    摘要: A dental prophylaxis angle is provided having a body having a sleeve sized for fitting the nose of a dental handpiece, a drive part comprising a drive shaft extending into the sleeve and a drive member on the drive shaft. A driven part comprising a driven part shaft. The drive and driven parts has axes of rotation which are at substantial angles to each other. The drive part shaft is sized for gripping by a gripping mechanism in the handpiece. The drive member has a forward surface and a post extending from its forward surface. The drive part post is sized to limit end play of the drive part. Additionally, the drive part post has a shallow cavity formed in a forward surface thereof to reduce the contact area of the post with the driven part shaft, and to provide a reservoir for lubricant in the angle.

    摘要: Shape memory alloy and elastically self-expanding endoluminal support structures which are at least partially encapsulated in a substantially monolithic expanded polytetrafluoroethylene (“ePTFE”) covering. An endoluminal stent, which has a reduced diametric dimension for endoluminal delivery and a larger in vivo final diametric diameter, is encapsulated in an ePTFE covering which circumferentially covers both the luminal and abluminal walls along at least a portion of the longitudinal extent of the endoluminal stent. The stent and ePTFE covering are helically wound into an open cylindrical configuration with adjacent windings forming overlapping regions of ePTFE covering bonded to one another. The shape memory endoluminal stent is fabricated from a shape memory alloy which exhibits either shape memory or pseudoelastic properties or from an elastic material having an inherent spring tension such as spring steel, braided stainless steel wire, or composite materials, such as woven or braided carbon fibers.
