One device in accordance with the present invention includes a surgical device for creating channels in tissue of a patient. The device includes a catheter defining a lumen and a transducer assembly carried by the catheter along a lengthwise dimension of the catheter. An end effector is operatively coupled to the transducer assembly and extends distally relative to the transducer assembly. The end effector has a vibrating channel-forming tip wherein the channel-forming tip is adapted to create channels in the heart of a patient. A method in accordance with the present invention includes the steps of inserting an end effector having a tip into a patient, placing the tip of the end effector in direct contact with a surface of the heart, energizing the end effector to cause the tip to vibrate, piercing through the surface of the heart with the tip to create a channel, and removing the end effector.
