Entellus Medical

Entellus Medical, founded in 2006 by Thomas Ressemann and Peter Keith, is a medical technology company specializing in minimally invasive treatments for ear, nose, and throat (ENT) conditions, with a primary focus on chronic sinusitis. The company's core business revolves around developing and commercializing products for balloon sinus dilation, a procedure that reshapes sinus pathways without the need for tissue or bone removal. This approach is designed to be performed in a physician's office under local anesthesia, offering a cost-effective alternative to traditional functional endoscopic sinus surgery (FESS) with benefits such as faster recovery times and less bleeding.

The company's flagship product line is the XprESS™ Multi-Sinus Dilation System, which enables ENT physicians to open obstructed sinus drainage pathways. In addition to balloon dilation devices, Entellus developed a shaver system for more advanced procedures like polyp removal and septoplasty. The company's business model focused on selling these single-use devices and systems directly to ENT physicians and hospitals in the United States and Canada. Its primary clients are ENT specialists seeking effective and less invasive treatment options for their patients.

After its founding, Entellus Medical went public with an IPO in January 2015. In July 2017, the company acquired Spirox, Inc., which added the LATERA® Absorbable Nasal Implant to its portfolio for treating nasal airway obstruction. This acquisition was a significant milestone before another major corporate change. In December 2017, Stryker Corporation announced a definitive agreement to acquire Entellus Medical for approximately $662 million. The acquisition was completed in February 2018, and Entellus Medical became a wholly-owned subsidiary of Stryker, complementing Stryker's existing ENT business.
