Abstract
Devices, systems and methods directed to a drug delivery device including a soft subcutaneously insertable cannula are disclosed. Some embodiments of the cannula include an elongated soft tube having a plurality of apertures spaced around and/or along a wall of the elongated soft tube. The plurality of apertures is configured for fluid flow therethrough resulting-in/causing an increase in an absorption rate of the fluid in the body of the user. The drug delivery device can be an insulin pump.

62. A method for increasing the absorption rate of a therapeutic fluid in the body of a user/patient comprising:
-
providing a cannula for dispensing of the therapeutic fluid into a tissue of a user/patient, the cannula comprising; a soft tube having a plurality of apertures, the plurality of apertures being configured for delivering the fluid to the tissue; a connector provided on a proximal end of the soft tube for establishing fluid communication between a fluid delivery device and the cannula; inserting the cannula into a tissue of the user/patient via a rigid penetrating member having a sharp tip; and dispensing the therapeutic fluid through the cannula, wherein the therapeutic fluid flows through the plurality of apertures and into the tissue of the user/patient resulting in an increase in the absorption rate of the therapeutic fluid in the body of the user/patient.
