Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and New Accounting Standards	Our accompanying unaudited consolidated condensed financial statements as of March 31, 2018 and for the three months ended March 31, 2018 and 2017 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for annual financial statements. Our consolidated condensed balance sheet at December 31, 2017 has been derived from the audited financial statements at December 31, 2017, but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations of Cytori Therapeutics, Inc., and our subsidiaries (collectively, the “Company”) have been included. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. These financial statements should be read in conjunction with the consolidated financial statements and notes therein included in our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on March 9, 2018.

Recently Issued and Recently Adopted Accounting Pronouncements	Recently Issued and Recently Adopted Accounting Pronouncements Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases. Under this new guidance, at the commencement date, lessees will be required to recognize (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This guidance is not applicable for leases with a term of 12 months or less. The new standard is effective for annual reporting periods, and interim periods within those periods, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact that this standard will have on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, to simplify how all entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value. This update is effective for annual periods beginning after December 15, 2019, and interim periods within those periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact that this standard will have on our consolidated financial statements. Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is based on the principle that revenue should be recognized in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the transfer of promised goods or services. ASU 2014-09 and all subsequent amendments (collectively, the “new standards”) may be applied using either the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We have adopted the standards beginning this first quarter of 2018 using the modified retrospective method. Overall, the timing or amounts related to the revenue recognition under the new standards did not differ from our previously applied revenue recognition policy. Our product revenues are recognized at a point in time, which is when control transfers to the customer. We have made an accounting policy election to treat shipping and handling activities that occur after the customer obtains control of the goods as fulfillment costs. There was no cumulative effect of applying the new standards as of the adoption date on January 1, 2018. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Restricted Cash, which requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. The adoption of this standard, in the first quarter of 2018, changed the presentation of our statement of cash flows to include our restricted cash balance with the non-restricted cash balances. The new guidance did not have a material impact on the Company's consolidated financial statements. Cash, cash equivalents, and restricted cash reported on the Consolidated Condensed Statements of Cash Flows includes restricted cash of $0.4 million, $0.4 million, $0.7 million, and $40 thousand as of December 31, 2016, March 31, 2017, December 31, 2017 and March 31, 2018, respectively.
Use of Estimates	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Our most significant estimates and critical accounting policies involve recognizing revenue, reviewing goodwill and intangible assets for impairment, determining the assumptions used in measuring share-based compensation expense, measuring expense related to our in-process research and development acquisition, and valuing allowances for doubtful accounts and inventory reserves. Actual results could differ from these estimates. Management’s estimates and assumptions are reviewed regularly, and the effects of revisions are reflected in the consolidated financial statements in the periods they are determined to be necessary.
Revenue Recognition	The Company’s contracts with customers only include one performance obligation (i.e., sale of the Company’s products). Typically, if there are multiple items included on a single order, they are delivered at the same time. Revenue is recognized at a point in time when delivery is completed and control of the promised goods is transferred to the customers. Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for those goods. The Company’s contracts do not involve financing elements as payment terms with customers are less than one year. The sale arrangements do not include any variable consideration. Advance payments from customers are recorded as deferred revenue. Shipping and handling activities that occur after the customer obtains control of the goods are considered part of the Company’s obligation to transfer the products and therefore are recorded as direct selling expenses, as incurred.
