Accounting Policies (Policies) [Abstract]  
ASC Topic 820, Fair Value Measurements and Disclosures
We determine the fair value of our derivative instruments using the framework prescribed by ASC Topic 820, Fair Value Measurements and Disclosures, by considering the estimated amount we would receive or pay to transfer these instruments at the reporting date and by taking into account current interest rates, foreign currency exchange rates, the creditworthiness of the counterparty for assets, and our creditworthiness for liabilities. In certain instances, we may utilize financial models to measure fair value. Generally, we use inputs that include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; other observable inputs for the asset or liability; and inputs derived principally from, or corroborated by, observable market data by correlation or other means.
ASC Update No. 2011-04
In May 2011, the FASB issued ASC Update No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. Update No. 2011-04 clarifies the FASB's intent about the application of certain existing fair value measurement and disclosure requirements and changes certain principles or requirements for measuring or disclosing information about fair value. It requires, for all Level 3 fair value measurements, new quantitative information about significant unobservable inputs used. We adopted Update No. 2011-04 beginning in our first quarter ended March 31, 2012. The adoption of Update No. 2011-04 did not impact our results of operations or financial position. See Note B - Acquisitions and Note D - Goodwill and Other Intangible Assets for relevant disclosures.
ASC Topic 815, Derivatives and Hedging
Financial Instruments
We recognize all derivative financial instruments in our consolidated financial statements at fair value in accordance with ASC Topic 815, Derivatives and Hedging, and we present assets and liabilities associated with our derivative financial instruments on a gross basis in our financial statements. In accordance with Topic 815, for those derivative instruments that are designated and qualify as hedging instruments, the hedging instrument must be designated, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. The accounting for changes in the fair value (i.e. gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. Our derivative instruments do not subject our earnings or cash flows to material risk, as gains and losses on these derivatives generally offset losses and gains on the item being hedged. We do not enter into derivative transactions for speculative purposes and we do not have any non-derivative instruments that are designated as hedging instruments pursuant to Topic 815. Refer to Note E – Fair Value Measurements for more information on our derivative instruments.

Comprehensive Income Disclosure [Text Block]
ASC Update No. 2011-05
In May 2011, the FASB issued ASC Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. Update No. 2011-05 requires that net income, items of other comprehensive income and total comprehensive income be presented in one continuous statement or two separate consecutive statements. The amendments in this update also require that reclassifications from other comprehensive income to net income be presented on the face of the financial statements. We adopted Update No. 2011-05 beginning in our first quarter ended March 31, 2012. Update No. 2011-05 is related to presentation only and its adoption did not impact our results of operations or financial position. See our Consolidated Statements of Comprehensive Income for relevant presentation for additional information.
Subsequent Events, Policy [Policy Text Block]
Subsequent Events
We evaluate events occurring after the date of our accompanying consolidated balance sheets for potential recognition or disclosure in our financial statements. We did not identify any material subsequent events requiring adjustment to our accompanying consolidated financial statements (recognized subsequent events). Those items requiring disclosure (unrecognized subsequent events) in the financial statements have been disclosed accordingly. Refer to Note K– Commitments and Contingencies, Note L - Stockholders' Equity and Note H - Restructuring-Related Activities for more information.
Goodwill and Intangible Assets, Policy [Policy Text Block]
ASC Update No. 2012-02
In July 2012, the FASB issued ASC Update No. 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. Update No. 2012-02 provides companies with the option to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If the company concludes that it is more likely than not that the asset is impaired, it is required to determine the fair value of the intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying value in accordance with Topic 350. If the company concludes otherwise, no further quantitative assessment is required. We adopted Update No. 2012-02 beginning in our third quarter ended September 30, 2012. The adoption of Update No. 2012-02 did not impact our results of operations or financial position. See Note B - Acquisitions and Note D - Goodwill and Other Intangible Assets for relevant disclosures.
Cash and Cash Equivalents, Policy [Policy Text Block]
Cash and Cash Equivalents
We record cash and cash equivalents in our consolidated balance sheets at cost, which approximates fair value. Our policy is to invest excess cash in short-term marketable securities earning a market rate of interest without assuming undue risk to principal, and we limit our direct exposure to securities in any one industry or issuer. We consider all highly liquid investments purchased with a remaining maturity of three months or less at the time of acquisition to be cash equivalents.
We record available-for-sale investments at fair value and exclude unrealized gains and temporary losses on available-for-sale securities from earnings, reporting such gains and losses, net of tax, as a separate component of stockholders’ equity, until realized. We compute realized gains and losses on sales of available-for-sale securities based on the average cost method, adjusted for any other-than-temporary declines in fair value. We held no available-for-sale securities during 2012, 2011 and 2010.
Concentration Risk Disclosure [Text Block]
Concentrations of Credit Risk
Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, derivative financial instrument contracts and accounts and notes receivable. Our investment policy limits exposure to concentrations of credit risk and changes in market conditions. Counterparties to financial instruments expose us to credit-related losses in the event of nonperformance. We transact our financial instruments with a diversified group of major financial institutions with investment grade credit ratings and actively monitor their credit ratings and our outstanding positions to limit our credit exposure. We provide credit, in the normal course of business, to hospitals, healthcare agencies, clinics, doctors' offices and other private and governmental institutions and generally do not require collateral. We record our accounts receivable in our consolidated balance sheets at net realizable value. We perform on-going credit evaluations of our customers and maintain allowances for potential credit losses, based on historical information and management's best estimates. Amounts determined to be uncollectible are written off against this reserve. We recorded write-offs of uncollectible accounts receivable of $7 million in 2012, $13 million in 2011, and $15 million in 2010. We are not dependent on any single institution and no single customer accounted for more than ten percent of our net sales in 2012, 2011, or 2010 or accounts receivable at December 31, 2012 or 2011; however, large group purchasing organizations, hospital networks and other buying groups have become increasingly important to our business and represent a substantial portion of our U.S. net sales.
We closely monitor outstanding receivables for potential collection risks, including those that may arise from economic conditions, in both the U.S. and international economies. Our European sales to government-owned or supported customers in Southern Europe, specifically Greece, Italy, Spain and Portugal are subject to an increased number of days outstanding above historical levels prior to payment due to the fiscal and debt crises in these countries. Historically, receivable balances with certain publicly-owned hospitals in these countries accumulate over a period of time and are then subsequently settled as large lump sum payments. While we believe our allowance for doubtful accounts in these countries is adequate as of December 31, 2012, if significant changes were to occur in the payment practices of these European governments or if government funding becomes unavailable, we may not be able to collect on receivables due to us from these customers and our write-offs of uncollectible amounts may increase. As of December 31, 2012, our net receivables in these countries greater than 180 days past due totaled $51 million, of which $17 million were past due greater than 365 days.
