Abstract
An intraluminal, balloon expandable stent for implantation in a body lumen is disclosed. The present invention provides a lumen support stent with an unobstructed through-lumen for use in a blood vessel. A constraining mechanism is provided for securely maintaining the stent in the collapsed condition during delivery. The stent is preferably formed with a series of interconnected slide and lock mechanisms for permitting movement from a collapsed condition to an expanded condition and inhibiting radial recoil from the expanded condition. The stent may be formed from a shape memory alloy for providing crush-recovery after deployment.
