In invertebrate biology, an appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body (in vertebrate biology, an example would be a vertebrate's limbs). An appendage is any of the homologous body parts that may extend from a body segment. These include antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, walking legs (pereiopods), swimming legs (pleopods), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages.

Left atrial appendage exclusion device
A device for excluding the inner cavity of the left internal appendage (LAA) from the interior of the left atrium LA may include a pair of compression members spaced apart and defining a closed periphery. The closed periphery has a variable-sized opening therein that can be enlarged to surround the LAA and then closed to compress and exclude the LAA. The closed periphery may be generally rectangular or lenticular, and may be a solid, contiguous periphery or separable at a closure. Inner protrusions or ribs may be provided on the compression members to help anchor the exclusion device in place. Needles may also be provided to pierce the LAA tissue and trap blood clots therein. The device may be non-linear in plan view so as to conform to the shape of the external left atrium. Deployment techniques or structures may be provided that squeeze the LAA in a direction starting adjacent the left atrium and then moving away from the left atrium. This squeezing motion helps prevent extrusion of any thrombus deposit within the LAA cavity into the left atrium.

Left atrial appendage closure
Methods and apparatus for intraluminally or transluminally closing a left atrial appendage while under direct visualization are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for performing any number of procedures on the tissue for accessing and closing the left atrial appendage.

Exclusion of the left atrial appendage
A device for excluding the left atrial appendage (LAA) includes first and second members, each with first and second ends. The second ends are connected by a hinge.

Avatar pointing mode
A method of interacting with one or more objects in a virtual reality (VR) space. A user input establishes a pointing mode, whereupon a visual indicator, such as a pointer, is displayed on the user's viewing device, and the visual indicator is moved on the viewing device to refer to an object in the VR space, in response to actuation of a pointing device such as a mouse, joystick or pen. An image of the user's avatar may also be displayed in the VR space, and the avatar may have an appendage or pointing appliance to point to a target in the 3-D space. A user can point in this manner with high precision, as well as draw illustrations, etc. Other users (viewers) of the same VR space can see the first user's avatar pointing to the target. Another viewer's display can be dynamically adjusted to present an appropriate perspective of the VR space to show the target.
