Drug delivery device
First Claim
1. A drug delivery device comprising:
- a disposable housing having an interior surface defining an interior space, and an exterior surface;
a needle having a retracted state wherein the needle is withdrawn inside of the interior space and a deployed state wherein a pointed end of the needle projects beyond the exterior surface of the housing;
an injector coupled to the needle to move the needle between the retracted and deployed states;
a reservoir disposed within the interior space, the reservoir configured to receive a volume of a drug and to be in fluid communication with the needle; and
a controller coupled to the injector and the reservoir, the controller being configured to actuate the injector to move the needle from the retracted state to the deployed state only once, to only once determine when a preselected time period has elapsed after initiation of action of the controller, and to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus after the preselected time period has elapsed after the initiation of the action of the controller, the controller disposed within the interior space and configured prior to being disposed within the interior space,wherein the delivery device is wearable, disposable, and single-use.

Abstract
A drug delivery device includes a housing having an interior space, a needle having retracted and deployed states, an injector to move the needle between retracted and deployed states, and a reservoir disposed within the interior space, the reservoir configured to receive a volume of a drug and to be in fluid communication with the needle. The drug delivery device also includes a controller coupled to the injector and the reservoir, and configured to actuate the injector to move the needle from the retracted state to the deployed state only once, and to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus after a preselected time period has elapsed, the controller disposed within the interior space and configured prior to being disposed within the interior space. The delivery device is wearable, disposable, and single-use.

27. A method of operation of a wearable, disposable, single-use drug delivery device, the method comprising:
-
initiating a controller contained within an interior space defined by a housing of the delivery device; automatically injecting a pointed end of a needle from the interior space into the patient to define an injection site only once according to the controller; determining, only once with the controller, when a preselected time period has elapsed after initiation of the controller; and automatically actuating a reservoir to deliver a volume of a drug to the patient through the injection site as a single bolus after the preselected time period has been determined to have elapsed according to the controller. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A wearable, single-use drug delivery device comprising:
-
a disposable housing having an interior surface and an exterior surface, the interior surface defining an interior space; a needle movable between a retracted position where the needle is withdrawn inside of the interior space of the housing and a deployed position where a pointed end of the needle projects from the exterior surface of the housing; a catheter or soft cannula surrounding the needle; an injector enclosed within the interior space of the housing and configured to move the needle between the retracted position and the deployed position; a reservoir enclosed within the interior space of the housing and in fluid communication with the needle, the reservoir being configured to receive a volume of a drug; and a controller operatively connected to the injector and the reservoir, the controller being configured to only once;
(i) actuate the injector to move the needle from the retracted position to the deployed position, (ii) insert the catheter or soft cannula into subcutaneous tissue of a patient, (iii) move the needle from the deployed position to the retracted position, (iv) determine when a preselected time period has elapsed after actuation of the injector to move the needle from the retracted position to the deployed position, and (v) actuate the reservoir to deliver the volume of the drug to the patient via the needle as a single bolus. - View Dependent Claims (42)
