Abstract: A method of radiation sterilizing a plurality of stent-catheter assemblies includes positioning a plurality of stent-catheter assemblies on a fixture, each of the stent catheter assemblies being arranged in a planar configuration and disposed in corresponding planar packages supported on the fixture, wherein the packages are stacked horizontally on the fixture, and wherein the stents of the assemblies are positioned at a position in each package such that the stents are exposed to the same or substantially the same radiation; and exposing the packages to an incoming radiation beam, the radiation beam being at an acute angle to the planes of the planar configuration of the assemblies, wherein the packages are arranged such that a front end of the stack faces the radiation beam and a back end of the stack faces away from the radiation beam.

Abstract: Method are disclosed for local and systemic administration HDL, recombinant HDL or HDLm for the prevention, treatment, or amelioration of a vascular disorder, disease or occlusion such as restenosis or vulnerable plaque.
Abstract: A method of coating an implantable medical device is disclosed, the method includes applying a composition onto the device and drying the composition at elevated temperature in an environment having increased relative humidity.
Abstract: A porous prosthesis for delivering a medication to the site of implantation. The prosthesis, such as a stent, includes a first porous region and a second porous region and is at least partially formed from a molybdenum-rhenium alloy. The porous regions can have different porosity. A stent includes first, second and third porous region, the first porous region being between the second and third porous regions, and a therapeutic agent is disposed in the first porous region. A stent can also include a solid core and inner and outer porous layers surrounding the core.
Abstract: Polymers containing poly(hydroxyalkanoates) and 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 poly(hydroxyalkanoate).
Abstract: Coatings for an implantable medical device and a method of fabricating thereof are disclosed, the coatings comprising a biologically degradable, biologically erodable, and/or biologically resorbable ABA or AB block copolymer. A biologically active agent can be conjugated to the block copolymer.

Abstract: The present invention provides a square-wave laser seal pattern made by first directing a laser beam onto an shaft while the shaft is moving in a horizontal direction relative to a laser device so as to create a horizontal laser seal bond segment. Next, with the shaft rotating about a shaft longitudinal axis, the laser beam is directed onto the shaft so as to create a vertical laser seal bond segment. By alternately creating and coupling together a plurality of horizontal and vertical laser seal bond segments, a square-wave laser seal is formed around a circumference of the shaft. The shaft's movement in a horizontal direction relative to a laser beam may be either at a constant speed or a variable speed so as to control the amount of laser energy heat impacting the shaft material.
Abstract: Disclosed herein is a stent comprising: a bioabsorbable polymeric scaffolding; and a coating comprising a bioabsorbable material on at least a portion of the scaffolding, wherein the degradation rate of all or substantially all of the bioabsorbable polymer of the scaffolding is faster than the degradation rate of all or substantially all of the bioabsorbable material of the coating.
Abstract: A method for modifying a polymeric coating on an implantable medical device, such as a stent, is disclosed. The method includes application of a fluid to a wet or dry polymeric coating with and without drugs.
