Minimally invasive surgery is performed without making a major incision or opening, resulting in less trauma for the patient and yielding significant cost savings. These result from shorter hospitalization times and reduced therapy requirements. Other benefits of minimally invasive surgery are less pain, less need for postsurgical pain medication, less scarring, and less likelihood of complications related to the incision.
Thus, minimally invasive surgery is defined either as based on the operative procedure (e.g., small incisions) or the outcome (reduced surgical complications or costs). However, minimally invasive is not the same as minor surgery. Some "minimally invasive" procedures, e.g., coronary artery bypass surgery, still are major operations requiring a hospital stay.
In minimally invasive surgery, a miniature camera is introduced into the body through a small incision. It transmits images to a video monitor, enabling the physician to diagnose and, if necessary, treat a variety of conditions. To do this, the physician inserts surgical instruments and auxiliary devices, such as irrigation and drainage devices, through one or more small incisions.
SCOPE OF STUDY
METHODOLOGY AND INFORMATION SOURCES
The findings and conclusions of this report are based on information gathered from manufacturers and users of minimally invasive surgical devices, as well as other informed sources. Interview data were combined with information gathered from an extensive review of secondary sources, such as trade publications, trade associations, company literature and online databases, to produce the market estimates contained in this report.
The base year for analysis and projection is 2005. At the time this report was prepared (early 2006), year-end data for 2005 were not yet universally available. Where necessary, market estimates for 2005 were developed using interim (partial) data for 2005, combined with historical data for the years 2002-2004.
With 2005 as a baseline, market projections were developed for 2006-2011. These projections are based on a consensus of primary contacts combined with BCC Research's understanding of the key market drivers and their impact from a historical and analytical perspective. The analytical methodologies used to generate the market estimates are described in detail in the section on Detailed Market Projections.
All dollar projections presented in this report are in 2005 constant dollars.
