Abstract
Abstract A surgical dissector and method for facilitating fiberoptic viewing when developing a minimally invasive accessway to a surgical objective in the interior of the body. The dissector or guide is used to dissect tissues along an anatomic plane under direct fiberoptic vision. A balloon is provided to further dissect and retract tissue along the dissected accessway to provide an adequate depth of field for fiberoptic viewing through transparent walls of the balloon. The dissection allows a surgeon safely to make additional incisions into the region of the fiberoptic viewing space and to perform surgical procedures under fiberoptic vision by manipulating an accessory instrument on the exterior surface of the inflated balloon that is disposed within the dissected space.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
A method for making at least one outward incision in a body for cannula placement using an elongate guide member, comprising the steps of: introducing a distal extremity of the guide member through a first incision into the interior of the body at a first region; advancing the distal extremity of the guide member within the interior of the body to a second region remote from the first region; and advancing the distal extremity of the guide member outwardly from the interior of the body in the second region until the distal end of the guide member projects outwardly from the skin of the body, thereby making the at least one outward incision in the second region.
Claim 2
Independent Claim
117 words
A method for making at least one outward incision in a body for cannula placement using an elongate guide member, comprising the steps of: introducing a distal extremity of the guide member through a first incision into the interior of the body at a first region; advancing the distal extremity of the guide member within the interior of the body to a second region remote from the first region; and advancing the distal extremity of the guide member outwardly from the interior of the body in the second region until the distal end of the guide member projects outwardly from the skin of the body, thereby making the at least one outward incision in the second region.
Claim 3
Dependent Claim
43 words
The method of claim 1, further comprising the step of holding down the skin in the second region with a hold down device to permit the distal extremity of the guide member to advance outwardly from the skin through the hold down device.
Claim 4
Dependent Claim
59 words
The method of claim 1, further comprising the step of placing a cannula over the distal end of the guide member that projects outwardly from the skin in the second region and advancing the cannula inwardly toward the interior of the body over the guide member until the distal end of the cannula is disposed within the additional incision.
Claim 5
Dependent Claim
28 words
The method of claim 3, further comprising the step of withdrawing the distal end of the guide member from the cannula that is disposed within the additional incision.
Claim 6
Dependent Claim
21 words
The method of claim 3, wherein said advancing to a second region includes advancing the distal extremity between overlapping muscle tissue.
Claim 7
Dependent Claim
35 words
The method of claim 1, further comprising the step of viewing through the guide member the advancement of the guide member in the interior of the body from the first region to the second region.
Claim 8
Dependent Claim
33 words
The method of claim 1, further comprising the step of creating an anatomic space between the first region and second region by blunt dissection of tissue between the first region and second region.
Claim 9
Dependent Claim
24 words
The method of claim 7, further comprising the step of insufflating the space that was bluntly dissected between the first region and second region.
Claim 10
Dependent Claim
23 words
The method of claim 1, further comprising making said first incision in a first region of the body prior to said introducing step.
Claim 11
Dependent Claim
29 words
The method of claim 9, wherein the first incision making step comprises penetrating the distal end of the guide member through the skin into the interior of the body.
