A device to be used as a vascular stent comprising a cylindrical open-ended wire component made of a low memory metal such as copper alloy, titanium, or gold, providing a radial support from within a blood vessel after implantation therein. The coronary stent is characterized by its ability to be expanded radially to a larger diameter after initial implantation and means for causing said stent to expand to a larger diameter and a method for transporting, positioning and implantation of such coronary stent transluminally to have said stent act as a permanent prosthesis to assure vascular patency. And method for simultaneous angipolasty and stent implant procedure.
A radially expandable stent for implantation within a body vessel, comprising a wire winding in a hollow cylindrical shape, the winding including a series of groups of helical coils along the length of the winding for providing radial strength, the coils of each group being wound in a direction oppo
A radially expandable stent for implantation within a body vessel, comprising a wire winding in a hollow cylindrical shape, the winding including a series of groups of helical coils along the length of the winding for providing radial strength, the coils of each group being wound in a direction opposite to the direction of winding of the next adjacent group of coils, a reversely-turned loop joining each two successive groups of coils for allowing smooth expansion of the adjacent groups of coils, and means within the wire winding for expanding the winding.
