    摘要： Described herein are methods and systems for precisely placing and/or manipulating devices within the body by first positioning a guidewire or pullwire through the body from a first location, around a curved pathway, and out of the body through a second location, so that the distal and proximal ends of the guidewire extend from the body, then pulling a device into position using the guidewire. The device to be positioned within the body is coupled to the proximal end of the guidewire, and the device is pulled into the body by pulling on the distal end of the guidewire that extends from the body. The device may be bimanually manipulated by pulling the guidewire distally, and an attachment to the device that extends proximally, allowing control of both the proximal and the distal ends. In this manner devices (and particularly implants such as innerspinous distracters, stimulating leads, and disc slings) may be positioned and/or manipulated within the body. Devices to modify tissue may also be positioned or manipulated so that a target tissue within the body is modified.

    摘要： A method and system for guiding at least a portion of a surgical device to a desired position between two tissues in a patient's body involves coupling a guidewire to the device and pulling the distal end of the guidewire to guide at least a portion of the surgical device to a desired position between the two tissues. The surgical device generally includes one or more guidewire coupling members and may comprise a tissue access device. A system may include a guidewire and a surgical device. In some embodiments, a guidewire, a tissue access device, and one or more additional devices to use with the access device may be provided. Methods, devices and systems may be used in open, less-invasive or percutaneous surgical procedures, in various embodiments.

    摘要： Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.
