Vascular access device and method

The present disclosure concerns a vascular access device (1) comprising a vascular access tube (2), such as a cannula, having a distal end region (3) terminating in a tip (4) for insertion into a blood vessel (V) of a patient and at least one lumen (5) for infusing a medicament and/or for introducing one or more catheters there-through into the blood vessel (V). The device (1) further comprises a fixation mechanism (10) that is operable to secure or fix the distal end region (3) of the vascular access tube (2) with respect to the patient to inhibit or prevent withdrawal of the tip (4) from the blood vessel (V) and/or to inhibit or prevent over-insertion of the tip (4) into the blood vessel (V). The tip (4) of the vascular access tube (2) has an opening (6) for communication between the at least one lumen (5) of the access tube (2) and the blood vessel (V) of the patient into which the tip (4) is inserted, and the fixation mechanism (10) is desirably configured to position and fix the opening (6) of the tip (4) at or adjacent a wall (W) of the blood vessel (V) at a point of insertion of the tip (4). The fixation mechanism (10) is preferably configured to secure or fix the vascular access tube such that the access tube extends longitudinally at a predetermined angle (θ) with respect to the blood vessel (V) at a point of insertion of the tip (4). The predetermined angle (θ) may be within the range of about 20 degrees to about 90 degrees. The disclosure provides a corresponding method of implanting the vascular access device (1) in a patient.
