As the Company has previously announced, the Company is focused on its ongoing transformation from a company with a broad portfolio of largely undifferentiated products to a more focused medical technology company that delivers unique and innovative health care solutions. The Company believes that this transformation will enable the Company to shift the portfolio from the mature, lower-growth markets where we have competed in the past by investing in technology and products that provide access to larger and faster growing markets. As such, we believe the growth in the near to mid-term will be driven by our high technology products including Auryon, Thrombectomy (which includes AngioVac, AlphaVac and thrombolytics) and NanoKnife. We will refer to these high technology products as our Med Tech business and we will refer to the remainder of the portfolio as our Med Device business.
