We note the revisions made in response to prior comment 10 and we reissue the comment in part. Please expand to clarify why HealthCor's model reflected a materially reduced valuation ($570 million) of Hyperfine and Liminal as compared to the one initially Arthur Cohen FirstName LastNameArthur Cohen HealthCor Catalio Acquisition Corp. Comapany 21, September NameHealthCor 2021 Catalio Acquisition Corp. September Page 2 21, 2021 Page 2 FirstName LastName proposed on April 13 by Hyperfine and Liminal (in excess of $800 million). 3. We note your response to prior comment 13 but are unable to locate changes addressing the comment. As previously requested, please revise the April 13 entry to clarify the actual combined dollar valuation proposed by Hyperfine and Liminal, and tell us whether that proposal provided separate valuations for Hyperfine and Liminal. Certain Projected Financial Information, page 117 4. We note your response to comment 15. Please address the following: It appears that one of the material assumptions underlying projected revenue growth is the expected recurring revenue from the subscription-based business. Specifically, as the base of installed units grows, the cumulative carry-over effect will result in increased revenue each successive year as the business continues to grow. Please further expand your disclosures to further discuss the assumptions underlying the different projected revenue streams, which appear to be unit sales and subscription- based services; and As previously requested, please explain how management and the Board considered and relied upon these projections, particularly in light of the limited historical commercial operations of Hyperfine, Inc. and Liminal Sciences, Inc. 5. We note your response to prior comments 17, 18 and 19 but are unable to locate changes that address the comments. As previously requested, please revise to address the following: Clarify whether the financial projections disclosed here were the only projections or material financial information that Hyperfine and Liminal presented to the HealthCor board for purposes of negotiating the terms of the Business Combination Agreement. If not, please disclose such information, forecasts and/or projections; Describe how the parties were able to negotiate what proved to be the final valuations and reach agreement on other material terms in May if HealthCor did not receive financial projections from Hyperfine and Liminal until June 10; Disclose what the HealthCor board did with the projections it received and whether it used these same projections, or altered ones, in its financial model(s) and analyses. Recommendation of HealthCor's Board of Directors, page 124 6. We note your response to prior comment 20 but are unable to locate changes made in response.

U.S. Federal Income Tax Considerations, page 153 7. We note the revisions you made in response to prior comment 21. We further note that counsel does not appear to opine on whether or not HealthCor is likely to be classified as a Arthur Cohen HealthCor Catalio Acquisition Corp. September 21, 2021 Page 3 PFIC and, if so, what the material tax consequences to U.S. Holders will be. Counsel's opinion should not assume the tax consequence at issue or any legal conclusion underlying the opinion. Please revise the tax opinion and related sections accordingly. Refer to Staff Legal Bulletin No. 19, Part III.C.3 for guidance. Unaudited Pro Forma Condensed Combined Financial Information, page 164 8. We note your response to comment 27. It appears that the pro forma statements of operations do not include certain expenses that are not expected to have a continuing impact, including nonrecurring management compensation expense discussed in Notes 3(h) and (i) on page 174 and transaction costs discussed in Note 3(b) on page 171. We remind you of the updated pro forma financial information guidance provided in SEC Release 33-10786, which amended Article 11 of Regulation S-X, under which it would appear these expenses should be reflected in your pro forma statements of operations. Please revise your pro forma statements of operations or further advise. Refer to 11-02 (a)(6)(i)(B) of Regulation S-X. 9. We note your response to comment 28. The most significant adjustments on your pro forma statements of operations are for compensation expense related to various equity awards. In this regard, please address the following: We continue to believe additional disclosures should be provided to discuss the most significant underlying assumptions used to determine the compensation expense in Note 3(f), 3(g), and 3(h)(2). For example in Note 3(f), you note that the grant date fair value of the awards were estimated using the Monte Carlo simulation; however it is not clear what significant assumptions were used in the simulation to arrive at the grant date fair value; and It appears that adjustment 3(f) only reflects certain Earn-Out shares discussed on page 168. Please further clarify in your disclosures the amount of shares included in this adjustment as well as how you determined which shares to include. 10. We note your response to comment 36. Your response indicates that the only recent equity issuances were Hyperfine options granted in April 2021 and Liminal options granted in May 2021. As previously requested, please help us better understand how the fair value of the common stock of Hyperfine and Liminal which was used to to value these issuances reconciles to the valuations as indicated based on the terms of the Business Combination. Please also clarify whether these are the options discussed in Note 3(h)(2) to the pro forma statements of operations. Business of Hyperfine and Liminal, page 183 FirstName LastNameArthur Cohen 11.

Please address the following: Your disclosures on page F-49 indicate that manufacturing overhead costs primarily include the allocation of labor costs incurred related to inventory acquired or produced but not sold during the respective period.
