Siemens Healthineers is buying Corindus Vascular Robotics for $1.1 billion, the companies announced on Thursday, in the biggest acquisition since the Siemens subsidiary listed on the stock exchange last year.

Germany's Siemens Healthineers is buying U.S. firm Corindus, which develops robotic systems for minimally invasive vascular therapy procedures, for $4.28 per Corindus share, above the $2.42 closing price of Corindus on Wednesday.

The systems produced by Corindus, which is based in Massachusetts with approximately 100 employees, allow doctors to guide catheters and stent implants with controlling modules.

The deal is expected to close by the end of the year.
