摘要： An electropolishing apparatus and method are provided for polishing stents and other medical implants. The apparatus includes a motor that rotates a roller. The roller continuously rotates the medical implant to be electropolished. One of the advantages of the apparatus and method is that marks generated around the electrical contact between the anode and the medical implant are minimized. In addition, the medical implant is polished more evenly than conventional electropolishing systems.

摘要： A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with one or more dilation elements that extend along a surface of a balloon. Each dilation element is connected to an outer surface of the balloon by a connector. The connector is sufficiently sized and designed to undergo stress-induced plastic deformation incurred during blow molding so that a significant portion of each of the dilation elements does not become absorbed into the wall of the final blow molded balloon, thereby maintaining the structural integrity of each of the dilation elements.

摘要： Coaxial balloon catheters are described herein. The balloon catheter can include outer and inner tubes in a coaxial relationship, with a balloon attached to an end thereof. A support sleeve can be disposed around the inner tubular member proximate the proximal end of the balloon. The support sleeve can have a channel formed therein to communicate with an inflation lumen and a balloon interior. The channel may be formed by separation of two longitudinal edges extending through the support sleeve. The support sleeve can include an outward extending portion that is sized to engage the distal end of the outer tube in order to limit relative movement between the inner and outer tubes. The support sleeve can be configured to orient the inner tube eccentrically or concentrically relative to the outer tube. The support sleeve can have an elongate body that can be extended in proximal or distal direction.

摘要： A stent graft delivery system (50) has a stent graft (74) retained on it. The stent graft has an exposed proximally extending self expanding stent (76) which is retained in a distally opening capsule (78) at the distal end of a nose cone dilator (58) on the delivery system. A trigger wire (80) extends from a release mechanism (82) the distal end of the delivery system into a first aperture (84) in the capsule, around a proximal bend (86) of the exposed stent and out of the first aperture in the capsule and extending proximally into a second aperture (88). The trigger wire prevents premature release of the exposed stent.

摘要： A swaged braided catheter (30) for use in various medical procedures is provided. The swaged braided catheter includes a tubular braid (32) formed from a plurality of braided wire members (38). A plurality of intersections (40) is formed by the braided wire members. The intersections are compressed defining a plurality of flattened regions along the tubular braid. The intersections have a first thickness (d1) before being compressed and a reduced second thickness (t2) after being compressed. The flattened regions with the reduced second thickness provide the swaged braided catheter with a reduced cross-sectional profile, and reduced catheter recoil.

摘要： This disclosure relates to implantable medical devices coated with a taxane therapeutic agent, such as paclitaxel, in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous and/or solvated solid forms of taxane therapeutic agents that provide durable coatings that release the taxane over a desired period of time, which can be varied in the absence of a polymer by selecting the type and amount of solid forms of the taxane therapeutic agent in the coating. Other preferred embodiments relate to methods of coating medical devices and methods of treatment. The coatings can provide a sustained release of the taxane therapeutic agent within a body vessel without containing a polymer to achieve the desired rate of paclitaxel elution.

摘要： A balloon catheter with a rod embedded within a catheter shaft is provided. The catheter shaft can have a polymer filled solid body with an inflation lumen and a guidewire lumen extending at least partially therethrough. A balloon member can be attached to a distal end of the shaft. The embedded rod is extended through at least a portion of the polymer filled solid body along the inflation and guidewire lumens. The rod is preferably in non-translatable contact with the shaft body. The rod can be disposed within the balloon region of the shaft to increase the tensile strength of that region. To increase pushability and tractability of the balloon catheter, the rod may include a first length with a diameter and a second length with a lesser diameter, with a tapered region interposed between the first and second lengths.
