1. A therapeutic fluid delivery system comprising:
- a first reservoir configured to house a first therapeutic fluid;
a second reservoir configured to house a second therapeutic fluid;
an inlet port configured to receive a first fluid delivery needle having a first diameter and a second fluid delivery needle having a second diameter less than the first diameter, wherein the inlet port comprises a first septum and a second septum, andwherein the inlet port is configured for fluid communication between the first fluid delivery needle and the first reservoir when the first fluid delivery needle penetrates the first septum but not the second septum, and the inlet port is further configured for fluid communication between the second fluid delivery needle and the second reservoir when the second fluid delivery needle penetrates both the first septum and the second septum; and
wherein the inlet port exhibits a reduced cross-sectional area between the first septum and the second septum such that the second needle exhibiting the second diameter less than the first diameter can access both the first septum and the second septum, while the first needle exhibiting the first diameter can access the first septum but not the second septum.

36. A method comprising:
-
inserting a first fluid delivery needle having a first diameter into an inlet port of a fluid delivery device to a first depth sufficient to penetrate a first septum of the inlet port but not a second septum of the inlet port to selectively access a first reservoir; inserting a second fluid delivery needle having a second diameter less than the second diameter into the inlet port of the fluid delivery device to a second depth greater than the first depth to penetrate both the first septum and the second septum to selectively access a second reservoir different from the first reservoir; delivering fluid from the first fluid delivery needle to the first reservoir when the first fluid delivery needle penetrates the first septum but not the second septum; and delivering fluid from the second fluid delivery needle to the second reservoir when the second fluid delivery needle penetrates both the first septum and the second septum; wherein the inlet port exhibits a reduced cross-sectional area between the first septum and the second septum such that the second needle exhibiting the second diameter less than the first diameter can access both the first septum and the second septum, while the first needle exhibiting the first diameter can access the first septum but not the second septum. - View Dependent Claims (37)

38. A fluid delivery system comprising:
-
first means for housing a first therapeutic fluid; second means for housing a second therapeutic fluid; means for receiving a first fluid delivery needle having a first diameter and a second fluid delivery needle having a second diameter less than the first diameter, wherein the means for receiving the first fluid delivery needle and the second fluid delivery needle comprises a first septum and a second septum, and wherein the first means for housing the first therapeutic fluid is in fluid communication with the first fluid delivery needle when the first fluid delivery needle penetrates the first septum but not the second septum, and wherein the second means for housing the second therapeutic fluid is in fluid communication with the second fluid delivery needle when the second fluid delivery needle penetrates both the first septum and the second septum; and wherein the means for receiving the first fluid delivery needle and the second delivery needle exhibits a reduced cross-sectional area between the first means for housing the first therapeutic fluid and the second means for housing the second therapeutic fluid such that the second needle exhibiting the second diameter less than the first diameter can access both the first means for housing the first therapeutic fluid and the second means for housing the second therapeutic fluid, while the first needle exhibiting the first diameter can access the first means for housing the first therapeutic fluid but not the second means for housing the second therapeutic fluid. - View Dependent Claims (39)
