  • Publication number: 20150110849
    Abstract: An antimicrobial accessory may include a pressure sensitive adhesive and an antimicrobial mixed in the pressure sensitive adhesive. In some examples, an antimicrobial accessory may include at least one first domain comprising a pressure sensitive adhesive and a first antimicrobial and at least one second domain including a second polymer and a second antimicrobial. The antimicrobial accessory may be configured to be attached to a housing of an implantable medical device (IMD).

  • Patent number: 9014815
    Abstract: A medical device lead is presented that includes an electrode assembly having a first electrode located near a distal end of the electrode assembly and a second electrode located near a proximal end of the electrode assembly. The electrode assembly also includes a conductive elongated coupler that is electrically coupled to the first electrode and capacitively coupled to the second electrode. At low frequencies and DC (e.g., during delivery of stimulation therapy), the capacitive coupling between the conductive elongated coupler and the second electrode presents a high impedance allowing little current to be redirected from the first electrode to the second electrode. However, at high frequencies (e.g., during an MRI scan) the capacitive coupling between the conductive elongated coupler and the second electrode presents a low impedance, resulting in a significant amount of induced current being redirected to the second electrode and dissipated into bodily fluid surrounding the second electrode.

  • Patent number: 8911427
    Abstract: A therapeutic agent reservoir comprises a reservoir body comprising a polymer and a therapeutic agent mixed within the polymer, and an outer coating enclosing the reservoir body, wherein at least a portion of the outer coating comprises a rate-controlling membrane configured to provide a predetermined release rate of the therapeutic agent through the rate-controlling membrane.

  • Patent number: 8409219
    Abstract: A method of placing an electrical lead of an implantable cardiac device inside a heart of a patient. The method includes securing a tool to an atrial appendage of the heart to hold onto the atrial appendage, piercing the atrial appendage, and creating an aperture in the atrial appendage while holding the atrial appendage with the tool. The method also includes moving a distal end of the electrical lead into the heart through the aperture in the atrial appendage and into a ventricle of the heart. Furthermore, the method includes coupling the distal end of the electrical lead to cardiac tissue in the ventricle and delivering an electrical signal to the cardiac tissue in the ventricle of the heart to maintain a predetermined heartbeat of the heart.

  • Publication number: 20110123517
    Abstract: A pharmaceutical implant may include a pharmaceutical and at least one excipient, and may be configured to be implanted in a body of a patient. The at least one excipient may dissolve after implantation of the pharmaceutical implant in the body of the patient and release the pharmaceutical. In some examples, the pharmaceutical implant includes at least two pharmaceuticals. The at least one excipient may be selected to provide a desired release profile of the pharmaceutical. For example, the pharmaceutical implant may be configured to dissolve and release the pharmaceutical over a length of time between about one day and about 30 days. In some examples, the pharmaceutical implant may be implanted in the body of the patient proximate to an implantable medical device.
