Abstract

Systems and methods for extending the life of an implanted pulse generator battery are disclosed. A representative method for establishing charge parameters for a battery-powered implantable medical device includes receiving a patient-specific therapy signal parameter and, based at least in part on the patient-specific therapy signal parameter, determining a discharge rate for a battery of the implanted medical device. The method can further include determining a therapy run time, based at least in part on the discharge rate. The method can still further include determining at least one battery charging parameter, based at least in part on the run time.

         40 . A method for establishing charge parameters for a battery-powered implantable medical device, comprising:
 receiving one or more patient-specific parameters, the one or more patient-specific parameters including at least one of a patient-specific signal delivery parameter, a patient-specific charging characteristic, or a battery specific charging characteristic;   based on the one or more patient-specific parameters, determining at least one charge parameter for the battery of the implantable medical device; and   charging the battery using the determined at least one charge parameter.   
     
     
         41 . The method of  claim 40  wherein the one or more patient-specific parameters include the patient-specific signal delivery parameter. 
     
     
         42 . The method of  claim 41  wherein the patient-specific signal delivery parameter includes at least one of a therapy signal amplitude, a therapy signal pulse width, a therapy signal duty cycle, a therapy signal on time, or a therapy signal off time. 
     
     
         43 . The method of  claim 40  wherein the one or more patient-specific parameters include the patient-specific charging characteristic. 
     
     
         44 . The method of  claim 43  wherein the patient-specific charging characteristic includes at least one of a patient-specific charging frequency or a patient-specific charging consistency. 
     
     
         45 . The method of  claim 40  wherein the one or more patient-specific parameters include the battery-specific charging characteristic. 
     
     
         46 . The method of  claim 45  wherein the battery-specific charging characteristic includes at least one of an age of the battery, a capacity of the battery, or a number of charging cycles undergone by the battery. 
     
     
         47 . The method of  claim 40  wherein the one or more patient-specific parameters include at least two of the patient-specific signal delivery parameter, the patient-specific charging characteristic, or the battery-specific charging characteristic. 
     
     
         48 . The method of  claim 40  wherein the one or more patient-specific parameters include the patient-specific signal delivery parameter, the patient-specific charging characteristic, and the battery-specific charging characteristic 
     
     
         49 . The method of  claim 40  wherein the at least one charge parameter includes an end-of charge limit. 
     
     
         50 . The method of  claim 49  wherein the end-of-charge limit includes a voltage limit at which a constant current phase of a charging process ceases. 
     
     
         51 . A method for programming a battery-powered implantable medical system, comprising:
 programming a component of the implantable medical device system with instructions that, when executed:
 receive one or more patient-specific parameters, the one or more patient-specific parameters including at least one of a patient-specific signal delivery parameter, a patient-specific charging characteristic, or a battery specific charging characteristic, 
 based on the one or more patient-specific parameters, determine at least one charge parameter for the battery of the implantable medical device, and 
 cause the battery to be charged in accordance with the at least one charge parameter. 
   
     
     
         52 . The method of  claim 51  wherein the one or more patient-specific parameters include the patient-specific signal delivery parameter. 
     
     
         53 . The method of  claim 51  wherein the one or more patient-specific parameters include the patient-specific charging characteristic. 
     
     
         54 . The method of  claim 51  wherein the one or more patient-specific parameters include the battery-specific charging characteristic. 
     
     
         55 . The method of  claim 51  wherein the one or more patient-specific parameters include at least two of the patient-specific signal delivery parameter, the patient-specific charging characteristic, or the battery-specific charging characteristic. 
     
     
         56 . The method of  claim 51  wherein the at least one charge parameter includes an end-of charge limit. 
     
     
         57 . The method of  claim 51  wherein the component of the implantable medical device system is an implantable pulse generator. 
     
     
         58 . An implantable medical device, comprising:
 a battery; and   a programmable component, the programmable component being programmed with instructions that, when executed:
 receive one or more patient-specific parameters, the one or more patient-specific parameters including at least one of a patient-specific signal delivery parameter, a patient-specific charging characteristic, or a battery specific charging characteristic, 
 based on the one or more patient-specific parameters, determine at least one charge parameter for the battery of the implantable medical device, and 
 cause the battery to be charged in accordance with the at least one charge parameter. 
   
     
     
         59 . The system of  claim 58  wherein the one or more patient-specific parameters include the patient-specific signal delivery parameter.
