Boston Scientific has closed its acquisition of Baylis Medical Company, a company that offers advanced transseptal access solutions as well as guidewires, sheaths and dilators used to support catheter-based left-heart procedures.

Joe Fitzgerald, executive vice president and president, cardiology, Boston Scientific, said: "The close of this acquisition allows Boston Scientific to integrate the Baylis platforms with our existing electrophysiology and structural heart offerings, further strengthening our position within the highest growth cardiology markets. We are now the only company to pair a comprehensive access portfolio with existing left-heart therapies such as left atrial appendage closure and atrial fibrillation ablation, providing physicians with a complete toolbox to treat patients with safety, efficacy and efficiency."

The transaction consists of an upfront payment of $1.75 billion and is expected to be approximately one cent accretive to adjusted earnings per share in 2022 and increasingly accretive thereafter. On a GAAP basis, the transaction is expected to be less accretive, or dilutive, in 2022 and less dilutive or increasingly accretive thereafter, due to amortisation expense and acquisition-related net charges.
