Embolic filter frame having looped support strut elements

InactiveUS20040093012A1Longitudinal compliance be enhanceImprove sealingSurgeryDilatorsEngineeringLower degree
An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of "radial" stiffness with a low degree of "longitudinal" stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts "snap open" and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts and the central collar connecting the support struts to the support wire, are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter is therefore reduced.

Machining device and machining technology for glass sheet hot bending molding

The invention relates to the field of glass sheet hot bending molding, in particular to a machining device and machining technology for glass sheet hot bending molding. The machining device and machining technology finish machining through a jig structure and the simple process. The machining device mainly comprises a whole rack and a supporting part. The whole rack is of a rack structure with the periphery sealed and a cavity inside. The supporting part is arranged under the whole rack to support the whole rack. The inner cavity of the whole rack is sequentially and transversely provided with a preheating area, a molding area and a cooling area from left to right. Isolation areas are installed at the left end and the right end of the outer side of the whole rack. Meanwhile, the whole rack is provided with a conveying rail which is communicated with the isolation areas at the two ends and connected with the preheating area, the molding area and the cooling area. Glass sheets are loaded and pressed through a jig so as to finish the whole process of glass sheet hot bending molding. Loading performance of the graphite jig is stable, pressing and heating of the jig are uniform, the structure of the whole machining device is simplified, and the machining technology is simple.
