1. A stent comprising:

  • (a) a number of equally dimensioned and shaped wires each having an essentially straight center segment with end segments bent at oblique angles with respect to said center segment such that opposite said end segments of each said wire are essentially parallel one end segment to the other; and

    (b) said wires oriented and equally spaced to form a tubular shape said bent end segments of each wire oriented parallel, over lapping and contiguous with each adjacent wire, resulting in an acute angle being formed by said center segments of each adjacent pair of wires, being secured together at all end segments; and

    (c) said wires fashioned from spring metal biocompatible material, such that said wires can be bent to store energy in said wire segments to permit reducing the diameter of said stent to permit inserting said stent into an outer catheter sized to receive said stent when compressed to permit placing said stent percutaneously within a living organism.
