  • Publication number: 20190255302
    Abstract: Systems and methods and devices are provided for arresting or reversing the effects of myocardial remodeling and degeneration after cardiac injury, without the potential drawbacks associated with previously existing systems and methods, by at least partially occluding flow through the superior vena cava over multiple cardiac cycles, and more preferably, by adjusting the interval or degree of occlusion responsive to a sensed level of patient activity. In some embodiments, a controller is provided that actuates a drive mechanism responsive to a sensed level of patient activity to provide at least partial occlusion of the patient's superior vena cava, while a data transfer circuit of the controller provides bi-directional transfer of physiologic data to the patient's smartphone or tablet to permit display and review of such data.

  • Publication number: 20190126014
    Abstract: Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

  • Patent number: 10258284
    Abstract: An implant sized and shaped to be endovascularly delivered to the middle meningeal artery includes a carrier that carries a payload between first and second ends thereof. An anchor mechanism associated with the implant transitions into a swollen state in response to exposure to bodily fluids. In the swollen state, said anchor mechanism anchors the implant to the middle meningeal artery. Before or during the transition, the anchor mechanism permits endovascular delivery of the implant to the middle meningeal artery.

  • Publication number: 20190000885
    Abstract: Aspects of the technology disclosed herein generally (and in part) relates to use of Angiogenin (ANG) for increasing hematopoietic reconstitution of in vivo hematopoietic cells and transplanted hematopoietic cells. Provided herein are methods and compositions useful in treatment of diseases characterized by decreased levels of hematopoietic cells, decreased levels of hematopoietic reconstitution, blood cell deficiency and prevention and treatment of radiation injury. One aspect relates to angiogenin treated hematopoietic cell compositions and methods of their use in stem cell transplantation. Treatment of hematopoietic cells with angiogenin enhances quiescence and reduces proliferative capacity of primitive hematopoietic stem cells while increasing proliferation of myeloid restricted progenitor cells. Another aspect relates to use of ANG in prophylactic and therapeutic treatment methods for radiation injury.

  • Publication number: 20170065668
    Abstract: Matrix metalloproteases (MMPs) play many important roles in normal and pathological remodeling processes including atherothrombotic disease, inflammation, angiogenesis and cancer. This invention relates to the activation of protease-activated receptor-1 (PAR-1) by endogenous platelet MMP-1 collagenase on the surface of platelets. Exposure of platelets to fibrillar collagen converts the surface-bound pro-MMP-1 zymogen to active MMP-1, which promotes aggregation through PAR-1. MMP-1 is shown to cleave the PAR-1 extracellular domain at a novel site, which then strongly activates Rho-GTP signaling pathways, cell shape change and motility, and MAPK signaling. Blockade of MMP-PAR1 suppresses thrombogenesis under arterial flow conditions and inhibited thrombosis in animals. These studies provide a link between matrix-dependent activation of metalloproteases and platelet-G protein signaling and identify MMP-1/PAR-1 as a new target for the treatment and prevention of arterial thrombosis and other thrombotic diseases.

  • Patent number: 9468666
    Abstract: Endoglin has now been shown to be an important target of therapy to reduce disease symptoms associated with heart failure, particularly cardiac fibrosis. Soluble Endoglin is identified as an anatogonist to TGF?1 activity, while membrane-bound Endoglin is identified as a necessary component to promote TGF?1 activity in heart failure. The present invention therefore features methods and kits for treatment of subject having heart failure or a related disorder by administering a composition that decreases TGF?1 signaling through either direct inhibition of membrane-bound Endoglin or promoting expression of soluble Endoglin.
