<p>A strut assembly (14) to be used in conjunction with an embolic filtering device (10) has varying strut (30) thicknesses, with the thickness selected based at least in part on the flexing characteristics of the particular portion of the strut assembly (14). The strut assembly (14) is formed with patterns having flexing portions (36) and stable portions (38), with the flexing portions (36) contributing to the flexibility of the strut assembly (14) during delivery and recovery in the patient's vasculature. The stable portions (38) remain relatively unflexed and stiff when being delivered or recovered from the patient's vasculature. The stable portions (38) provide strength and increased radiopacity to the strut assembly which is needed when the strut assembly (14) is deployed in the body vessel. The flexing portions (36) act much like a mechanical hinges in providing the needed flexibility to resiliently bend when being delivered through tortuous anatomy of the patient.</p> |
