Abstract: A medical device that is designed to be introduced into a vascular system of a body.

Abstract: The present invention provides a number of compositions, including non-alcoholic and non-fermented aqueous solutions comprising trans-resveratrol and/or other polyphenols. In one aspect, the present invention provides retail or commercially available beverages comprising trans-resveratrol and/or other polyphenols.

Abstract: A removable, low profile, vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood, comprising a guidewire having proximal and distal markers, a filter delivery and deployment system, having an outer member and an inner member, and a filter removably attached near the distal end of the inner member. The filter comprises proximal and distal basket sleeves which position the filter between the proximal and distal markers on the guidewire, after the guidewire is in position past the vessel occlusion. The guidewire placement prior to filter delivery may facilitate access to the interventional site, especially through tortuous anatomy. Also, retrievability of the filter from the wire may avoid loss of guidewire position, which may occur following removal of filters permanently attached to guidewires.

Abstract: A removable vascular filter device for blocking micro-and macro-emboli while allowing continued perfusion of blood, comprises a guidewire having distal and proximal portions, wherein there is a recess in the distal portion and a filter comprising a flexible filter membrane and a filter membrane support structure. The filter membrane has a fixed inner portion and a free outer portion, wherein the filter membrane fixed inner portion is movably attached toward the distal end of the guidewire recess and wherein the filter membrane free outer portion is positioned in the recess when the filter membrane is in a collapsed state. A deploying means causes the filter membrane proximal end portion to assume a position substantially normal to the longitudinal axis of the guidewire.

Abstract: A non-sheath balloon expandable stent delivery system (20) has a catheter-mounted balloon (25) whose ends (26, 27) are invaginated and folded over onto the balloon itself. Thus, when a stent (29) is mounted on the balloon, the balloon ends fold over the ends of the stent, thus covering its ends and serving a sheath function. The folded over ends (26A, 27A) could cover the terminal portions of the stent or could reach to the middle of the stent and cover the entire stent. When the balloon is inflated to deploy the stent; the balloon ends inflate and uncover the stent. The balloon inflation ports in the balloon catheter could be positioned so as to preferentially direct the inflating fluid into the balloon ends/invaginations (26A, 27A) to assure their inflation before the inflation of the body of the balloon.

Abstract: A removable vascular filter system for blocking micro- and macro-emboli while allowing the continued perfusion of blood comprises a filter membrane positioned on a guidewire, wherein a free end of the membrane sits tightly against the guidewire when the filter membrane is in a collapsed state and wherein the filter has a means for deploying the filter membrane to assume a position substantially normal to the longitudinal axis of the guidewire. The filter membrane is comprised of a fine mesh material which has a pore size capable of blocking emboli while allowing continued blood flow, a preferred embodiment of which comprises regularly spaced, laser-formed holes.

Abstract: A stent for use in the treatment of stenosis of the ostium of tubular organs, more particularly, blood vessels comprising a multiplicity of flanges located at an end of a generally tubular stent body. The flanges permit the accurate positioning of the stent within the vessel, while presenting dislodgement of the stent.

Abstract: An expandable intraluminal stent able to resist axial compression, comprising a body portion having a generally cylindrical structure formed by a series of interconnected bars or struts, at least one of said struts being formed of two portions having overlapping free ends; and a plurality of teeth projecting on adjacent surfaces of said overlapping free ends; whereby said stent is expanded to allow said two portions of said at least one strut to overlap at said free ends, whereby said teeth on said adjacent surfaces of said overlapping free ends of said struts engage one another to retain said stent in its expanded shape.
