  • Publication number: 20210012874
    Abstract: In some aspects, systems, devices, and techniques for programming a medical fluid delivery device are described. In one example, the disclosure relates to a system including a medical fluid delivery device configured to deliver a therapeutic agent to a patient, and a processor. The processor may be configured to receive a proposed therapy dosing program that defines a fluid therapy for delivery to a patient via a medical fluid delivery device for a first period of time, determine a total dosage over a second period of time, where the second period of time at least partially overlaps the first period of time, and compare the total dosage over the second period of time to a reference dosage.

  • Publication number: 20200121849
    Abstract: A medicament delivery system configured to serve as an aid in guiding a user through the procedural steps of refilling an implantable medical pump with an external refilling apparatus by tying the physical acts associated with a refill procedure to relevant information displayed on a user interface of an external programmer. The implantable medical pump may include a refillable medicament reservoir accessible via an access port having a needle detection sensor configured to detect the presence of a portion of an external refilling apparatus within the access port, and an external programmer configured to communicate with the implantable medical pump during the refill procedure, wherein sensed data gathered by the needle detection sensor is utilized by the external programmer to prompt the display of information relative to the procedural steps of the refill procedure.

  • 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: 10201305
    Abstract: An apparatus for storing data records associated with a medical monitoring event in a data structure. An implanted device obtains data and stores the data in the data record in a first data structure that is age-based. Before an oldest data record is lost, the oldest data record may be stored in a second data structure that is priority index-based. The priority index may be determined by a severity level and may be further determined by associated factors. The implanted device may organize, off-load, report, and/or display a plurality of data records based on an associated priority index. Additionally, the implanted device may select a subset or composite of physiologic channels from the available physiologic channels based on a selection criterion.

  • 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.
