Tyco's US Surgical division has filed a lawsuit against Ethicon Endo-Surgery, accusing it of infringing four US Surgical patents. The suit, filed in a district court in Connecticut, relates to Ethicon's UltraCision Harmonic Scalpel, which has a curved blade. US Surgical says the patents in question relate to ultrasonic dissection and coagulation systems. It is seeking an injunction on the manufacture and sale of the instrument, and compensatory damages.
