Abstract: The disclosure relates to a bone anchored hearing aid device unit including a housing and an actuator having a first plate piezo element, and a clamp system configured for attaching the first plate piezo element to the housing, characterized in that the actuator has a second plate piezo element, in that the clamp system connects the first plate piezo element and the second plate piezo element, via the housing, and in that the clamp system is adapted for transferring, via the housing, a dynamic force between the first plate piezo element and the second plate piezo element. A method of operating a bone anchored hearing device unit is also disclosed.

Abstract: According to the invention there is provided inter alia an implantable medical device with coatings comprising an immobilized heparin moiety and elutable paclitaxel and to methods for making such devices.

Abstract: There is provided inter alia a substrate with a surface having a hydrophilic coating comprising a cross-linked copolymer of components A and B, and optional components C and D; wherein component A comprises one or more C2-C16 hydrophilic monomers each bearing one or more alkene and/or alkyne groups; component B comprises one or more hydrophilic polymers each bearing two or more alkene and/or alkyne groups; component C, if present, comprises one or more beneficial agents each bearing one or more alkene or alkyne groups; and component D, if present, comprises one or more low molecular weight cross-linking agents each bearing two or more functional groups independently selected from thiol, alkene and alkyne groups; wherein the cross-linked copolymer is formed by radical polymerization involving the alkene and/or alkyne groups of components A, B and C (if present) and involving the functional groups of component D (if present); wherein the hydrophilic coating optionally comprises component E which comprises one
