Abstract
Abstract The invention provides a driver and methods for advancing needles, cannulas, and other medical devices through the pubic bone. The driver may be used in connection with a driver frame assembly for proper positioning and stabilization of the driver, and with other devices for creating a cavity in the urethral floor and for positioning medical devices therein. The invention also provides simple connections for attaching a suture to a device within the cavity in the urethral floor or in the vagina, and also for attaching sutures to the pubic bone.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
213 words
A dilator for creating a cavity, comprising: an insertion spreader comprising a first elongate semi-cylindrical spreader guide and a second elongated semi-cylindrical spreader guide, said first and second guides each having a distal end and a proximal end, said first and second guides being sharpened at said distal ends, said first guide being parallel to said second guide, said guides of said insertion spreader being movable between a closed position and an open position; a first and a second handle, each of said handles having a first end and a second end, wherein said first end of said first handle is attached to said first guide, said first end of said second handle is attached to said second guide, wherein the longitudinal axis of said first and second handles is substantially perpendicular to the longitudinal axis of said first and second guides, respectively, and said second end of each of said handles is adapted to allow a person to grasp and manipulate said dilator; and a pivot intermediate said first end and said second end of each of said handles, said handles being movably connected at said pivot, whereby movement of said handles about said pivot causes a displacement of said guides to move said guides between said closed and said open positions.
Claim 2
Dependent Claim
213 words
A dilator for creating a cavity, comprising: an insertion spreader comprising a first elongate semi-cylindrical spreader guide and a second elongated semi-cylindrical spreader guide, said first and second guides each having a distal end and a proximal end, said first and second guides being sharpened at said distal ends, said first guide being parallel to said second guide, said guides of said insertion spreader being movable between a closed position and an open position; a first and a second handle, each of said handles having a first end and a second end, wherein said first end of said first handle is attached to said first guide, said first end of said second handle is attached to said second guide, wherein the longitudinal axis of said first and second handles is substantially perpendicular to the longitudinal axis of said first and second guides, respectively, and said second end of each of said handles is adapted to allow a person to grasp and manipulate said dilator; and a pivot intermediate said first end and said second end of each of said handles, said handles being movably connected at said pivot, whereby movement of said handles about said pivot causes a displacement of said guides to move said guides between said closed and said open positions.
Claim 3
Dependent Claim
19 words
The dilator of claim 1 further comprising a ratcheting lock for maintaining said insertion spreader in a fixed position.
Claim 4
Dependent Claim
21 words
