  • Publication number: 20150030913
    Abstract: A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.

  • Publication number: 20140148754
    Abstract: The invention relates to a method and device for dialysis and or bulk fluid removal by generating a fibrosis chamber within a body cavity and performing dialysis or bulk fluid removal. An implantable medical device is described having a fibrosis chamber and a pump. A dialysis chamber and an optional electrodialysis unit can further be provided. An additional controller uses sensory feedback to regulate the fluid levels by altering the extracellular fluid retention within the fibrosis chamber. This device can be used for the treatment of patients with chronic kidney disease who may also be suffering from cardiorenal syndrome and hypertension.
