Patent number: 7747946Abstract: Adornments are applied to shapes in a diagram that graphically displays data about those shapes. Once the adornments are applied to a shape, the information displayed is automatically updated as the underlying shape data changes. The appearance of the diagram is updated automatically when the user updates the data for their shapes. The set of adornments that may be applied to shapes is extensible. A mechanism and interface is defined for creating additional adornments that have customized looks or behaviors.Type: GrantFiled: April 11, 2005Date of Patent: June 29, 2010Assignee: Microsoft CorporationInventors: Mark T. Nelson, Cathy L. McBride, Michael J. Woolf, Patrick Leahy

Patent number: 6053390Abstract: A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod. The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod. An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site. The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.Type: GrantFiled: May 10, 1999Date of Patent: April 25, 2000Assignee: United States SurgicalInventors: David T. Green, Henry Bolanos, Henry R. Sienkiewicz, Patrick Leahy
