Lender questions nSpire Health’s viability

LONGMONT — nSpire Health Inc., a developer of respiratory medical devices and software for respiratory information systems that filed for Chapter 11 bankruptcy protection in April, is unlikely to return to viability, according to nSpire’s primary creditor.

The company has been effectively inoperational for several months, court documents filed by creditor Montage Capital allege.

In a flurry of back-and-forth filings in U.S. Bankruptcy Court in Denver over the past several weeks, competing narratives about nSpire’s woes have emerged: nSpire accuses its creditor of unfairly stymying efforts to continue operations, while Montage alleges lack of investment and mismanagement have sealed the firm’s fate.
