Covidien Ltd. (COV) will acquire medical-device maker VNUS Medical Technologies Inc. (VNUS) for $440 million as it looks to expand its presence in the vascular market.

Unlike many of its rivals, who are being hurt by hospital-spending cutbacks, Covidien sells mostly less-expensive medical products and equipment that won't pressure budgets.

Covidien will pay $29 a share in the all-cash offer, a 36% premium over VNUS's Thursday closing price. Both companies shares were inactive premarket.

The deal is expected to close by June 30; if so it would slighly cut into earnings for the year ending Sept. 30 excluding acquisition-related charges.

San-Jose, Calif.-based VNUS makes devices for minimally invasive treatment of venous reflux disease, a cause of varicose veins that can result in leg pain, swelling, fatigue and skin ulcers. Its products include the VNUS Closure system, which uses a radiofrequency catheter to heat and close diseased veins. In trials, the system has been shown to be as effective as vein stripping, a surgical procedure, with fewer side effects and faster recovery.
