METHOD AND APPARATUS FOR PROVIDING ACCESS TO A PRESACRAL SPACE
First Claim
1. A method of providing access to a presacral space, the method comprising:
- making an incision through the patient'"'"'s skin adjacent to the coccyx;
inserting an elongated guide assembly through the incision to locate the guide assembly against the anterior surface of the sacrum, the elongated guide assembly having a guide assembly proximal end and a guide assembly distal ends, said guide assembly comprising an elongated tubular member having a tubular member lumen extending between a proximal tubular member end and a distal tubular member end;
advancing the guide assembly distal end along the anterior surface in the cephalad direction until the guide assembly distal end is at a target area within the presacral space; and
advancing the tubular member distal end to the target area, whereby the tubular member provides a percutaneous tract over or through the tubular member from the incision site to the target area within the presacral space.

Abstract
Methods and apparatus for providing percutaneous access to the presacral space in a minimally invasive, low trauma, manner. A number of related methods and surgical tool sets form a percutaneous pathway from an incision through the patient'"'"'s skin adjacent to the coccyx and inserting an elongated guide assembly through the incision to locate the guide assembly against the anterior surface of the sacrum to access a presacral target point. The provision of the percutaneous pathway described herein allows for the introduction of therapeutic devices or media, diagnostic instruments, and/or drug delivery to the presacral space.

23. An elongated guide assembly for accessing a presacral space for therapeutic or diagnostic assessment of the presacral space, comprising:
an elongated tubular member having a tubular member lumen extending between a proximal tubular member end and a distal tubular member end, the distal tubular end configured to insert through an incision through the patient'"'"'s skin adjacent to the coccyx, whereby the tubular member provides a percutaneous tract over or through the tubular member from the incision site to a target area within the presacral space. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
