Retired Johnson & Johnson CEO Ralph Larsen, 77, dies in Fla.

Under Larsen's 13-year tenure, Johnson & Johnson pioneered minimally invasive, or "keyhole" surgery, through its Ethicon Endo-Surgery unit and acquired several companies that helped grow J&J's three businesses: consumer health products, prescription drugs and medical devices and diagnostic products.

Centocor, now called Janssen Biotech, became a top maker of biologic drugs, including blockbuster immune disorder drug Remicade.
