Baxter Healthcare Corp.: An Irvine-based subsidiary announced last week that it has bought a Brazilian manufacturer of heart valves.

Baxter’s Bentley division acquired Macchi Engenharia Biomedica Ltda., based in Sao Paulo. Macchi makes blood oxygenators and mechanical heart valves and distributes pacemakers. Financial terms of the transaction were not disclosed.

Bentley also said it has signed a new four-year agreement with Haemonetics Corp. of Braintree, Mass., to continue distributing Haemonetics’ surgical blood-salvage products in the United States. The automated systems are used to collect patients’ blood before, during and after surgery for re-infusion to the patient.

Baxter Healthcare Corp. is the main unit of Baxter International Inc. in Deerfield, Ill., the world’s leading maker of health care products. Bentley makes disposable oxygenators, which provide oxygen to the blood while the heart and lungs are stopped during open-heart surgery.
