Lifecell Corporation pioneered the field of tissue repair and reinforcement with biologic materials utilizing proprietary processing techniques to remove cells and other impurities from allograft and xenograft dermis, thus creating an ideal “scaffold” material for tissue repair, reinforcement, and replacement applications. Vertical was a shareholder of Lifecell from 2001 until the Company’s acquisition by KCI in 2008 for approximately $1.8 billion. During its seven years as a shareholder, Vertical assisted Lifecell in establishing corporate partnerships with several Vertical portfolio companies.

Lutonix was acquired by CR Bard in 2011 in a transaction valued at over $300 million including future earnouts. Tony Chou served on the Board of Directors.
Masimo Corporation was founded in 1989 by Joe Kiani, a 25 year old entrepreneur from Iran, to develop a revolutionary improvement to pulse oximetry systems. At the time, the pulse oximetry market was dominated by a single competitor, Nellcor. Joe and his team worked for nearly six years to perfect their new technology - Masimo SET - and introduced it to the market in 1996. Despite extraordinary resistance by Nellcor, which included patent infringement and anticompetitive activity, Masimo's superior technology ultimately became the standard of care in pulse oximetry. Masimo has since introduced many additional revolutionary technologies, including the first non-invasive measurement of hemoglobin. Masimo has annual sales of approximately $400 million and a public market cap of $2 billion. The Vertical Group invested in an early venture round in 1994. Jack Lasersohn joined the Masimo Board of Directors at that time and continues to serve on it today.
Metabolix was founded as a spin out from MIT in 1992 to develop a new class of biopolymers assembled by genetically engineered E. coli bacteria. The polymers, called PHBs, are biodegradable, but share many of the attractive properties of mass produced, commercial-grade plastics such as polyesters. In addition, there was some evidence that PHBs might be attractive for biological implants, as they would be both degradable, but also highly biocompatible. Vertical led the first venture round for the company in 1992 and participated in nearly one dozen subsequent rounds over the next decade. In 2006, the company completed a $400 million joint venture with ADM to commercialize its revolutionary biodegradable plastics for the commercial market and successfully completed an IPO in 2007 at more than a $600 million market value. It had previously spun out a company, Tepha, in 2000, to develop medical applications of PHBs. Ed Giles has served on the Metabolix Board since its founding and Jack Lasersohn served on the Board from 1998 through 2007. Richard Emmitt and Ed Giles continue to serve on the Tepha Board, which remains an active Vertical portfolio investment.
OsteoBiologics Inc. developed proprietary and patented bioabsorbable polymer materials utilized for the repair and replacement of injured bone, cartilage, and other skeletal tissues. During 2003 OBI received its first FDA marketing clearances. In July, 2006 OBI was acquired by Smith & Nephew for approximately $75 million. Richard B. Emmitt served on the OBI Board of Directors.
Proteolix, Inc. is a bio-pharmaceutical company that developed drugs which target the activities of the proteosome. The founders are among the world’s leading experts on the proteosome and their previous work led directly to the development of Velcade, the leading FDA approved drug for the treatment for multiple myeloma. The Proteolix drug, Carfilzomib, has completed several Phase II clinical trials that demonstrate efficacy equivalent or superior to Velcade without the latter drug’s dose limiting toxicity. These clinical results also suggest that the Proteolix drug may have superior efficacy compared to Celgene’s Revlimid, with a similar toxicity profile. In early testing, Carfilzomib also has demonstrated efficacy against both renal cell and small cell lung cancer. Proteolix was acquired by Onyx Pharmaceuticals in 2009 for total consideration which may exceed $800 million.
SciMed Life Systems was one of the pioneers in the development of products used in the procedure called PTCA or balloon angioplasty which treats blocked coronary arteries. The predecessors of the Vertical Group led the early financings of the company and were its principal shareholders. Richard Emmitt served on the SciMed Board of Directors from 1984 until the company’s merger with Boston Scientific in 1995. At the time of closing, the merger valued SciMed at approximately $1.0 billion with SciMed shareholders receiving approximately on-third of the equity of the combined companies.
