摘要： A blade assembly for use with a surgical saw. The blade assembly may comprise a static guide bar, a blade and a drive member, that when actuated, oscillates the blade. The blade may further comprise teeth that extend distally from the static guide bar, the teeth adapted to form a kerf in tissue against which the teeth are pressed. The static guide bar may be dimensioned to fit into the kerf formed in the tissue cut by the teeth. The static guide bar may comprise a thickness dependent on a length of the static guide bar. The blade assembly may be configured such that blade may be the only oscillating component of the blade assembly to provide a generally constant mass moment of inertia irrespective of the mass and/or length of the static guide bar.

摘要： Described herein are devices, systems and methods for treating target tissue in a patient's spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.

摘要： Described herein are elongate devices for modifying tissue having a plurality of flexibly connected rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element may be used to collect the cut or modified tissue.

摘要： The present invention is a method for performing a percutaneous laminoplasty that includes entering a first introducer needle introducing a first tool wire into an epidural space above a selected lamina, entering a first catcher exit needle that that is caught with the first introducer needle and pulled through a patient body and entering a second introducer needle introducing a second tool wire into the epidural space below the selected lamina. The method also includes entering a second catcher exit needle that is caught within the epidural space and pulled through the patient body, moving the caught first introducer needle and the first catcher exit needle back and forth to cut the lamina and moving the caught second introducer needle and the second catcher exit needle back and forth to cut the lamina. There is also a method for performing a percutaneous foraminoplasty.

摘要： A surgical sagittal saw blade assembly and cutting guide for use with the blade assembly. The blade assembly includes a static bar from which a moving blade head protrudes. The blade head is reciprocated by a drive link internal to the bar. The cutting guide has a body that is positioned adjacent where the blade is to be used to cut tissue. The cutting guide has an outer surface over which the blade assembly is positioned. The cutting guide has a constraining feature. The constraining feature holds the blade bar to the body of the guide so the blade assembly can move over the body while being constrained from movement above the outer surface of the body. The constraining feature is mounted to the body of the cutting guide so as to be able to move while constraining guide retains the blade bar.

摘要： A method and apparatus for transecting soft tissue, such as a ligament, and more particularly, the transverse carpal ligament. A pair of hollow introducer needles can be used to rout a thread-like, smooth and non-abrasive cutting element around tissue, such as a soft tissue, to enable a transection of the soft tissue using minimally invasive techniques. The cutting element is routed into position about the target soft tissue such that the cutting element both enters and exits the body from the same side of the soft tissue. The smooth and non-abrasive exterior surface of the cutting element serves to provide a kerf-less cut.

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. 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 a 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. Guidewire exchange systems, devices and methods are also described. A guidewire may be exchanged between different surgical devices and may be releaseably or permanently coupled.

摘要： 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 includes a profile having a width that is substantially greater than a height.
