A stent (1) comprising a self-expandable cylindrical body constructed of a single integral piece of material (8), including a plurality of wavy closed windings (10), and strips (16) interconnecting the windings such that the stent is prevented from stretching longitudinally, is provided. A method of manufacture of the stent by winding a continuous wire (10) upon spikes (44) on an elongated mandrel (40) to form a self-expanding shape memory coil is disclosed. A method of implanting the stent by releasably securing the stent in a sheath for insertion into a body cavity to maintain patency, is also disclosed. |
