Abstract: Embodiments include an infusion-occlusion system having a delivery catheter, a guide catheter adapted to receive the delivery catheter, and a guidewire with an occlusion device adapted to be received within the guide catheter. The guide catheter of the catheter kit may be provided with an occlusion device at the distal end of the guide catheter. The delivery catheter may have an accessory lumen, coaxial or co-linear lumen, a supporting mandrel, or an occlusion device at its distal end. Moreover, according to some embodiments, occlusion devices may be a single material or a composite balloon having an inner liner and an outer layer of different materials, a high compliance low pressure balloon, or a filter device that restricts particles from passing through but does not restrict fluid, such as blood. An inflation device with a large volume and low volume syringe can be used to inflate the balloon.

Abstract: An implantable medical device is disclosed having a plurality of smaller particles contained in a plurality of larger particles and configured to be released from the larger particles when the device is implanted in a patient. The smaller particles and the larger particles are made of bioabsorbable metal, glass or ceramic. A substance can be associated with the smaller particles. The larger particles can be embedded within at least a portion of the device.

Abstract: A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.

Abstract: This disclosure provides a medical device and a method of forming the medical device. The medical device comprises a coating comprising a type-one polymer and a type-two polymer. The type-one polymer comprises 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.
Abstract: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.

Abstract: Methods and devices relating to polymer-bioceramic composite implantable medical devices are disclosed. The bioceramic comprises calcium sulfate.
Abstract: A system, nozzle assembly, and method for coating a stent with a solvent and polymer are provided. The polymer can include a therapeutic substance or a drug. The polymer and solvent can be discharged from separate tubes disposed within another tube carrying moving air. The polymer and the solvent mix together when they are discharged and are atomized by the air. The ends of the tubes can be concentric with each other.
Abstract: A method of manufacturing a drug-delivery coating for a stent is disclosed. The method comprises covering the outer surface of the stent; applying a first composition to the inner surface of the stent to form a first coating; covering the first coating on the inner surface of the stent; and applying a second composition to the outer surface of the stent to form a second coating.

Abstract: With abluminal side of a stent masked, the luminal side of the stent is selectively coated with a substance, such as an anti-coagulant, a platelet inhibitor and/or a pro-healing substance. The stent can be masked by inserting it into a rigid mandrel chamber or by compressing a masking sleeve onto the outer side of the stent. A spray nozzle inserted into the masked stent spray coats the substance onto the luminal side. The sprayed coating can be cured onto the stent such as by inserting an electrical-resistance heater bar into the stent.
