Apparatus for delivering a sleeve into a puncture through tissue includes a tubular sheath including a lumen extending between its proximal end and an opening in its distal end. The sleeve includes a hub on a first end thereof disposed adjacent the distal end of the sheath, and a second end extending into the opening and lumen of the sheath. The hub is slidable along an exterior of the sheath for drawing the sleeve out of the opening and along an exterior of the sheath. During use, a guide wire is placed through the puncture into a blood vessel, and sealing compound is introduced into the puncture around the guide wire. The sheath is advanced into the puncture over the guidewire while maintaining the hub adjacent the patient's skin, causing the sleeve to be deployed from the sheath and line the puncture as the sheath is advanced into the puncture.
L~invention concerne un appareil permettant d~installer un manchon dans une piqûre à travers un tissu, englobant une gaine tubulaire comprenant un lumen s~étendant entre son extrémité proximale et une ouverture en son extrémité distale. Le manchon comporte un moyeu sur une première extrémité idoine disposée adjacente de l~extrémité distale de la gaine, et une seconde extrémité s~étendant dans l~ouverture et le lumen de la gaine. Le moyeu peut coulisser le long de l~extérieur de la gaine afin d~extraire le manchon de l~ouverture et le long de l~extérieur de la gaine. En service, on place un fil de guidage à travers la piqûre dans un vaisseau sanguin et l~on introduit le composé d~étanchéité dans la piqûre autour du fil de guidage. On fait avancer la gaine dans la piqûre au-dessus du fil de guidage tout en maintenant le moyeu adjacent de la peau du patient, pour alors déployer le manchon à partir de la gaine et doubler la piqûre pendant la progression de la gaine dans la piqûre.
