The present invention relates to a method and a device for alleviating and/or preventing conditions relating to damaged joints involving articulating surfaces. In a first aspect the present invention relates to a prosthetic device for insertion into a joint cavity of a joint of a vertebrate, such as a human, said device consisting of a biocompatible material comprising at least a first polymeric component and a second polymeric component, wherein the chain length of the first polymeric component is longer than the chain length of the second polymeric component, the polymeric components in particular being polyethylene, polypropylene and/or polyvinylpyrrolidone. A further aspect of invention relates to a method for introducing the prosthetic device into a joint, such as a method comprising locking the device to an intro-articular component, thereby fixing or retaining the device in the joint cavity in a manner which is substantially non-invasive with respect to cartilage and bone natively present in the joint cavity. Also the invention relates to an instrument for inserting a prosthetic device according to the invention, comprising means for deforming the prosthetic device into a reduced volume or a slender shape and means for grasping the intra-articular component to which the device is capable of interlocking.
A prosthetic device for insertion into a joint cavity of a joint of a vertebrate, said device consisting of a biocompatible material comprising at least a first polymeric component and a second polymeric component, wherein the chain length of the first polymeric component is longer than the chain length of the second polymeric component, said first and second polymeric components are not polytetrafluoroethylene or polyurethane, and wherein said first polymeric component has a carbon-backbone and the first polymeric component and the second polymeric component are compounded to form a bidispergent system.
A prosthetic device for insertion into a joint cavity of a joint of a vertebrate, said device consisting of a biocompatible material comprising at least a first polymeric component, a second polymeric component, and a third polymeric component, wherein the chain length of the first polymeric component is longer than the chain length of the second polymeric component, said first and second polymeric components are not polytetrafluoroethylene or polyurethane, and said third polymeric component being different from the first and/or the second polymeric component.
A prosthetic device for insertion into a joint cavity of a joint of a vertebrate, said device having a body with a surface and a hole, and said device consisting of a biocompatible material comprising at least a first polymeric component and a second polymeric component, wherein the chain length of the first polymeric component is longer than the chain length of the second polymeric component, said first and second polymeric components are not polytetrafluoroethylene or polyurethane, and wherein the device further comprises a slit in the body of the device extending through the body of the device from the surface of the body to the hole.
A prosthetic device for insertion into a joint cavity of a joint of a vertebrate, said device consisting of a biocompatible material comprising at least a first polymeric component and a second polymeric component, wherein the chain length of the first polymeric component is longer than the chain length of the second polymeric component, said first and second polymeric components are not polytetrafluoroethylene or polyurethane, and said device is capable of locking itself to an intra-articular component by at least one element of the device surrounding the intra-articular component in such a manner that displacement of the element is limited by interlocking with said component.
