Definitions

  • FIG. 7 illustrates another embodiment of the present invention with a retaining ring affixed to the gasket of Figs. 2 and 3.
  • the housing contains a self-sealing hemostasis gasket 8 having a geometry illustrated in FIGS. 2 and 3 and in the aforementioned U.S. patent 5,304,156 and
  • FIGS. 2 and 3 illustrate the gasket which is geometrically similar to that disclosed in U.S. patent 5,304,156 and application serial no. 08/058,594.
  • the gasket 8 differs f om the gaskets described in the patent and application in several respects.
  • the gasket 8 is thinner, of the order of 0.050 inch thickness.
  • central aperture 304 in the proximal face of the gasket although the same diameter as in the above-referenced patent and application (0.029 inch) is not as deep, being of the order of 0.020 inch because the gasket 8 is substantially thinner than that disclosed in the patent.
  • the gasket While the entire radial length of the slits does not freely move, the depth of the slits cut into the surface of the gasket weakens that surface allowing, in addition to the overlapping of the central aperture and the slits, the gasket to give way when a large diameter catheter is inserted through the gasket while maintaining the ability to seal around small diameter guidewires as well as due to the presence of the small diameter central aperture.

Abstract

La présente invention concerne un joint d'étanchéité auto-obturant amélioré maintenant l'hémostase tout en réduisant la force requise pour déplacer un cathéter ou un fil-guide placé dans ledit joint. Des fentes pratiquées sur l'une des faces du joint étanche se rejoignent au niveau d'un orifice central ménagé sur la surface opposée du joint d'étanchéité. La retenue du joint dans l'embout d'introduction du cathéter est facilitée par un anneau circulaire réalisé sur le joint étanche. Un épaulement annulaire peut être prévu sur la face distale du joint d'étanchéité permet d'empêcher son dégagement en cas d'introduction désaxée d'un instrument dans l'embout.
