摘要: A method for removing at least part of a brain tumor may first involve contacting a forward-facing tissue cutter disposed at the distal end of a tissue removal device with the brain tumor. The tissue removal device may include a shaft having a diameter no greater than about 10 mm, and in some embodiments the tissue cutter does not extend laterally beyond the diameter of the shaft. The method may next involve cutting tissue from the brain tumor, using the tissue cutter. The method may then involve moving the cut tissue through a channel of the shaft in a direction from the distal end of the tissue removal device toward a proximal end of the device.

摘要: A medical device for removing or manipulating tissue of a subject is provided with a distal housing having an end effector, and an elongate member configured to introduce the distal housing to a target tissue site of the subject. The elongate member may have proximal and distal portions interconnected by a joint mechanism that is configured to allow the two portions to articulate relative to one another. In some embodiments, the joint mechanism includes one or more nested crown gear(s) configured to drive associated spur gear(s) to accomplish the articulation. In some embodiments, the end effector is a powered scissors device.

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: Described herein are devices and systems for accessing a spine and particularly the epidural region of the spine and methods of using these systems and devices to access the spine or regions of the spine. In particular, cannulas that may be anchored to the ligamentum flavum or the periosteum are described. Ligamentum flavum access tools are also described. These tools may be used with (or without) an anchoring cannula to penetrate the ligamentum flavum and provide access to the epidural space without risk of injury to other structures within the epidural space. The devices, methods and systems described herein are particularly useful in minimally invasive surgical (MIS) uses. The devices, methods and systems described herein may be used for performing spinal decompressions and other spinal procedures.

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: Described herein are elongate device 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 (e.g., chamber, bag, or the like) may be used to collect the cut or modified tissue. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.

摘要: Described herein are elongate device 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 (e.g., chamber, bag, or the like) may be used to collect the cut or modified tissue. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.
