The new LEADTOOLS v19 Medical Viewer control no longer uses the old Leadtools.Annotations.dll, because it is deprecated.
It is now uses Leadtools.Annotations.Core instead with the other new annotations DLLs (Leadtools.Annotations.Core.dll, Leadtools.Annotations.Automation.dll, Leadtools.Annotations.Designers.dll, Leadtools.Annotations.WinForms.dll, etc.).

About the casting problem in your code, you need to change the code as follows:
+----------------------+
void cell_DesignerCreated(object sender, MedicalViewerDesignerCreatedEventArgs e)
{
if (e.Type == MedicalViewerDesignerType.DrawDesigner)
{
Leadtools.Annotations.Designers.AnnDrawDesigner designer = (Leadtools.Annotations.Designers.AnnDrawDesigner)e.Designer;
designer.Draw += designer_Draw;
}
else if (e.Type == MedicalViewerDesignerType.EditDesigner)
{
Leadtools.Annotations.Designers.AnnEditDesigner designer = (Leadtools.Annotations.Designers.AnnEditDesigner)e.Designer;
designer.Edit += designer_Edit;
}
}
+----------------------+

Thanks,
