Method for lubricating an artificial contacting surface

A method of implanting a medical device in a human patient, wherein the medical device comprises an artificial contacting surface for a joint and at least one inlet configured to receive a lubricating fluid from a reservoir,

• said method comprising the steps of:
• a. creating an opening reaching from outside of the human body into the joint,
• b. providing said artificial contacting surface to said joint,
• c. fixating the artificial contacting surface to the joint,
• d. implanting said reservoir in the human body, and
• e. lubricating said artificial contacting surface with use of a lubricating fluid contained in said reservoir.

A method of lubricating an implantable medical device, said medical device comprising an artificial contacting surface adapted to carry weight in a joint of a patient, said artificial contacting surface comprises at least one channel for transporting of a lubricating fluid, said method comprises the steps of:

• a. implanting said medical device in a joint of the human patient,
• b. implanting a conduit for to be connected to said medical device
• c. implanting an operation device for transporting a lubricating fluid inside said conduit
• d. implanting a reservoir adapted to hold a lubricating fluid, and
• e. at least postoperatively transporting, by said operation device, said lubricating fluid from said reservoir to said artificial contacting surface in said conduit and further through said channel in said artificial contacting surface, thereby applying said lubricating fluid to said artificial contacting surface.
