10/715,985, filed Nov. 18, 2003 which is incorporated in its entirety by
1.  An infusion set comprising: a substantially round base having upper and lower sides, a base cannula extending downwardly from the lower side, a notched outer rim, and a
port extending upwardly from the upper side, the port being in fluid communication with the base cannula, and the port comprising a septum adapted to seal said port from fluid communication therethrough, the septum being substantially flush with a top
edge of the port, and the port being substantially cylindrical and the port having an outer diameter substantially closer in size to the diameter of the septum than to the diameter of the base;  an adhesive layer mounted to the lower side of the base;
an introducer cap adapted to be pressed against the upper side of the base and removably coupled to the base, the introducer cap comprising upper and lower sides, and a needle extending downwardly from the lower side, the needle being adapted to extend
through the septum on the upper side of the base and through the base cannula on the lower side of the base, whereby the attached base and introducer cap are adapted to be pressed against a patient&#39;s skin such that the introducer needle pierces the skin
and the adhesive layer on the lower side of the base contacts the skin, the introducer cap having at least one retaining member configured to couple to the notched outer rim of the base and two tabs extending upwardly from the upper side of the
introducer cap configured to decouple the at least one retaining member from the notched rim when a force is applied to at least one of the tabs;  an infusion cap comprising an upper side and a lower side, the infusion cap being adapted to be pressed
against the upper side of the base and removably attached to the base after disengagement of the introducer cap from the base, the infusion cap being adapted to rotate with respect to the base while engaged, the infusion cap comprising an infusion
cannula extending downwardly from the lower side of the infusion cap, and an elongate flexible lumen in fluid communication with the infusion cannula, the infusion cannula being adapted to extend through the septum on the upper side of the base upon
engagement of the infusion cap and the base to place the flexible lumen and the infusion cap in fluid communication with the base cannula.
2.  The infusion set of claim 1, wherein the notched outer rim is located at a radially-outermost periphery of the base.
3.  The infusion set of claim 1, wherein the at least one retaining member comprises a foot.
4.  The infusion set of claim 1, wherein the introducer cap further comprises at least a second retaining member configured to couple to the notched outer rim of the base.
5.  The infusion set of claim 4, wherein retaining members are diametrically opposed.
6.  The infusion set of claim 1, wherein the infusion cap further comprises a cylindrical wall extending downwardly from the lower side, the cylindrical wall configured to provide a substantially close fit with the port.
7.  The infusion set of claim 6, wherein the cylindrical wall extends downwardly beyond the infusion cannula.
8.  An infusion set comprising.  a base having upper and lower sides, a base cannula extending downwardly from the lower side, a rim, and a port extending upwardly from the upper side, the port being in fluid communication with the base cannula,
and the port comprising a septum adapted to inhibit fluid communication through the port, the septum being approximately flush with a top edge of the port, and the port being substantially cylindrical with an outer diameter slightly larger than the
diameter of the septum;  an introducer cap adapted to be pressed against the upper side of the base and removably connected to the base at the rim, the introducer cap comprising upper and lower sides, and a needle extending downwardly from the lower
side, the needle being adapted to extend through the septum on the upper side of the base and through the base cannula on the lower side of the base, whereby the base and introducer cap when connected are adapted to be pressed against a patient&#39;s skin
such that the introducer needle pierces the skin;  an infusion cap comprising an upper side and a lower side, the infusion cap being adapted to be pressed against the upper side of the base and removably connected to the base at the rim, the infusion cap
being adapted to rotate with respect to the base while connected to the base, the infusion cap comprising an infusion cannula extending downwardly from the lower side of the infusion cap, and the infusion cannula being adapted to extend through the
septum on the upper side of the base upon engagement of the infusion cap and the base.
9.  The infusion set of claim 8, wherein the base is substantially circular.
10.  The infusion set of claim 8, wherein the rim comprises a notch.
11.  The infusion set of claim 8, further comprising an adhesive layer mounted to the lower side of the base.
12.  The infusion set of claim 8, wherein the introducer cap further comprises at least one retaining member configured to couple to the rim of the base.
13.  The infusion set of claim 12, wherein the introducer cap further comprises two tabs extending upwardly from the upper side of the introducer cap configured to decouple the at least one retaining member from the rim when a force is applied
to at least one of the tabs.
14.  The infusion set of claim 8, wherein the infusion cap further comprises an elongate flexible lumen in fluid communication with the infusion cannula.
15.  The infusion set of claim 8, wherein the rim is located at a radially-outermost periphery of the base.
16.  The infusion set of claim 12, wherein the at least one retaining member comprises a foot.
17.  The infusion set of claim 12, wherein the introducer cap further comprises at least a second retaining member configured to couple to the rim of the base.
18.  The infusion set of claim 17, wherein retaining members are diametrically opposed.
19.  The infusion set of claim 8, wherein the infusion cap further comprises a cylindrical wall extending downwardly from the lower side, the cylindrical wall configured to provide a substantially close fit with the port.
20.  The infusion set of claim 19, wherein the cylindrical wall extends downwardly beyond the infusion cannula.  Description
the skilled artisan.  According to one embodiment, the needle-receiving section 22 extends partially into the c avity 84 of the port-engaging portion 74 to provide additional length along which the needle 66 will be supported.  The supported length of
the needle (i.e. the length of the needle held within the needle-holding lumen 22) can vary as needed for needles of various lengths.  For example, in the case of a needle with an overall length of about 1&#39;&#39;, a needle-receiving section preferably has a
In the illustrated embodiment, the introducer cap 64 is generally circular as viewed from above (see FIG. 2).  As shown in FIG. 2, a pair of release grips 100 are provided on opposite sides of the circular cap 64 in the area of the barbed feet 94
soften the material of the wall.  Once the port wall 136 material has been softened, it can be deformed radially inward slightly so as to trap the septum 130 in the cavity 132 of the port 62.  The heat staking procedure can be performed uniformly around
the circumference of the port, or at intervals around the wall 136.  The skilled artisan will recognize that alternative methods can also be used for securing the septum within the cavity 132, such as bonding, welding, etc as described above.

diameter of the port-engaging portion 74 is about 0.025&#39;&#39; to about 0.1&#39;&#39; larger than the port 62 of the base member 60.  Depending upon the desired application, in alternative embodiments, the inner diameter may be outside of this range.
Similarly to the introducer cap 64, the infusion cap 54 also preferably comprises release grips 100 which can be compressed to release the cap from engagement with the base member 60.  In the embodiment illustrated in FIG. 10, the release grips
member.  In still further embodiments, the barbed feet 94 may be omitted, as discussed above, or replaced with a suitable alternative structure, thereby allowing a user to merely pull outward on the introducer cap 64 to remove the needle 66.
