A system, apparatus and method for stitching are described. One embodiment includes a sewing head including a needle; an arm assembly that is disposed relative to the sewing head so as to allow a garment to be placed between the sewing head and the arm assembly; and a non-planer needle plate coupled to the arm assembly that includes an aperture that is disposed so as to allow the needle to project through the aperture after the needle has moved through the garment.

Stitching system and method

The invention provides a sewing cuff assembly for mounting to the body of a heart valve prosthesis. The sewing cuff assembly comprises a resiliently deformed spring for exerting a force directed toward the orifice structure. When a torque is applied to the valve, the force results in a rotation-resisting torque sufficient to resist rotation during normal operation of the valve after implantation but low enough to permit assisted rotation, as during surgery.

An electrosurgical apparatus for cutting tissue and for ablating occlusions includes a pulse generator for selectively generating a train of pulses of electrical energy for application to a wire having an attached electrode, the generator having a variable output impedance, the wire and the electrode being at least part of a load impedance. The apparatus senses the load impedance relative to the output impedance and adjusts the output impedance to match the load impedance. The generator produces pulses of variable energy, measures the relative electrical energy produced by an arc in response to a pulse, compares the relative electrical energy to a predetermined value to determine an energy difference, and adjusts the energy of a subsequent pulse to reduce the energy difference for the subsequent pulse toward zero.
