Abstract

A configurable implantable access port is provided having as individual interchangeable components a chamber body defining a fluid chamber, a body component, and a septum. The individual components may be assembled by mechanical feature, adhesive, or welding to provide a complete access port. Preferably at least the body component is provided having more than one size or geometric configuration. The access port may be tailored before implantation to a specific application by combining the chamber body and septum with a body component suitable to the specific application.

Claims

1. An implantable access port assembly comprising:

a chamber body including a base, an upstanding wall extending from said base defining a fluid chamber, and an exit port in said chamber body in fluid communication with said fluid chamber;

an interchangeable body component comprising an opening configured to receive said chamber body therein; and

a septum disposed configured to define a top of said fluid chamber;

where is said chamber body and said septum are adapted to mate with a plurality of said body components.

2. An implantable access port according to claim 1 further comprising an annular cap ring securable to said body component and sized to at least partially cover a marginal edge of said septum.

3. An implantable access port according to claim 1 wherein said body component is a suture ring having at least one suture aperture extending therethrough.

4. An implantable access port according to claim 3 further comprising a suture plug including at least one plug member configured to be received in said at least one suture aperture.

5. An implantable access port according to claim 1 wherein said chamber body comprises a biocompatible metal.

6. An implantable access port according to claim 1, wherein said chamber body comprises a biocompatible plastic.

7. An implantable access port according to claim 6, said chamber body further comprising a metallic insert member covering at least a portion of a bottom of said fluid chamber.

8. An implantable access port according to claim 1 wherein said body component comprises a molded plastic component.

9. An implantable access port kit comprising, as individual components:

a chamber body including a wall defining an open ended fluid chamber;

an interchangeable body component including a recess configured to receive said chamber body;

a septum sized to close said open ended fluid chamber defined by said chamber body, wherein said chamber body and said septum are adapted to mate with a plurality of said interchangeable body components.

10. An implantable access port kit according to claim 9 comprising a plurality of interchangeable body components, said plurality of interchangeable body components having different geometries, whereby mating said chamber body and said septum with different body components yields an access port having a different geometry.

11. An implantable access port kit according to claim 9 comprising a plurality of interchangeable body components, said plurality of interchangeable body components having different sizes, whereby mating said chamber body and said septum with different body components yields an access port having a different size.

12. An implantable access port kit according to claim 9, wherein said interchangeable body component has a generally circular profile and tapers from a relatively thick portion adjacent to said recess to a relatively thin marginal edge.

13. An implantable access port kit according to claim 9, wherein said interchangeable body component has a generally oval profile and tapers from a relatively thick region adjacent said recess to a relatively thin marginal edge.

14. An implantable access port kit according to claim 13, wherein said relatively thick region is eccentrically located in said interchangeable body component.

15. An implantable access port kit comprising, as individual components:

a chamber body including a wall defining an open ended fluid chamber;

an interchangeable suture ring including a recess configured to receive said chamber body and at least one suture aperture extending through said suture ring;

a septum sized to close said open ended fluid chamber defined by said chamber body, wherein said chamber body and said septum are adapted to mate with a plurality of said interchangeable suture rings.

16. An implantable access port kit according to claim 15 comprising a plurality of interchangeable suture rings, said plurality of interchangeable suture rings having different geometries, whereby mating said chamber body and said septum with different suture rings yield an access port having a different geometry.

17. An implantable access port kit according to claim 15 comprising a plurality of interchangeable suture rings, said plurality of interchangeable suture rings having different sizes, whereby mating said chamber body and said septum with different suture rings yield an access port having a different size.

18. An implantable access port kit according to claim 15, wherein said interchangeable body component has a generally circular profile and tapers from a relatively thick portion adjacent to said recess to a relatively thin marginal edge.

19. An implantable access port kit according to claim 15, wherein said interchangeable body component has a generally oval profile and tapers from a relatively thick region adjacent said recess to a relatively thin marginal edge.

20. An implantable access port kit according to claim 19, wherein said relatively thick region is eccentrically located in said interchangeable body component.
