Surface sealing for implants

An implant for insertion in a body lumen, the implant comprising:

• a surface, at least a portion of the surface being arranged to contact a wall of the body lumen and/or bodily fluid flowing therethrough when the implant is inserted in the body lumen at a target location, wherein the at least a portion of the surface is a plain surface provided with assigned target characteristics comprising at least hydrophilicity,
• wherein the at least a portion of the surface and thus the plain surface is made of a metal or of a metal alloy, or of a ceramic material, or of a combination thereof,
• wherein the at least a portion of the surface is covered with a gas-tight surface sealing which adheres directly to the plain surface and is configured to dissolve during insertion of the implant in the body lumen, such that the surface sealing has been dissolved and at least a hydrophilic portion of the plain surface is exposed to the body lumen prior to the target location being reached,
• wherein the surface sealing consists of a soluble carbohydrate being a monosaccharide or a sugar alcohol, or being a disaccharide, or a combination thereof, and
• wherein a thickness of the surface sealing is in a range of up to a few hundred micrometers and is thinner than a structure of the implant it coats, the surface sealing configured to provide elasticity that supports flexibility and deformability of the implant capable of preserving the assigned target characteristics of the at least a portion of the surface.
