Abstract

Apparatus for creating an anatomic space in tissue in a body including an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A blunt tip is secured to the distal extremity of the tunneling shaft. A balloon assembly is provided. The balloon assembly is removably secured to the tunneling shaft. The balloon assembly includes a deflated collapsed balloon. A sheath encloses the balloon and is carried by the tunneling shaft. The sheath has a weakened region extending longitudinally thereof permitting the sheath to be removed to release the balloon.

Claims

1. A method for creating a working space comprising:

providing a surgical device including a housing and a cannula extending therefrom;

inserting the surgical device through an incision in a patient'"'"'s skin;

inserting a tunneling rod guide into the cannula of the surgical device, the tunneling rod guide including;

an obturator;

a guide tube;

and a guide collar including;

an end collar disposed at a distal end of the guide collar and a first collar disposed on a proximal end of the guide collar, the guide collar transitionable between a first state defined by engagement of the proximal end of the guide collar with a first region of the first collar defining a first diameter and a second state defined by engagement of the proximal end of the guide collar with a second region of the first collar defining a second diameter different from the first diameter;

moving the obturator and the guide tube relative to each other such that the guide collar expands and frictionally engages an inner surface of the cannula;

advancing the obturator distally such that a blunt tip of the obturator separates layers of tissue;

removing the tunneling rod guide;

removing the surgical device from the incision.

2. The method of claim 1, further comprising:

inserting a dissection balloon through the cannula; and

inflating the dissection balloon to create the working space.

3. The method of claim 1, wherein the surgical device includes an anchoring balloon.

4. The method of claim 1, wherein the guide tube is disposed around the obturator rod.

5. The method of claim 1, wherein relative movement between the obturator and the tunneling rod guide transitions the guide collar from the first state to the second state such that the guide collar is longitudinally repositionable within the cannula when the guide collar is in the second state.
