The flotation, which aims to raise £35m, will separate Spacelabs from Nasdaq-listed OSI, whose other interests are in security and
fibre optic manufacturing.
Spacelabs had revenues of £111m in the year to 30 June 2005, up from £6m in the year to 30 June 2003 as a result of the acquisitions of Spacelabs Medical and Blease Medical Holdings.
The firm's directors, including chief executive Deepak Chopra, are hoping to increase the brand recognition of Spacelabs' patient monitors to augment sales of complementary medical equipment.
