Abstract

An implantable access port for use in transferring fluid transdermally between an external fluid storage or dispensing device and a site within a patient is disclosed. The access port includes a body, at least two reservoirs defined within the access port body, and at least one septum secured to the body and enclosing the reservoirs within the body. The access port also includes reservoir outlets defined within the reservoirs. The access port also has body conduits defined within the body and in fluid communication with the reservoir outlets and external openings defined in the exterior of the body. An implantable access port and system for use in apheresis is also provided that includes an implantable access port, at least one needle, and a catheter that is fluidly connected to the access port.

First claim

What is claimed is:

1. An implantable vascular access port comprising:
a first reservoir having a first opening extending to a top surface of the port, the first opening fluidly sealed by a first septum, and a first outlet in fluid communication with the first reservoir; and
a second reservoir having a second opening extending to the top surface of the port, the second opening fluidly sealed by a second septum, and a second outlet in fluid communication with the second reservoir;
wherein the first and second reservoir are separated by and adjacent to a common wall, the common wall having a first end portion, a second end portion, and an intermediate portion between the first and second end portions,
wherein each of the first and second reservoirs include a curved side surface,
wherein the first and second end portions of the common wall intersect the curved side surfaces of the first and second reservoirs to form rounded corners,
wherein the first outlet is defined proximate the rounded corner of the first reservoir,
wherein the second outlet is defined proximate the rounded corner of the second reservoir,
wherein the first and second opening comprise edges of the common wall at a top surface of the port, the edges at the intermediate portion being substantially parallel to a common linear axis, and
wherein the first and second septums are disposed on opposite sides of the common linear axis; and
an access port retainer comprising a first retainer opening and a second retainer opening, the first retainer opening and the second retainer opening having an opposing D-shaped configuration, the first retainer opening and second retainer opening being separated by a dividing member that is aligned with the reservoir common wall, tire first retainer opening overlaying the second reservoir; and
a substantially circular footprint.

2. The implantable vascular access port of claim 1 further comprising the first and second reservoir having opposing D-shaped configuration.

3. The impassable vascular access port of claim 1 further comprising: the first and second septum having an opposing D-shaped configuration.

4. The implantable vascular access port of claim 3 , further comprising: the first septum and the second septum being needle penetrable and aligned between the first reservoir and second reservoir and the first retainer opening and second retainer opening.

5. The implantable vascular access port of claim 3 , further comprising: the septum having a lower shoulder surface extending about and between the first septum and second septum and aligned with the retainer dividing member and reservoir common wall.

6. The implantable vascular access port of claim 1 , wherein the top surface of the port has a substantially circular profile.

7. An implantable vascular access port, comprising:
a first reservoir having a first opening extending to a top surface of the port, the first opening fluidly sealed by a first septum, and a first outlet in fluid communication with the first reservoir; and
a second reservoir having a second opening extending to the top surface of the port, the second opening fluidly sealed by a second septum, and a second outlet in fluid communication with the second reservoir;
wherein the first and second reservoir are separated by and adjacent to a common wall, and
wherein the first and second septums have an opposing D-shaped configuration; and
an access port retainer comprising a first retainer opening and a second retainer opening, the first retainer opening and the second retainer opening having an opposing D-shaped configuration, the first retainer opening and second retainer opening being separated by a dividing, member that is aligned with the reservoir common wall, the first retainer opening substantially overlaying the first, reservoir and the second retainer opening substantially overlaying the second reservoir; and
a substantially circular footprint.

8. The implantable vascular access port of claim 7 further comprising: the first and second reservoir having an opposing D-shaped configuration.

9. The implantable vascular access port of claim 7 , herein the top surface of port substantially circular profile.
