The CompanionPort, a Vascular Access Port for Companion Pets

The CompanionPort, is a drug delivery depot, that is placed under the skin during a short surgical procedure. It is identical to vascular access ports used by human oncologists for their human chemotherapy patients. Once placed all that is visible is a 'bump' under the skin. There is no exit site and no part of the CompanionPort is exposed.

The CompanionPort, prevents the poking, prodding and potential failed attempts at finding a peripheral vein, that can be as painful for veterinary patients as it is for human patients. No one, pets included, likes getting 'stuck' with a needle.

The CompanionPort, provides compassionate, safe and reliable access to the central venous system for long-term therapies such as:

CompanionPorts are subcutaneously placed drug delivery depots, perfect for patients requiring repeated access to their vascular system for the delivery of medications & fluids or for repeated blood testing. The CompanionPort is accessed percutaneously with a Huber point needle. Visit our Huber Needles page to learn more.

cport labelledpathway



The infusion pathway is through the Huber point needle inserted into the port septum, into the port chamber and out through the catheter into the vascular system as seen in the diagram. During blood withdrawal, the pathway is reversed.



Once surgically placed during a short and relatvely simple surgical procedure in the back of the patients' neck, all that is seen is a 'bump' under the skin. mistyIt provides a more comfortable way of treating those requiring repeated access to the venous system.

There is no exit site and no part of the CompanionPort is exposed.

CompanionPorts are packaged in kits that include surgical, accessing and maintenance instructions as well as information for the pet owner.

Available in 3 sizes, the CompanionPort is designed for repeated entry into the vascular system or body cavity for drug delivery or withdrawal of blood for sampling or donation in all sizes of companion pets. The CompanionPort must be accessed with a Huber point, non-coring needle using aseptic technique.
