A method and device for the placement of sutures and for the purpose of approximating tissue. The invention relates to devices for approximation, ligation and fixation of tissue using a suture, to various constituent parts comprising said devices, and particularly to the placement of sutures into certain difficult to access ligamental structures, to the approximation of tissue separated by means of an endosurgical trocar being inserted into a body cavity, and to approximation, ligation, and fixation of body tissue using both traditional open surgical and endosurgical techniques and instruments. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off. The invention also provides for the placement of sutures for the endoscopic approximation, fixation, and ligation of tissues within a body cavity including the driving and retrieval of needle and suture combinations, and facilitating the tying of knots.

A high frequency electrosurgical power generator configured to produce electrical power at a frequency of about 1 to about 14 MHz and preferably having an essentially sinusoidal waveform with a voltage level up to 1,000 Vrms, and a current level up to 5 Amps. The output of the high frequency electrosurgical power generator is connected to an electrosurgical tool configured to receive the voltage and current produced by the electrosurgical power generator and deliver the voltage and current to an electrosurgical site. The output of the electrosurgical generator preferably is an essentially sinusoid waveform with a frequency between about 3 MHz and about 8 MHz, up to about 700 volts rms, up to about 2 amps, with a total power of up to 1,000 watts.

A system and method for managing, reducing, or eliminating the deleterious effects of the operation of energy emitting instruments on imaging systems. The system and method of the invention can be built into the structure of an imaging system, or can be configured to adapt to existing imaging systems. An embodiment of a system incorporating features of the invention has an interference bar detector coupled to an interference bar acquisition device which relays information regarding a bar of interference to a processor which identifies the position and velocity of the interference bar moving across an image frame or image display. Based on the position and velocity of the interference bar within the image frame, the processor then computes the necessary corrections to the gating and timing of the operation of the energy emitting instrument so as to fix the position of the interference bar at a perimeter of the image display. In another embodiment, a portion of an image frame which contains interference from the operation of an energy emitting instrument can be replaced with a corresponding portion of another image frame which is clear of interference. The invention allows for such replacement of interference scrambled portions of an image frame to occur without undue interruption of the continuous image frame generation, video stream or video display output of the imaging system.
