Abstract

A tissue penetrating system has a housing member. A plurality of penetrating members are positioned in the housing member. A tissue stabilizing member is coupled to the housing. A penetrating member sensor is coupled to the plurality of penetrating members. The penetrating member sensor is configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.

Claims

1. A medicament delivery system, comprising:

a housing member;

one or more penetrating members positioned in the cartridge;

a controllable driver configured to be coupled to the one or more penetrating members;

a processor configured to be coupled to each of a penetrating member and the controllable driver, the processor customizing a user profile in response to user input information, the processor providing for localization of an injection of a medicament;

a database that stores information for each user profile.

2. The system of claim 1, further comprising:

a cartridge positionable in the housing member.

3. The system of claim 1, wherein the user profile is used to determine at least one of an amount of medicament delivered, when a medicament is delivered, and a phase of penetrating member movement for medicament deliver.

9. The system of claim 1, further comprising:

a medicament container.

10. The system of claim 1, wherein the medicament container is a collapsible canister configured to be coupled to a penetrating member and actuatable by the controllable driver.

11. The system of claim 10, wherein the medicament injection module houses the medicament to be injected.

12. The system of claim 1, further comprising:

a plurality of medicament injection modules.

13. The system of claim 12, wherein the plurality of medicament injection modules are positioned in a cartridge.

14. The system of claim 12, wherein the plurality of medicament injection modules provide a series of metered doses.

15. The system of claim 14, wherein the metered doses provide for a long-term medication need.

16. The system of claim 13, wherein the medicament injection modules and the one or more penetrating members are housed in a cartridge.

17. The system of claim 16, wherein the cartridge is disposable.

18. The system of claim 1, wherein the controllable driver and processor provide for an ability to precisely determine a position or penetration depth of the one or more penetrating members.

19. The system of claim 1, wherein penetrating member is a hypodermic needle.

20. The system of claim 1, wherein each of a one or more penetrating member is coupled to a coupler.

21. The system of claim 3, wherein the processor and controllable driver provide for medicament delivery at a point of maximum penetration of the one or more penetrating members.

22. The system of claim 3, wherein the processor and controllable driver provide for medicament delivery during a retraction of the one or more penetrating members.

23. The system of claim 3, wherein the processor and controllable driver provide for medicament delivery during insertion of the one or more penetrating members.

24. The system of claim 1, wherein the processor and controllable driver provide for The hollow hypodermic needle is fitted with the collapsible canister containing a drug or other agent to be dispensed. The walls of this collapsible canister can be made of a soft resilient material such as plastic, rubber, or any other suitable material.

25. The system of claim 9, wherein a plate is disposed at a distal end of the medicament container.

26. The system of claim 25, wherein the plate is sealed and secured to a shaft of the one or more penetrating members to prevent leakage of the medicament from the medicament container.
