A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.

The utility model discloses a quick-opening blind plate sealing ring which comprises a body with a saddle-shaped section, a first warped foot, a second warped foot and a third warped foot, the first warped foot, the second warped foot and the third warped foot are connected to the outer wall face of the body, the first warped foot and the second warped foot are oppositely arranged on the lower side of the body to form a first pressed inner cavity, and the third warped foot is arranged on the upper side of the body to form a second pressed inner cavity. An opening of the second pressure-bearing inner cavity faces the high-pressure raw material gas side, and the first pressure-bearing inner cavity is communicated with the second pressure-bearing inner cavity through a flat pressing hole; the first pressed inner cavity and the second pressed inner cavity which are communicated with each other are formed in the upper side and the lower side of the body with the saddle-shaped section, so that the first warping foot and the third warping foot generate upward horizontal pressure and outward horizontal pressure respectively, the body is attached to the sealing face of the quick-opening blind plate more tightly, and the quick-opening blind plate can be quickly opened along with continuous increase of the pressure. The first pressed inner cavity floats upwards to a certain degree, the gap between the blind plate cover and the lock ring can be compensated, and the phenomenon that the blind plate loses efficacy in the using process is avoided.

The utility model provides a saddle-shaped pipe fitting structure, and belongs to the technical field of saddle-shaped pipe fittings. The technical problem that an existing saddle-shaped pipe fitting joint is not convenient enough in butt joint operation is solved. The saddle-shaped pipe fitting structure comprises a saddle-shaped part, a branch pipe is arranged on the saddle-shaped part, an annular blocking shoulder is arranged at the end of the branch pipe, a butt-joint nut capable of freely rotating around the branch pipe is arranged on the periphery of the branch pipe in a sleeving mode, and an annular sealing edge is arranged on the inner edge of the butt-joint nut. And the sealing edge is limited and matched between the saddle-shaped part and the retaining shoulder along the axial direction of the branch pipe. The saddle-shaped pipe fitting is high in structural applicability, and the connecting convenience of the saddle-shaped pipe fitting can be effectively improved.

Newness and distinctiveness reside in the visual features, including shape, configuration and / or pattern, of a SADDLE-MOUNTING BRACKET ASSEMBLY as shown in the accompanying drawing.

The invention belongs to the technical field of bolt and nut locking, and relates to a bolt and nut locking device. The bolt comprises a bolt head, a bolt column, a nut, a flat washer and a saddle-shaped elastic washer, the bolt head is connected to one end of the bolt column. The nut is in threaded connection with the bolt column. A slot is formed in the flat washer, and one side of the saddle-shaped elastic washer is matched with the slot in an inserting manner; and after one side of the saddle-shaped elastic washer is inserted into the slot, the flat washer and the saddle-shaped elastic washer form a V shape. Compared with a traditional method that a nut is screwed to a bolt head in a long stroke to prevent scattering, the device has the advantages that the flat washer and the saddle-shaped elastic washer are designed to be of the V-shaped structure capable of being combined in an inserted mode, so that the nut only needs to be screwed into a short stroke, enough elastic deformation and friction force can be generated by extruding the saddle-shaped elastic washer, and the temporary locking state is achieved. The process is labor-saving and quick to operate. During formal installation, additional complex operation is not needed, the workload of assembly workers is reduced on the whole, and the working efficiency is improved.
