Abstract
A semi-bioabsorbable connective tissue prosthesis, e.g., a replacement for the human anterior cruciate ligament, is provided whose stress-strain characteristics closely match those of the natural tissue.
Claims58
A connective tissue prosthesis comprising:
- a) a core made up of a first biocompatible composite yarn extending in a lengthwise direction;
- and
- b) a sheath surrounding the core, said sheath being fabricated from a second biocompatible yarn;
- the first composite yarn in said core (a) comprising a non-bioabsorbable core yarn component surrounded by an at least semi-bioabsorbable sheath yarn component.
1 more element
A connective tissue prosthesis comprising:
- a tubular component fabricated from composite yarn, said yarn comprising a biocompatible, core yarn component surrounded by a biocompatible, at least semi-bioabsorbable sheath yarn component.
Method for manufacturing a connective tissue prosthesis, comprising
- forming said connective tissue prosthesis from a first biocompatible composite yarn comprising a non-bioabsorbable core yarn component surrounded by an at least semibioabsorbable sheath yarn component.
Method for manufacturing a tubular connective tissue prosthesis, comprising
- forming a tubular component from composite yarn comprising a biocompatible, non-bioabsorbable core yarn component surrounded by a biocompatible, at least semi-absorbable sheath yarn component.
