  • Nerve conduits
    Patent number: 11559604
    Abstract: The invention provides bioresorbable nerve guidance conduits made from polymer blends which include polyhydroxyalkanoates (PHAs). In particular, the invention provides nerve guidance conduits having a body which comprises a polymer blend comprising: (a) from 60 to 98 wt. % of a first component which is a PHA copolymer comprising two or more different medium chain length hydroxyalkanoate monomer units; and (b) from 2 to 40 wt. % of a second component which is either a PHA homopolymer containing a short chain length hydroxyalkanoate monomer unit, or a polylactide (PLA). The invention further relates to polymer blends comprising (a) and (b).
