A surgical suturing apparatus for performing a surgical procedure with a body cavity includes a flexible member having a distal end attached to a suturing body for insertion of the suturing body through an orifice and into a body cavity. The suturing body includes a suture housing in which a needle and drive assembly are housed for movement of the needle with a suture secured thereto about an arcuate path facilitating application of the suture to tissue. A non-visible spectrum sensing member is associated with the suturing body for communicating a parameter of the procedure to a visual display.
