  • Publication number: 20140088442
    Abstract: A medical monitoring device for monitoring electrical signals from the body of a subject is described. The medical monitoring device monitors electrical signals originating from a cardiac cycle of the subject and associates each cardiac cycle with a time index. The medical monitoring device applies a forward computational procedure to generate a risk score indicative of hyperkalemia, hypokalemia or arrhythmia of the subject. The medical monitoring device can adjust the forward computational procedure based upon clinical data obtained from the subject.

  • Patent number: 8673339
    Abstract: A biostable polymeric substrate of an implantable medical device unit includes a demand-release bioactive composition including one or more bioactive agents covalently bound to surface-modifying end groups of the substrate. Certain cellular activities, in proximity to the polymeric substrate, release substances reacting with the end groups such that the end groups release the one or more bioactive agents, which modify the certain cellular activities.

  • Publication number: 20130261095
    Abstract: Effective treatments of acute pain for extended periods of time are provided. Through the administration of an effective amount of dexamethasone at or near a target site, one can relieve pain cause by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discongenic back pain and joint pain as well as pain that is incidental to surgery. When appropriate formulations are provided within biodegradable polymers, this relief can be continued for at least twenty-five days. In some embodiments, the relief can be for at least fifty days, at least one hundred days, at least one hundred and thirty-five days or at least one hundred and eighty days.

  • Publication number: 20110269720
    Abstract: Methods and kits for treating infection associated with implantation of a medical device use of minocycline and rifampin microparticles. The microparticles, in a suitable medium, can be injected in a patient in proximity to the device. The drugs may be configured to be released from the polymer matrix in a controlled manner by manipulation of the properties of the polymer forming the microparticle. By injecting the drugs in the form of microparticles, the drugs can be distributed in a manner so that the entire pocket is protected without affecting device function. The microparticles can be produced aseptically without affecting the manufacturing of the device.
