Abstract:
A computer assisted programming method includes ramping up a stimulation current for a plurality of contacts on a lead. Patient feedback is received while the stimulation current is being ramped up. Patient feedback indicates that the patient is beginning to feel stimulation. Based on the patient feedback, amplitude of the stimulation current that resulted in the patient feedback is recorded, and contacts are divided into groups. The contacts are activated one group at a time to the recorded amplitude. For each activated group of contacts, whether the patient can feel stimulation is determined. Thereafter, the target group that caused the patient to feel stimulation is then sub-divided into sub-groups. This process repeats a plurality of cycles until one or more contacts that caused the patient to feel stimulation are identified. The recorded amplitude is assigned as a perception threshold for the identified one or more contacts.

Abstract:
A patient feedback device for use in an electrical stimulation system is calibrated. The electrical stimulation system includes an implantable pulse generator (IPG) implanted in a patient and a patient feedback device having a force sensor. Input from the patient is sensed using the patient feedback device. At a first time, an electrical stimulus is applied with the IPG. The force sensor is monitored at a plurality of time points. A level of force sensed by the force sensor at each of the plurality of time points is recorded. A time point at which a maximum force is applied is identified, or a time point at which a minimum force is applied is identified. The first time is compared to the time point at which a minimum force is applied or the time point at which a maximum force is applied, in order to determine a patient response time.
Abstract:
A method of visualizing a user interaction with a clinician programmer is disclosed. A user engagement with respect to a screen of the clinician programmer is detected via one or more sensors associated with the screen of the clinician programmer. One or more locations on the screen of the clinician programmer corresponding to the user engagement is determined. An external monitor is communicatively coupled to the clinician programmer. The external monitor displays one or more cursors that graphically represent the one or more locations on the screen of the clinician programmer corresponding to the user engagement, respectively.
Abstract:
In response to input from a patient who is being treated by a sacral nerve stimulation therapy, an electronic diary is generated that includes a plurality of voiding responses of the patient over a period of time. The sacral nerve stimulation therapy includes electrical pulses delivered to the patient according to a first stimulation program and via a first subset of electrode contacts on a lead that is implanted in the patient. The lead has a plurality of electrode contacts that include the first subset. Based on the voiding responses in the electronic diary, a loss of efficacy of the sacral nerve stimulation therapy is detected. The sacral nerve stimulation therapy is automatically adjusted in response to the detected loss of efficacy. The automatically adjustment of the sacral nerve stimulation therapy may include either a program-based sweep or a contact-based sweep.

Abstract:
A method of programming electrodes includes automatic current balancing and lock control. A virtual representation of a lead is displayed. The lead includes a plurality of electrodes. A subset of the electrodes is selected for programming. Each of the electrodes in the subset has one of two polarities. The two polarities are anode and cathode. A first percentage of a total stimulation current is assigned to a first one of the electrodes in the subset. In response to a user input, the first percentage is fixed to the first electrode. A plurality of second electrodes in the subset that have the same polarity as the first electrode is identified. Thereafter, a respective second percentage of the total stimulation current is automatically assigned to each of the second electrodes. A sum of the first percentage and the respective second percentages is equal to 100%.
Abstract:
The present disclosure involves a method of communicating with an implantable medical device. An authentication process is performed to verify an identity of a user of a mobile computing device. A request is received from the user to access an implantable medical device via the mobile computing device. Based on the identity of the user, a first user interface suitable for the user is selected from a plurality of user interfaces that are each configured to control an implantable medical device. The plurality of user interfaces have different visual characteristics and different levels of access to the implantable medical device. The first user interface is displayed on the mobile computing device.

Abstract:
The present disclosure involves a method of determining stimulation lead placements for a healthcare professional with respect to an implant of a neurostimulator device in a target patient. A human body model is provided. A pain map is generated over the human body model in response to user input. The pain map visually represents body regions of the target patient that are experiencing pain. A dermatome map is provided. The dermatome map includes a visual correlation between regions of a human body and segments of a spinal cord. The pain map is compared with the dermatome map. Recommendations regarding the implant of the neurostimulator device are displayed in response to the comparing.
