Abstract

In one aspect, a drug delivery device is provided herein including: a monolithic body having a plurality of fluid ducts and at least one outlet duct formed therein; a plurality of drug cartridges attached to the body, the drug cartridges each including a reservoir for accommodating at least one drug wherein, the plurality of fluid ducts is arranged to convey the drugs from the drug cartridges to the at least one outlet duct; and, a needle support spaced from the body, the needle support including a needle configured for insertion into a patient for drug delivery, the needle support including adhesive for releasable securement to a patient, wherein, the needle support is connected to the body by a flexible tether through which passes at least one fluid passageway formed to convey drug from the at least one outlet duct to the needle.

First claim

1 .- 22 . (canceled)

23 . A drug delivery device comprising:
a body having a plurality of fluid ducts and at least one outlet duct formed therein; and, a plurality of drug cartridges attached to the body, the drug cartridges each including a reservoir for accommodating at least one drug, wherein, a first of the drug cartridges includes a fluid outlet, wherein, a first of the fluid ducts, is aligned to extend from the fluid outlet, wherein, an adjustable seal, formed by a sealing sheet joined to a sealing surface, selectively seals the fluid outlet, the seal being adjustable from a first state, where the fluid outlet is sealed, to a second state, where the fluid outlet is not sealed, wherein the sealing sheet is secured to a shiftable sealing element, and,
wherein displacement of the shiftable sealing element causes delamination of the sealing sheet from the sealing surface results in adjustment of the seal from the first state to the second state.

24 .- 77 . (canceled)

78 . The drug delivery device of claim 23 , wherein the shiftable sealing element includes multiple open passageways which come into alignment with the fluid outlet with the seal being in the second state.

79 . The drug delivery device of claim 78 , wherein the open passageways are provided at multiple radial locations about the shiftable sealing element.

80 . The drug delivery device of claim 23 , wherein the shiftable sealing element is displaced in response to pressure being applied thereto.

81 . The drug delivery device of claim 23 , wherein the shiftable sealing element is initially seated in a well, the sealing surface being located about the well.

82 . The drug delivery device of claim 81 , wherein the shiftable sealing element is displaced to protrude from the well in causing the sealing sheet to delaminate from the sealing surface.

83 . The drug delivery device of claim 81 , wherein the fluid outlet includes a divergent portion leading into the well and a convergent portion leading out of the well.

84 . The drug delivery device of claim 23 , wherein the sealing sheet is a thermoformable film.
