    摘要： A direct stick tear-away introducer having an elongate intraluminal medical device, comprising a proximal and a distal end. A sheath is disposed about the medical device and extends from the distal end of the medical device. A blade is bonded to a distal end of the sheath, and a weakened region on the sheath extends longitudinally from the distal end to a proximal end of the sheath. The introducer has the ability to incise a body tissue and allow insertion of a medical device housed within the introducer into the body tissue. Methods for using the devices herein are also disclosed.

    摘要： A probe having the ability to deliver cardioplegia solution to the coronary sinus under direct visualization and to provide venous drainage from the right atrium for cardiopulmonary bypass. The probe has an elongate tubular member, including a distal end, a proximal end, and a lumen. A membrane, optionally perforated, mounted within the lumen of the tubular member partitions the lumen and is removable or penetrable by a cardioplegia catheter. The distal end comprises a toroidal balloon or a circumferential recessed vacuum manifold. A vacuum port communicates with the distal end of the tubular member or the vacuum manifold. Methods of using the cardioplegia access view probe for catheterization of the coronary sinus and for venous return as herein described are also disclosed.

    摘要： Exemplary occlusion and molding devices and methods involve the use of an expandable balloon. Methods of sealing an aortic side branch in a patient can include advancing an occlusion device within the aorta, positioning a toroidal balloon of the occlusion device adjacent to the aortic side branch, and inflating the balloon to prevent peripheral blood flow from the aorta into the aortic side branch while a central aperture of the balloon allows descending aortic blood flow therethrough. Methods of molding a stent against an interior surface of a vessel of a patient can include advancing a molding device within the vessel, positioning a toroidal balloon of the molding device at least partially withing the stent, and inflating the balloon to exert force to the stent thus dilating the stent and molding it to the interior of the vessel while a central aperture of the balloon allows blood flow therethrough.

    摘要： A filter device for temporary placement of a filter in an artery or vein is disclosed. The device includes an expandable filter mounted on a distal end of a catheter. The filter comprises a plurality of circumferentially adjacent porous segments that are arranged generally about the surface of a cone having an open base, and the segments are engaged to one another by means, such as a hook. The filter conforms to the interior of a vessel wall when expanded and contracts to a consistent diameter without bunching when stowed. Methods of using the filter device to entrap and remove embolic material from a vessel during endovascular procedures are also disclosed.
