Abstract: A surgical system includes a drive unit on a support. The drive unit includes motors or other actuators and a plurality of output elements arranged such that operation of each drive unit linearly translates a corresponding one of the output elements. A surgical device has an input subsystem carried at the proximal end of the shaft. The input subsystem includes linearly translatable input elements or pistons. The input and output elements are positioned such that operation of an actuator linearly translates an output element, causing linear translation of a corresponding input element. The input elements deliver linear motion to a rotary conversion system which converts the linear motion to rotary motion and delivers the rotary motion to a shaft of the surgical device, causing axial rolling of the surgical device or its distal end effector. A sterile drape is positionable between the input elements and the output elements.

Abstract: An electrode connectable to a pulse generator is disclosed. The electrode includes therapeutic terminals configured to deliver the pulse to a patient, first and second electrical pulse inlet holes, and a first pulse input terminal. The first pulse input terminal is in the first electrical pulse inlet hole and is spaced apart from an entrance to the first electrical pulse inlet hole by more than about 2.5 cm. Also, first pulse input terminal is connected with one or more of the therapeutic terminals. The electrode also includes a second pulse input terminal, where the second pulse input terminal is in the second electrical pulse inlet hole and is spaced apart from an entrance to the second electrical pulse inlet hole by a distance greater than about 2.5 cm. Also, the second pulse input terminal is electrically connected with one or more of the therapeutic terminals.

Abstract: A method for automatically fixing sutures to secure a valve sleeve including an annular cuff and a replacement heart valve to an annulus formed in a patient's heart, includes the steps of removing an existing heart valve thereby forming an annulus in the patient's heart, and placing a first cylinder having a first end and a second end and an interior surface and an exterior surface and comprising first securing means formed on the exterior surface adjacent to the second end of the first cylinder, in which the first cylinder includes a valve sleeve having an annular cuff, such that the annular cuff surrounds the exterior surface adjacent to the first end of the first cylinder. Moreover, the method includes creating a blood-tight seal between the cuff of the valve sleeve and the annulus, and securing the plurality of sutures between the first cylinder and the second cylinder.

Abstract: An apparatus for automatically fixing sutures used in the surgical replacement of a heart valve, includes a first cylinder having a first end and a second end and an interior surface and an exterior surface. An annular lip is formed on the exterior surface adjacent to the second end of the first cylinder. The apparatus further includes a second cylinder having second securing means formed on an interior surface of the second cylinder, such that the second securing means corresponds to and are adapted to fixedly engage the first securing means.
