  • Patent number: 10556060
    Abstract: Devices, systems, and techniques for programming drug delivery are described. Such techniques may account for diffusion and mixing of drug within the fluid or allow for more flexible programming options. In one example, a method may include determining one or more fluid delivery parameters (e.g., volume, flow rate, or period of time) for a fluid that is a mixture of two other fluids. The determination may be based on one or more fluid delivery parameters of the two other fluids and/or a concentration profile representing the mixing between the two other fluids. In other examples, drug delivery programming may be facilitated by the selection of various patterns and steps of drug delivery. The system may track volume of delivered fluid to maintain desired dosing of the patient.

  • Patent number: 9996669
    Abstract: Techniques for automatically identifying medical devices, e.g., implantable medical device, using wireless communications in order to communicate with the medical devices are described. For instance, a programming system securely discovers a set of medical devices which have the capacity to communicate using wireless communication links. The programming system may then apply one or more search heuristics to identify a set of discovered medical devices that are likely to be a medical device with which a user desires to interact. When the user selects the desired one of the identified medical devices, the programming system launches a device interaction application associated with the desired medical device. The user may use the device interaction application to interact with the desired medical device.

  • Patent number: 9968732
    Abstract: An implantable medical device is capable of delivering therapeutic output to a patient. A controller, programmable by a medical professional, is operatively coupled to the implantable medical device to, in part, program the therapeutic output to be delivered to the patient. The controller has an interface allowing the medical professional to graphically select an amount of the therapeutic output to be delivered to the patient in at least one of a series of discrete timer intervals. The graphic selection may be aided by the use of a light pen or other pointing device to sketch the infusion pattern. Computer programs using algorithms may be utilized to translate the information inputted through the light pen into an infusion program.

  • Patent number: 9743878
    Abstract: A medical device senses electrical activity within a patient and, in some embodiments, delivers stimulation to the patient via a plurality electrical paths, which include electrodes and associated conductors of one or more leads. The medical device determines whether a symptomatic event, such as a seizure, is detected based on the sensed electrical activity, and measures the impedance of one or more of the paths in response to the determination. If the medical device identifies a dysfunctional electrical path based on the measured impedance, the device may, as examples, disable the dysfunctional electrical path, or modify a stimulation or sensing program to not use the dysfunctional electrical path. In this manner, the medical device may identify inaccurate symptomatic event detection and, where the device delivers a therapy in response to such detection, such as stimulation via the electrical paths, avoid inappropriate therapy delivery.

  • Patent number: 9436481
    Abstract: Various embodiments concern reprogramming an implantable medical device by an external programmer to operate using a second program version, the second program version replacing a first program version in controlling operation of the implantable medical device. It can be determined whether the implantable medical device will be able to operate using the first program version to deliver therapy according to the first program version if the implantable medical device was to revert back to using the first program version. The implantable medical device can then revert to operational programming from the second program version to the first program version, the first program version saved in memory of the implantable medical device as a restore point while the implantable medical device operates according to the second program version between the reprogramming and reverting of the implantable medical device.
