The staple of claim 4, wherein a cross section of the wire generally flattens out toward the engagement portion of the staple. 6. The staple of claim 1, wherein the engagement portion is extended in the longitudinal direction, relative to the remainder of the staple, for better engagement with the staple advancing device. 7. A surgical treatment device, comprising: an implantable surgical staple having a main body generally in the form of a coil, the main body having a sharp, tissue-penetrating tip at one end thereof and an engagement portion at an opposite end thereof, the engagement portion being constructed to engage a staple advancing device for longitudinal and rotational advancement of the staple into an implanted configuration, wherein the staple has a generally circular shape defining a circumferential path when viewed from an end of the staple, the engagement portion being generally disposed along the circumferential path, the staple being composed of a biocompatible material; delivery structure for supporting the surgical staple and delivering the surgical staple to a desired anatomical site of a patient; movement structure, operatively coupled with the delivery structure, for moving anatomical tissue into position for engagement by the staple; and a staple advancing device for rotationally and longitudinally advancing the staple through the anatomical tissue to hold the anatomical tissue in a desired configuration. 8. The surgical treatment device of claim 7, wherein the staple advancing device comprises a cylindrical body disposed generally parallel to the staple, rotation of the cylindrical body causing rotation of the staple through the anatomical tissue. 9. The surgical treatment device of claim 8, wherein the amount and direction of rotation of the cylindrical body causes rotation of the staple in a like amount and direction. 10. The surgical treatment device of claim 8, wherein the cylindrical body defines a recessed portion, the recessed portion engaging the engagement end of the staple for driving the staple through the anatomical tissue. 11. The surgical treatment device of claim 8, wherein the cylindrical body defines a generally hollow interior, the surgical treatment device further comprising viewing apparatus disposed within the hollow interior, the viewing apparatus allowing an operator of the surgical treatment device to view implantation of the staple in the anatomical tissue. 12. The surgical treatment device of claim 11, wherein the viewing apparatus comprises a cystoscope. 13. The surgical treatment device of claim 11, wherein the viewing apparatus extends within the coil of the staple. 14. The surgical treatment device of claim 8, further comprising a raised portion attached to the cylindrical body, rotational engagement of the raised portion by the fingers of an operator of the surgical treatment device causing rotation of the cylindrical body and implantation of the staple. 15. The surgical treatment device of claim 7, further comprising a hood disposed over the staple, the hood covering the sharp, tissue-penetrating tip of the staple during initial insertion of the surgical treatment device into a pati ent. 16. The surgical treatment device of claim 7, wherein the movement structure comprises a vacuum device for moving anatomical tissue into position for engagement by the staple. 17. A surgical treatment device, comprising: delivery structure for supporting a coil-shaped surgical staple and delivering the coil-shaped surgical staple to a desired anatomical site of a patient; movement structure, operatively coupled with the delivery structure, for moving anatomical tissue into position with respect to the coil-shaped surgical staple; and a staple advancing device for rotating the coil-shaped surgical staple into the anatomical tissue to hold the anatomical tissue in a desired configuration. 18. The surgical treatment device of claim 17, wherein the movement structure comprises a vacuum device for drawing desired tissue into a new anatomical position. 19. The surgical treatment device of claim 18, wherein the vacuum device comprises a syringe. 20. The surgical treatment device of claim 18, wherein the vacuum device comprises a vacuum pump. 21. The surgical treatment device of claim 18, wherein the movement structure comprises a blocking device, operatively coupled with the vacuum device, for preventing the vacuum device from applying vacuum to a portion of the anatomy of the patient. 22.
