Abstract

An access portal is provided including a housing, a body defining a fluid reservoir, and a septum enclosing the fluid reservoir. A stem in fluid communication with the fluid reservoir extends from the fluid reservoir. The access portal also includes a reservoir insert disposed within the fluid reservoir, in which the reservoir insert decreases the fluid fill volume of the reservoir.

Claims

1. An access portal comprising:

a fluid reservoir;

a septum sealing an open region of said fluid reservoir; and

a reservoir insert disposed within said fluid reservoir, said reservoir insert comprising a plurality of protrusions coupled to one another via a webbing to form a ring member, wherein said reservoir insert generally defines a central region, said central region extending unobstructed from a base of said fluid reservoir to said septum.

2. The access portal according to claim 1, further comprising a stem in fluid communication with said fluid reservoir via an outlet passage.

3. The access portal according to claim 1, wherein said reservoir insert is rotatable within said fluid reservoir.

4. The access portal according to claim 1, further comprising a housing at least partially surrounding said fluid reservoir.

5. The access portal according to claim 4, wherein said housing defines an opening on a top surface thereof, said opening defining a curved margin shaped and sized to guide an injection device in a direction of said septum.

6. An access portal comprising:

a fluid reservoir;

a septum sealing an open region of said fluid reservoir; and

a plurality of protrusions projecting from at least one of a bottom or a sidewall of said fluid reservoir, said plurality of protrusions configured to reduce a fluid fill volume of said fluid reservoir.

7. The access portal according to claim 6, wherein said plurality of protrusions project from said bottom of said fluid reservoir.

8. The access portal according to claim 6, wherein said plurality of protrusions project from said sidewall of said fluid reservoir.

9. The access portal according to claim 6, wherein said plurality of protrusions generally define a central region, said central region extending unobstructed from said base of said fluid reservoir to said septum.

10. The access portal according to claim 6, further comprising a stem in fluid communication with said fluid reservoir via an outlet passage.

11. The access portal according to claim 6, further comprising a housing at least partially surrounding said body.

12. An access portal comprising:

a fluid reservoir;

a septum sealing an open region of said fluid reservoir;

a reservoir insert disposed within said fluid reservoir, said reservoir insert comprising a plurality of protrusions configured to reduce a fluid fill volume of said fluid reservoir;

at least one aperture configured to receive a suture and to secure said access portal to a patient tissue; and

a plug member shaped and sized to be at least partially received within said at least one aperture.

13. The access portal according to claim 12, wherein said plurality of protrusions are coupled to one another via a webbing to form a ring member.

14. The access portal according to claim 12, wherein said plurality of protrusions extend from at least one of a bottom or a sidewall of said fluid reservoir.

15. The access portal according to claim 12, wherein said reservoir insert generally defines a central region, said central region extending unobstructed from said base of said fluid reservoir to said septum.

16. The access portal according to claim 12, further comprising a stem in fluid communication with said fluid reservoir via an outlet passage.

17. The access portal according to claim 12, wherein said reservoir insert is rotatable within said fluid reservoir.

18. The access portal according to claim 12, further comprising wherein a housing defining an opening on a top surface thereof, said opening defining a margin portion shaped and sized to guide an injection device in a direction of said septum.
