Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements of Medtronic plc and its subsidiaries (Medtronic plc, Medtronic, or the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the consolidated financial statements include all of the adjustments necessary for a fair statement in conformity with U.S. GAAP. Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the financial statements and during the reporting period. Actual results could materially differ from these estimates.
Consolidation	The accompanying unaudited consolidated financial statements include the accounts of Medtronic plc, its wholly-owned subsidiaries, entities for which the Company has a controlling financial interest, and variable interest entities for which the Company is the primary beneficiary. Intercompany transactions and balances have been eliminated in consolidation.
Fiscal Period	The Company’s fiscal years 2021, 2020, and 2019 will end or ended on April 30, 2021, April 24, 2020, and April 26, 2019, respectively. Fiscal year 2021 is a 53-week year, with the extra week having occurred in the first fiscal month of the first quarter.
New Accounting Pronouncements	Recently Adopted Current Expected Credit Losses In June 2016, the Financial Accounting Standards Board (FASB) issued guidance which changes the methodology to be used to measure credit losses for certain financial instruments and financial assets, including trade receivables. The new methodology requires the recognition of an allowance that reflects the current estimate of credit losses expected to be incurred over the life of the financial asset. The Company adopted this guidance using the modified retrospective method in the first quarter of fiscal year 2021. The adoption of this guidance did not have a material impact to the Company’s consolidated financial statements.

Current Expected Credit Losses

In June 2016, the Financial Accounting Standards Board (FASB) issued guidance which changes the methodology to be used to measure credit losses for certain financial instruments and financial assets, including trade receivables. The new methodology requires the recognition of an allowance that reflects the current estimate of credit losses expected to be incurred over the life of the financial asset. The Company adopted this guidance using the modified retrospective method in the first quarter of fiscal year 2021. The adoption of this guidance did not have a material impact to the Company’s consolidated financial statements.
