This medical device company has pioneered a proprietary minimally invasive surgical implant system, which is called iFuse, to fuse the sacroiliac joint to treat sacroiliac joint dysfunction that often causes severe lower back pain. Since the firm introduced iFuse in 2009, more than 34,000 procedures have been performed by over 1,700 surgeons, in the United States and 33 other countries.
Published clinical studies have shown that 15% to 30% of all chronic lower back pain is associated with the sacroiliac joint. The company believes iFuse is currently used in the majority of minimally invasive surgical fusions of the sacroiliac joint in the United States.
The company detailed its finances in the filing as follows:
In 2016 and 2017, we generated revenue of $42.1 million and $48.0 million, respectively, a growth rate of 14%, and incurred net losses of $20.6 million and $23.0 million, respectively. Our gross margins were 88% and 89% for 2016 and 2017, respectively. For the six months ended June 30, 2017 and 2018, we generated revenue of $22.5 million and $26.4 million, respectively, a growth rate of 17%, and incurred net losses of $12.5 million and $7.3 million, respectively. Our gross margins were 89% and 92% for the six months ended June 30, 2017 and 2018, respectively. The number of iFuse procedures performed in the six months ended June 30, 2017 and 2018 was 2,739 and 3,200, respectively.
