1. A cannula assembly comprising:
- a tubular element forming a first lumen, the tubular element having a proximal end and a distal end adapted to be inserted into a body cavity;
a subassembly releasably attached to the tubular element, the subassembly comprising a deployable element disposed proximate the distal end of the tubular element, wherein the deployable element is adapted for movement between a closed position which substantially obstructs the first lumen and an open position which does not substantially obstruct the first lumen, wherein the deployable element remains coupled to the tubular element in the closed and open positions, and wherein at least one of the subassembly and the tubular element comprises at least two multi-axis accelerometers;
an electronic component coupled to the deployable element, wherein the electronic component comprises at least one imaging device and at least one illumination source, and wherein the subassembly, including the deployable element and the electronic component, are releasable from the tubular element; and
an ancillary electronics module comprising a processor adapted to generate images with a selectable horizon based on inputs from the multi-axis accelerometers and the imaging device, wherein the ancillary electronics module is adapted to determine an angle of deployment of the deployable element with respect to the tubular element based upon inputs from the multi-axis accelerometers.

Abstract
A cannula assembly includes a tubular element forming a lumen, a deployable element of a subassembly, and an electronic component mounted to the deployable element. The tubular element has a proximal end and a distal end adapted to be inserted into a body cavity. The deployable element is coupled through the subassembly to the tubular element, and is adapted to transition between a closed position and an open position. The electronic component has at least one imaging device and at least one illumination source. The subassembly, including the deployable element and the electronic component, are releasable from the tubular element.

19. A method of using a cannula assembly comprising:
-
inserting a tubular element forming a first lumen and a subassembly releasably attached to the tubular element into a body cavity, wherein the tubular element has a proximal end and a distal end; actuating a substantially cylindrical deployable element of the subassembly from a closed position substantially obstructing the lumen to an open position, wherein an electronic component mounted to the deployable element comprises at least one imaging device for providing a forward view during insertion; receiving inputs from at least two multi-axis accelerometers; processing the inputs with an ancillary electronics module to determine an angle of deployment of the deployable element with respect to the tubular element; inserting an instrument into the lumen for performing a surgical procedure; and removing the tubular element and the subassembly from the body cavity. - View Dependent Claims (20, 21, 22, 23)
