Patent attorneys are often grasping for words to describe openings, and a word to describe some with one or more openings is fenestrated (see U.S. Patent No. 8,506.984).
U.S. Patent No. 8,506,904, shows a fenestrated portion of a device having a plurality of openings.
Fenestrated appears in more than 1318 U.S. Patents.
