Patent ID: 8574256

Claim:
A method of forming a surgical opening from a bladder through an abdominal wall, comprising: providing an elongate tubular body having a proximal portion and a distal portion extending along a linear axis; inserting the distal portion through a urethra and into the bladder to a position at which the surgical opening is formed; providing an elongate arm having a first end and a second end having an indicator establishing an axis; operably attaching the first end of the arm with the proximal portion of the tubular body and positioning the second end of the arm to locate the indicator externally over the abdominal wall with the axis of the indicator arranged in coaxial alignment with the linear axis of the distal portion of the tubular body; puncturing the surgical opening by extending an advancement member out of the distal portion of the tubular body and along the linear axis of the distal portion of the tubular body through the abdominal wall to the indicator; and indicating with the indicator the position of the linear axis on the external abdominal wall by maintaining the axis of the indicator in coaxial alignment with the linear axis of the distal portion of the tubular body while the advancement member extends from the tubular body through the abdominal wall to puncture the surgical opening.
