Abstract: An apparatus for treating tissue, comprising a sheath defining a lumen sized and shaped to receive a treatment device therein, a guide member coupled to the sheath and extending a predetermined distance substantially parallel to a longitudinal axis of the sheath, and a stabilizer element for engaging an anchoring device coupled to tissue to stabilize the sheath and the treatment device, the stabilizing element being movably coupled to the guide member for movement therealong substantially parallel to the longitudinal axis of the sheath wherein, when in a proximal-most position, the stabilizer element is located proximally of a proximal end of the guide member.

Abstract: There is provided a virtual object rendering system comprising a camera, at least one sensor for sensing perspective data corresponding to a camera perspective, a communication interface configured to send the perspective data to a virtual object rendering computer, and the virtual object rendering computer having one or more virtual objects, the virtual object rendering computer configured to determine the camera perspective from the perspective data, and to perform the virtual object rendering by redrawing the one or more virtual objects to align the one or more virtual objects with the camera perspective. The virtual object rendering computer may be further configured to produce a merged image of the one or more redrawn virtual objects and a camera image received from the camera.
