摘要： A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to provide a reference for positioning the device at a location distal to the interventional procedure site, and to enable an end of the device to be in tension, enabling a portion of the device to be in tension and another portion to be in compression, so as to assist in bending thereof in tortuous vasculature.

摘要： A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly. The guide wire connector is able to couple with the helical coil of the guide wire. A restraining sheath placed over the filter assembly in a coaxial arrangement maintains the filter assembly in a collapsed position and delivers the filter assembly separately to the helical coil of the guide wire, and then the guide wire connector is joined to the helical coil. Alternatively, the guide wire can include a rotatable coil section forming a portion of the distal tip coil on the guide wire which is adapted to be coupled to the filter assembly. This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.

摘要： A cage and sleeve assembly for an embolic filtering device used to filter embolic particles from a body vessel has a strut assembly that is movable between an unexpanded position and an expanded position. Struts having strut ends at the respective ends form a cage. The strut ends are initially made from linear elastic nitinol, and a series of spot or laser or other types of welds then secure the strut ends in the sleeve assembly. In one approach, the ends of the strut ends are welded to form a tube. In another approach, the strut ends are welded onto a sleeve. The strut ends may optionally have ends that are partial cylinders, and the partial cylinders are welded onto a cylindrical sleeve. Effects from the welding, such as changing linear elastic nitinol to superelastic nitinol, are contained within a heat-effected zone, and do not extend into areas of the structure that typically bend during use.

摘要： A system and method are disclosed for collapsing medical devices, such as self-expanding, drug-eluting stents for loading into delivery catheters. The collapsing apparatus may be used for crimping expandable stents and other devices onto a balloon catheter. The medical device is cooled below the austenitic phase transformation temperature of the material forming the device, such as stainless steel or nitinol, and may be cooled until the material has fully transformed to the martenstitic state. For coated medical devices, the device is warmed to a temperature just below the beginning of austenite phase transformation prior to collapsing. An apparatus having a plurality of offset blades, linear bearings, radial bearings and an actuator mechanism is provided for collapsing the medical device. The system is configured with a mandrel subassembly to push the medical device into a catheter sheath, and with a nozzle subassembly to direct cold gas to the medical device.

摘要： A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to be pre-formed for expansion thereof so as to seal off the inner surface of a blood vessel, to inhibit the forming of a gap therein, for inhibiting embolic material from passing therethrough, and to be foreshortened to enable insertion thereof through confined spaces. The system, in another embodiment thereof, enables expandable material to be formed into an expandable configuration of an embolic protection device for capturing embolic material, which is capable of sealing off the inner surface of the blood vessel.

摘要： An expandable cage used in conjunction with an embolic filtering device has a strut configuration including a proximal strut assembly coupled to a distal strut assembly. A filter can be attached to the distal strut assembly which has an inlet opening. The proximal strut assembly is “offset” from the distal strut assembly in that these proximal struts extend substantially along the vessel wall of the patient, rather than being “centered” in the body vessel when the cage is expanded in a body vessel. As a result, there is little cage structure directly in front of the opening of the filter, resulting in a virtually unobstructed opening for the filter.

摘要： Cold worked nickel-titanium alloys that have linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite as applied to a medical device having a strut formed body deployed from a sheath is disclosed. In one application, an embolic protection device that employs a linear pseudoelastic nitinol self-expanding strut assembly with a small profile delivery system for use with interventional procedures is disclosed. Linear pseudoelastic nitinol is used in the medical device as distinct from non-linear pseudoelastic (i.e., superelastic) nitinol. The expandable strut assembly is made from a small diameter tubing of cold worked nickel-titanium alloys. The self-expanding struts that deploy the filter element is laser cut from a large diameter cold worked nickel-titanium alloy, then joined to the small diameter tubing.

摘要： A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a dryer having a telescoping plenum which provides a drying chamber for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The drying chamber improves efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provides a platform that can effectively support stents that are over 40 mm in length.

摘要： An apparatus and method for applying a coating composition to a stent. A mandrel for supporting the stent has one or more drive pins and other supporting structure that loosely supports the stent, in an unstable position. The support permits freedom of movement of the stent relative to the mandrel to cause the stent to frequently re-position itself over the mandrel during a spraying process. When a coating composition is applied, the stent randomly or periodically moves about relative to the mandrel due to intermittent contact between the stent and the rotating mandrel and fluidic forces applied through the sprayed coating composition.
