Abstract
A patch pump device generally includes at least one fluid source, a fluid communicator, and an electrochemical actuator. The fluid communicator is in fluid communication with the fluid source. The electrochemical actuator is operative to cause fluid to be delivered from the fluid source into the fluid communicator.

54. A device for delivering a therapeutic to a patient comprising:
-
an electrochemical actuator including a negative electrode, a positive electrode, and a species formulated to intercalate, de-intercalate, alloy with, oxidize, reduce, or plate with a first portion of the electrochemical actuator to an extent different than with a second portion of the electrochemical actuator, thereby imparting a differential strain between the first and second portions and causing a displacement of at least a portion of the electrochemical actuator; and an electrical circuit electrically coupled to the electrochemical actuator so as to allow the electrochemical actuator to discharge therethrough, the electrical circuit including only fixed resistive elements, the electrical circuit configured to allow the electrochemical actuator to discharge such that the therapeutic is delivered to the patient with linear flow. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62, 63)

64. A device for delivering a flowable material a patient comprising:
-
a delivery system including a source, a cannula, and an electrochemical actuator including an electrode configured to deflect as the electrochemical actuator undergoes a change in electrical potential, the deflection of the electrode being operative to cause the flowable material to be delivered from the source; and a housing configured for removably associating the delivery system with the body of the patient, the housing being movable between an unassembled configuration in which the delivery system is in a deactivated state, and an assembled configuration in which a first portion forms a cooperative fit with a second portion and activates the electrochemical actuator, thereby delivering the flowable material from the source through the cannula. - View Dependent Claims (65, 66, 67, 68, 69, 70)

71. A method for administering a drug to a patient, the method comprising:
-
securing a disposable infusion pump to the patient'"'"'s skin, wherein the disposable infusion pump comprises (i) a reservoir storing a fluid which includes at least one drug;
(ii) an electrochemical actuator including an electrode configured to deflect as the electrochemical actuator discharges; and
(iii) at least one fluid communicator positionable to penetrate the patient'"'"'s skin; andactivating the electrochemical actuator causing the electrode to deflect, thereby delivering fluid from the reservoir, through the fluid communicator, and into the patient. - View Dependent Claims (72, 73)
