Patent

CA 2451084

An introducer comprises a sheath, a guide rod, and at least one wire stabilization guide. The guide rod is sized to fit within the inside diameter of the sheath. The guide rod has at least one slot along its length for releasably holding the wire stabilization guide. One or more wire stabilization guides are coupled to the sheath. In one exemplary embodiment, the wire stabilization guides are inserted into a wound site and are dimensioned so as to cause an outward stretching force on the wound site. In another embodiment, the wire stabilization guides may form a loop, so that when the sheath is approximated to a wound site, the loop is approximated to tissue surrounding the wound site to hold the sheath approximately centered on the wound site. In other embodiments, the wire stabilization guides may include a retention device to hold the sheath approximate to the wound site.

L'invention concerne un introducteur comprenant une gaine, une tige de guidage et au moins un guide de stabilisation de fil. Ladite tige de guidage est dimensionnée de façon à s'ajuster dans le diamètre intérieur de la gaine. Elle comprend au moins une fente sur sa longueur afin de maintenir libérable ledit guide de stabilisation de fil. Au moins un guide de stabilisation de fil est couplé à cette gaine. Dans un mode de réalisation exemplaire, les guides de stabilisation de fil sont introduits dans un site de plaie et sont dimensionnés de façon à appliquer une force d'étirage vers l'extérieur sur ledit site. Dans un autre mode de réalisation, les guides de stabilisation de fil peuvent former une boucle, de sorte que lorsque la gaine se trouve près du site de plaie, la boucle se trouve près du tissu entourant ledit site de plaie de façon à maintenir ladite gaine approximativement centrée sur ce site de plaie. Dans d'autres modes de réalisation, les guides de stabilisation de fil peuvent comprendre un dispositif de retenue permettant de maintenir la gaine à proximité du site de plaie.
