  • Publication number: 20170153060
    Abstract: Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion qui of the sintering electrolyte, Li-stuffed garnet seller plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.

  • Publication number: 20170020651
    Abstract: The present invention relates to treating or preventing stenosis at an anastomosis site. In one embodiment, the present invention is a stent is curved along the longitudinal axis for placement in and adjacent to the graft orifice. In a further embodiment, the stent is drug coated to allow delivery of antivasculoproliferative drugs directly to the vicinity of the graft orifice. In a further embodiment, the stent is expandable by use of an external wire. In another embodiment, the present invention is a kit comprising the specially configured stent together with a sleeve comprising a biocompatible matrix material and a pharmaceutical agent, wherein the sleeve is applied to the external surface of the vessel or graft, resulting in extravascular delivery of a pharmaceutical agent. Methods for treating or preventing stenosis at an anastomosis site by applying the extravascular sleeve and the intravascular stent are also provided.

  • Publication number: 20150335793
    Abstract: Devices and methods for reducing, eliminating, preventing, suppressing, or treating tissue responses to hemostatic devices e.g., biological sealants or vascular procedures are disclosed. The invention employs a combination of resorbable, biocompatible matrix materials and a variety of therapeutic agents, such as antiproliferatives or antibiotics, applied to a vascular puncture or incision to achieve hemostasis following diagnostic or interventional vascular catheterizations and to treat neointimal hyperplasia and stenosis. A matrix of a material such as collagen provides a reservoir of a therapeutic agent such as rapamycin (sirolimus) and its derivatives and analogs for delivery at a tissue site at risk for vasculoproliferation, infection, inflammation, fibrosis or other tissue responses.

  • Publication number: 20140039911
    Abstract: A medical savings management system, device, and method includes a computing device configured to manage medical savings, including drug therapies, to reduce healthcare costs. Users identify medications and other treatments, determine acceptable alternatives, and identify local health care providers. Users compare costs of the identified treatments from particular local providers based upon contracted discounts, manufacturer rebates, and the availability of lower cost clinical alternatives. Based on the identified treatments, health care providers, and costs, users select a preferred treatment and provider and reduce the cost of the treatment. Additional savings are realized by.by searching a larger radius for lower cost providers and by sharing discount cards using email, text messaging, and social media outlets. Users benefit from the savings and generate revenue for sponsors of the discount programs.

  • Publication number: 20080086156
    Abstract: A method and system of embolizing an organ or vessel is disclosed. An embolization device such as a coil, balloon, spheres, stents or occlusive plaques is used. The embolization device has a surface, which may be coated with composition retaining material such as a polymer, bio-polymer or non-polymer based technology that allows sustained release of drug or material from drug eluting occlusive device. For example, an anti-angiogenic composition is coated on the application surface. The embolization device is then inserted in the vessel and embolization is enhanced by the composition.
