Tissue modification barrier devices and methods
First Claim
1. A method for preventing unwanted damage to tissue in a spine of a patient during a tissue modification procedure, the method comprising:
- advancing a distal portion of a delivery device into an epidural space of the patient'"'"'s spine;
exposing at least a portion of at least one barrier member out of the distal portion of the delivery device, wherein at least a portion of the barrier member is changeable from a collapsed configuration in the delivery device to an expanded configuration outside the delivery device;
positioning at least part of the exposed barrier member between target tissue and non-target tissue in the spine; and
performing at least one tissue modification procedure on the target tissue, using at least one tissue modification device, wherein at least part of the barrier member is disposed between the at least one tissue modification device and the non-target tissue to prevent unwanted damage to the non-target tissue.

Abstract
A method for preventing unwanted damage to tissue in a spine of a patient during a tissue modification procedure may involve: advancing at least a distal portion of at least one barrier member over at least one guide member into an epidural space of the patient'"'"'s spine; positioning at least an expanded portion of the barrier member between target tissue and non-target tissue; and performing at least one tissue modification procedure on the target tissue, using at least one tissue modification device. Generally, at least part of the barrier member may be disposed between the tissue modification device and the non-target tissue to prevent unwanted damage to the non-target tissue. In various embodiments, at least part of a barrier member may be advanced through a sheath- or catheter-like delivery device and may either automatically expand or be expandable from a collapsed configuration to an expanded configuration.

37. A method for preventing unwanted damage to tissue of a patient during a tissue modification procedure, the method comprising:
-
advancing at least a distal portion of a delivery device into the patient and to a position between or adjacent target tissue and non-target tissue;
advancing at least a distal portion of at least one barrier member over at least one guide member to a position between or adjacent target tissue and non-target tissue in the patient;

38. A barrier device for preventing unwanted damage to tissue of a patient during a tissue modification procedure, the device comprising:
-
at least one shape changing portion changeable from a collapsed configuration, to facilitate passage into the patient, to an expanded configuration, to facilitate protection of non-target tissue;
at least one elongate portion extending beyond the shape changing portion, the elongate portion having a low profile to facilitate passage of the barrier device into the patient and a length sufficient to extend from an opening on the patient'"'"'s skin to an area at or near target and non-target tissues; and
at least one guide feature extending along at least a portion of the barrier to allow the barrier to be passed into the patient over at least one guide member, wherein the barrier device has an overall length sufficient to pass from a first opening on the patient'"'"'s skin and between the target and non-target tissues. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
