IMPLANTABLE ACCESS PORT
First Claim
1. An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient'"'"'s body, said access port comprising:
- a base;
a means for increasing the purging performance of the port, comprising;
a bowl-shaped reservoir defined within the base by a smooth surfaced wall, wherein the reservoir has a top edge, a bottom portion and a side portion that extends between the bottom portion and the top edge;
a reservoir outlet defined on the side portion of the reservoir; and
an outlet passageway in communication with the reservoir outlet, wherein the reservoir outlet and the outlet passageway are positioned in a plane that overlies and is spaced from a center of the bottom portion of the reservoir and the top edge of the reservoir; and
a septum secured to the base and enclosing the reservoir within the base.

Abstract
An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient'"'"'s body is disclosed. The access port includes a base, a bowl-shaped reservoir defined within the base by a smooth surfaced wall, and a septum secured to the base and enclosing the reservoir within the base. The access port also has an outlet passageway defined within the base and extending in communication with a reservoir outlet defined within the reservoir and an external opening defined in the exterior of the base.

27. An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient'"'"'s body, said access port comprising:
-
a housing comprising a base having a shoulder surface; a retainer ring configured for connecting to an exterior portion of the base, wherein the retainer ring defines an access aperture circumferentially surrounded by a lip portion, wherein, when the retainer ring is connected to the base, the upper shoulder surface of the base and the lip portion of the retainer ring define a circumferentially extending slot having a height dimension; and a means for increasing the purging performance of the access port, comprising; a bowl-shaped reservoir defined within the base by a smooth surfaced wall, wherein the reservoir has a top edge, a bottom portion and a side portion that extends between the bottom portion and the top edge, wherein the top edge of the reservoir adjoins the shoulder surface of the base; a reservoir outlet defined on the side portion of the reservoir; and an outlet passageway in communication with the reservoir outlet, wherein the reservoir outlet and the outlet passageway are positioned in a plane that overlies and is spaced from a center of the bottom portion of the reservoir and the top edge of the reservoir; and a septum having an edge portion, wherein the septum is substantially planar and has a substantially uniform height, and wherein the edge portion of the septum is configured to be received therein the formed circumferentially extending slot such that the edge portion of the septum is compressively seated therebetween the base and the retainer ring and seals the access aperture of the retainer ring. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. A method of identifying a subcutaneously implanted access port, comprising:
-
a) providing a subcutaneously implanted access port comprising; a base; a means for increasing the purging performance of the port, comprising; a bowl-shaped reservoir defined within the base by a smooth surfaced wall, wherein the reservoir has a top edge, a bottom portion and a side portion that extends between the bottom portion and the top edge; a reservoir outlet defined on the side portion of the reservoir; and an outlet passageway in communication with the reservoir outlet, wherein the reservoir outlet and the outlet passageway are positioned in a plane that overlies and is spaced from a center of the bottom portion of the reservoir and the top edge of the reservoir; and a septum secured to the base and enclosing the reservoir within the base; and b) perceiving at least one feature of the subcutaneously implanted access port; and c) identifying the subcutaneously implanted access port in response to perceiving the at least one feature. - View Dependent Claims (46, 47, 48)
