Patent number: 11419711Abstract: Bio-adhesive textured surfaces are described which allow implants to be localized within a living body. Hierarchical levels of texture on an implantable medical device, some capable of establishing a Wenzel state and others a Cassie state, may be employed to interface with living structures to provide resistance to device migration. Since a gaseous state is traditionally required to establish a Cassie or Wenzel state, and gases do not remain long in living tissue, described herein are tissue/device interactions analogous to the above states with the component normally represented by a gas replaced by a bodily constituent, wherein separation of tissue constituents develops and an analogous Cassie, Wenzel, or Cassie-Wenzel state evolves. Further methods of making molds to produce said devices are described herein.Type: GrantFiled: July 29, 2021Date of Patent: August 23, 2022Assignee: BVW Holding AGInventors: Lukas Bluecher, Michael Milbocker
