Microcapillary Mesh Oxygen Transporter for Cell Transplantations

A two-dimensional lattice or mesh scaffold for therapeutic cell implants is disclosed as well as methods for manufacture and use. The lattice is constructed of crisscrossing capillaries of hydrophobic parylene, such as parylene AF4, that may be coated with a hydrophilic polymer, such as parylene C, for cell adhesion. At each intersection of the crisscross, the intersecting capillaries are internally connected so as to allow oxygen to flow freely within. The walls of the capillaries are thin enough to be permeable to oxygen, on the scale of a micron thick, so that oxygen can flow through the lattice and permeate through the capillary walls. For some implants, cells are sandwiched between two or more lattices, the cells being slightly held apart from aggregation with each other by the lattice holes. The implants may then be surgically implanted within a subject.

Surgical stapler with end effector coating

Methods and devices are provided for promoting wound healing. In general, surgical staplers and stapler components are provided having a coating thereon that is configured to selectively control an interaction between at least one matrix metalloproteinase (MMP) inhibitor and an outer surface of the stapler or stapler component.

Endoprosthesis
09731050 · 2017-08-15 · ·

An endoprosthesis, in particular an intraluminal endoprosthesis, for example a stent, having a basic mesh composed of an at least predominantly biodegradable material, and a coating provided on the biodegradable material is proposed. For better control of the degradation the basic mesh is essentially completely covered by a coating which contains parylene, preferably at least predominantly parylene, particularly preferably parylene C or parylene N, and the basic mesh is essentially completely covered by the coating, whereby the thickness of the coating is between approximately 0.1 μm and approximately 10 μm, preferably between approximately 0.4 μm and approximately 7 μm, particularly preferably between approximately 1 μm and approximately 5 μm. Also proposed is a method for manufacturing such an endoprosthesis.

Composition useful as an organic water/oxygen barrier material, OLED display device and manufacturing method thereof

A composition which can be used as an organic water/oxygen barrier material, an OLED display device and manufacturing method thereof are disclosed. The composition includes: 15-25 wt % of parylene, 15-25 wt % of polyvinyl chloride, 5-15 wt % of acetone, 5-15 wt % of trichloroethylene, 10-20 wt % of polyvinyl acetate, 5-15 wt % of polyvinyl alcohol, 0-5 wt % of SiO.sub.2 nanoparticles, and 8-12 wt % of an organic solvent, wherein all weight percent values are based on the total weight of the composition. When a water/oxygen barrier layer fabricated by the composition is disposed between a luminescent layer of OLED and a light extraction layer, water vapor and oxygen gas can be prevented from entering the OLED luminescent layer, thereby prolonging the service life of the OLED luminescent layer.
