Abstract: A system for use with an endoscopic device. The system can include a shaft having a proximal end, a distal end, and at least one output port, wherein a portion of the shaft is surrounded by a single polyurethane expandable material, wherein the polyurethane expandable material is expandable from a diameter of at least approximately 5.0 mm to a diameter of approximately 25 mm. The system can also include a manifold connected to the proximal end of the shaft, the manifold including one or more fluid coupling ports for receiving an injected fluid, wherein at least one of the one or more fluid coupling ports is in fluid communication with the at least one output port and wherein when received, the system is configured to convey the injected fluid from the manifold to the shaft resulting, at least in part, in expanding the polyurethane expandable material.

Abstract: Briefly, in accordance with one embodiment, a tool for use with an endoscopic procedure comprises an expandable thermoplastic polyurethane vessel. The expandable vessel may be fused to a shaft and may be configured to receive a fluid from the shaft. The shaft may comprise a distal port and a proximal port configured to dispense a dye material exterior to the expandable vessel.

Abstract: Embodiments of the invention allow users to generate and maintain space objects in a computer-aided design model representing regions bounded by a set of drawing elements included in the model. The space object contains the geometry of such a bounded region and may be used to calculate values such as area and volume associated with the region. Additionally, each space object may be associated with the set of drawing elements bounding the region represented by the space object such that any changes to one of the associated bounding elements causes the geometry of the space object to be updated automatically to reflect these changes. Areas and volumes calculated from the space object geometry may conform to established standards regarding the calculation of gross, net and useable areas of a building or other structure.

Abstract: A reordering tool for sequentially reordering data values assigned to graphical objects in a CAD model is described. The reordering tool can be a software application or a tool included in a software application. The reordering tool can have one or more graphical user interfaces configured to receive input from a user and present information to a user prior to reordering data values of the objects.

Abstract: One or more embodiments of the invention provide a method, apparatus, system, and article of manufacture for indicating available modifications to a geometric object in a computer drawing program. A three-dimensional geometric object is displayed in a computer drawing program. Additionally, an oriented three-dimensional glyph is displayed. The oriented three-dimensional glyph provides a direct visual indication of valid movement direction during direct manipulation of the three-dimensional geometric object.
