摘要： A process and apparatus for dip-coating intermediate and/or discrete discontinuous portions of longitudinal devices, including medical devices such as catheters and guidewires. The apparatus provides a chamber in which both the desired portion(s) of the device and the coating solution can be controllably contacted. A controlled coating can be achieved within the chamber by providing and controlling one or more of the following relationships: a) the manner in which a chamber (containing solution) is itself moved with respect to a static device, b) the manner in which the device is moved with respect to a fixed chamber position containing a fixed volume of solution, and/or c) the manner in which both the chamber and device are fixed in position, and the coating is achieved by adding and removing a volume of solution from the chamber. The resultant movement of solution and device is intended to mimic or replicate the relative movements involved in a conventional dip-coating procedure, at least along the length of device to be coated.

摘要： Described herein is a method for coating an object with a polymer layer. The method includes contacting the object with a first solution comprising a non-polymeric grafting initiator comprising at least one photoinitiator group capable of generating a free radical active species upon absorption of electromagnetic energy, wherein the photoinitiator group is selected from the group consisting of an initiator that is insoluble in polar solvent; and a negatively charged initiator; irradiating the first solution and the object, resulting in the grafting initiator binding to the object; removing the first solution; contacting the object with a second solution comprising a polymerizable monomer having at least one free-radical polymerizable group; and irradiating the second solution and the object, wherein the non-polymeric grafting initiator acts as a photoinitiator for a free-radical polymerization reaction.
