Home health products manufacturer Invacare (NYSE:IVC) has acquired a negative-pressure wound therapy system to be sold through its rental business for long-term care providers. But the Elyria, Ohio-based company wouldn’t reveal much more than that, such as the deal’s price or the company it acquired the technology from. Invacare revealed the acquisition in its (pdf) third-quarter earnings announcement. “This line of products will add to the company’s current offering of wound therapy solutions available through Invacare’s rental services to long-term care providers,” Invacare said at the time. “The company anticipates this to be a long-term growth platform.”
