Abstract
In certain systems disclosed herein, one or more of a first vascular access port and a second vascular access port can be selected by a customer. Each of the first and second vascular access ports can be implanted subcutaneously within a patient, and each can include a base configured to be attached to a vessel, a body that extends away from the base, and a guidance passageway that extends through the body and the base and includes a funnel region. A maximum height defined by the base and body of the second vascular access port can be greater than a maximum height defined by the base and body of the first vascular access port.
Claims11
A vascular access port comprising:
- a base having an opening, a top surface, and a bottom surface, the base extending between a front end and a back end in a longitudinal direction;
- a guidance passageway that extends from an entry mouth at a proximal end thereof to the opening of the base, the guidance passageway including a funnel region that decreases in size in a distal direction;
- a palpation projection extending along at least a portion of the entry mouth of the funnel region;
- and
- a supplemental palpation projection positioned in a transverse direction at a forward end of the vascular access port and spaced from the funnel region by a recess,
- wherein a central axis extending through the guidance passageway defines an acute angle relative to a longitudinal length of the base, and the entry mouth is open to permit one or more needles to be inserted 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.
