摘要:
The present invention is an improved separating device for providing the malabsorptive component of a minimally invasive weight reduction system. This device may be a sleeve, liner, or tubular sheath that alters absorption of compositions through walls of hollow organs (stomach, intestines). The improvement involves better long-term retention through the ability of the device to engage with the interserosal fibrotic tissue formed in an intussusception. The separating device may be a distal extension of a retaining member that is directly engaged with and retained by intussuscepted tissue. Intussusception shrinks a hollow organ to provide a volume reducing restrictive component of a weight reduction system. Securing the separating device to an intussusception avoids retention problems of reference art devices as interserosal fibrosis helps secure the device. Also provided are an apparatus for retaining the device, a device and method for delivering the separating device, and a method for removing it.

摘要:
Prosthetic intervertebral discs and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The prosthetic discs described herein include one-piece, two-piece, three-piece, and four-piece structures. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components of the discs. The interface mechanism between the endplates and the core members of several embodiments of the described prosthetic discs enables a very easy surgical operation for implantation.
摘要:
A percutaneous path is established into a selected bone, e.g., a vertebral body, having an interior volume occupied, at least in part, by cancellous bone. A first bone filling material is conveyed through the percutaneous path into a region of the cancellous bone. A second bone filling material is conveyed through the percutaneous path into the region. The second bone filling material is different than the first bone filling material.
摘要:
Cancellous bone is accessed through a subcutaneous access path in soft tissue. A cavity is formed in cancellous bone by a cavity forming tool that is advanced through the subcutaneous access path into cancellous bone and manipulated to form the cavity. A measured volume of bone filling material is delivered into the cavity through the subcutaneous access path by a nozzle having an interior bore defining an interior volume sized for containing bone filling material, which is advanced through the subcutaneous access path. A nested instrument is formed while clearing residual bone filling material from the interior bore by an auxiliary tool that can be manipulated independently of the nozzle, which is advanced through the interior bore of the nozzle.

摘要:
A cavity creating device having a cavity creating axis is introduced through a percutaneous access path into a cancellous bone volume, e.g., within a vertebral body. The cavity creating device is manipulated to form a cavity in the cancellous bone volume. The manipulation includes deflecting the cavity creating device along the cavity creating axis relative to the axis of the access path. A material, such as bone cement, can be conveyed into the cavity.
摘要:
A cannula instrument is deployed in soft tissue to form a percutaneous access path to bone. A guide pin instrument is sized and configured for passage through a bore of the cannula instrument. A handle separate from the cannula instrument and the guide pin instrument includes an attachment component configured to selectively engage or disengage the handle attachment site of the cannula instrument to aid in advancement of the cannula instrument through soft tissue and form the percutaneous access path. A passageway in the handle accommodates passage of the guide pin instrument through the handle to accommodate sliding the handle over and relative to the guide pin instrument when selectively engaging or disengaging the attachment component and the handle attachment site. A therapeutic instrument is deployed through the percutaneous access path.
