Devices and methods for tissue access
First Claim
1. A surgical tissue removal device comprising:
- a flexible elongate body that is adapted to conform with a target anatomy, the body having a working surface for separating and removing impinging tissue, the working surface defined by at least one blade edge, where the flexible elongate body is a thin, flat, ribbon shaped flexible body that comprises a profile having a width that is substantially greater than a height;
a guidewire connector at a distal end region of the flexible elongate body configured to removably connect to an end of a guidewire so that the guidewire and the flexible elongate body can be pulled distally, wherein the at least one blade edge is a v-shaped blade edge; and
wherein a portion of the flexible elongate body removed from the working surface includes a lubricious layer not on the working surface for removing tissue.

Abstract
Methods and apparatus are provided for selective surgical removal of tissue, e.g., for enlargement of diseased spinal structures, such as impinged lateral recesses and pathologically narrowed neural foramen. In some embodiments, a surgical tissue removal device includes a flexible elongate body that is adapted to conform with the target anatomy and a guidewire connector at the distal end region of the flexible elongate body configured to removably connect to the end of a guidewire so that the guidewire and flexible elongate body can be pulled distally. The body may have at least one blade edge, and the flexible elongate body may be a thin, flat, ribbon shaped flexible body that comprises a profile having a width that is substantially greater than a height.

7. A surgical tissue removal device, comprising:
-
a flexible elongate body that is adapted to conform with a target anatomy, the body having a working surface for separating and removing impinging tissue, the working surface defined by at least one blade edge extending from one surface of the flexible elongate body, where the flexible elongate body is a thin, flat, ribbon shaped flexible body that further comprises a profile having a width that is substantially greater than a height; a guidewire connector on the flexible elongate body configured to connect to an end of a guidewire so that the end of the guidewire connects into the guidewire connector at a distal end region of the flexible elongate body so that the guidewire and the flexible elongate body can be pulled distally to draw the at least one blade edge distally across the target anatomy, wherein the at least one blade edge is a v-shaped blade edge; and wherein a portion of the flexible elongate body removed from the working surface includes a lubricious layer not on the working surface for removing tissue. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
