PROBLEM TO BE SOLVED: To provide a stent for insertion into a vessel of a patient. SOLUTION: The stent comprises front and back open ends and a tubular member extending therebetween. The tubular member has a first smaller diameter for insertion into the blood vessel of a patient and navigation through the vessels, and a second larger diameter for deployment into the target area of the vessel. The tubular member is made of a plurality of adjacent hoops. The hoops include a plurality of longitudinal struts and a plurality of loops connecting adjacent struts. The stent further includes a plurality of bridges having curved parts to bridge connections which connect adjacent hoops to one another. The bridge to loop connection points are separated angularly with respect to the longitudinal axis. The bridges have one end attached to a loop, another end attached to a loop on an adjacent hoop. The bridges have a non-linear curved profile between their bridge to loop connection points. COPYRIGHT: (C)2009,JPO&INPIT |
