still marketed today by Medi-tech, the Greenfield Pulmonary Embolectomy Catheter which uses a suction mechanism for the extraction of clot from the pulmonary vasculature.

INDICATIONS FOR USE C.
The Gelbfish EndoVac System is intended for the percutaneous aspiration of thrombus from acutely clotted AV grafts as a part of a percutaneous thrombectomy procedure. The device incorporates an anticlogging/self-cleaning mechanism to maintain its uninterrupted function.
The device is not (by itself) intended to restore function to clotted AV grafts. It is only used in conjunction with standard percutaneous thrombectomy procedures to facilitate the aspiration of clot from the graft. The arterial and venous anastomotic plug/clot and pathology must still be addressed by standard Fogarty and/or balloon catheter procedures. Expertise in traditional pharmoco-mechanical techniques is necessary, and may be used in conjunction with the EndoVac System.
The enclosed device is indicated for use to remove thrombus in clotted synthetic ePTFE grafts only. Its short length makes it suitable for aspiration of clot from the body of the graft. It is NOT intended to cross arterial or venous anastomoses or to be used on clot contained in native artery or vein.
TECHNOLOGICAL CHARACTERISTICS D.
The percutaneous thrombectomy procedure in which the EndoVac device is used involves a series of steps, almost all of which are already part of both the radiological and surgical procedures. The only enhancement is the aspiration of clot from the graft via the introducer sheath in conjunction with the anti-clogging/self-cleaning mechanism.
The anti-clogging/self-cleaning mechanism consists of a blunt tip of the same diameter as the tip of the sheath, a short half-cylindrical tube of the same diameter as the tip, and a 22-gauge tube to inject saline just behind the tip and to provide the mechanical movement of the tip. When the tip is extended just beyond the end of the sheath, the half-cylindrical tube allows thrombus to be sucked into the sheath through its open half. When thrombus clogs the sheath during suction, the tip is withdrawn into the sheath, cutting off the interior of the sheath from the clotted graft. Saline is introduced inside the tip behind the clog and allows the sheath to be cleared, after which the tip is again extended into the open position and aspiration continues.
Clinical procedure: An introducer sheath is inserted in the venous limb of the graft pointing towards the venous anastomosis. The sideport is connected to wall suction controlled via a hand held valve. The sheath with self-cleaning mechanism is inserted into the graft, suction is
2
activated and the sheath is slowly pulled back, reciprocating the selfcleaning mechanism and with active irrigation as necessary.
TESTING E.
Mechanical testing has demonstrated that the stainless steel cleaning mechanism, which is laser welded together, can withstand a pull test of 20 lbs.
A clinical study of the device showed that in 47/47 thrombectorny procedures, the EndoVac device successfully cleared thrombus from the araft. The study also demonstrated that the EndoVac device does not interfere in any way with the use of the other instruments and techniques which are required to complete the interventional radiology thrombectorny procedure.
CONCLUSIONS F.
The Gelbfish EndoVac System has the same intended use, notably the aspiration of clot, as the predicate devices. Dr. Gelbfish has demonstrated through his clinical study on the device and his comparison of the device's characteristics with those of the predicate devices that it is substantially equivalent to the predicate devices.
