1. A vascular access port configured to be implanted subcutaneously, the vascular access port comprising:

  • a base that extends in a longitudinal direction and in a transverse direction, wherein the base is configured to be bowed in the transverse direction when the vascular access port is attached to a vessel so as to conform to a contour of a wall of a vessel, and wherein the longitudinal direction of the base is configured to run substantially parallel to a lumen of the vessel when the vascular access port is attached to the vessel;

    a guidance passageway that extends through the vascular access port and defines an opening in the base, wherein the guidance passageway comprises a funnel region that decreases in size toward a channel and is rearward of the channel, wherein a central axis that extends through the guidance passageway defines an acute angle relative to a longitudinal length of the base, and wherein the acute angle points in a forward direction toward a front end of the vascular access port; and

    an ingrowth-inducing covering on the base, wherein at least a portion of the ingrowth-inducing covering is between the opening of the guidance passageway and the front end of the vascular access port, and wherein the ingrowth-inducing covering is configured to promote attachment of the vascular access port to a vessel so as to maintain the opening of the guidance passageway at a fixed position relative to a wall of the vessel.
