  • POLYMERS, COMPOSITIONS AND METHOD FOR MANUFACTURING AN ARTICLE BY 3D PRINTING
    Publication number: 20230340203
    Abstract: The present invention relates to poly(amide imide) (PAI) precursor polymers which can for example be used in Vat photopolymerization processes like lithographic processes for the photofabrication of three-dimensional (3D) articles. The invention further relates to polymer compositions including these poly(amide imide) (PAI) precursor polymers. Still further, the invention relates to vat photopolymerization methods to form three-dimensional (3D) objects that incorporate the aforementioned polymer compositions.

  • Surgical tool
    Patent number: 8382791
    Abstract: Recent advances in minimally invasive surgical procedures have created a demand for smaller scale tools with improved performance characteristics. Attempts to scale down modern tools to the meso level (1-5 mm) have caused severe performance losses. Surgical tools of the present invention provide significant improvements in operable range and force application for both grasping and spreading when compared to currently used endoscopic forceps. This is achieved by using two actuators that separately control the spreading and grasping functions of the surgical tool.
