1. A vascular access port comprising:
- a bottom surface configured to face a vessel when the vascular access port is coupled to the vessel, wherein the bottom surface includes an opening therein;
a body that extends away from the bottom surface, wherein the body is configured to remain beneath an outer surface of skin after the vascular access port has been implanted; and
a guidance passageway that extends through at least a portion of the body, wherein a central axis defined by the guidance passageway extends through the opening in the bottom surface such that the guidance passageway is configured to constrain one or more needles inserted individually therethrough to pass through the opening and through a specific region of a vessel when the vascular access port is coupled to the vessel, and wherein the guidance passageway is devoid of a closure apparatus.

Abstract
Ports for accessing a vessels within a patient include passageways that can guide needles or other access devices directly into the vessels. The ports can be implanted subcutaneously within a patient. Some ports may be used in the creation and use of vascular access buttonholes.

25. A vascular access port comprising:
-
a bottom surface configured to face a vessel when the vascular access port is coupled to the vessel; a body that extends away from the bottom surface, wherein the body is configured to remain beneath an outer surface of skin after the vascular access port has been implanted; a guidance passageway that extends through at least a portion of the body to an opening in the bottom surface, wherein the guidance passageway is devoid of a closure apparatus; an implantation passageway that extends through at least a portion of the body and that defines the opening in the bottom surface of the vascular access port, wherein the implantation passageway is connected to the guidance passageway; and a closure device at an upper end of the implantation passageway, wherein the closure device is configured to seal the upper end of the implantation passageway after at least a portion of a percutaneous implantation device has been removed therefrom. - View Dependent Claims (26, 27)

28. A method comprising:
-
forming an opening in a sidewall of a vessel using a percutaneous implantation device; providing a vascular access port that comprises an implantation passageway and a guidance passageway that are connected to each other, wherein at least a portion of the percutaneous implantation device extends through the implantation passageway, wherein the guidance passageway is devoid of a closure apparatus; positioning the vascular access port at the sidewall of the vessel such that an opening at a bottom end of the implantation passageway in a bottom surface of the vascular access port is in fluid communication with a lumen of the vessel via the opening in the sidewall of the vessel; removing the at least a portion of the percutaneous implantation device from the implantation passageway; sealing an upper end of the implantation passageway; and closing an implantation tract such that the vascular access port is entirely beneath a skin surface. - View Dependent Claims (29)
