Abstract: Corner studs for prefabricated building systems are presented. The corner studs have an angled side that when interconnected with the angled side of another such stud forms a complete, structurally sound corner. The studs can be fabricated such that they can form corners of various angles. For example, corner studs can be fabricated to form corners of substantially 90°, 108° (e.g., used in pentagonal structures), or 120° (e.g., used in hexagonal structures). Galvanized metal, stainless steel, wood, suitable plastics, and other suitable materials can be used to fabricate the studs. The corner studs can have solid or hollow interiors with various cross-sectional configurations.

Abstract: Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced.
