Abstract
The tendon and/or ligament substitute is inelastic in the longitudinal direction and is formed of a round rope having a core filament and outer filaments of smaller diameter surrounding the core filament. Each filament is encased in a tube to reduce abrasion and a cover holds the various filaments together. The construction of the filaments insures an increase in elasticity from the inside to the outside as required for biological-medical reasons.
Claims12
A biologically implantable member for tendons and ligaments comprising
- at least one rope having a core filament;
- a first tube encasing said filament therein in relatively longitudinally movable relation;
- at least one ring of outer filaments surrounding said first tube and said core filament, each said outer filament being of smaller diameter than said core filament;
- a plurality of tubes, each said tube encasing a respective outer filament therein in relatively longitudinally movable relation;
- and a cover encircling said ring whereby said rope has an outwardly increasing bending elasticity from said core filament.
