Abstract
Products and methods directed to the improved infusion of fluids are disclosed. Such products and methods can be used to more efficiently and efficaciously administer therapeutic pharmaceuticals to a subject in need of treatment. In many instances, the systems comprise a therapeutic fluid delivery system and a mechanism for enhancing the absorption of the therapeutic fluid. The enhancement of the absorption of the therapeutic fluid is generally performed locally i.e., at or near the site of administration of the therapeutic fluid. The system and methods can be used to deliver any number of therapeutic fluids including but not limited to insulin.

66. A system for delivering therapeutic fluid to a body of a patient comprising:
-
a pump including; a reservoir for retaining the therapeutic fluid, a driving mechanism which dispenses the therapeutic fluid from the reservoir to the body of the patient, a controller which controls, at least in part, operation of the driving mechanism, and a power source which powers at least the driving mechanism and the controller; a first subcutaneously insertable element for delivering the therapeutic fluid therethrough to the body of the patient, the first subcutaneously insertable element comprises a distal portion configured for subcutaneous placement within the body of the patient; and an absorption enhancement device that causes an increase in the absorption rate of the therapeutic fluid in the body of the patient. - View Dependent Claims (67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)

81. A device for delivering therapeutic fluid to a body of a patient comprising:
-
a pump having a pump housing accommodating; a reservoir for retaining the therapeutic fluid, a driving mechanism which dispenses the therapeutic fluid from the reservoir to the body of the patient, a controller which controls, at least in part, operation of the driving mechanism, and a power source which powers at least the driving mechanism and the controller; a cannula having a distal end configured for subcutaneous placement and which delivers the therapeutic fluid therethrough to the body of the patient; optionally a skin adherable cradle for securing the pump to the skin of the patient; and a heating device which heats local tissue surrounding the cannula and causes an increase in the absorption rate of the therapeutic fluid in the body of the patient, wherein the heating device is disposed at one or more of the pump housing, cannula and cradle.

82. A method for enhancing absorption of a therapeutic fluid in a body of a patient, the method comprising:
-
providing a pump for delivering the therapeutic fluid to the body of the patient, the pump is associated with at least one cannula for delivering the therapeutic fluid therethrough to the subcutaneous tissue of the patient; providing an absorption enhancement device for increasing an absorption rate of the therapeutic fluid in the body of the patient; applying an absorption enhancing stimulus, via the absorption enhancement device, to a therapeutic fluid administration site; and administering the therapeutic fluid via the at least one cannula. - View Dependent Claims (83, 84, 85)
