Medtech Insight recorded 17 merger or acquisition deals in March, a rise from the nine deals recorded last month and in the same period last year. It was a busy month for Boston Scientific, which racked up two acquisitions, paying $460m for urology device maker NxThera and an undisclosed price for endoscopy firm EMcision.

Complete list of all 91 FDA device-related warning letters released by the agency last year. The upshot: 73 domestic and 18 foreign manufacturers were sent letters.

Twelve FDA close-out letters were released in September.

Anybattery Inc. sold replacement batteries without premarket approval or clearance from FDA; EMcision used electronic signatures to approve numerous procedures despite not having electronic signature systems; and more. Three warning letters were listed by FDA this week.
