12 . A method of percutaneously treating a target site within the body, the method comprising: percutaneously accessing an area of tissue adjacent the target site with an access device having a scope; expanding a material from the a distal portion of the access device wherein a space is created adjacent the distal portion; visualizing the space with the scope; and advancing an instrument to within the space to treat the target site.
Claim 14
Dependent Claim
73 words
12 . A method of percutaneously treating a target site within the body, the method comprising: percutaneously accessing an area of tissue adjacent the target site with an access device having a scope; expanding a material from the a distal portion of the access device wherein a space is created adjacent the distal portion; visualizing the space with the scope; and advancing an instrument to within the space to treat the target site.
Claim 15
Dependent Claim
14 words
13 . The method of claim 12 , wherein the material defines a balloon.
Claim 16
Dependent Claim
28 words
14 . The method of claim 12 , wherein the balloon defines a central opening when expanded and the method further comprises advancing the scope through the opening.
Claim 17
Dependent Claim
18 words
15 . The method of claim 14 , wherein the balloon is expanded substantially laterally of the scope.
Claim 18
Dependent Claim
23 words
16 . The method of claim 14 , further comprising expanding two or more balloons from a distal portion of the access device.
Claim 19
Dependent Claim
23 words
17 . The method of claim 16 , further comprising stabilizing the access device within the body wherein using at least one balloon.
