    摘要: In the context of endoscopic electrosurgery, there is a need for a sufficiently robust, rigid, and preferably aspirating electrosurgical device that may be repeatedly flexed in the field to allow access to a wide array of remote tissues using a single device and, more preferably, during a single minimally invasive procedure. The present invention addresses this significant need by providing the distal portion of the elongate tubular member of an electrosurgical device with a bend region having a non-uniform flexural strength along its length, such that one may bend the tubular member at said bend region not only to an initial small radius bend, but subsequently rebend the distal portion to other angles as needed, with all bends occurring in the same distal region. A number of different mechanisms for reducing the flexural strength in the bend region are disclosed herein, including, for example, notching the tube in the bend region, annealing the tube in the bend region, reducing the wall thickness in the bend region, utilizing a material having lower flexular and/or yield strength to form the bend region, utilizing a small diameter elongate conductive element having negligible rigidity, such as a wire, and combinations thereof.

    摘要: Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the placement of small diameter knotless anchors. For example, the implant placement system may include a cannulated tensioning device having disposed therein an elongate member of a suitably elastic metallic or polymeric material, such as nitinol, that includes at its distal end a loop of material suitable for suture retention. The implant placement system may further include high tensile strength knotless anchors provided with internal drive features that coordinate with torque-transmitting features unique to the driver devices of the present invention.

    摘要: Described herein are specialized methods and systems that may be utilized to secure a soft tissue graft to a boney surface. The methods and systems of the present invention facilitate the efficient and minimally invasive formation of sockets and/or tunnels in boney surfaces that may then serve as a site for graft placement by aperture and/or suspensory fixation means. The present invention has particular applicability to the surgical repair and reconstruction of torn or ruptured ligaments of the leg, such as anterior and posterior cruciate ligaments.

    摘要: Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation. To that end, embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein.
