Abstract:
1. An implantable medical device assembly, comprising: a first preformed layer member having a surface defining a plurality of preformed first engageable features; a second preformed layer member having a surface defining a plurality of cooperating, preformed second engageable features; and an interface between the first preformed layer member and second preformed layer member in which the preformed first engageable features frictionally engage with the cooperating, preformed second engageable features to form said assembly, the preformed first engageable features and the cooperating, preformed second engageable features being formed in morphologies of dimensional magnitudes of about 10-100 nm before being frictionally engaged engaging imperfectly, without a requirement of careful alignment, and with open spaces among the preformed first and second engageable features at the interface.
