Boston follows Medtronic's footsteps and buys into TAVI space

Boston Scientific is to buy outright a company in its investment portfolio, Sadra Medical. The firm specialises in percutaneous transcatheter aortic valve implantation (TAVI) technology and the acquisition follows in the footsteps of heart rival Medtronic, which last year bought two venture-backed TAVI companies – CoreValve and Ventor Technologies – for just under $1bn (www.clinica.co.uk, 2 March 2009).
