  • Patent number: 9770438
    Abstract: Effective treatments of acute pain for extended periods of time are provided. The treatments include the administration of one or more drug depots at or near a target site wherein the drug depots include an effective amount of clonidine formulated within a polyorthoester. By administration of one or more drug depots at or near the target site, one can relieve pain caused 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. In some embodiments, the relief can be for at least twenty-five days, at least fifty days, at least one hundred days or at least one hundred and thirty-five days.

  • Patent number: 9707338
    Abstract: An ambulatory infusion device includes a common module having a pump mechanism and a fluid flow path in communication with the pump mechanism. The device also includes a custom module operably coupleable to the common module. The custom module includes a reservoir for housing a liquid composition comprising a medicament and control electronics. The reservoir is configured to fluidly couple with the fluid flow path, and the control electronics are configured to electrically couple to the pump mechanism when the common module and the custom module are operably coupled. When the common module and the custom module are operably coupled, the pump mechanism is configured to drive the liquid composition from the reservoir to a patient via the fluid flow path, and the control electronics are configured to control the rate at which the pump mechanism drives the liquid composition.

  • Patent number: 9463889
    Abstract: Prefilled reservoir apparatuses for use in ambulatory infusion devices include a rigid top and a flexible bag that forms at least a portion of a reservoir containing a liquid medicament composition. The reservoir apparatuses include a septum assembly that includes a fluid flow path in communication with the reservoir and a self-sealing septum disposed in or over the fluid flow path. The septum is positioned and configured to be pierced by a cannula of a base of an infusion device when the reservoir apparatus is received by the base.

  • Patent number: 8348884
    Abstract: A sympatholytic cardiovascular agent delivered by a drug delivery pump to a central nervous system site to alleviate symptoms of acute or chronic cardiac insult or impaired cardiac performance. The drug delivery pump can be external or implantable infusion pump (IIP) coupled with a drug infusion catheter extending to the site. A patient activator can command delivery of a dosage and/or an implantable heart monitor (IHM) coupled with a sensor can detect physiologic parameters associated with cardiac insult or impaired cardiac performance and trigger dosage delivery. The IIP and IHM can be combined into a single implantable medical device (IMD) or can constitute separate IMDs that communicate by any of known communication mechanisms. The sympatholytic cardiovascular agent is one of the group consisting of an alpha-adrenergic agonist and an alpha2-adrenergic agonist (e.g.
