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.

Claims

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; 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.

2. The insertion system of claim 1, 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 laterally relative to the housing.

3. The insertion system of claim 1, the compliant material for allowing pivotal movement of the piercing member relative to the housing in a case where the piercing member is in the membrane and moved laterally relative to the housing.

4. The insertion system of claim 1, the compliant material adapted to provide a seal between the piercing member and the compliant material to substantially prevent fluidic media from flowing between the compliant material and the piercing member.

5. The insertion system of claim 1, the insertion system further comprising a seal member arranged between the compliant material and the piercing member for substantially preventing fluidic media from flowing between the compliant material and the piercing member.

6. The insertion system of claim 1, the compliant material adapted to adhere to the piercing member.

7. 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.

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

13. 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.

14. The insertion system of claim 1, the housing having a chamber for containing the compliant material, at least a portion of the needle extending through the chamber of the housing.

15. The insertion system of claim 1, the insertion system further comprising:

a retaining member for retaining the compliant material within the housing.

16. The insertion system of claim 15, wherein the retaining member comprises at least one of a cap, glue joint, and a septum.

17. 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.

18. 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.

19. The insertion system of claim 18, the piercing member having a hollow interior for conveying fluidic media.

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

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

23. 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.

24. 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.

25. The insertion system of claim 1, the first opening is associated with the piercing end of the piercing member.

8. An insertion system comprising:

a housing;

a piercing member arranged at least partially within the housing, the piercing member for piercing a membrane; 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;

the piercing member having a first opening and a second opening, one of the first opening and the second opening for receiving fluidic media into a hollow interior of the piercing member, the other of the one of the first opening and the second opening for allowing the fluidic media to exit the hollow interior of the needle;

wherein the compliant material is arranged at least partially in between the first opening and the second opening.

9. The insertion system of claim 8, wherein the compliant material is arranged completely between the first opening and the second opening.

26. The insertion system of claim 8, the piercing member having a piercing end located outside of the housing.

10. An insertion system comprising:

a housing;

a piercing member arranged at least partially within the housing, the piercing member for piercing a membrane; 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;

the piercing member having a first opening and a second opening, one of the first opening and the second opening for receiving fluidic media into a hollow interior of the piercing member, the other of the one of the first opening and the second opening for allowing the fluidic media to exit the hollow interior of the needle;

the compliant material having a body for supporting the piercing member;

the body having a recess in fluid flow communication with one of the first opening and the second opening.

11. The insertion system of claim 10, the recess defined by a surface sloped to correspond generally to an angle of articulation of the piercing member relative to the housing.

27. The insertion system of claim 10, the piercing member having a piercing end located outside of the housing.

20. A method of making an insertion system, the method comprising:

providing a housing;

arranging a piercing member at least partially within the housing, the piercing member having a piercing end located outside of the housing for piercing a membrane; and

arranging a compliant material 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.
