A compacted vascular implant can be delivered to a target location within a delivery device. During delivery, the implant can be partially released from the delivery device before full deployment. The delivery device can include an elongated support tube, a locking mechanism, and a sheath. The locking mechanism can be provided on the support tube. The sheath can be configured to slide over the elongated support tube and can be configured to cover the locking mechanism and to restrain at least a portion of the implant.

The present invention provides modular intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or "prosthetic modules," may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module preferably includes one or more standard interface ends for engaging another module, the module / module interface typically comprising ends which overlap and / or lock within a predetermined axial range. Advantageously, the axial length, cross-section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner / tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module. The modules are preferably individually introduced into a lumen system of a patient body so that the composite prosthesis is assembled in situ. Ideally, selection of appropriate prosthetic modules and the flexibility of the interface overlap range provides a custom fit intraluminal prosthesis which provides a therapy tailored to the individual patient's needs.

A quick coupler formed of two identical sectors that snap lock together in a radially inward direction relative to a central axis of an annular hole passing through the coupler. The coupler is in the form of a nut or housing for surrounding the ends of two conduits that are to be coupled. The annular hole extends between opposite end faces and has structure near each end face. The structure at one end of the annular hole comprises a flange for retaining a first conduit when the sectors are snapped surroundingly snapped together on the end of the first conduit. The structure at the other end of the annular hole has circumferentially spaced lugs for cooperation with bosses on the second conduit in a bayonet quick coupling fashion. The combination of the coupler with first and second conduits having cooperating structure enabling the coupler to join the conduits in sealed fluid communication. The method of use of the combination comprises snap fitting the sectors onto an end of the first conduit by radially inward pressure.

A vehicle bed extender particularly adapted for ease of installation and removal. The extender includes a first side wall, a second side wall, a connecting wall, a first mount, a second mount, a first mounting station, and a second mounting station. The connecting wall, the first side wall, and the second side wall cooperate to form a generally U-shaped frame. The first mounting station and the second mounting station each comprise a stationary portion and a moveable portion configured such that the moveable portion, in a first position, cooperates with the stationary portion to engage the first mount or the second mount and to prevent disengagement. The moveable portion of the first mounting station and the second mounting station can be moved by a manual application of pressure to a second position which allows such disengagement.

An improved truck bed extender particularly adapted for ease of installation and removal. When not being used to extend the truck bed, the extender is advantageously adapted to quickly and easily create a secondary storage area. In one embodiment, the extender includes a first side wall, a second side wall, a connecting wall, a first mount and a second mount. The connecting wall extends between the first side wall and the second side wall, and cooperates with the first side wall and second side wall to form a generally U-shape frame. The first mount is secured to the first side wall and includes a first interlocking member. The second mount is secured to the second side wall and comprises a second interlocking member. The first interlocking member and the first mounting station on the vehicle and the second interlocking member and the second mounting station on the vehicle cooperate to secure the truck bed extender to the vehicle so that the extender is rotatable about an axis between a first and a second position. In the first position, the connecting wall is in an upright position over the tailgate beyond the rear end of the bed. In the second position, the connecting wall is in an upright position spaced forward from the rear end of the bed and the tailgate.

In certain embodiments, an entertainment system includes a housing configured to be mounted to a headrest. The housing can define a first hinge portion, a base wall, and one or more sidewalls. The housing can include a lock portion. In some embodiments, the system includes a screen assembly including a viewing screen. The screen assembly can define a second hinge portion that cooperates with the first hinge portion to pivotally couple the screen assembly with the housing. The screen assembly can further define an arm movable relative to the viewing screen. The arm can be configured to interact with the lock portion to retain the screen assembly in a stowed configuration in which the screen assembly is substantially prevented from moving away from the base wall of the housing. The arm further can be configured to be actuated to permit rotation of the screen assembly away from the base wall of the housing. In some embodiments, the system includes a headrest configured to be installed in a vehicle.

In the case of a pressure container comprising a plastic container core (2) for storing a fluid under pressure, a support sheath (3) surrounding the plastic container core (2), a connection piece (4) formed at the plastic container core (2) and having an opening (5) for filling in and discharging the fluid from the plastic container core (2), a connection body (6) arranged radially outside the connection piece (4) and having a bore (7), a valve body (8) having a fluid duct (9) for conducting the fluid in and out through the opening (5) in the connection piece (4), wherein the valve body (8) is arranged in the opening (5) of the connection piece (4) and in the bore (7) of the connection body (6), preferably at least one annular groove (10) formed radially outside in the valve body (8), one first seal (11) being arranged in each of the at least one radially outside annular groove (10), so that the at least one first seal (11) rests radially inside on the connection piece (4), the valve body (8) is to be attached reliably in a fluid-tight manner to the connection piece (4) of the plastic container core (2) and the valve body (8) and the connection body (6) have a small constructional height. This object is achieved by the fact that the connection body (6) has at least one radially inside annular groove (12) and that a second seal (13) is arranged in each of the at least one radially inside annular groove (12), so that the at least one second seal (13) rests radially outside on the connection piece (4).

A redundant release apparatus having a multi-segment split spool with a central bore adapted to axially restrain a tensioned member. Two tensioned tapes are overlappingly wound around the spool segments thereby preventing radial movement of the spool segments. Overlapping winding design of each of the tapes provide predictable unwinding dynamics upon release. The multiple segments require less radial motion for release of the tensioned member.

A bottle holder with an indented base, which has a body sized and shaped to receive a bottle. At least a portion of the body is radially expandable. A grip is attached to the exterior of the body and a securing base is located within the interior of the body. The securing base is sized and shaped to receive the indented base of a bottle and, when in use, to prevent radial movement of the bottle. When a bottle is inserted into the body, it is received by the indented base and is securely held in the bottle holder by the grip.
