Percutaneous access and visualization of the spine
First Claim
Patent Images
1. A method of percutaneously accessing a target site within the body, the method comprising:
- introducing into the body an access device comprising a tissue manipulation member and having direct visualization capability, wherein the tissue manipulation member is deployable from a distal portion of the access device;
deploying the tissue manipulation member thereby displacing tissue adjacent the distal end of the access device to create a space within the tissue between the distal end and the target site; and
directly visualizing the space.

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 wire 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. 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 plurality of bands 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. - View Dependent Claims (22, 23, 24, 25, 26)

27. A method of percutaneously accessing a target site at the spine, the method comprising:
-
introducing into the body an access device comprising a tissue manipulation member and having direct visualization capability, wherein the tissue manipulation member is deployable from a distal portion of the access device;
deploying the tissue manipulation member into the tissue; and
proximally pulling the tissue manipulation member thereby stabilizing the access device.

28. A system for accessing a target site within the body, the system comprising:
-
a cannula having at least one lumen;
a scope deliverable through the at least one cannula lumen; and
at least one strut deployable from a distal portion of the cannula, where deployment of the at least one strut creates a space within tissue adjacent the distal portion of the cannula wherein the space facilitates visualization by the scope. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A system for accessing a target site within the body, the system comprising:
-
a cannula having at least one lumen;
a scope deliverable through the at least one cannula lumen; and
a wire deployable from a distal portion of the cannula, wherein deployment of the wire creates a space within tissue adjacent the distal portion of the cannula wherein the space facilitates visualization by the scope. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
