Variable output ramping for an implantable medical device
First Claim
1. A method for providing an electrical neurostimulation therapy to a patient using an implantable medical device, comprising:
- determining a first rate of change of an amplitude of a first ramping portion of an electrical signal, wherein the first ramping portion is a portion where the amplitude is changed prior to delivery of a therapeutic level of stimulation;
delivering the electrical signal comprising the first ramping portion with the first rate of change of the amplitude and the therapeutic level of stimulation to a target location of a patient'"'"'s body;
analyzing efficacy data of the therapy applied using the electrical signal;
modifying the electrical signal by modifying the first rate of change of the amplitude of the first ramping portion using the efficacy data to create a modified electrical signal with the therapeutic level of stimulation and a modified ramping portion comprising a second rate of change of the amplitude;
delivering the modified electrical signal with the modified ramping portion and the therapeutic level of stimulation to the target location of the patient'"'"'s body.

Abstract
A method, system, and apparatus for providing a stimulation signal comprising a variable ramping portion using an implantable medical device (IMD). The first electrical comprises a first ramping portion. The first ramping portion comprises a first parameter and having a first value. The first electrical signal is applied to a target location of the patient'"'"'s body. A second electrical signal comprising a second ramping portion is generated. The second ramping portion comprises the first parameter having a second value that is different from the first value. The second electrical signal is applied to a target location of the patient'"'"'s body.

8. A method for providing an electrical neurostimulation therapy to a patient using an implantable medical device, comprising:
-
determining a characteristic of a ramping portion of a stimulation signal comprising the ramping portion and a therapeutic level of stimulation, wherein the characteristic of the ramping portion is provided by the implantable medical device using efficacy data of a treatment applied using the stimulation signal, the characteristic selected from a group including a rate of change of a pulse width, and a rate of change of a frequency, wherein the first ramping portion is a portion where the characteristic of the ramping portion is varied prior to delivery of the therapeutic level of stimulation; and providing the stimulation signal based upon the characteristic of the ramping portion. - View Dependent Claims (9)

10. An implantable medical device for providing an electrical neurostimulation therapy to a patient, comprising:
-
a stimulation unit to provide a first electrical signal comprising a first ramping portion and a therapeutic level of stimulation, the first ramping portion comprising a first characteristic selected from a group including a rate of change of a pulse width or a rate of change of a frequency, wherein the first ramping portion is a portion where the first characteristic is changed prior to delivery of the therapeutic level of stimulation; and a controller operatively coupled to the stimulation unit, wherein the controller determines the first characteristic using efficacy data of a treatment applied using the first electrical signal and controls a first value of the first characteristic of the first ramping portion. - View Dependent Claims (11, 12, 13, 14, 15, 16)
