  • Publication number: 20130245206
    Abstract: The bioabsorbable polymers and compositions of the present invention may be formed into medical devices such as stents that can be crimped onto a catheter system for delivery into a blood vessel. The properties of the bioabsorbable polymers allow for both crimping and expansion of the stent. The crystal properties of the bioabsorbable polymers may change during crimping and/or expansion allowing for improved mechanical properties such as tensile strength and slower degradation kinetics. Typically, bioabsorbable polymers comprise aliphatic polyesters based on lactide backbone such as poly L-lactide, poly D-lactide, poly D,L-lactide, mesolactide, glycolides, lactones, as homopolymers or copolymers, as well as formed in copolymer moieties with co-monomers such as, trimethylene carbonate (TMC) or ?-caprolactone (ECL).

  • Patent number: 8006700
    Abstract: A medical fastener (18), preferably bioabsorbable, is used for repairing torn soft tissue, particularly meniscal tissue (16). The fastener (18) can have an enlarged head (22) at the proximate end to engage meniscal tissue (16) adjacent to a tear (14), and a pointed distal tip (21) at the other end to ease insertion of the fastener (18) into the meniscus (16). The shank (20) of the fastener (18) bridges across the tear (14). Opposite ends of the shank (20) are secured in the meniscal tissue (16) by a medical adhesive, preferably bioabsorbable, and preferably at locations remote from the tear (14) so as not to interfere with healing of the tear (14). The fastener (18) can have a blind bore (24) opening through the head (22) of the fastener (18) and extending through the shank (20) to a location close to the tip (21) and generally radial holes (26) communicating between the bore (24) and the exterior of the shank (20).
