| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Presentation | Basis of Presentation – The condensed unaudited interim financial statements do not include all disclosures, including certain notes required by accounting principles generally accepted in the United States of America (“GAAP”) on an annual reporting basis. The condensed unaudited interim financial statements have been prepared on the same basis as the annual financial statements. In management’s opinion, the condensed unaudited interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the condensed balance sheets, condensed statements of operations, condensed statements of redeemable convertible preferred stock and stockholders’ deficit, and condensed statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. The condensed unaudited interim financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2025 included in the Company’s prospectus dated May 7, 2026 filed pursuant to Rule 424(b)(4) with the U.S. Securities and Exchange Commission (the “SEC”) on May 8, 2026. The financial statements are presented in thousands, except for share and per share amounts. Certain prior period amounts presented in the Company’s Registration Statement on Form S-1 have been rounded to the nearest thousand to conform to the current period’s presentation. Accordingly, certain prior period figures may differ slightly from previously filed reports presented in whole dollars. Significant Accounting Policies – There have been no material changes to the Company’s significant accounting policies as described in the Company’s audited financial statements for the year ended December 31, 2025. |

| Reverse Stock Split | Reverse Stock Split – In connection with the IPO, on May 1, 2026 the Company effected a reverse stock split of its issued and outstanding common stock. All references to common stock issued and outstanding, stock options, loss per share and per share amounts presented in the accompanying financial statements and notes thereto have been retroactively adjusted for all periods presented to reflect the reverse stock split. The per share par value, authorized numbers of shares of the Company’s common stock and redeemable convertible preferred stock, issued and outstanding number of shares of redeemable convertible preferred stock, and redeemable convertible preferred stock warrants were not adjusted as a result of the reverse stock split. Instead, the conversion ratio was updated whereby each share of each series of Preferred Stock was convertible into shares of common stock on a basis. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates | Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions include, but are not limited to, stock compensation, valuation of common and preferred stock, valuation of warrant liability, product warranty liability, and redeemable convertible preferred stock tranche liability. Actual results could differ from those estimates. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Emerging Growth Company Status | Emerging Growth Company Status – The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”), enacted in 2012. Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued after the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segment Reporting | Segment Reporting – The Company operates and manages its business as a reportable and operating segment. Operating segments are defined as components of an enterprise where separate financial information is evaluated regularly by the chief operating decision maker (CODM) in deciding how to allocate resources and assess performance. The Company’s CODM is the , who reviews financial information on a company-wide basis for purposes of allocating resources and assessing financial performance and does not regularly review expenses or financial results on a more granular level. For additional segment reporting information, refer to Note 14. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deferred Offering Costs | Deferred Offering Costs – Deferred offering costs consisted of legal and accounting fees incurred directly related to the Company's IPO. Upon completion of the IPO, these costs were recorded as a reduction of the offering proceeds included within additional paid-in capital. Unpaid offering costs during the three months ended March 31, 2026 were $2.2 million. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventory | Inventory – Inventory costs are comprised primarily of finished goods and raw materials and include the acquisition costs of raw materials and components, in addition to direct labor and overhead. All inventory is stated at the lower of cost or net realizable value and is accounted for on a first in, first out (FIFO) basis. The balance of inventory is as follows (in thousands):
The Company performs an assessment of the recoverability of inventory during each reporting period, and, if applicable, writes down any excess and obsolete inventories to their estimated net realizable value in the period in which the impairment is first identified. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required. There were no expenses recorded for excess inventory or other impairments for each of the three months ended March 31, 2026 and March 31, 2025. |

| Recently Issued Accounting Standards | Recently Issued Accounting Standards – On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. This guidance is effective for annual periods beginning after December 15, 2024; however, as an EGC, the Company has elected to use the extended transition period for adopting new or revised accounting standards, and therefore the guidance will be effective for the Company for the year ended December 31, 2026. The adoption of ASU 2023-09 is expected to have a disclosure-only impact on the Company’s financial statements for the year ended December 31, 2026. The Company is currently evaluating the impact of this pronouncement on the disclosures in its financial statements. On November 4, 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires more detailed disclosures about specified categories of expenses (including employee compensation, depreciation, and amortization) included in certain expense captions presented on the face of the income statement. This ASU is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments may be applied either (i) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (ii) retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this pronouncement on the disclosures in its financial statements. On November 26, 2024, the FASB issued ASU 2024-04, Debt – Debt with Conversion and Other Options (Subtopic 470-20), which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion rather than as extinguishment of debt. The amendments may be applied on either a prospective or a retrospective basis. This ASU is effective for fiscal years beginning after December 15, 2025, and interim periods within those annual reporting periods. The Company adopted as of January 1, 2026, on a prospective basis and it did not have a material impact on its financial statements. On December 8, 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow-Scope Improvements, which is intended to improve the navigability of interim disclosures, clarifies when Topic 270 applies, and provides additional interim disclosure guidance, including a principle to disclose material events since the most recent annual reporting period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. This ASU is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027; however, as an EGC, the Company has elected to use the extended transition period for adopting new or revised accounting standards, and therefore the guidance will be effective for the Company for interim periods within annual periods beginning after December 15, 2028. The Company is currently evaluating the impact of this pronouncement on its financial statements. |
