The present invention relates to the use of the anti-megakaryocytic agent anagrelide, or a therapeutically active metabolite thereof, in the prevention or treatment of metastatic disease in cancer patients displaying paraneoplastic thrombocytosis.

Provided herein are bioactivated polymer/extracellular matrix (ECM) composites and methods of preparation and use thereof. In particular, heparinized cysteine-polymer/ECM composites, and methods of preparation and use thereof, are provided. In some embodiments, provided herein are compositions comprising a composite of: (a) extracellular matrix (ECM), and (b) a polyester covalently linked to a bioactive agent. In some embodiments, the composite is a homogeneous composite. In some embodiments, the ECM is decellularized ECM. In some embodiments, the ECM is not substantially crosslinked.

The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having an outer surface of a graft material thereof associated with a hydrogel composition, which may swell upon implantation within a blood vessel, thereby mediating various complications associated with endovascular procedures. The hydrogel compositions can also include various stabilizing polymers and active agents to further aid their use in the body.

The present application provides methods of functionalizing an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal or by culturing an organ or tissue in a bioreactor containing such nutrient. The present application also provides methods of selectively functionalizing extracellular matrix (ECM) of an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal. In some aspects, the present application provides a decellularized scaffold of a mammalian organ or tissue comprising an extracellular matrix, wherein the extracellular matrix of the decellularized scaffold is functionalized with a chemical group that is reactive in a bioorthogonal chemical reaction, such as an azide chemical group. The present application also provides biological prosthetic mesh and mammalian organs and tissues for transplantation prepared according to the methods of the application.

Devices, systems, and methods are provided including a structure having one or more surfaces configured for internal use within a patient's body and one or more therapeutic compositions comprising one or more active substances including a direct factor Xa inhibitor, and a direct factor IIa inhibitor disposed in or on the structure. The structure is configured to be positioned adjacent an injury site in the patient's body. The one or more active substances optionally include an anti-proliferative agent. The therapeutic composition is formulated to release the one or more active substances to the injury site to provide one or more of inhibit clot formation, promote clot dissolution, inhibit or dissolute inflammation, inhibit vessel injury, increase time before clotting, and/or inhibit cell proliferation.

High strength biomedical materials and processes for making the same are disclosed. Included in the disclosure are nanoporous hydrophilic solids that can be extruded with a high aspect ratio to make high strength medical catheters and other devices with lubricious and biocompatible surfaces.

Provided herein is a method of reducing a microbial infection of a heparinized surface wherein heparin precipitation is reduced as compared to a control. In some embodiments a composition comprising ethanol and isopropanol is applied to the surface. In other embodiments, two or more ethanol compositions are applied and removed sequentially from the surface prior to contacting the surface with a biological fluid, tissue or vessel, wherein the composition in each successive administration comprises an increased amount of ethanol. Also provided is a method of reducing a microbial infection of a surface comprising applying a mucilage extract from an Opuntia ficus indica species to the surface.

A vascular stent including at least two layers of magnesium alloy latticed support walls, a cavity, and an expandable balloon. The expandable balloon is disposed in the cavity.

Medical articles formed from ionically bonding an ionic polymer and an active agent provide enhanced properties. The ionic polymer may be one or more of an anionic polymer, a cationic polymer, and a zwitterionic polymer. The device may also include a nonionic polymer. Medical articles herein have antimicrobial, anti-fouling, and/or antithrombotic characteristics.
