The Circuport™ System features an implantable port for direct access to the vessel, and a frame that prevents the compression of blood vessels during access with the specially designed dialysis needle.

Two such ports are implanted in each patient. One port is sutured to an artery, and the other to a vein. An anti-compression frame is assembled around each port and vessel and completely covered by the skin. The final assembly provides direct, sterile, durable and quick access into the patient’s blood stream.

Unlike existing systems, the artery and vein to be used for The Circuport™ System do not need to be in close proximity to each other. This not only presents many new possibilities for patients who have run out of suitable sites for current access systems, but is also expected to improve the efficiency of the hemodialysis process by eliminating blood admixture (the mingling of filtered and unfiltered blood) that can occur when the blood is removed from and returned to sites that are very close to each other in the same blood vessel, prevents squeezing the artery or vein during the insertion of the needle. As an added safeguard, the specialized needles allow the healthcare practitioner to insert the needle to the appropriate safe depth every time.

Perhaps most importantly, The Circuport™ System prevents the inevitable damage to the blood vessel wall which results from puncturing an artery or a vein with a sharp needle, several times a week.

By providing a sturdy access point, made of silicone which is protected with a titanium casing, the potential for damage to the arterial wall during the process of needle puncture is greatly reduced.

This critical part of the Circuport™ port has demonstrated durability equivalent to two years of hemodialysis.

The Circuport™ System is easy to implant using common vascular surgical techniques and is no harder to implant than existing access systems. It is expected that a vascular surgeon will be able to implant a pair of ports in approximately an hour. The ports have been designed to last for two years for a typical dialysis patient receiving treatment three times per week.

While the core part of the port prevents damage to the arterial wall, since the needle never penetrates the artery or the PTFE patch, the anti-compression frame prevents squeezing the artery or vein during the insertion of the needle. As an added safeguard, the specialized needles allow the healthcare practitioner to insert the needle to the appropriate safe depth every time. 

The Circuport™ System is designed to provide a new direction for dialysis with the goal of reducing the risks of arterial damage, cardiac overload, vessel thrombosis and infection.
