  • Publication number: 20150126615
    Abstract: Compositions of P4HB with high purity have been developed. The compositions are prepared by washing P4HB biomass prior to solvent extraction, and precipitating P4HB from solution. The same solvent is preferably used to wash the P4HB biomass, and as a non-solvent to precipitate the polymer from a P4HB solvent solution. The highly pure P4HB compositions are suitable for preparing implants. The implants may be used for the repair of soft and hard tissues.

  • Publication number: 20150119792
    Abstract: A system and method for delivering a payload to ocular tissue includes a solution of light-degradable nanoparticles encapsulating the payload. The solution may be introduced to the ocular tissue by way of injection or through a contact lens into which the solution is embedded. A light source delivers a beam of light to the ocular tissue at the location where the solution was introduced to initiate breakdown of the particles, releasing the payload. The light source may be a laser, LED, LCD or arc lamp emitting in the ultraviolet light range.

  • Publication number: 20150118152
    Abstract: Compositions of P4HB (poly-4-hydroxybutyrate) and copolymers thereof, have been developed for pultrusion, as well as processes to produce profiles from these compositions by pultrusion. These pultrusion processes provide profiles without causing structural damage to the surface of the profile. The profiles may be used in medical applications. These compositions include P4HB, and copolymers thereof, having intrinsic viscosities less than 3.2 dl/g but greater than 0.8 dl/g. The profile may be formed using conditions such as: pull rate of 0.1 to 100 mm/min, die temperature of up to 95° C., rod stock temperature up to 95° C., draw ratio of up to 100×, pulling force of greater than 10 MPa, and clamping pressure at least 10% higher than the pulling force. Preferably, the profile is formed by pulling the rod stock through a series of dies placed at intervals with the hole sizes decreasing in diameter by 0.1 to 10 mm.
