Abstract

A solid lubricant for use in a medical device for lubrication of a synovial joint, wherein said lubricant comprises at least one of: a high-molecular weight hyaluronic acid; a crosslinked high-molecular weight hyaluronic acid; and a hyaluronic acid of at least two different high-molecular weights being crosslinked to form a semisolid gel.

Claims (7)

1. A method for lubricating a synovial joint in a patient, the method comprising feeding a solid lubricant into a joint cavity of the synovial joint of the patient,

wherein the solid lubricant comprises hyaluronic acid, and

controlling the feeding of the solid lubricant in response to one of a pre-programmed time-schedule or to a sensor sensing a physical parameter of the patient.

2. The method according to claim 1 , wherein the hyaluronic acid is a high-molecular weight hyaluronic acid.

3. The method according to claim 2 , wherein the high-molecular weight hyaluronic acid has a molecular weight in the range of 4-6 MDa.

4. The method according to claim 1 , wherein the solid lubricant comprises a hydrophilic polymer comprising a natural polysaccharide.

5. The method according to claim 4 , wherein the solid lubricant comprises a hydrophilic polymer comprising a protein.
