Abstract: This disclosure covers polymers, which are useful in medical device applications. The polymers comprise at least two different blocks, at least one L1 block with the formula and at least one L2 block with the formula Medical devices comprising these polymers, mixtures of these polymers with therapeutic agents, and methods of making these polymers and mixtures are within the scope of this disclosure. Some of these medical devices are implantable within a mammalian body, such as in a body lumen.
Abstract: A method and system for making a composition for use in manufacturing an implantable medical device, such as a drug-eluting and/or delivery stent, is described. The method includes introducing a polymer, active agent, and a solvent into a mixing apparatus such as an extruder. The polymer, active agent, and solvent may be mixed in the apparatus to form a homogeneous or substantially homogeneous polymer mixture. The method may further include controlling a temperature of the polymer mixture in at least a portion of the apparatus. In an embodiment, the polymer mixture may be used as a coating for an implantable medical device, or fabricating an implantable medical device. The invention also includes a composition formed by the method described above.
Abstract: An apparatus and method to perform therapeutic treatment and diagnosis of a patient's vasculature through the use of an intravascular device having an optical fiber disposed therein. In an embodiment, the apparatus includes an intravascular device to perform a therapeutic treatment and at least one optical fiber disposed through the intravascular device. The optical fiber is configured to provide diagnostic information before, during, and after the therapeutic treatment. In an embodiment, diagnostic information includes vessel and blood characteristics such as hemodynamic characteristics, hematological parameters related to blood and blood components, and thermal parameters of the vasculature.

Abstract: The disclosure contains a medical article comprising a polymer containing polyesters and, optionally, agents for use with medical articles and methods of fabricating the same are disclosed. The medical article generally comprises an implantable substrate having a coating, and the coating contains a polymer comprising a polymeric product of a reaction comprising a polyol and a polycarboxylic acid.
Abstract: An apparatus and method for coating abluminal surface of a stent is described. The apparatus includes a stent support, a coating device, and an imaging system. The coating device includes a solution reservoir and transducer assembly. The transducer assembly includes a plurality of transducers and a controller. Each transducer is used to generate focused acoustic waves in the coating substance in the reservoir. A controller is communicated to an image system to enable the transducers to generate droplets on demand and at the predetermined ejection points on the surface of the coating substance to coat the stent. A method for coating a stent includes stent mounting, stent movement, and droplet excitation.
Abstract: A random or a block copolymer which includes at least one biologically compatible structural moiety and at least one biologically active moiety is disclosed. The random or block copolymer can be used for fabricating a coating for an implantable medical device such as a stent.

Abstract: A catheter having an elongated shaft with a proximal end, a distal end, and at least one lumen, and a distal portion of the shaft being at least in part within an outer sheath having a wedge-shaped distal end. In one embodiment, the outer sheath around the distal end of the shaft is the distal skirt section of the balloon. In an alternative embodiment, the outer sheath is a sleeve member having at least a portion located distal to the distal end of the balloon.

Abstract: A sleeve is positioned over a radially-expandable rod assembly and a stent is positioned over the sleeve. A mandrel is inserted into the rod assembly to thereby press the sleeve against the inner surface of the stent and expand the stent. A coating (such as a solvent, a polymer and/or a therapeutic substance) is then applied to the outer (abluminal) surfaces of the stent, by spraying, for example. The sleeve advantageously prevents the coating material from being applied to inner (luminal) surfaces of the stent and also allows the coating material to be efficiently applied to the abluminal surfaces.
