BTG has paid $20 million in cash to buy Novate, and may pay a further $130 million depending on the device hitting certain sales-related milestones, the UK company said on Friday.

The device, Sentry, received approval recently in the United States for use as in implant to prevent blood clots in leg veins from travelling to the lungs.

BTG plans a U.S. launch of Sentry in the second half of its current fiscal year.

The acquisition follows BTG's deal last year to buy U.S.-based cardiovascular catheter maker Roxwood Medical.(This story corrects first paragraph and headline to say Novate is Ireland-based, not U.S.-based)
