Tissue modification devices and methods |
摘要 |
Devices and methods for cutting tissue in a patient. In some embodiments, a bimanually controlled device may include a tissue modification region; one or more (e.g., two) flexible elongate length of cable that extend proximally to distally, a tissue modification region along a portion of the length of cable; and a guidewire coupler at the distal end of the device for attaching the distal end of the tissue modification device to the proximal end of a guidewire. Method of using these devices (including devices having two or more parallel length of cutting regions) to cut tissue (e.g., spinal lamina) are also described. |

1. A bimanually controlled tissue modification device for cutting at least one of bone and tissue in a patient, the device comprising:
an elongate spacer having spaced-apart opposing edge portions extend substantially parallel to each other and a central portion extending between the opposing edge portions, wherein the central portion has a first side and a second side, wherein each one of the edge portions includes a wire retaining structure extending at least partially along a length of the elongate spacer at the first side thereof, and wherein the central portion has a concave cross-sectional curvature with respect to the first side thereof along at least a portion of the length thereof; two elongate bodies each having a tissue modification region, wherein each one of the elongate bodies is secured to a respective one of the opposing edge portions of the spacer by the wire retaining structure thereof such that the elongate bodies extend in side-by-side spaced apart relationship with respect to each other, wherein at least a portion of the tissue modification region of each one of the elongate bodies extends along the length of the central portion having the concave cross-sectional curvature, wherein the two elongate bodies each comprises a flexible elongate length of wire extending proximally to distally, wherein the tissue modification region includes at least a portion of the flexible elongate length of wire, and wherein the flexible elongate length of wire comprises a plurality of cutting members each at a respective fixed location with respect to the flexible elongate length of wire of each one of the elongate bodies, wherein the cutting members are defined by a spiral or helical cutting edge and wherein the cutting members and the flexible elongate length of wire are integrally formed; and a guidewire coupler at a distal end region of the flexible elongate length of wire of at least one of the elongate bodies. |
