摘要:
A tape-reinforced tubular vascular graft formed of sintered fluoropolymer(s), such as expanded, sintered PTFE. The graft includes a base graft and a reinforcing tape applied thereto. The tape may be spirally wrapped about the graft or spirally wrapped into a tube about a cylindrical mandrel and then applied to the exterior of The graft. Radial shrinkage of the combined base graft and tape, or of the reinforcing tape tube, renders the vascular graft subsequently radially enlargeable by more than 5%, without tearing or breaking of the reinforcement tape layer of the graft. Radially enlargeable grafts of the present invention may be combined with various types of stents or anchoring systems, to form endovascular graft devices which are transluminally insertable and implantable within the lumen of a host blood vessel. Alternatively, radially enlargeable grafts of the present invention may be implanted by way of traditional surgical graft implantation techniques, without any radial enlargement of the graft at the time of implantation, so as to take advantage of the improved strength properties and suture-holding properties of the radially-shrunken tape-reinforced grafts of the present invention.

Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.

An air travel system preferably uses an airport terminal or concourse that includes at least one regional aircraft boarding pier and at least one boarding bridge for larger aircraft. The regional aircraft boarding pier includes a primary passenger bridge extending from the airport terminal or concourse; a pier hub connected to the primary passenger bridge; and a plurality of secondary passenger bridges connected to, and extending from, the hub. Each secondary passenger bridge has a docking end for docking with a regional aircraft. A method of operating this air travel system includes boarding a passenger on a regional aircraft by sending the passenger through the regional aircraft boarding pier. This may be before or after the passenger also uses a boarding bridge to board a larger aircraft which is a connecting flight in the passenger's travel itinerary. This method allows the passenger to transfer between regional and larger aircraft within a single airport concourse or terminal.

A guy marker apparatus for use on an associated guy wire includes a substantial rectangular body member having opposite parallel first and second edges and is foldable along a longitudinal axis parallel with the first and second edges. First and second connection portions are disposed at the first and second edges, respectively, for selectively interlocking the edges in slidable abutment to hold the main body member in a folded tubular conformation and selectively in a helical conformation. A tool for applying a guy marker apparatus onto an associated guy wire includes a main body member, an alignment portion adapted to guide the guy marker in an unlocked state relative to the main body member, and a production portion adapted to guide the marker in a self-locked state out from the main body member. A forming wall disposed between the alignment and production portions moves. the marker material between the unlocked and self-locked state based on relative movement between the tool and the guy marker material. A dispensing system for a bulk roll of coiled guy marker material includes a housing having a cavity adapted to hold the coil of guy marker material having a shape memory. The housing includes an outlet opening whereby desired lengths of guy marker material may be drawn. The bulk roll includes coiled flattened layers of plastic guy wire marker material having an inherent shape memory characteristic.

A corn inbred designated 3B703 is disclosed. The invention relates to the seeds of corn inbred 3B703, to the plants of corn inbred 3B703, to plant parts of corn inbred 3B703 and to methods for producing a corn plant produced by crossing corn inbred 3B703 with itself or with another corn variety. The invention also relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic corn plants and plant parts produced by those methods. This invention also relates to corn inbreds or breeding inbreds and plant parts derived from corn variety 3B703, to methods for producing other corn inbreds and lines or plant parts derived from corn inbred 3B703 and to the corn plants, varieties, and their parts derived from use of those methods. The invention further relates to hybrid corn seeds, plants and plant parts produced by crossing the inbred 3B703 with another corn inbred.
