Abstract

A piercing member for piercing a membrane may be arranged within a housing and supported by a compliant that may be for allowing articulation of the piercing member relative to the housing in a case where the piercing member is in the membrane and moved relative to the housing.

First claim

What is claimed is:

1. An insertion system, the insertion system comprising:
a housing;
a piercing member arranged partially within the housing, the piercing member having a piercing end located outside of the housing for piercing a membrane, the piercing member having a hollow interior for conveying fluidic media; and
a compliant material arranged within the housing to support the piercing member and attach the piercing member to the housing, the compliant material for allowing articulation of the piercing member relative to the housing in a case where the piercing member is in the membrane and moved relative to the housing;
wherein the piercing member extends through the compliant material and has a first end located on an opposite side of the compliant material with respect to the piercing end of the piercing member.

2. The insertion system of claim 1 , the compliant material provides a fluid seal between the piercing member and the compliant material and between the housing and the compliant material, to substantially prevent fluidic media from flowing between the compliant material and the piercing member, and between the compliant material and the housing.

3. The insertion system of claim 1 , the compliant material forms a fluid seal with the housing and with the piercing member.

4. The insertion system of claim 1 , the compliant material arranged to support the piercing member such that the piercing member does not contact the housing.

5. The insertion system of claim 1 , wherein the piercing member comprises a needle.

6. The insertion system of claim 1 , the housing having a fluid channel for alignment with a reservoir, the fluid channel in fluid communication with a hollow interior of the piercing member.

7. The insertion system of claim 1 , the housing having a chamber for for receiving fluidic media, the chamber located on one side of the compliant material; and the compliant material having a surface defining an inner wall of the chamber for contacting fluidic media received within the chamber.

8. The insertion system of claim 1 , the insertion system further comprising:
a retaining member for retaining the compliant material within the housing.

9. The insertion system of claim 8 , wherein the retaining member comprises at least one of a cap, glue joint, and a septum.

10. The insertion system of claim 1 , wherein the housing is made of the compliant material to allow articulation of the piercing member relative to the housing in a case where the piercing member is moved relative to the housing.

11. The insertion system of claim 1 , wherein the membrane comprises skin of a patient, the compliant material for allowing articulation of the piercing member relative to the housing in a case where the piercing member is in the skin of the patient and moved relative to the housing.

12. The insertion system of claim 1 , wherein a fluid flow passage is provided through at least a portion of the compliant material.

13. The insertion system of claim 1 , the complaint material being adhered to the housing, to remain in a fixed position relative to the housing.

14. The insertion system of claim 1 , the piercing member having a longitudinal dimension that extends out from the housing such that a portion of the piercing member is located within the housing and another portion of the piercing member is located external to the housing.

15. The insertion system of claim 1 , the piercing member having a hollow central channel and first and second openings in communication with the central channel of the piercing member; and
the housing having an internal channel and an external opening in fluid flow communication with the internal channel, for connection with an external fluid flow path, the internal channel being in fluid flow communication with the first opening of the piercing member.

16. The insertion system of claim 1 , further comprising a needle to place the piercing member in the membrane.

17. The insertion system of claim 1 , wherein the piercing member and the complaint material is in the housing as the fluidic media passes through the hollow interior of the piercing member.

18. The insertion system of claim 1 , wherein:
the piercing member has a longitudinal dimension extending along a length dimension of the housing, at an angle of orientation relative to the length dimension of the housing; and
the compliant material allows articulation of the piercing member in a direction that changes the angle of orientation of the longitudinal dimension of the piercing member relative to the length dimension of the housing.

19. The insertion system of claim 18 , wherein the compliant material allows articulation of the piercing member by an amount that changes the angle of orientation of the longitudinal dimension of the piercing member relative to the length dimension of the housing by up to 30 degrees.

20. The insertion system of claim 1 , wherein:
the piercing member has a longitudinal dimension extending along a length dimension of the housing; and
the compliant material allows articulation of the piercing member in a direction lateral to the length dimension of the housing.

21. The insertion system of claim 1 , wherein the housing has a chamber for receiving a fluidic media, the compliant material has a surface defining an inner wall of the chamber, the inner wall arranged for contacting fluidic media received in the chamber.

22. The insertion system of claim 21 , wherein the surface of the compliant material that defines the inner wall of the chamber has a recess arranged for contacting fluidic media received in the chamber, and wherein the first end of the piercing member extends into the recess.

23. An insertion system comprising:
a housing;
a piercing member arranged at least partially within the housing, the piercing member having a piercing end located outside of the housing for piercing a membrane, the piercing member having a first end opposite the piercing end; and
a compliant material arranged within the housing to support the piercing member, the compliant material for allowing articulation of the piercing member relative to the housing in a case where the piercing member is in the membrane and moved relative to the housing;
wherein piercing member extends through the compliant material
wherein the housing includes a chamber for receiving fluidic media, the chamber located on one side of the compliant material; and
wherein the first end of the piercing member is located in the chamber and outside of the compliant material, the first end has an opening to the hollow interior of the piercing member, and the opening remains outside of the compliant material and in fluid flow communication with the chamber.

24. The insertion system of claim 23 , wherein the compliant material forms at least one inner wall of the chamber for contacting fluidic media received in the chamber.

25. The insertion system of claim 23 , wherein the compliant material has a surface defining an inner wall of the chamber, the surface having a recess for contacting fluidic media received in the chamber, the first end of the piercing member extending in the recess.

26. The insertion system of claim 23 , the compliant material forms a fluid seal with the housing and with the piercing member.

27. An insertion system comprising:
a housing;
a piercing member arranged at least partially withi
