Patent ID: 7828781

Claim:
An implantable access port adapted to be attached to a blood vessel comprising: a port core comprising a hollow port core casing with an aperture extending therethrough and a patch attached with an interior surface of the port core casing, the patch extending out of the aperture so that the patch can be sutured to the blood vessel, the port core further comprising a self-sealing insert disposed within the aperture and sized to substantially fill the aperture, the insert configured to prevent fluid from flowing through the aperture and also allows penetration by a needle; and a port outer casing comprising a first outer port casing and a second outer port casing adapted to be mated together around the port core when the port core is sutured to the blood vessel, wherein the second outer port casing comprises an adjustable anti-vessel-compression mechanism, the mechanism comprising a movable element having an interior surface that is adapted to partially surround the blood vessel, the movable element being movable in an upwards and downwards direction along the second outer port casing such that when the port core is sutured to the blood vessel and the port outer casing is disposed around the port core, the mechanism can be manipulated such that the interior surface partially surrounds the blood vessel and cups the blood vessel such that the blood vessel is protected from being compressed.
