1. A fluid delivery device comprising:
- a body;
at least one cannula adapted to extend into subcutaneous tissue;
a septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture;
the septum member comprising at least one of;
a member having a puncturable section, a puncturable sidewall section, and an internal space that is in fluid communication with the cannula;
a cap-shaped member comprising an internal space that is in fluid communication with the cannula;
a cap-shaped member defining an internal space that can receive therein a tip portion of a needle when injected from plural different directions;
a member having at least two non-parallel walls that can each be punctured by a needle and defining an internal space that can receive therein a tip portion of a needle when injected from plural different directions; and
a member having a generally planar wall and a generally cylindrical wall which can each be punctured by a needle and defining an internal space that can receive therein a tip portion of a needle when injected from plural different directions; and
another internal space that is each of;
different from the internal space of the septum member;
arranged between an upper end of the cannula and the internal space of the septum member; and
in fluid communication with the internal space of the septum member.

Abstract
Fluid delivery device includes a body, a cannula adapted to extend into subcutaneous tissue, and a septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture. The septum member is at least one of; a cap-shaped member, a member having at least two non-parallel walls that can each be punctured by a needle, and a member having a generally planar wall and a generally cylindrical wall which can each be punctured by a needle.

22. A fluid delivery device comprising:
-
a body; at least one cannula adapted to extend into subcutaneous tissue; an insertion mechanism adapted to be gripped by a user and adapted to facilitate insertion of the cannula into the subcutaneous tissue; a septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture; the septum member comprising at least one of; a one-piece member having a puncturable wall, a puncturable sidewall, and an internal space that is in fluid communication with the cannula; a cap-shaped member defining an internal space that is in fluid communication with the cannula; a member having at least two non-parallel walls that can each be punctured by a needle and defining an internal space that is in fluid communication with the cannula; and a member having a generally planar wall and a generally cylindrical wall which can each be punctured by a needle, and defining an internal space that is in fluid communication with the cannula; and another internal space that is each of; different from the internal space of the septum member; arranged between an upper end of the cannula and the internal space of the septum member; and in fluid communication with the internal space of the septum member.

23. A fluid delivery device comprising:
-
a body; at least one cannula adapted to extend into subcutaneous tissue; an insertion mechanism adapted to be gripped by a user and comprising a needle portion adapted to facilitate insertion of the cannula into the subcutaneous tissue; a one-piece septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture; the septum member comprising at least one of; a member having a puncturable main wall, a puncturable sidewall, and an internal space that is in fluid communication with the cannula; a cap-shaped member comprising a main puncturable and resealable section, a side puncturable and resealable section, and an internal needle receiving space; a member having at least two non-parallel walls that can each be punctured by a needle and an internal needle receiving space; and a member having a generally planar wall, a generally cylindrical wall which can each be punctured by a needle, and an internal needle receiving space; and another internal space that is each of; different from the internal space of the septum member; arranged between an upper end of the cannula and the internal space of the septum member; and in fluid communication with the internal space of the septum member.

26. A fluid delivery device comprising:
-
a body; at least one cannula adapted to extend into subcutaneous tissue; the at least one cannula being movable relative to the body from an initial retracted position to a puncturing position; a cap-shaped septum member adapted to allow a needle to puncture the septum member from at least two different directions and to reseal each puncture once the needle is withdrawn from each puncture, and said at least one cannula having an upper end spaced from an inner surface of an upper end of the septum member when in the puncturing position, wherein the upper end of the septum member is arranged over the upper end of the cannula after the cannula is moved to the puncturing position. - View Dependent Claims (27, 28, 29, 30, 31, 32)

33. A fluid delivery device comprising:
-
a body; at least one cannula adapted to extend into subcutaneous tissue; the at least one cannula being movable relative to the body from an initial retracted position to a puncturing position; a septum member adapted to allow a needle to puncture the septum member from at least two different directions and to reseal each puncture once the needle is withdrawn from each puncture; said at least one cannula being at least one of; movable relative to the septum when the septum is coupled to the body; and movable away from the septum when moved from the initial retracted position to the puncturing position; and a support member comprising; a first opening allowing insertion of a needle along a direction parallel to an axis of the cannula and configured to allow puncturing of the septum; and at least one second opening allowing insertion of a needle along a different direction that is not arranged parallel to an axis of the cannula and configured to allow puncturing of the septum, wherein, in the retracted position, an upper end of the cannula is arranged between an upper end of the septum member and a skin attaching surface of the body.
