Therapeutic treatment of disorders based on timing information
First Claim
1. A drug delivery system device for treatment of a disorder comprising in combination:
- (a) an implantable pump having at least one reservoir for storing at least one drug;
(b) a real time clock coupled to the pump and providing time-of-day information to establish whether the pump is to deliver the drug;
(c) at least one implantable catheter coupled to the pump and adapted to deliver the drug to at least one predetermined site in a body of a patient; and
(d) a sensor coupled to the pump for generating a signal indicative of whether a patient is asleep or awake, wherein the pump is responsive to the signal.

Abstract
Disclosed are techniques for operation of neurostimulation or drug delivery devices to stop treatment therapy during times when the patient does not need to be treated. Advantageously, the present invention reduces battery usage and/or drug dosage during periods when treatment therapy need not be provided. Further, the present invention slows or reduces the tolerance the patient may develop from the electrical stimulation or treatment therapy. In one embodiment, the present invention includes a timer or a real time clock for shutting off the device during periods when the patient is sleeping in accordance with a preset schedule. The present invention preferably turns off after the patient has fallen asleep and right before the patient has awakened. Alternatively, the invention may include a sensor for sensing conditions indicative of whether the patient is awake or asleep. This sensed information may also be used to determine whether the treatment therapy should be delivered or stopped.

3. In an implanted drug delivery device for treatment of a disorder having an implantable pump and at least one implantable catheter coupled to the pump, a method of automatically starting and stopping delivery of treatment therapy to a patient comprising the steps of:
-
(a) calibrating the implantable pump with at least two parameters for determining whether treatment is to be delivered, a first parameter corresponding to a first time of day indicating that the therapy is to be started and a second parameter corresponding to a second time of day indicating that the therapy is to be stopped;
(b) monitoring a timer to determine whether at least one of the parameters is satisfied;
(c) if the first parameter is satisfied, automatically initiating the implantable pump to start delivering drug treatment therapy to the patient; and
(d) if the second parameter is satisfied, automatically initiating the implantable pump to stop the delivery of the drug treatment therapy. - View Dependent Claims (4, 5)

6. A system for automatically starting and stopping delivery of treatment therapy to a patient comprising in combination:
-
(a) an implantable pump;
(b) at least one implantable catheter coupled to the implantable pump and adapted to deliver at least one drug to at least one site in a body of a patient;
(c) a timer providing timing information; and
(d) means responsive to the timer for causing the implantable pump to start delivering drug treatment therapy to the patient if the timing information satisfies a first time of day parameter and for causing the implantable pump to stop delivering drug treatment therapy to the patient if the timing information satisfies a second time of day parameter. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A system for automatically starting and stopping delivery of treatment therapy to a patient comprising in combination:
-
(a) an implantable pump;
(b) at least one implantable catheter coupled to the implantable pump and adapted to deliver the drug treatment therapy to at least one site in a body of a patient;
(c) a sensor that provides information as to whether the patient is asleep or awake; and
(d) means responsive to the sensor for causing the implantable pump to start delivering drug treatment therapy if the patient is awake and for causing the implantable pump to stop delivering drug treatment therapy if the patient is asleep. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A method of automatically starting and stopping delivery of treatment therapy to a patient with an implantable pump having at least one implantable catheter coupled to the implantable pump, comprising the steps of:
-
(a) sensing by a sensor a characteristic of the patient to determine whether the patient is awake or asleep;
(b) if the sensor indicates that the patient is awake, causing the implantable pump to start delivering drug treatment therapy to the patient; and
(c) if the sensor indicates that the patient is asleep, causing the implantable pump to stop delivering drug treatment therapy to the patient. - View Dependent Claims (23, 24, 25, 26, 27, 28)
