A method to manage user access to a system containing multiple implanted medical devices, a programmer, and at least one monitoring device is desirable. Users may be assigned a role, where each role is associated with an access level to parameter sets within the devices. User roles may be managed through user groups and the associated passwords.

Managing Access to Multiple Medical Device Therapies in a System

Patients can be diagnosed with multiple conditions requiring one or more implantable medical devices (IMDs).  An IMD can be configured to perform one or more therapeutic functions, and can include, among others, cardiac rhythm management devices, cochlear implants, neural stimulation devices, or insulin or other drug pumps.  In an example, a system can contain at least one IMD, a programmer, or a monitoring device.  To maintain a device or to manage monitoring or therapies associated with the IMD, multiple users may be given access to the IMD.  Managing user access and controlling data integrity is desirable.  In an example, users can be given access to devices based on defined roles.  In an example, user access can be controlled through password protection.

User Types

                  In an example, users of the system can have defined roles.  For example, users can include the patient with an IMD, one or more physicians, or a field representative of an IMD device vendor.   In an example, a patient can be the individual with the IMD, or a person responsible for the patient such as a parent of a minor.  In an example, a physician can be responsible for a therapeutic treatment associated with the IMD, or can be responsible for treatment of one or more other health related conditions. 

Data Sets

                In an example, the IMDs can contain data sets associated with physiological conditions of the patient, device diagnostics, or programmed therapeutic activities.  For example, a pacemaker IMD can store one or more sets of physiological data associated with the patient’s cardiovascular condition, a set of parameters defining a pacing therapy, and a device diagnostic data set.  In an example, the device diagnostics for an IMD can include battery status and lead integrity.  In an example, the IMD can include one or more parameter sets associated with a prescribed therapy such as treating a bradyarrhythmia or tachyarrhythmia condition.

User Roles

                Users can be assigned to a user group based on the user’s role associated with the IMD, where a particular role corresponds to a defined set of rights to access system data.  In an example, user groups may include, but not be limited to, a patient, a primary practitioner, a clinician, an administrator, and a field representative of an IMD manufacturer.  In an example, a patient user group may include the patient, the parent of a minor patient, or a person who has been given a health care power of attorney by the patient.  In an example, a patient with an IMD configured to administer an autonomic modulation therapy (AMT) can have access to the IMD diagnostic information, but not to the programmable data sets to configure the AMT therapy.
