TRANSDERMAL PATCH SYSTEM
First Claim
1. A system for transdermal drug delivery, comprising:
- a housing configured for placement upon a skin surface,a drug delivery mechanism within or along the housing positioned to contact the skin surface; and
a reservoir contained within or along the housing and fluidly coupled to the drug delivery mechanism, wherein the reservoir comprises an elongate microchannel extending within or along the housing.

Abstract
A transdermal patch system configured as a patch or pump assembly may be placed into contact upon a skin surface to transport drugs or agents transdermally via any number of different mechanisms such as microporous membranes, microneedles, in-dwelling catheters, etc. The assembly may enclose or accommodate a reservoir configured as an elongate microchannel to contain the drug or agent suspended in a fluid vehicle. The reservoir may also be fluidly coupled via microchannels to transport the drugs into or against an underlying skin surface as driven or urged via a pump and controlled by an electronic control circuitry which may be programmed to affect any number of treatment regimens.

30. A method of delivering one or more drugs transdermally, comprising:
-
positioning a housing upon or in proximity to a skin surface; pumping one or more drugs to a drug delivery mechanism placed onto or through a skin surface underlying the housing, and wherein the one or more drugs are contained within an elongate microchannel reservoir located within or along the housing. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

57. A system for transdermal drug delivery, comprising:
-
a housing configured for placement upon a skin surface; a drug delivery mechanism within or along the housing positioned to contact the skin surface; a reservoir contained within or along the housing and fluidly coupled to the drug delivery mechanism; and a linear actuator having a transducer vibrationally coupled to a translatable element positioned within the reservoir, wherein the translatable element is configured to translate within the reservoir in a controlled manner upon vibrational actuation of the transducer. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)
