Palo Alto, Calif., Latham & Watkins partner Tracy Edmonson sees Angiotech Pharmaceuticals Inc.’s recent acquisition of American Medical Instruments Holdings Inc. as an example of the irrelevance of national borders.

Based in Vancouver, British Columbia, Angiotech develops treatments for diseases and complications associated with medical device implants, surgical interventions and acute injury or trauma. The company closed its $785 million cash acquisition of the Chicago specialty medical device manufacturer in March.
