| Segment And Geographic Information     | SEGMENT AND GEOGRAPHIC INFORMATIONSegment InformationOn August 30, 2012, the Company announced the realignment of its product divisions into two new business units (or divisions): the Implantable Electronic Systems Division (combining its legacy Cardiac Rhythm Management and Neuromodulation product divisions) and the Cardiovascular and Ablation Technologies Division (combining its legacy Cardiovascular and Atrial Fibrillation product divisions). In addition, the Company centralized certain support functions, including information technology, human resources, legal, business development and certain marketing functions. The organizational changes were part of a comprehensive plan to accelerate our growth, reduce costs, leverage economies of scale and increase investment in product development. The Company began reporting under the new organizational structure as of the beginning of fiscal year 2013. Prior period amounts in the tables below have been recast to conform to the Company's new reportable segment structure.The Company's principal products in each business unit are as follows: Implantable Electronic Systems Division (IESD) – tachycardia implantable cardioverter defibrillator systems (ICDs), bradycardia pacemaker systems (pacemakers) and neurostimulation products (spinal cord and deep brain stimulation devices); and Cardiovascular and Ablation Technologies Division (CATD) – vascular products (vascular closure products, pressure measurement guidewires, optical coherence tomography (OCT) imaging products, vascular plugs and other vascular accessories), structural heart products (heart valve replacement and repair products and structural heart defect devices) and atrial fibrillation (AF) products (electrophysiology (EP) introducers and catheters, advanced cardiac mapping, navigation and recording systems and ablation systems).IESD and CATD are considered the Company's reportable segments. Net sales of the Company’s reportable segments include end-customer revenues from the sale of products they each develop and manufacture or distribute. The costs included in each of the reportable segments’ operating results include the direct costs of the products sold to customers and operating expenses managed by each of the reportable segments. Certain expenses managed by the Company’s selling and corporate functions, including all stock-based compensation expense, impairment charges, certain acquisition-related charges, IPR&D charges, excise tax expense, special charges and centralized support groups' operating expenses are not recorded in the IESD and CATD reportable segments. As a result, reportable segment operating profit is not representative of the operating profit of the products in these reportable segments. Additionally, certain assets are managed by the Company’s selling and corporate functions, principally including trade receivables, inventory, cash and cash equivalents, certain marketable securities and certain deferred income taxes. For management reporting purposes, the Company does not compile capital expenditures by reportable segment; therefore, this information has not been presented, as it is impracticable to do so.The following table presents net sales and operating profit by reportable segment (in millions): IESD CATD Other TotalThree Months ended June 29, 2013:       Net sales$826 $577 $— $1,403Operating profit565 341 (624) 282Three Months ended June 30, 2012:       Net sales$852 $558 $— $1,410Operating profit591 331 (584) 338        Six Months ended June 29, 2013:       Net sales$1,603 $1,138 $— $2,741Operating profit1,096 674 (1,180) 590Six Months ended June 30, 2012:       Net sales$1,690 $1,115 $— $2,805Operating profit1,173 661 (1,194) 640The following table presents the Company’s total assets by reportable segment (in millions):Total AssetsJune 29, 2013 December 29, 2012IESD$2,598 $2,320CATD2,960 2,967Other4,102 3,984 $9,660 $9,271Geographic InformationThe following table presents net sales by geographic location of the customer (in millions): Three Months Ended Six Months EndedNet SalesJune 29, 2013 June 30, 2012 June 29, 2013 June 30, 2012United States$669 $664 $1,309 $1,329International       Europe376 374 733 748Japan137 163 276 328Asia Pacific125 116 237 221Other96 93 186 179 734 746 1,432 1,476 $1,403 $1,410 $2,741 $2,805The amounts for long-lived assets by significant geographic market include net property, plant and equipment by physical location of the asset as follows (in millions):Long-Lived AssetsJune 29, 2013 December 29, 2012United States$1,055 $1,036International   Europe75 82Japan34 32Asia Pacific78 82Other190 193 377 389 $1,432 $1,425 |
