Articulating Tissue Cutting Device
First Claim
1. A device for cutting ligament and/or bone tissue in a lateral recess and/or an intervertebral foramen of a spine of a patient to treat spinal stenosis, the device comprising:
- an elongate shaft having a rigid proximal portion and a distal portion articulatable relative to the proximal portion;
a handle coupled with the proximal portion of the shaft;
a tissue cutter disposed on one side of the distal portion of the shaft;
a first actuator coupling the handle with the tissue cutter for activating the tissue cutter to cut tissue; and
a second actuator coupling the handle with the distal portion for articulating the distal portion relative to the proximal portion.

Abstract
A device for cutting ligament and/or bone tissue in a lateral recess and/or an intervertebral foramen of a spine of a patient to treat spinal stenosis may include: an elongate shaft having a rigid proximal portion and a distal portion articulatable relative to the proximal portion; a handle coupled with the proximal portion of the shaft; a tissue cutter disposed on one side of the distal portion of the shaft; a first actuator coupling the handle with the tissue cutter for activating the tissue cutter to cut tissue; and a second actuator coupling the handle with the distal portion for articulating the distal portion relative to the proximal portion. In some embodiments, the distal portion of the shaft may be configured to pass at least partway into an intervertebral foramen of the patient'"'"'s spine.

22. A method for cutting ligament and/or bone tissue in a lateral recess and/or an intervertebral foramen of a spine of a patient to treat spinal stenosis, the method comprising:
-
advancing a distal portion of a tissue cutting device into an epidural space of the patient'"'"'s spine; articulating the distal portion relative to a proximal portion of the device; advancing the distal portion at least partway into an intervertebral foramen of the spine; urging a tissue cutter disposed on one side of the distal portion of the device against at least one of ligament or bone tissue in at least one of the lateral recess or the intervertebral foramen; and activating the tissue cutter to cut at least one of the ligament or bone tissue. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
