Abstract
Abstract An occlusion method and apparatus. The occluder includes a elastically deformable members and a jacket. The elastically deformable members are secured in spaced relation and extend in arcuate conformation therebetween. The jacket covers at least a portion of the elastically deformable members. The elastically deformable members are configured to become compressed upon application of a force and to recover the arcuate conformation upon removal of the force to occlude a site.
