    摘要： Partially encapsulated stents are made using strips and bands of covering material. In one embodiment ringed stents are placed over an inner ePTFE tube (e.g., supported on a mandrel) and are covered by a series of longitudinal strips. A series of spaced apart ePTFE circumferential bands can then be placed over the top of the longitudinal strips and ringed stents; alternatively bands alone or strips alone may be employed. All of the components of the structure are then laminated to the inner ePTFE tube to capture the stent. By selecting the size and position of the ePTFE bands, it is possible to leave critical parts of the stent unencapsulated to facilitate flexibility and expansion. The longitudinal strips can be woven about the stent and later laminated into position to provide an anti-compression function as well as overall structural stability. Although a single stent can be used, these approaches lend themselves to use of a plurality of individual ring stents spaced apart along the inner ePTFE tube.

    摘要： Partially encapsulated stents are made using gaps cut into ePTFE covering material. Ring stents are placed over an inner ePTFE tube (e.g., supported on a mandrel) and are covered by a “lacey” graft sleeve, which is constructed by cutting apertures into an ePTFE tube so that a series of circumferential and longitudinal strips is created. This “lacey” sleeve is then laminated to the inner ePTFE tube to capture the stents. By selecting the size and position of the apertures in the ePTFE covering, it is possible to leave critical parts of the stent unencapsulated to facilitate flexibility and expansion. Alternatively, the gaps can consist of slits cut into the ePTFE covering material. These slits can be cut in any direction including longitudinally, radially, or diagonally. In addition, the slits can be spaced at varying intervals around the covering material to maximize flexibility and expandability. Although a single stent can be used, these approaches lend themselves to use of a plurality of individual ring stents spaced apart along the inner ePTFE tube.

    摘要： In one embodiment, an apparatus includes an elongate body and an expandable member coupled to the elongate body. The expandable member is configured to be disposed within an interior of a vertebral body having a first portion that includes cancellous bone and having a second portion that includes sclerotic bone distinct from an endplate of the vertebral body. The expandable member is configured to exert a first pressure on the first portion of the vertebral body and a second pressure different from the first pressure on the second portion of the vertebral body. The second pressure is sufficient to move the second portion of the vertebral body in a direction away from the expandable member when the expandable member is expanded within the interior of the vertebral body.

    摘要： Tissue distractor devices, systems, and methods for soft tissue expansion in order to create a space between the tissue to improve visualization and for increased working space during surgery are disclosed. One method for separating soft tissues for cannula access to a treatment site within a patient body comprises providing a catheter having a tissue distractor on a distal end thereof and positioning the catheter between the soft tissues near the treatment site. Once properly positioned, the tissue distractor is expanded so as to separate the soft tissues. The tissue distractor is then elongated by mechanical actuation so as to provide cannula access to the treatment site. The cannula forms a working channel for surgical procedures, particularly minimally invasive surgical procedures.
