Frank J. Callaghan retired as president of the Cardiovascular and Ablation Technologies Division at St. Jude Medical as the company initiated organizational changes.

The St. Paul, Minn.-based company announced that Callaghan stepped down and several other executives assumed new duties with the integration of two operating divisions into one research and development unit at the end of January.

Eric S. Fain, MD, formerly president of the Implantable Electronic Systems Division, became group president of St. Jude Medical. Fain will be responsible for integrating the Implantable Electronic Systems and the Cardiovascular and Ablation Technologies divisions into a single R&D organization. He also will oversee company-wide clinical, regulatory and R&D activities.

Michael Rousseau, formerly group president, is now chief operating officer and will oversee global sales, marketing, quality, technology development, operations and supply chain. Other changes included Scott Thome assuming the newly created position of vice president, global operations and supply chain; Lisa Andrade, chief marketing officer; and Jeff Dallager, vice president, corporate controller.

Callaghan joined St. Jude Medical in 2005 as part of the acquisition of Endocardial Solutions, which specialized in diagnostic and therapeutic catheters used in atrial fibrillation ablation and other electrophysiology catheterization procedures. Callaghan will continue to serve as an adviser through 2014.
