Drug coating layer and method for forming same
A drug coating layer that prevents breakage of elongated drug crystals on a balloon surface while maintaining the drug crystals in an appropriate shape to act on the living body includes plural elongated bodies which are crystals of a water-insoluble drug each extending from the surface of the balloon at various lengths and angles, and a water-soluble additive layer provided in a space between an outer surface of an aggregate of the elongated bodies and the balloon surface to fill a space between the elongated bodies. The outer surface of the additive layer being located outside the aggregate, being uneven connecting a plurality of tip ends and side surfaces of the elongated bodies to each other. The tip ends of the elongated bodies slightly protrude from the additive layer, and the side surfaces and/or tip surfaces of the elongated body are exposed on the surface of the additive layer.
Alternative use for hydrogel intrasaccular occlusion device with vertically oriented reinforcement members for structural support
A device for endovascular treatment to ameliorate aneurysm recurrences by deploying a treatment mesh having a plurality of vertically oriented elongated support reinforcement elements that are substantially parallel and oriented upon a plane in communication with the mesh. Upon deployment, the array of distal ends of the support extensions and reinforcements are substantially oriented upon a plane, which plane is in substantially the same orientation as the opening of the aneurysm into which the device was deployed. The treatment mesh may incorporate a coating of hydrogel, optionally impregnated with pharmaceutical compounds.
SELF-LUBRICATING MEDICAL ARTICLES
Medical articles formed from a polyurethane-based resin including a modifying oligomer provide enhanced properties. A modifying oligomer incorporated into a backbone, as a side chain, or both of the polyurethane-based resin formed by a diisocyanate, a polyglycol, and a diol chain extender has at least one, preferably two, alcohol moieties (C—OH) and a functional moiety. Exemplary modifying oligomers are: a diol-containing perfluoropolyether incorporated into the backbone, a monofunctional polysiloxane (e.g., monodialcohol-terminated polydimethylsiloxane) incorporated as the side chain, and combinations thereof. Medical articles herein are self-lubricating and/or anti-fouling.

XYLITOL-DOPED CITRATE COMPOSITIONS AND USES THEREOF
The present disclosure provides compositions which may be used as tissue engineering materials, and more particularly xylitol-doped citrate polymer compositions which may be useful as bone grafts.
THERAPEUTIC AGENT DELIVERY SYSTEMS AND METHODS OF FORMING AND USES THEREOF
A novel therapeutic agent delivery system, methods of use and methods of formation thereof are presented. The novel delivery system is comprised of novel nanoparticles capable of at least partially encapsulating a therapeutic agent such as an anesthetic, antimicrobial, growth factor or protein. The nanoparticles are embedded with in a crosslinked hydrogel. The hydrogel can be administered directly to a patient or may be coated onto a device such as a catheter. The delivery system allows for a sustained release of the therapeutic agent over an extended period of time.
Treatment for hydrocephalus
A shunt system used to treat excess cerebrospinal fluid (CSF) accumulation is described. In some embodiments, the system utilizes various mechanical, electrical, or electromechanical concepts designed to either clean a portion of the shunt system, or customize CSF drainage.
Blow molded composite devices and method
The present disclosure is directed toward a composite balloon comprising a layer of material having a porous microstructure (e.g., ePTFE or expanded polyethylene) and a thermoplastic polymeric layer useful for medical applications. The layers of the composite balloons become adhered through a stretch blow-molding process. Methods of making and using such composite balloons are also described amongst others.
Device having a switchable wet-dry lubricating coating
A lubricating coating including at least one polymer A, a cross-linker and at least one lubricating agent, and wherein a portion of the at least two reactive groups of the cross-linker are covalently linked to the polymer A to form a three-dimensional network in which the lubricant is incorporated, and wherein at the same time another portion of the reactive groups of the cross-linker are covalently linked to the surface of the device or to the optional adhesion layer on the surface of the device.
