Abstract:
1. A vascular access port comprising: a base that extends between a front end and a back end in a longitudinal direction and that comprises an opening; a guidance passageway that extends from an entry mouth at a proximal end thereof to the opening of the base, wherein the guidance passageway comprises a funnel region that decreases in size in a distal direction, wherein the entry mouth is open to permit one or more needles to be inserted individually through the guidance passageway and is configured to be positioned beneath a surface of the skin of a patient when the vascular access port has been implanted in the patient, 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; and an ingrowth-inducing covering on the base that is configured to promote attachment of the vascular access port to the vessel so as to maintain the opening of the port at a fixed position relative to a wall of the vessel, wherein at least a portion of the ingrowth-inducing covering is forward of the opening of the base and is rearward of the front end of the base, and wherein the guidance passageway is configured to direct the one or more needles that are inserted individually through the guidance passageway to an insertion site of the vessel that is rearward of the front end of the base when the vascular access port is attached to the vessel.
