Medical devices and methods of making the same
First Claim
1. An endoprosthesis, comprising a tubular member defined by a plurality of bands and a plurality of connectors that extend between and connect adjacent bands, the tubular member being configured to allow for the bands to be expanded from an initial diameter to a larger diameter during use to maintain the patency of a vessel, wherein a plurality of the bands have a first median grain size and at least one of the connectors has a second median grain size less than the first median grain size.
