    摘要： Apparatuses and methods for accessing a tissue and expanding an apparatus within the tissue are disclosed. In one embodiment, an apparatus includes a first expandable member and a second expandable member disposed within the first expandable member. The first expandable member is configured to disrupt a body when in an expanded configuration and rotated relative to the body. The second expandable member is configured to block at least a portion of disrupted portions of the body from being disposed within the first expandable member. In some embodiments, the first expandable member is coupled to a sheath. The first expandable member is configured to be inserted at least partially into the body while disposed within a lumen of the sheath. The sheath is configured to be moved proximally while at least partially inserted into the body such that the first expandable member is moved from its collapsed to its expanded configuration.

    摘要： In one embodiment, an apparatus includes an elongate body having a collapsed configuration and an expanded configuration. The elongate body has a cutting portion at a distal portion of the elongate body, and the cutting portion defines an opening in the elongate body. The distal portion of the elongate body is configured to be inserted into a nucleus of an intervertebral disc when the elongate body is in the collapsed configuration. The cutting portion of the elongate body is configured to disrupt at least a portion of tissue within the nucleus of the intervertebral disc when the elongate body is in the expanded configuration. The elongate body is configured to capture the portion of tissue within the opening of the elongate body when the elongate body is moved from the expanded configuration to the collapsed configuration while disposed within the nucleus of the intervertebral disc.

    摘要： A bone fusion device, system, kit, and/or method can include an elongated structure including at least two anchor portions and at least one deformable segment connected on each end to one of the at least two anchor portions. Each deformable segment can include a plurality of spaced apart deformable members deformable from an unexpanded configuration to an expanded configuration. The bone fusion device may be implanted between two bone structures in the unexpanded configuration utilizing a minimally invasive surgical procedure. The deformable members can be compressed along a longitudinal axis of the device to deform the deformable members to the expanded configuration into contact with the two bone structures. A bone growth promoting material can be placed in the anchor portion lumen and in the interior of each deformable segment to promote bone in-growth between the bone structures.

    摘要： The present invention is directed to a radially expansive device for providing access into a patient's body, kits that contain the radially expansive device, as well as methods for providing minimally invasive access into a patient's body. The radially expansive device may be used in conjunction with a balloon, bladder, or other expansive device, which can be used to expand the radially expansive device and allow access to the surgical site.
