摘要:
The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.
摘要:
Annuloplasty rings reduce or eliminate tricuspid regurgitation and/or tricuspid annulus dilation. An adjustable annuloplasty device includes a ring body having a first free end and a second free end. The ring body includes a shape memory material to provide a shape change to the adjustable annuloplasty device upon activation. The ring body includes a first segment including the first free end and following a curved path corresponding to an anterior leaflet region of a tricuspid annulus, a second segment following a curved path corresponding to a posterior leaflet region of the tricuspid annulus, and a third segment including the second free end and at least partially following a linear path corresponding to a portion of a septal leaflet region of the tricuspid annulus. Activation of the shape memory material changes a dimension of the adjustable annuloplasty device.
