Throughout the integration, our goal is for a smooth transition that creates as little disruption as possible to ATS Medical employees.
2.	Who is Medtronic? What is the Medtronic Mission? Where is Medtronic headquartered? How many people does Medtronic employ?	Founded in 1949, Medtronic is the world’s leading medical technology company, with global headquarters in Minneapolis, Minnesota. The company employs approximately 38,000 people worldwide. Its international headquarters is in Singapore. Medtronic has more than 270 locations and conducts business in more than 120 countries.
		Medtronic’s Mission is: To contribute to human welfare by the application of biomedical engineering in the research, design, manufacture and sale of instruments or appliances that alleviate pain, restore health and extend life.
		Medtronic’s CardioVascular business serves the medical specialties of interventional cardiology, cardiac surgery, vascular surgery and interventional radiology with a broad range of innovative products and services.

INVESTMENT COMMUNITY / MEDIA QUESTIONS
3.	What is the financial impact to Medtronic?	The transaction will be 2 cents dilutive to Medtronic’s FY11 earnings and neutral to FY12 earnings. On an operating basis (that is, excluding integration costs), we expect the transaction to be earnings neutral in FY11.
		The total revenue was $75.7M for the year 2009.
4.	What is the current market? What is the potential market?	We believe that current surgical valve demand is $1.2B, with two-thirds being tissue and one-third mechanical. Surgical valve demand is growing in the low- to mid-single digits. We believe that there is opportunity to grow the mechanical segment more quickly in some international geographies.
5.	Which physicians do we expect to implant / use these products?	Cardiac Surgeons

6.	What is ATS Medical’s revenue?	The total revenue was $75.7M for the year 2009. ATS Medical 2008-2009 Revenue by Product (000s)

Talking Points

Talking Points
ATS Medical Inc Signing Communications

Audience: To be used for both internal and external audiences.

Medtronic has signed an agreement to acquire ATS Medical, Inc.

• The closing of the acquisition is expected this summer or fall, pending approval by ATS Medical shareholders and receipt of regulatory clearances in various jurisdictions.

• ATS Medical has developed leading technologies in the field of surgical heart valves and cryoablation. They are known for their high standards of quality in these fields.

• The company’s innovative Open Pivot^® bileaflet mechanical valve and 3f^® pericardial valve technology, along with its CryoMaze^® family of ablation products, will extend Medtronic’s current product offerings to cardiac surgeons.

• ATS Medical’s CE-marked sutureless surgical ATS 3f Enable^® Aortic Bioprosthesis System is currently available in Europe and other select centers outside the United States.

• Prior to completion of the acquisition, ATS and Medtronic will, as is required by law, continue to operate their businesses completely separately with all management decisions being made by their respective management teams. ATS must continue to operate independently, without any influence by Medtronic.

• The acquisition of ATS Medical allows Medtronic to re-enter the mechanical valve segment with leading technology, particularly outside of the U.S. and in geographies where mechanical valves are the standard of care.

• We now will have a broader range of surgical valves and tissue ablation technologies for surgeons as they seek to address individual patient needs.
