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.

Medical device with dual expansion mechanism

A surgical access device can include a plurality of retractor members that together define a lumen having a first cross-sectional dimension. Each of the plurality of retractor members can be moved radially outward to at least a second cross-sectional dimension to create a surgical access passage. The surgical access device, systems and kits comprising the surgical access device, and methods of using the surgical access device can include a mechanism for inserting an elongate member from exterior the body to the surgical site, a mechanism for moving the retractor members radially outward, a mechanism for guiding the radially outward movement of the retractor members, a mechanism for securing each of the retractor members in a range of positions, and a mechanism for illuminating the surgical site. Variations of the devices, systems, kits, and methods are useful for creating and maintaining a surgical access passage for performing minimally invasive surgery.

Surgical access device, system, and methods of use

Several embodiments of cutting tips for tools for creating voids in interior body regions are provided. The cutting tips provide for rotational and translational cutting. An actuator mechanism for deploying a cutting tip converts the rotational movement of a wheel into translational movement of a plunger rod. The actuator mechanism provides positive cutting action as the cutting tip is moved from a first, non-deployed position to a second, deployed position and from the second, deployed position to the first, non-deployed position. Methods of creating a void in bone provide one or more mechanical cutting tools that may be used in combination with one or more expandable void-creating structures to form a void of a desired size and configuration.
