Vascular access port systems and methods
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.
1. A system from which one or more of a first vascular access port and a second vascular access port can be selected by a customer, the system comprising:
the first vascular access port, which is configured to be implanted subcutaneously within a patient and comprises:
a base configured to be attached to a vessel that is at a first depth within a patient;
a body comprising a palpation projection that extends away from the base, the base and the palpation projection defining a first maximum height; and
a guidance passageway that extends through the body and the base and comprises a funnel region that comprises an entry mouth of which at least a portion is spaced from the base, wherein the guidance passageway decreases in size from the entry mouth toward the base,
wherein the guidance passageway defines an opening in a bottom surface of the base and wherein the palpation projection is disposed over the opening; and
the second vascular access port, which is configured to be implanted subcutaneously within a patient and comprises:
a base configured to be attached to a vessel that is at a second depth within a patient that is greater than the first depth;
a body comprising a palpation projection that extends away from the base, the base and the palpation projection defining a second maximum height that is greater than the first maximum height; and
a guidance passageway that extends through the body and the base and comprises a funnel region that comprises an entry mouth of which at least a portion is spaced from the base, wherein the guidance passageway decreases in size from the entry mouth toward the base,
wherein the guidance passageway defines an opening in a bottom surface of the base and wherein the palpation projection is disposed over the opening.
2. The system of claim 1 , wherein the first and second vascular access ports are configured to be implanted such that the palpation projection is from about 3 mm to about 6 mm beneath a skin surface.
3. The system of claim 1 , wherein the palpation projections are configured to be palpated by a finger of a practitioner, wherein location and orientation of the first and second vascular access ports is defined.
4. The system of claim 1 , wherein the first maximum height and the second maximum height ranges from about 2 mm to about 15 mm.
5. The system of claim 1 , wherein the first and second vascular access ports are oriented in the same direction, wherein the entry mouths are distally directed following subcutaneous implantation of the first and second vascular access ports.
6. The system of claim 1 , wherein the first and second vascular access ports are oriented in opposing directions following subcutaneous implantation of the first and second vascular access ports.
