Abstract (en)
[origin: WO9816157A1] The present invention relates to devices and methods for improving blood flow to the heart of a patient. One device includes a transducer assembly (36) disposed in a housing. An end effector (40) is operatively coupled to the transducer assembly (36) and includes a channel-forming member. The channel-forming member is capable of creating channels in the heart of a patient. A method of improving the blood flow to the heart of a patient is also provided. The method includes the steps of providing a surgical device having an end effector (40), energizing the surgical device to cause the end effector (40) to vibrate, contacting the end effector (40) with a ventricular wall of the heart, advancing the end effector (40) into the ventricle wall, and creating a channel in the ventricle wall with the end effector (40).
