Abstract
A vascular access tube (2) for a fluid subject to a driving pressure comprises a wall (4) defining a main lumen. A portion of the wall comprises an access port (10) for an object (14) to be introduced through the wall. The access port comprises a biasing structure (12) which provides a self-closing behaviour that is sufficiently strong to remain fluid-tight when exposed to a driving pressure of up to 50 mmHg. The access port is therefore sufficiently fluid-tight to contain pressurised fluid flowing through the vascular access tube.
Claims25
An arterial access graft for blood subject to a driving pressure, the arterial access graft being configured for surgical attachment to an axillary artery and for providing access to the axillary artery via an access port, the arterial access graft comprising a wall defining a main lumen, wherein a portion of the wall comprises the access port into the graft through the wall, wherein the access port comprises a biasing structure providing a self-closing behaviour sufficiently strong to remain fluid-tight when exposed to a driving pressure of up to 50 mmHg (0.0658 atm) or higher, whereby the access port is sufficiently fluid-tight to contain pressurised blood flowing through the arterial access graft.
