An ultrasonic surgical device for the application of ultrasonic energy is disclosed. The surgical device has a housing and an acoustic assembly having a solid core waveguide. The waveguide extends from the housing and has a novel end effector at the distal end for the conduction of ultrasonic energy thereto. Two novel end effectors are described having an embedding surface at the distal end, and a coagulating surface extending from the embedding surface. The first novel end effector has a cylindrical shaft, an embedding surface, and an angled coagulating surface. The second novel end effector has a truncated cone having a circumferential coagulating surface and a distal embedding surface.
1. An ultrasonic surgical device and patch combination for repairing a defect in tissue comprising:a) a patch for placement over a defect in tissue; b) a housing; c) an acoustic assembly for the generation of ultrasonic energy, said acoustic assembly including a waveguide extending from said housing
