A stent for placement in a blood vessel with a wall having an aneurysm including an endovascular graft having a first end, a second end, and a tubular body that is expandable and extends from the first end to the second end. The stent also includes a coagulation apparatus attached to the tubular body between the first and second ends. The coagulation apparatus has a frame and a coagulant attached to the frame. When the stent is deployed within the blood vessel, the tubular body extends across the aneurysm and expands at the first and second ends to seal against the wall of the blood vessel such that blood is channeled across the aneurysm through the tubular body such that a pocket of blood is defined external to the tubular body. The frame expands into the pocket to orient the coagulant therein and promote coagulation of blood within the pocket.

Device and method of inhibiting endoleaks

Disclosed herein is a device and method for regenerating tissue using a modular scaffold having a gradient of enzymatic degradability. The disclosure further relates to scaffolds made of microparticles comprising a cross-linked water-soluble polymer or cross-linked water-soluble polymers and a process for forming thereof.

Hydrogel microparticle scaffold with gradients of degradability and methods thereof

The invention generally relates to substrates and surfaces having substrates. Generally speaking, the substrates may be thinly layered substrates, and the surfaces may comprise thinly layered substrates. Additionally, the substrates may comprise a multifunctional water soluble polymer and a lipoprotein and the surfaces may comprise a multifunctional water soluble polymer and a lipoprotein.

Biomaterials having nanoscale layers and coatings

The field of the disclosure relates to microparticles comprising a cross-linked water-soluble polymer or cross-linked water-soluble polymers and a process for forming thereof. Further, the field of the disclosure relates to coatings and scaffolds comprising microparticles and the processes for forming thereof.

Hydrogel microparticle formation in aqueous solvent for biomedical applications

The invention features polymeric biomaterials formed by nucleophilic addition reactions to conjugated unsaturated groups. These biomaterials may be used for medical treatments.

Biomaterials formed by nucleophilic addition reaction to conjugated unsaturated groups

The present invention is generally directed to composite materials or charge rolls comprising a sleeved foam charge roll where the sleeve is interference-fit over the foam core, and methods of constructing them. The foam core can be made with an outer diameter larger than that of the sleeve inner diameter. The sleeve can be interference fit over the foam core to provide a functional charge roll. In some embodiments the charge roll can be used in an image forming apparatus including, but not limited to, an electrophotography system, an electrophotographic copying machine, and a laser printer.

Conjugate addition reactions for the controlled delivery of pharmaceutically active compounds

Compositions for coating biological and non-biological surfaces, which minimize or prevent cell-cell contact and tissue adhesion, and methods of preparation and use thereof, are disclosed. Embodiments include polyethylene glycol/polylysine (PEG/PLL) block or comb-type copolymers with high molecular weight PLL (greater than 1000, more preferably greater than 100,000); PEG/PLL copolymers in which the PLL is a dendrimer which is attached to one end of the PEG; and multilayer compositions including alternating layers of polycationic and polyanionic materials. The multi-layer polymeric material is formed by the ionic interactions of a polycation and a polyanion. The molecular weights of the individual materials are selected such that the PEG portion of the copolymer inhibits cellular interactions, and the PLL portion adheres well to tissues. The compositions and methods are useful, for example, in inhibiting formation of post-surgical adhesions, protecting damaged blood vessels from thrombosis and restenosis, and decreasing the extent of metastasis of attachment-dependent tumor cells. The compositions and methods are also useful for coating non-biological surfaces such as metallic surfaces.

Multifunctional polymeric tissue coatings

The invention discloses materials that adsorb readily to the surfaces of body tissues in situ and provide a steric barrier between such tissues, so that tissue adhesions, which typically form following surgical procedures, are minimized. These materials contain a polymer of hydrophilic molecules such as polyethylene glycol (PEG) bound to a polymer that spontaneously adsorbs to biological tissue such as phenylboronic acid (PBA). The PEG-PBA co-polymer can be formed in a variety of geometries. The materials can also be used to coat prosthetics and other implants.

Methods and compositions to prevent formation of adhesions in biological tissues
