and for the

three

and

six

months ended

are unaudited. The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information and on a basis consistent with the annual financial statements and, in the opinion of management, reflect all adjustments which include only normal recurring adjustments, necessary to present fairly our financial position as of

not

necessarily indicative of the results to be expected for the year ending

December 31, 2017

or for any other interim period or for any other future year.

These condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s Annual Report on Form

Going Concern and Liquidity [Policy Text Block]

(b)

Liquidity

The Company has incurred net losses and negative cash flows from operations since its inception and had an accumulated deficit of

$66

million as of

June 30, 2017.

Management expects operating losses and negative cash flows to continue through at least the next several years.

Based on management’s current plans, management believes cash and cash equivalents of

$15.1

million and short-term investments of

$1.8

million as of

June 30, 2017

are sufficient to fund the Company into the

third

quarter of

2018.

In order to continue to further the development of the Company’s lead therapeutic candidate, the CardiAMP cell therapy system, and the Company’s

second

therapeutic candidate, the CardiALLO cell therapy system, through and beyond

2018,

we will be required to raise additional capital. The Company plans to raise additional capital, potentially including debt and equity arrangements, to finance its future operations. If adequate funds are

not

available, the Company

may

be required to reduce operating expenses, delay or reduce the scope of its product development programs, obtain funds through arrangements with others that

may

require the Company to relinquish rights to certain of its technologies or products that the Company would otherwise seek to develop or commercialize itself, or cease operations. While the Company believes in the viability of its strategy to raise additional funds, there can be

assurances to that effect.

Use of Estimates, Policy [Policy Text Block]

(c)	Use of Estimates

The preparation of the financial statements in accordance with U.S. GAAP requires Company management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Significant items subject to such estimates and assumptions include the useful lives of property and equipment; allowances for doubtful accounts and sales returns; inventory valuation; fair value of the convertible preferred stock warrant liability; fair value of the maturity date preferred stock warrant liability; fair value of the convertible shareholder notes derivative liability; and share-based compensation.

Consolidation, Policy [Policy Text Block]

(d)

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany accounts and transactions have been eliminated during the consolidation process.

Investment, Policy [Policy Text Block]

(f )	Investments

Short-term investments consist of debt securities classified as available-for-sale and have maturities greater than

days, but less than

365

days from the date of acquisition. All investments are carried at fair value based upon quoted market prices. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are reported as a component of accumulated other comprehensive loss. Realized gains and losses on the sale of marketable securities are determined using the specific-identification method and recorded in other income (expense), net on the accompanying unaudited condensed consolidated statements of operations. The Company periodically evaluates these investments for other-than-temporary impairment.

Premiums and discounts on debt securities are amortized or accreted over the life of the security as an adjustment to yield using the effective-interest method. Such amortization and accretion is reported as interest income (expense) in the statement of operations. Dividend and interest income are recognized when earned.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncement

March 2016,

the FASB issued ASU

2016

09,

Compensation - Stock Compensation (Topic

718

): Improvements to Employee Share-Based Payment Accounting (ASU

2016

). The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification in the statement of cash flows and forfeitures. The Company adopted ASU

2016

effective

January 1, 2017.

The impact of adopting ASU

2016

resulted in the following:

●

We classified the excess income tax benefits from stock-based compensation arrangement as a discrete item within income tax expense, rather than recognizing such excess income tax benefits in additional paid-in capital. The adoption of this guidance had

material impact to our condensed consolidated financial statements due to a full valuation allowance recognized against our deferred tax assets.

●

We elected to recognize forfeitures as they occur. The cumulative effect adjustment as a result of the adoption of this guidance on a modified retrospective basis was insignificant.

●

We applied the change in classification of cash flows resulting from excess tax benefits and cash paid by us when directly withholding shares for tax-withholding purposes on a retrospective basis. The adoption of these provisions did

not

result in changes in our condensed consolidated statements of cash flow.

There were

other material impacts to our condensed consolidated financial statements as a result of adopting this updated standard.

Recently Issued Accounting Pronouncements

May 2014,

the FASB issued ASU

No.

2014

09,

Revenue from Contracts with Customers (Topic

606

), which provides comprehensive guidance for revenue recognition. ASU

2014

affects any entity which either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The core principle of the guidance provides that a company should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The new standard can be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of the change recognized at the date of the initial application in retained earnings.

August 2015,

the FASB issued ASU

2015

Revenue from Contracts with Customers, which deferred the effective date for implementation of the standard. Public entities are to apply the new standard for annual and interim reporting periods beginning after

December 15, 2017

and earlier application is permitted only as of annual reporting periods beginning after

December 15, 2016,

including interim reporting periods within that reporting period. The Company has

not

elected early adoption. The Company has formed a task force that is in process of assessing the Company’s customer contracts and the potential impacts the standard

may

have on previously reported revenues and future revenues. Given the relatively small volume of revenue arrangements, the Company believes that the analysis will be completed in sufficient time to adopt the new standard when required. The Company expects to elect the cumulative effect adoption method.

February 2016,

the FASB issued ASU

2016

Leases (Topic

842

), which supersedes existing guidance on accounting for leases in “Leases (Topic

840

)” and generally requires all leases to be recognized in the consolidated balance sheet. ASU

2016

is effective for annual and interim reporting periods beginning after

December 15, 2018;

early adoption is permitted. The Company does

not

plan to elect early adoption. The provisions of ASU

2016

are to be applied using a modified retrospective approach. The Company is currently assessing the future impact of this ASU on its consolidated financial statements.

May 2017,

the FASB issued ASU

2017

Compensation – Stock Compensation (Topic

718

) Scope of Modification Accounting. The amendments in ASU

2017

provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic

718.

The adoption of ASU

2017

09,

which will become effective for annual periods beginning after

December 15, 2017,

not

expected to have a material impact on the Company’s consolidated financial statements.

Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, and the American Institute of Certified Public Accountants did

not

or are

not

believed by management to have a material impact on the Company’s financial statement presentation or disclosures.

- Definition
