A61K 47/69 - Medicinal preparations characterised by the non-active ingredients used, e.g. carriers or inert additives; Targeting or modifying agents chemically bound to the active ingredient the non-active ingredient being chemically bound to the active ingredient, e.g. polymer-drug conjugates the conjugate being characterised by physical or galenical forms, e.g. emulsion, particle, inclusion complex, stent or kit
A61K 47/28 - Steroids, e.g. cholesterol, bile acids or glycyrrhetinic acid
A61K 47/44 - Oils, fats or waxes according to two or more groups of ; Natural or modified natural oils, fats or waxes, e.g. castor oil, polyethoxylated castor oil, montan wax, lignite, shellac, rosin, beeswax or lanolin

ORTHOPEDIC IMPLANT HAVING A CRYSTALLINE GALLIUM-CONTAINING HYDROXYAPATITE COATING AND METHODS FOR MAKING THE SAME
An orthopedic implant having a metal surface and a hydroxyapatite layer comprising gallium ions therein disposed on at least part of the metal surface is described. The hydroxyapatite layer has an average crystallite size of less than about 75 nm in at least one direction and dissolves for more than 2 hours in vitro. The hydroxyapatite layer is substantially free of carbonate. The coating, which is formed on a sodium titanate surface, has increased shear strength and tensile strength. The coating is formed by a solution deposited hydroxyapatite process under inert conditions. The pH of the solution varies by less than 0.1 pH unit/hour during coating formation.
A bone plate includes a first through hole extending through the plate along a first longitudinal axis from a proximal surface of the plate to a bone-facing distal surface thereof which, when the plate is placed on a target portion of bone in a desired orientation, faces the bone. An outer wall of the first through hole includes three wall sections provided with projections for receiving a screw head of a bone screw. The three wall sections are straight or convex.
A delivery system for deploying an implantable medical device to a target location of a body vessel can include a tubular body with a lumen extending therethrough, a pull wire extending through the lumen, and a proximal support tube disposed within the lumen and engaged to the pull wire such that proximal translation of the support tube causes proximal translation of the pull wire. The proximal support tube can include a marked distal section that is not visible to an operator of the delivery system prior to the release of the implant and that becomes visible when the proximal support tube is pulled proximally a sufficient distance to cause the delivery system to release the implant.
A61B 17/12 - Surgical instruments, devices or methods, e.g. tourniquets for ligaturing or otherwise compressing tubular parts of the body, e.g. blood vessels or umbilical cord
A61M 25/01 - Introducing, guiding, advancing, emplacing or holding catheters
