Abstract: Embodiments may include a method of delivering a drug. The method may include removing or releasing a structure from a patch-pump assembly. The patch-pump assembly may include a sealed prefilled drug-reservoir, a fluid passageway, a cannula-containing assembly, and a penetrator. The method may also include penetrating the sealed prefilled drug-reservoir containing the drug to establish fluid communication between the sealed prefilled drug-reservoir and a fluid passageway by removing or releasing the structure. The method may further include flowing the drug from the prefilled drug-reservoir to the fluid passageway. In addition, the method may include flowing the drug from the fluid passageway to a cannula-containing assembly. Furthermore, the method may include delivering the drug subcutaneously to a subject using the cannula-containing assembly.

Abstract: Embodiments of the present invention provide drug-delivery devices comprising a drug reservoir chamber containing a substance to be delivered, in fluid connection with a drug administration means, and at least one displacement-generating battery cell coupled to said drug reservoir chamber by a coupling means, the at least one displacement-generating battery cell comprising an element that changes shape as a result of discharge of the battery cell so as to cause a displacement within the battery unit, the arrangement being such that the displacement derived from said battery unit is conveyed by said coupling means to cause displacement of at least a portion of a wall of said drug reservoir chamber reducing the volume of said drug reservoir chamber such that said substance is expelled from said drug reservoir chamber towards said drug administration means upon discharge, thereby being a self-powered drug delivery device.
